Put routes in `src/pages/`, reusable UI in `src/shared/components/`, application features in `src/features/`, state in `src/store/`, and static files in `public/`. +- `be-ircfa/` is the Python 3.11+ FastAPI service. API domains live under `src/` (for example, `src/rag/` and `src/root_cause/`); keep each domain's router, model/schema, and service together. Tests live in `tests/`, with unit tests in `tests/unit/`. + +Both directories have their own Git repository; run Git commands from the application being changed. + +## Build, Test, and Development Commands + +Run commands from the relevant application directory. + +- `cd fe-digitaltwin-v2 && npm install` installs frontend dependencies. +- `npm run dev` starts Vite at port 3002; `npm run build` type-checks and creates the production bundle; `npm run lint` runs ESLint; `npm run preview` serves the built bundle. +- `cd be-ircfa && make install` installs Poetry dependencies, `make run` starts the service, and `make test` runs `pytest tests/unit/` with the project on `PYTHONPATH`. + +## Coding Style & Naming Conventions + +Follow the backend `.editorconfig`: four spaces, LF endings, trimmed trailing whitespace, and a final newline (tabs in `Makefile`). Use `snake_case` for Python modules and functions; group backend code by feature with files such as `router.py`, `service.py`, and `model.py`. + +Use TypeScript for frontend changes. Components and page files use PascalCase (for example, `DashboardPage.tsx`); hooks use the `use-` / `use` pattern (for example, `use-debounce.tsx`). Prefer configured `@/` aliases over deep relative imports, and reuse existing design-system components and tokens. Run ESLint before submitting frontend changes. + +## Testing Guidelines + +Add or update backend pytest coverage alongside behavioral changes; name test files `test_*.py` and tests `test_*`. Run `make test` before review. The frontend currently exposes lint and production-build checks rather than a test script, so run both `npm run lint` and `npm run build` for frontend work. + +## Commit & Pull Request Guidelines + +Frontend history commonly uses Conventional Commit prefixes such as `feat:`, `fix:`, and `chore:`; use concise imperative subjects (for example, `feat: add RCFA export filter`). Keep commits scoped to one application and concern. Pull requests should explain the user-visible change, list validation performed, link the relevant issue when available, and include screenshots for UI changes. Do not commit secrets, local `.env` files, debug exports, or generated build output. diff --git a/COMPARISON.md b/COMPARISON.md new file mode 100644 index 0000000..a0e57db --- /dev/null +++ b/COMPARISON.md @@ -0,0 +1,40 @@ +# RCFA Memory Variant Comparison + +## Versions + +- `/home/nvidia/dev-rcfa` is the restored application as it existed before the private-memory changes. +- `/home/nvidia/dev-rcfa-memory` is the comparison copy with private, explicit-only memory behavior. + +The original application already contained an `RCFAMemory` table and retrieval path.

However, the system treats all images equally and all documents as flat text, losing critical visual information from P&ID diagrams, thermal images, vibration plots, and equipment photos that are vital for RCFA at a coal-fired power plant. + +**Key Opportunities (Ranked by Impact):** + +1. **P&ID Diagram Understanding** — Currently treated as flat text via OCR. A multimodal LLM can read valve tags, trace piping, identify flow direction, and locate equipment in the plant layout. This is the single highest-value improvement. +2. **Equipment Photo Analysis** — Failure evidence photos (corrosion, cracks, leaks) are passed to the LLM without preprocessing or structured prompting. Adding visual inspection context and failure taxonomy alignment would dramatically improve root cause identification. +3. **Table & Chart Extraction from PDFs** — Maintenance reports, vibration spectra, and thermal scans contain tabular/visual data that Docling flattens into text. Native multimodal processing preserves structure. +4. **Document-Type Classification** — All attachments processed identically. Classifying documents (P&ID, maintenance report, FMEA sheet, equipment photo) before processing allows type-specific prompt engineering and tool routing. +5. **Image Preprocessing Pipeline** — No resize, enhancement, or quality normalization before base64 encoding. Scanned field photos with poor lighting or blurry text degrade LLM performance. +6. **Cross-Modal Context Fusion** — Images and tool data (sensor readings, reliability metrics) are processed in isolation. Fusing visual evidence with quantitative data in a single prompt gives the LLM richer context for root cause analysis. + +**Estimated Impact:** These improvements are expected to reduce repeated analysis turns and improve evidence grounding for visual-evidence-dependent failure modes (corrosion, erosion, thermal damage, mechanical wear). Exact gains in RCFA accuracy and response time must be validated through benchmark cases before being used as delivery targets. + +--- + +## 1.

Revision Notes And Implementation Judgment + +This revision tightens the original analysis so it can be used safely as an implementation reference for iRCFA on a specific coal power plant unit. The core direction remains valid: the app already has a basic multimodal path, but the highest-value improvement is not simply "send more images to the LLM." The highest-value improvement is structured evidence fusion across attachment content, unit context, location tag, plant data, reliability predictions, and RCFA phase. + +### 4.1 Confirmed Current Behavior + +- `stream2.py` supports basic multimodal image routing by separating image attachments from document attachments. +- `GemmaLlamaCppLLM` injects up to 3 image files as base64 `image_url` parts into the final OpenAI-style chat payload. +- Documents are currently reduced to extracted text or markdown before being appended to the reasoning context. +- Docling may preserve some table or layout information in markdown, but the current app does not route documents by document type or preserve visual structure as first-class RCFA evidence. +- Tool outputs and visual evidence are not explicitly fused into a structured RCFA evidence packet before final reasoning. + +### 4.2 Corrections To Original Claims + +- Accuracy improvement numbers such as `~70%` to `~90%+` should be treated as target hypotheses, not confirmed outcomes. +- Time reduction numbers such as `40-60%` should be treated as expected directionality until measured against real or representative RCFA cases. +- P&ID support should be framed as P&ID-assisted tag, equipment, and relationship extraction requiring human verification, not autonomous full structural analysis. +- Multimodal output must be treated as engineering decision support. It should help technicians and reliability engineers inspect evidence, compare hypotheses, and prepare RCFA reasoning, but it should not be treated as authoritative diagnosis without human review. + +### 4.3 Revised Priority + +The implementation priority should shift from generic image understanding to unit-bound evidence fusion: + +1. Attachment classification: identify whether the upload is an equipment photo, P&ID, thermal image, vibration chart, DCS screenshot, maintenance report, FMEA sheet, or generic document. +2. Unit/location-tag binding: connect each attachment to an explicit unit, equipment, system, and location tag where available. +3. Structured RCFA evidence packet: combine image/document evidence with current sensor data, historical sensor data, reliability metrics, PFI/RP predictions, SPLN/FMEA records, and current RCFA phase. +4.

Molded Case Circuit Breaker (MCCB) Latching Mechanism Failure Grease Hardening MCCB tidak dapat diubah ke posisi "ON". Saat tuas dinaikkan, ia tidak mengunci dan langsung kembali ke posisi "TRIP" atau "OFF"; Motor DC tidak dapat di-start sama sekali. Jika ini adalah pompa Emergency, kesiapan unit pembangkit terganggu (Unavailability of Safety System); Tuas terasa berat atau "kenyal" saat dioperasikan; Saat mencoba me-reset (ke posisi OFF lalu ke ON), tuas tidak mau diam di posisi atas; Tidak ada indikasi gangguan elektrik, murni masalah mekanis; Coba operasikan tuas ON-OFF-RESET berulang kali (5-10 kali) dengan cepat. Gesekan dapat memanaskan sisa pelumas. Jika setelah beberapa kali tuas mulai bisa mengunci, terkonfirmasi masalah pelumas beku; Dengarkan suara "Klik". Jika suaranya lemah atau tidak terdengar saat tuas dinaikkan, mekanisme latch terhambat grease; Schedule Maintenance (PM): Pembersihan panel; Operasional rutin (Exercise) untuk mencegah stagnasi; Lakukan "Exercising" (On-Off berulang) untuk memecah kekakuan pelumas; ika MCCB tipe Serviceable (Air Circuit Breaker bisa, tapi MCCB biasanya sealed), lakukan pelumasan ulang. Namun untuk MCCB molded, GANTI BARU adalah solusi standar jika exercising tidak berhasil, karena mekanisme internal sulit diakses tanpa merusak casing; Pastikan pemanas panel (Heater) dan ventilasi bekerja agar suhu panel stabil, mencegah grease cepat kering; +K3 & LH (KLH), Air Flue Gas (AFG), Boiler (BOL), Sis Pemakaian Sendiri (SPS), Ash Handling (ASH), Coal Handling (CH), Chlorination (CP), Water Treatment Plant (WTP), Generator (GEN), FGD Support (SUP), Screen & Filter (SCR) DC Motor Starter Panel DC Motor Starter Panel 3ABS-PAN861, 3AF-M501A, 3AH-PAN571A, 3AI-PAN501A, 3AI-PAN501B, 3AI-PAN501C, 3AL-M501A, 3AL-M501B, 3APC-MCC502A, 3APC-PD501A, 3APC-PD502, 3APC-PD891, 3APC-PD894, 3APC-PD901, 3APC-PD910, 3APC-PD921, 3APC-PD951, 3BAD-PAN501, 3BAD-PAN503, 3BAD-PAN504, 00CHA-PAN801A, 00CHA-PAN814, 00CHA-PAN824, 00CHA-PAN848, 00CHA-PAN854, 00CHA-PAN858, 00CHB-PAN805A, 00CL-PAN001, 00DMW-CAB100, 00DMW-CAB105A, 3EG-PAN002, 3EVM-PAN801, 3GEN-CAB002A, 3GEN-EXC006, 3GEN-CAB003A, 3GEN-CAB007A, 3GG-T801A, 4GG-T801A, 3GG-DAX501, 3H2-LP002, 00LSH-PAN801, 00LSH-PAN802, 00LSH-PAN803, 00LSH-PAN804, 00LSH-PAN862, 00LSH-PAN863, 00LSH-PAN865, 00LSH-PAN866, 00RO-CAB200, 00RO-CAB205, 00RO-CAB225A, 00RO-CAB245A, 00RO-CAB255A, 00RO-CAB275, 00RO-CAB280, 00RO-CAB285, 3SCR-PAN001, 3SCR-PAN002A, 00SSB-EV011, 3TR-CAB004A, 3TR-CAB010 Menyalurkan daya listrik DC ke motor.

Molded Case Circuit Breaker (MCCB) Latching Mechanism Failure Latch Surface MCCB sering trip sendiri (Nuisance Trip) saat ada getaran kecil, atau tidak bisa dikunci (ON) sama sekali karena latch selip (slip); Terputusnya daya ke motor DC secara tiba-tiba tanpa adanya arus lebih. Kehilangan keandalan proteksi; MCCB trip tiba-tiba saat ada pintu panel ditutup keras atau ada vibrasi mesin di sekitar (shock sensitive); Tuas bisa dinaikkan, tapi "lepas" lagi hanya dengan sentuhan ringan; Lakukan Vibration Test. Saat MCCB dalam posisi ON (jika bisa), ketuk body MCCB perlahan dengan gagang obeng karet. Jika langsung trip, permukaan latch sudah kritis (tidak mampu menahan guncangan); Secara visual, kegagalan ini hanya bisa dilihat jika MCCB rusak dibongkar (destruktif); Standar uji ketahanan mekanis (Mechanical Endurance Test IEC 60947); Mounting panel dengan rubber damper untuk mengurangi vibrasi; Komponen internal latch yang aus pada MCCB tidak dapat diperbaiki/ditambal.

Molded Case Circuit Breaker (MCCB) Internal Contact High Resistance Pitting Corrosion Titik kontak yang sempit menanggung kepadatan arus (current density) yang sangat tinggi, memicu panas ekstrem lokal (hotspot); Risiko kontak menjadi las (welded) saat terjadi arus inrush atau gangguan berikutnya. Suplai daya menjadi tidak andal (unreliable); Tegangan output tidak stabil (fluctuating voltage) di sisi beban; Suhu terminal MCCB tinggi (panas merambat dari kontak internal ke terminal luar); Lakukan Micro-ohm Meter (Ductor). Ini adalah metode paling akurat. Bandingkan nilai resistansi antar pole (misal Pole Positif vs Pole Negatif). Perbedaan >20-50% menandakan salah satu kontak mengalami erosi parah; Lakukan Voltage Drop Test. Ukur beda tegangan antara terminal Line dan Load saat motor beroperasi. Drop tegangan yang tinggi (>100mV atau sesuai standar) menandakan resistansi internal; Material kontak Silver Alloy (tahan erosi); Mekanisme Quick-Make/Quick-Break; Kontak yang sudah mengalami pitting parah tidak dapat diperbaiki.

Molded Case Circuit Breaker (MCCB) Internal Contact High Resistance Formation of Oxide/Sulphide Films Resistansi kontak menjadi sangat tinggi saat arus rendah, atau kontak seolah-olah terbuka (Open Circuit) padahal tuas ON; "Gagal Start Halus". Motor mungkin tidak mau start saat tombol ditekan karena arus kontrol tidak mampu menembus lapisan film, atau terjadi panas tinggi mendadak saat lapisan film tembus (fritting); Motor kadang jalan kadang tidak (intermittent failure); Terminal MCCB terlihat menghitam (jika terlihat) atau body sangat panas; Cek apakah terminal tembaga luar juga menghitam? Jika ya, kemungkinan besar kontak dalam juga terserang sulfidasi; Lakukan Ductor Test. Nilai resistansi akan sangat tinggi atau Open (Infinite); Penggunaan Space Heater di dalam panel untuk menjaga kelembaban rendah; Desain panel IP rating tinggi (Seal pintu yang baik); Lakukan switching ON-OFF beberapa kali. Gesekan mekanis kontak biasanya cukup untuk menggores dan memecahkan lapisan film sulfida (self-cleaning); Pastikan pemanas panel (anti-condensation heater) berfungsi 24 jam.

Magnetic Contactor (Main Contacts) Chattering Unstable DC Supply Kerusakan mekanis pada inti besi (core hammering) dan risiko koil panas. Kontak utama mengalami arcing hebat yang memicu erosi cepat atau welding; Suplai daya ke motor terputus-nyambung dengan cepat. Arus inrush motor terjadi berulang kali, berpotensi merusak isolasi motor dan memutus Fuse/MCCB di sisi hulu; Suara "tek-tek-tek" atau dengungan kasar (buzzing) yang berirama dari panel; Lampu indikator di panel berkedip (flickering) seirama dengan suara chattering; Alarm DC Undervoltage mungkin muncul sesaat di DCS; Ukur tegangan di terminal koil (A1-A2) menggunakan Multimeter dengan mode Min/Max Capture. Cek apakah tegangan jatuh di bawah ambang batas kerja kontaktor (misal <85V untuk sistem 110V); Jika tersedia, cek kualitas tegangan DC (ripple) dari output Battery Charger dengan osiloskop Relay DC Undervoltage (UVR) pada panel distribusi; Kapasitas Battery Bank yang didesain untuk holding time tertentu; Periksa kondisi Battery Bank (Cell Impedance Test) dan Charger (Rectifier). Pastikan tidak ada sel baterai yang open/short yang menyebabkan tegangan tidak stabil saat beban hentakan; Jika instabilitas disebabkan oleh dip sesaat saat starting beban besar lain, pertimbangkan memasang kapasitor penstabil atau time-delay pada rangkaian kontrol (jika diizinkan oleh standar safety) +K3 & LH (KLH), Air Flue Gas (AFG), Boiler (BOL), Sis Pemakaian Sendiri (SPS), Ash Handling (ASH), Coal Handling (CH), Chlorination (CP), Water Treatment Plant (WTP), Generator (GEN), FGD Support (SUP), Screen & Filter (SCR) DC Motor Starter Panel DC Motor Starter Panel 3ABS-PAN861, 3AF-M501A, 3AH-PAN571A, 3AI-PAN501A, 3AI-PAN501B, 3AI-PAN501C, 3AL-M501A, 3AL-M501B, 3APC-MCC502A, 3APC-PD501A, 3APC-PD502, 3APC-PD891, 3APC-PD894, 3APC-PD901, 3APC-PD910, 3APC-PD921, 3APC-PD951, 3BAD-PAN501, 3BAD-PAN503, 3BAD-PAN504, 00CHA-PAN801A, 00CHA-PAN814, 00CHA-PAN824, 00CHA-PAN848, 00CHA-PAN854, 00CHA-PAN858, 00CHB-PAN805A, 00CL-PAN001, 00DMW-CAB100, 00DMW-CAB105A, 3EG-PAN002, 3EVM-PAN801, 3GEN-CAB002A, 3GEN-EXC006, 3GEN-CAB003A, 3GEN-CAB007A, 3GG-T801A, 4GG-T801A, 3GG-DAX501, 3H2-LP002, 00LSH-PAN801, 00LSH-PAN802, 00LSH-PAN803, 00LSH-PAN804, 00LSH-PAN862, 00LSH-PAN863, 00LSH-PAN865, 00LSH-PAN866, 00RO-CAB200, 00RO-CAB205, 00RO-CAB225A, 00RO-CAB245A, 00RO-CAB255A, 00RO-CAB275, 00RO-CAB280, 00RO-CAB285, 3SCR-PAN001, 3SCR-PAN002A, 00SSB-EV011, 3TR-CAB004A, 3TR-CAB033 Menyalurkan daya listrik DC ke motor.

Magnetic Contactor (Main Contacts) Chattering Dirty Pole Faces Panas berlebih pada koil (pada tipe AC ini fatal, pada tipe DC menyebabkan daya tarik lemah). permukaan inti besi menjadi cacat/berlubang (mushrooming); Kontak utama tidak menekan sempurna (low contact pressure), menyebabkan High Resistance, panas berlebih pada terminal, dan risiko kebakaran panel; Suara dengungan (Humming) yang konstan dan keras dari kontaktor (beda dengan suara "tek-tek", ini lebih ke suara getaran frekuensi mains/ripple); Ditesurfacen serbuk karat halus berwarna coklat atau hitam di dasar panel tepat di bawah kontaktor; Bongkar casing koil/armature. Cek permukaan pole faces. Biasanya terlihat kotoran hitam (debu batubara+grease) atau karat; Selipkan selembar kertas di antara inti besi, tekan manual. Jika kertas mudah ditarik keluar, permukaan tidak rata/kotor; Filter debu pada ventilasi panel; Lapisan anti-karat (Varnish) pada inti laminasi besi; Bersihkan permukaan inti besi dengan kain majun bersih dan cairan pembersih kontak (contact cleaner) atau alkohol. JANGAN menggunakan amplas kasar karena akan merusak lapisan laminasi dan memperburuk dengungan. JANGAN memberi grease karena akan menangkap debu lagi; Jika permukaan inti sudah berkarat parah (pitting), ganti unit kontaktor.

Magnetic Contactor (Main Contacts) Chattering High Resistance in Pilot Circuits Koil berusaha menutup tapi tidak kuat (hovering), menyebabkan kontak utama bersentuhan ringan dan memicu sparking; Operasi motor menjadi intermittent (mati-hidup sendiri). Kesulitan saat start-up pertama. Sinyal status ke DCS menjadi tidak valid; Tegangan di Busbar Control normal (misal 110V), tetapi tegangan terukur di koil kontaktor drop (misal hanya 90V atau berfluktuasi); Chattering sering terjadi saat ada getaran fisik di panel (misal pintu ditutup); Dalam kondisi energized, ukur tegangan bertahap dari sumber (+) melewati fuse, tombol, relay, hingga ke koil. Cari titik di mana tegangan drop drastis; Cek terminal-terminal rangkaian kontrol (pilot devices) untuk mencari titik panas (hotspot) akibat koneksi longgar; Penggunaan Ferrule pada ujung kabel serabut; Standar Torsi Pengencangan Terminal; Lakukan pengencangan ulang seluruh terminal kontrol (control terminal block) secara berkala, terutama di area dengan vibrasi tinggi; Ganti tombol tekan (push button) atau kontak bantu (aux contact) yang sudah tua dan memiliki resistansi kontak tinggi.

Magnetic Contactor (Main Contacts) Contact Erosion/Wear Material Migration (DC Specific) Pengurangan luas permukaan kontak efektif. Terjadinya "Mechanical Locking" (saling mengunci) antara tonjolan dan lubang, yang bisa menyebabkan gagal buka atau kontak tidak rapat; Peningkatan resistansi kontak yang menyebabkan tegangan jatuh (voltage drop). Motor DC menerima tegangan di bawah nominal, mengurangi torsi/RPM, atau kehilangan daya total jika kontak menjadi Open Circuit akibat erosi dalam; Tegangan output tidak seimbang atau rendah saat diukur di sisi beban (Load side); permukaan kontak terlihat tidak rata secara ekstrem (ada jendolan dan lubang) saat inspeksi visual; Lihat profil samping kontak. Jika terlihat bentuk "gunung dan lembah" yang saling berpasangan, ini adalah migrasi material; Ukur dengan Micro-ohm meter; Penggunaan material kontak khusus DC (Silver-Tin Oxide atau Silver-Tungsten) yang lebih keras dibanding perak murni; Inspeksi PM Rutin; Ganti kontak (Fixed & Moving) satu set. Jangan mengikir/mengamplas tonjolan tersebut karena akan menghilangkan lapisan coating perak dan mempercepat korosi; Pastikan polaritas pemasangan kabel sesuai (meskipun pada kontaktor bi-directional modern ini kurang kritikal, namun pada tipe lama arah arus mempengaruhi sisi mana yang tergerus); +K3 & LH (KLH), Air Flue Gas (AFG), Boiler (BOL), Sis Pemakaian Sendiri (SPS), Ash Handling (ASH), Coal Handling (CH), Chlorination (CP), Water Treatment Plant (WTP), Generator (GEN), FGD Support (SUP), Screen & Filter (SCR) DC Motor Starter Panel DC Motor Starter Panel 3ABS-PAN861, 3AF-M501A, 3AH-PAN571A, 3AI-PAN501A, 3AI-PAN501B, 3AI-PAN501C, 3AL-M501A, 3AL-M501B, 3APC-MCC502A, 3APC-PD501A, 3APC-PD502, 3APC-PD891, 3APC-PD894, 3APC-PD901, 3APC-PD910, 3APC-PD921, 3APC-PD951, 3BAD-PAN501, 3BAD-PAN503, 3BAD-PAN504, 00CHA-PAN801A, 00CHA-PAN814, 00CHA-PAN824, 00CHA-PAN848, 00CHA-PAN854, 00CHA-PAN858, 00CHB-PAN805A, 00CL-PAN001, 00DMW-CAB100, 00DMW-CAB105A, 3EG-PAN002, 3EVM-PAN801, 3GEN-CAB002A, 3GEN-EXC006, 3GEN-CAB003A, 3GEN-CAB007A, 3GG-T801A, 4GG-T801A, 3GG-DAX501, 3H2-LP002, 00LSH-PAN801, 00LSH-PAN802, 00LSH-PAN803, 00LSH-PAN804, 00LSH-PAN862, 00LSH-PAN863, 00LSH-PAN865, 00LSH-PAN866, 00RO-CAB200, 00RO-CAB205, 00RO-CAB225A, 00RO-CAB245A, 00RO-CAB255A, 00RO-CAB275, 00RO-CAB280, 00RO-CAB285, 3SCR-PAN001, 3SCR-PAN002A, 00SSB-EV011, 3TR-CAB004A, 3TR-CAB036 Menyalurkan daya listrik DC ke motor.

Control Circuit Fuse End Cap Corrosion Sulphidation Due to Flue Gas Terbentuk lapisan film hitam pekat yang menghambat aliran arus listrik. Tahanan kontak menjadi sangat tinggi; Fuse sebenarnya elemennya bagus (tidak putus), tetapi listrik tidak mengalir karena tertutup lapisan sulfida. Teknisi sering salah diagnosa (mengira fuse putus); Gangguan intermiten Tutup fuse (yang aslinya perak mengkilap) berubah menjadi hitam legam atau biru tua; Saat fuse dilepas dan dipasang lagi (digesek), sistem normal kembali sesaat (karena lapisan film tergores), lalu bermasalah lagi kemudian; Ukur kontinuitas fuse dari ujung ke ujung cap. Multimeter mungkin menunjukkan nilai tahanan agak tinggi (bukan 0 Ohm murni) jika probe ditempelkan ringan tanpa ditekan kuat; Cek secara visual, warna hitam khas Silver Sulfide; Sistem HVAC ruang panel dengan tekanan positif (Positive Pressure); Filter kimia (Chemical Filter) pada intake udara ruangan; Jika lingkungan tinggi sulfur, hindari Silver Plated Fuse.

Bandingkan waktu trip dengan kurva pabrikan. Jika trip jauh lebih cepat (misal: harusnya 2 jam jadi 10 menit), bimetal sudah fatigue; Class Selection (Class 10, 20, 30) sesuai aplikasi motor; Indikator trip mekanis pada unit; Bimetal yang sudah mengalami deformasi permanen TIDAK BISA diperbaiki atau dikalibrasi ulang. Unit harus diganti baru; Cek apakah operator sering melakukan inching/jogging?

Thermal Overload Relay NC Contact High Resistance Oxide/Sulfide Film Buildup Kontak memiliki impedansi tinggi. Terjadi Voltage Drop di titik kontak 95-96; Arus kontrol tidak mampu menembus lapisan film isolator (low wetting current), sehingga koil kontaktor tidak mendapat tegangan cukup untuk pick-up sehingga fail to start; Motor mati sendiri secara acak karena tegangan koil jatuh di bawah batas drop-out saat resistansi kontak fluktuatif; Motor tidak mau start, tapi tidak ada indikasi trip pada TOR (tombol reset tidak menyembul); Tegangan terukur normal (110V DC) sebelum kontak NC, tapi drop atau 0V sesudah kontak NC saat tombol start ditekan; Saat rangkaian kontrol aktif (tombol start ditekan), ukur tegangan across terminal 95 dan 96. Harusnya mendekati 0V. Jika terukur beda potensial (misal >1V), berarti ada resistansi tinggi; Matikan panel. Ukur resistansi terminal 95-96. Nilai normal < 0; 1 ohm. Jika > 1 ohm atau pembacaan multimeter melompat-lompat, kontak kotor; Material kontak Silver-Nickel atau Gold-Flashed (pada tipe high-end); Pemanas panel (Heater); Tekan tombol "Test" atau "Stop" pada TOR beberapa kali secara manual. Gesekan mekanis (wiping action) seringkali cukup untuk merontokkan lapisan film oksida; Semprotkan cairan pembersih kontak (deoxidizer), lalu operasikan kontak.

Local/Remote Selector Switch (Changeover Switch) Contact Oxidation Low Wetting Current Secara fisik kontak menutup, tapi secara elektrikal sirkuit terbuka karena tegangan 24V tidak mampu "melompati" lapisan oksida; DCS mendeteksi posisi saklar sebagai "Local" padahal saklar ada di "Remote" (karena sinyal Remote hilang/terputus oleh oksida), sehingga DCS memblokir perintah start dari CCR; Operator memutar saklar ke Remote, tapi indikator di layar DCS tetap menunjukkan status "Not Ready" atau "Local Mode"; Masalah hilang sementara jika saklar diputar cepat atau diketuk (karena lapisan oksida tergores sedikit); Jangan gunakan Multimeter biasa mode Buzzer/Ohm untuk mengetes ini, karena baterai multimeter (9V/arus tinggi) bisa menembus oksida dan memberi hasil "Bagus" palsu; Gunakan multimeter mode voltase. Ukur tegangan across kontak saat sistem aktif. Jika ada tegangan 24V tertahan di saklar (padahal posisi closed), berarti kontak gagal konduksi arus rendah; Spesifikasi material kontak (AgNi atau Gold Plated); Untuk sinyal DCS/PLC (tegangan rendah/arus kecil), JANGAN gunakan contact block standar (Silver alloy). Gunakan contact block dengan Lapisan Emas (Gold Plated) atau kontak model Sliding/Wiping agresif. Emas tidak beroksidasi sehingga tidak butuh arus besar untuk wetting; Jika tidak ada kontak emas, pasang resistor dummy load paralel di input DCS untuk menarik arus lebih besar (misal >50mA) agar lapisan oksida bisa ditembus (wetting tercapai); +K3 & LH (KLH), Air Flue Gas (AFG), Boiler (BOL), Sis Pemakaian Sendiri (SPS), Ash Handling (ASH), Coal Handling (CH), Chlorination (CP), Water Treatment Plant (WTP), Generator (GEN), FGD Support (SUP), Screen & Filter (SCR) DC Motor Starter Panel DC Motor Starter Panel 3ABS-PAN861, 3AF-M501A, 3AH-PAN571A, 3AI-PAN501A, 3AI-PAN501B, 3AI-PAN501C, 3AL-M501A, 3AL-M501B, 3APC-MCC502A, 3APC-PD501A, 3APC-PD502, 3APC-PD891, 3APC-PD894, 3APC-PD901, 3APC-PD910, 3APC-PD921, 3APC-PD951, 3BAD-PAN501, 3BAD-PAN503, 3BAD-PAN504, 00CHA-PAN801A, 00CHA-PAN814, 00CHA-PAN824, 00CHA-PAN848, 00CHA-PAN854, 00CHA-PAN858, 00CHB-PAN805A, 00CL-PAN001, 00DMW-CAB100, 00DMW-CAB105A, 3EG-PAN002, 3EVM-PAN801, 3GEN-CAB002A, 3GEN-EXC006, 3GEN-CAB003A, 3GEN-CAB007A, 3GG-T801A, 4GG-T801A, 3GG-DAX501, 3H2-LP002, 00LSH-PAN801, 00LSH-PAN802, 00LSH-PAN803, 00LSH-PAN804, 00LSH-PAN862, 00LSH-PAN863, 00LSH-PAN865, 00LSH-PAN866, 00RO-CAB200, 00RO-CAB205, 00RO-CAB225A, 00RO-CAB245A, 00RO-CAB255A, 00RO-CAB275, 00RO-CAB280, 00RO-CAB285, 3SCR-PAN001, 3SCR-PAN002A, 00SSB-EV011, 3TR-CAB004A, 3TR-CAB091 Menjalankan motor saat diperintah Start.

Thermal Overload Relay NC Contact High Impedance Low Contact Pressure Kontak menjadi sensitif terhadap getaran. Resistansi kontak berfluktuasi; egangan yang melewati kontak NC drop signifikan (misal: masuk 110V, keluar tinggal 70V).

Ukur tegangan antara terminal 95 dan 96. Jika kontak bagus, harusnya ~0V. Jika terukur beda potensial besar (misal >5V), tekanan kontak lemah; Saat tombol start ditekan dan motor diam, ketuk body TOR dengan gagang obeng. Jika motor tiba-tiba menyala, itu konfirmasi tekanan kontak lemah; Uji Durabilitas Mekanis Pabrikan; Pegas internal yang lemah tidak dapat diperbaiki atau dikencangkan ulang karena berada dalam sealed unit.

Control Circuit Fuse Mechanical Jamming Coal Dust Cementation Mekanisme trip macet (Stuck Closed). Kontak NC (95-96) tidak terbuka meskipun bimetal sudah melengkung maksimal; Saat terjadi beban lebih (overload) atau rotor macet (locked rotor), TOR tidak memutus arus. Kumparan motor DC menerima arus tinggi terus-menerus hingga isolasinya terbakar; Panas ekstrem dari motor atau kabel bisa memicu kebakaran di area lokal. Sangat sulit dideteksi saat operasi normal; Tombol "Test/Stop" pada TOR terasa keras, macet, atau berpasir (gritty) saat ditekan teknisi; Tumpukan debu tebal terlihat di bagian luar relay. Dalam kondisi off, tekan tuas/tombol "Test". Jika tuas macet atau kontak NC tidak berubah status (cek dengan Ohmmeter), berarti mekanisme macet; Intip melalui celah ventilasi TOR, terlihat gumpalan hitam.

Control Circuit Fuse Mechanical Jamming Corrosion on Pivot Points Tuas trip "terkunci" oleh karat (seized); TOR gagal trip saat overload; Meskipun berhasil trip sekali (karena dipaksa gaya besar), ia mungkin tidak bisa di-reset atau macet lagi di kemudian hari. Terminal baut luar terlihat berkarat parah (indikasi kondisi internal serupa); Tombol Reset macet dan tidak mau kembali (spring back) setelah ditekan. Saat ditekan manual, gerakan tuas terasa kasar/seret, tidak "snappy" (cekat-ceket); Bongkar unit bekas. Cek apakah ada serbuk karat merah di mekanisme dalam. Material anti-korosi (Zinc plated steel parts); Pemanas Panel (Space Heater) untuk kontrol kelembaban. Untuk lingkungan korosif parah, jangan menunggu rusak. Ganti TOR setiap 5-8 tahun; Pastikan pemanas panel bekerja. Karat internal adalah tanda pasti bahwa panel terlalu lembab; Pertimbangkan upgrade ke Electronic Overload Relay (EOCR) yang komponennya di-potting (dicor resin) atau tertutup rapat, sehingga kebal terhadap korosi mekanis. +K3 & LH (KLH), Air Flue Gas (AFG), Boiler (BOL), Sis Pemakaian Sendiri (SPS), Ash Handling (ASH), Coal Handling (CH), Chlorination (CP), Water Treatment Plant (WTP), Generator (GEN), FGD Support (SUP), Screen & Filter (SCR) DC Motor Starter Panel DC Motor Starter Panel 3ABS-PAN861, 3AF-M501A, 3AH-PAN571A, 3AI-PAN501A, 3AI-PAN501B, 3AI-PAN501C, 3AL-M501A, 3AL-M501B, 3APC-MCC502A, 3APC-PD501A, 3APC-PD502, 3APC-PD891, 3APC-PD894, 3APC-PD901, 3APC-PD910, 3APC-PD921, 3APC-PD951, 3BAD-PAN501, 3BAD-PAN503, 3BAD-PAN504, 00CHA-PAN801A, 00CHA-PAN814, 00CHA-PAN824, 00CHA-PAN848, 00CHA-PAN854, 00CHA-PAN858, 00CHB-PAN805A, 00CL-PAN001, 00DMW-CAB100, 00DMW-CAB105A, 3EG-PAN002, 3EVM-PAN801, 3GEN-CAB002A, 3GEN-EXC006, 3GEN-CAB003A, 3GEN-CAB007A, 3GG-T801A, 4GG-T801A, 3GG-DAX501, 3H2-LP002, 00LSH-PAN801, 00LSH-PAN802, 00LSH-PAN803, 00LSH-PAN804, 00LSH-PAN862, 00LSH-PAN863, 00LSH-PAN865, 00LSH-PAN866, 00RO-CAB200, 00RO-CAB205, 00RO-CAB225A, 00RO-CAB245A, 00RO-CAB255A, 00RO-CAB275, 00RO-CAB280, 00RO-CAB285, 3SCR-PAN001, 3SCR-PAN002A, 00SSB-EV011, 3TR-CAB004A, 3TR-CAB114 Mengamankan motor saat terjadi gangguan (Overload/Short).

Control Circuit Fuse Heater Element Bypass Loose Heater Connection Terjadi arcing di titik koneksi yang longgar; Panas akibat arcing melelehkan plastik sekitarnya dan membentuk jalur karbon (charred path). Arus listrik kemudian mengalir melalui jalur karbon ini (bypass) daripada melalui elemen pemanas resistif; Panas timbul di titik baut yang longgar, bukan di sepanjang elemen bimetal. Bimetal tidak merasakan distribusi panas yang benar untuk memicu mekanisme trip. TOR trip tidak konsisten (kadang trip, kadang tidak); Terminal input/output terlihat gosong atau berubah warna parah; Plastik di sekitar baut heater meleleh. (Hanya untuk tipe interchangeable heater) Cek kekencangan baut pengikat elemen heater; Lihat apakah ada tanda leleh lokal yang ekstrem di satu titik koneksi saja. Desain Fixed Element pada TOR modern (menghilangkan risiko baut longgar). Hindari penggunaan TOR model lama dengan heater yang bisa dilepas-pasang (interchangeable) di area getaran tinggi, karena bautnya rawan kendor.

Namun, bimetal TOR bereaksi lambat karena terhalang selimut debu; Isolasi motor keburu terbakar sebelum bimetal cukup panas untuk melengkung dan memicu trip. Bentuk fisik TOR tidak terlihat jelas karena tertutup gumpalan debu hitam; Suhu casing TOR sangat panas, tapi tidak trip. Ketebalan debu > 1-2mm pada unit; Lakukan injeksi arus 300%. Bandingkan waktu trip dengan kurva. Unit yang kotor parah biasanya trip lebih lambat dari standar pabrik (Sluggish response). IP Rating Panel; Filter Udara. Bersihkan debu secara rutin menggunakan vakum khusus; Perbaiki karet pintu dan tutup lubang kabel (gland) agar debu batubara tidak masuk.

Control Circuit Fuse Broken Return Spring Heat Conducted Annealing Pegas menyusut/memendek. Tekanan balik menjadi sangat lemah; Kontak membuka sangat lambat saat stop, memicu busur api besar yang merusak kontak; Karena tekanan pembukaan lemah, jika ada sedikit saja micro-weld pada kontak, pegas tidak kuat memisahkannya. Kontaktor jadi macet total. Kontaktor terasa sangat panas di bagian body mekanisnya; Gerakan kontaktor saat membuka terlihat lambat/lemas; Pegas terlihat berubah warna menjadi biru/hitam (gosong). Bongkar sedikit casing atas. Lihat fisik pegas. Jika terlihat penyok atau memendek dibanding standar, pegas sudah annealed. Thermography rutin. Pegas yang melunak adalah gejala, bukan akar masalah. Cari sumber panasnya (Terminal kendor? Koil short? Beban overload?) dan perbaiki itu dulu; Sifat baja pegas yang sudah annealed tidak bisa dikembalikan.

Control Circuit Fuse Broken Return Spring High Cycle Fatigue Patah lelah (fatigue fracture), biasanya tegak lurus sumbu kawat pegas; Kontaktor berfungsi normal pagi harinya, lalu tiba-tiba macet siang harinya; Pecahan pegas bisa mengganjal mekanisme di posisi "setengah menutup", menyebabkan arcing parah dan kebakaran kontak. Umur pakai kontaktor sudah sangat lama (> 5-10 tahun atau jutaan operasi); Sering dilakukan inching (start-stop cepat) oleh operator. Lihat permukaan patahan pegas dengan kaca pembesar. Patahan akibat fatigue biasanya memiliki pola garis-garis pantai (beach marks) yang khas. Spesifikasi Mechanical Durability; Operations Counter pada DCS. Monitor jumlah operasi kontaktor via DCS. Lakukan penggantian proaktif jika sudah mencapai 80% dari Mechanical Life pabrikan (jangan tunggu rusak); Untuk aplikasi inching/jogging tinggi, gunakan kontaktor spesifikasi AC-4 / DC-5 yang memiliki pegas dan kontak lebih kuat dibanding tipe standar. +K3 & LH (KLH), Air Flue Gas (AFG), Boiler (BOL), Sis Pemakaian Sendiri (SPS), Ash Handling (ASH), Coal Handling (CH), Chlorination (CP), Water Treatment Plant (WTP), Generator (GEN), FGD Support (SUP), Screen & Filter (SCR) DC Motor Starter Panel DC Motor Starter Panel 3ABS-PAN861, 3AF-M501A, 3AH-PAN571A, 3AI-PAN501A, 3AI-PAN501B, 3AI-PAN501C, 3AL-M501A, 3AL-M501B, 3APC-MCC502A, 3APC-PD501A, 3APC-PD502, 3APC-PD891, 3APC-PD894, 3APC-PD901, 3APC-PD910, 3APC-PD921, 3APC-PD951, 3BAD-PAN501, 3BAD-PAN503, 3BAD-PAN504, 00CHA-PAN801A, 00CHA-PAN814, 00CHA-PAN824, 00CHA-PAN848, 00CHA-PAN854, 00CHA-PAN858, 00CHB-PAN805A, 00CL-PAN001, 00DMW-CAB100, 00DMW-CAB105A, 3EG-PAN002, 3EVM-PAN801, 3GEN-CAB002A, 3GEN-EXC006, 3GEN-CAB003A, 3GEN-CAB007A, 3GG-T801A, 4GG-T801A, 3GG-DAX501, 3H2-LP002, 00LSH-PAN801, 00LSH-PAN802, 00LSH-PAN803, 00LSH-PAN804, 00LSH-PAN862, 00LSH-PAN863, 00LSH-PAN865, 00LSH-PAN866, 00RO-CAB200, 00RO-CAB205, 00RO-CAB225A, 00RO-CAB245A, 00RO-CAB255A, 00RO-CAB275, 00RO-CAB280, 00RO-CAB285, 3SCR-PAN001, 3SCR-PAN002A, 00SSB-EV011, 3TR-CAB004A, 3TR-CAB130 Mengamankan motor saat terjadi gangguan (Overload/Short).

Molded Case Circuit Breaker (MCCB) Trip Curve Shift (Sluggish) Friction from Dust-Grease Sludge Gerakan mekanis trip terhambat. Dibutuhkan gaya (bimetal deflection) yang lebih besar atau waktu yang lebih lama untuk memicu mekanisme trip; Saat terjadi Overload, MCCB trip terlambat; Selama keterlambatan tersebut, kumparan motor terpanggang suhu tinggi. Isolasi motor degradasi atau terbakar total (burnout). Tuas (handle) MCCB terasa berat atau kesat saat dioperasikan manual (ON/OFF); Saat ditekan tombol "Push to Trip" (tes mekanis), tuas tidak langsung jatuh ke posisi Trip, atau jatuh dengan lambat/malas. Lakukan injeksi arus uji. Bandingkan waktu trip aktual dengan Time-Current Curve (TCC) pabrikan. Jika waktu trip melenceng jauh (lebih lama) di area batas toleransi atas, gesekan mekanis adalah penyebab umum; Rasa "lengket" saat tombol trip ditekan. Dust Cover internal (pada beberapa tipe); Jadwal Preventive Maintenance. Lakukan siklus ON-TRIP-RESET-ON minimal setahun sekali (saat shutdown) untuk mencegah mekanisme macet (stiffening); MCCB adalah unit tertutup (sealed unit). Jika mekanisme internal sudah macet oleh lumpur, tidak bisa dibongkar untuk dibersihkan. Ganti unit baru; Jangan menyemprotkan WD-40 atau pelumas cair ke dalam sela-sela tuas MCCB, karena akan menarik lebih banyak debu dan memperparah kemacetan nanti. +K3 & LH (KLH), Air Flue Gas (AFG), Boiler (BOL), Sis Pemakaian Sendiri (SPS), Ash Handling (ASH), Coal Handling (CH), Chlorination (CP), Water Treatment Plant (WTP), Generator (GEN), FGD Support (SUP), Screen & Filter (SCR) DC Motor Starter Panel DC Motor Starter Panel 3ABS-PAN861, 3AF-M501A, 3AH-PAN571A, 3AI-PAN501A, 3AI-PAN501B, 3AI-PAN501C, 3AL-M501A, 3AL-M501B, 3APC-MCC502A, 3APC-PD501A, 3APC-PD502, 3APC-PD891, 3APC-PD894, 3APC-PD901, 3APC-PD910, 3APC-PD921, 3APC-PD951, 3BAD-PAN501, 3BAD-PAN503, 3BAD-PAN504, 00CHA-PAN801A, 00CHA-PAN814, 00CHA-PAN824, 00CHA-PAN848, 00CHA-PAN854, 00CHA-PAN858, 00CHB-PAN805A, 00CL-PAN001, 00DMW-CAB100, 00DMW-CAB105A, 3EG-PAN002, 3EVM-PAN801, 3GEN-CAB002A, 3GEN-EXC006, 3GEN-CAB003A, 3GEN-CAB007A, 3GG-T801A, 4GG-T801A, 3GG-DAX501, 3H2-LP002, 00LSH-PAN801, 00LSH-PAN802, 00LSH-PAN803, 00LSH-PAN804, 00LSH-PAN862, 00LSH-PAN863, 00LSH-PAN865, 00LSH-PAN866, 00RO-CAB200, 00RO-CAB205, 00RO-CAB225A, 00RO-CAB245A, 00RO-CAB255A, 00RO-CAB275, 00RO-CAB280, 00RO-CAB285, 3SCR-PAN001, 3SCR-PAN002A, 00SSB-EV011, 3TR-CAB004A, 3TR-CAB131 Mengamankan motor saat terjadi gangguan (Overload/Short).

Jika waktu trip jauh lebih lama dari kurva standar, kalibrasi termal telah bergeser. (Note: Tes magnetik biasanya tetap normal, hanya tes termal yang gagal). Thread-locking compound (Loctite merah) pada sekrup kalibrasi pabrik. Lakukan uji injeksi rutin setiap 3-5 tahun (sesuai standar NETA/IEC); Jangan mencoba memutar ulang sekrup kalibrasi yang segelnya rusak di lapangan tanpa peralatan kalibrasi presisi.

Terapkan kebijakan penggantian berbasis waktu/kondisi. Jika MCCB kritis sudah berusia >20 tahun, rencanakan penggantian (retrofit) meskipun "masih bisa ON/OFF", karena akurasi proteksinya diragukan; Cek suhu body MCCB.

Terdengar suara "klotak-klotak" (benda jatuh) di dalam panel; Saat pintu dibuka, tutup duct terlihat jatuh di dasar panel; Kabel terlihat menggantung tidak rapi dan terjepit di engsel pintu. Buka panel. Cek apakah semua tutup duct terpasang rapat; Periksa fisik kabel yang keluar jalur. Apakah ada bekas gesekan/sayatan? Desain kuncian Snap-on pada duct. Jangan hanya mengandalkan tutup duct. Ikat kabel di dalam duct menggunakan Cable Ties setiap jarak 20-30cm. Jadi meskipun tutup duct lepas karena getaran, kabel tetap rapi di tempatnya dan tidak tumpah keluar; Jika kigi kuncian duct sudah aus/dol, ganti duct baru. Jangan diisolasi ban (lakban) dari luar karena lemnya akan meleleh kena panas dan lepas lagi. +K3 & LH (KLH), Air Flue Gas (AFG), Boiler (BOL), Sis Pemakaian Sendiri (SPS), Ash Handling (ASH), Coal Handling (CH), Chlorination (CP), Water Treatment Plant (WTP), Generator (GEN), FGD Support (SUP), Screen & Filter (SCR) DC Motor Starter Panel DC Motor Starter Panel 3ABS-PAN861, 3AF-M501A, 3AH-PAN571A, 3AI-PAN501A, 3AI-PAN501B, 3AI-PAN501C, 3AL-M501A, 3AL-M501B, 3APC-MCC502A, 3APC-PD501A, 3APC-PD502, 3APC-PD891, 3APC-PD894, 3APC-PD901, 3APC-PD910, 3APC-PD921, 3APC-PD951, 3BAD-PAN501, 3BAD-PAN503, 3BAD-PAN504, 00CHA-PAN801A, 00CHA-PAN814, 00CHA-PAN824, 00CHA-PAN848, 00CHA-PAN854, 00CHA-PAN858, 00CHB-PAN805A, 00CL-PAN001, 00DMW-CAB100, 00DMW-CAB105A, 3EG-PAN002, 3EVM-PAN801, 3GEN-CAB002A, 3GEN-EXC006, 3GEN-CAB003A, 3GEN-CAB007A, 3GG-T801A, 4GG-T801A, 3GG-DAX501, 3H2-LP002, 00LSH-PAN801, 00LSH-PAN802, 00LSH-PAN803, 00LSH-PAN804, 00LSH-PAN862, 00LSH-PAN863, 00LSH-PAN865, 00LSH-PAN866, 00RO-CAB200, 00RO-CAB205, 00RO-CAB225A, 00RO-CAB245A, 00RO-CAB255A, 00RO-CAB275, 00RO-CAB280, 00RO-CAB285, 3SCR-PAN001, 3SCR-PAN002A, 00SSB-EV011, 3TR-CAB004A, 3TR-CAB142 Mengamankan motor saat terjadi gangguan (Overload/Short).

Control Wiring & Terminal (Protective Loop) Vibration Induced Short Unsecured Components (Floating Components) Kaki komponen patah akibat kelelahan logam (fatigue). Terjadi percikan api saat komponen yang "telanjang" menyentuh backplate panel; Bayangkan sebuah resistor dummy load dipasang melayang paralel dengan kontak TOR. Jika resistor ini short (karena kakinya bengkok kena guncangan), maka TOR ter-bypass.

Auxiliary Contact Block High Contact Resistance Low Wetting Current Kontak tertutup secara mekanis, tetapi terisolasi secara elektrikal (Open Circuit) bagi sinyal lemah; Motor berjalan (Run), tapi DCS membaca status "Stop"; Saat operator menekan tombol Start, motor menyala, tetapi karena sinyal "Run Feedback" tidak diterima DCS dalam waktu tertentu (misal 5 detik), DCS menganggap start gagal dan mengirim perintah Trip (Mismatch Trip). Status motor di layar DCS berkedip (flickering) atau menunjukkan tanda silang/tanya (Bad Quality); Alarm "Discrepancy" atau "Fail to Start" muncul sesaat setelah start, padahal motor terdengar jalan. Saat kontak tertutup, ukur tegangan across terminal kontak. Jika terbaca ada beda potensial (misal 10-24V) padahal kontak Closed, berarti resistansi tinggi menghambat sinyal. Penggunaan modul I/O dengan arus injeksi standar. Ganti blok kontak standar (Silver Alloy) dengan tipe Gold-Plated (Emas) atau Bifurcated (Twin) Contact. Emas tidak beroksidasi dan sangat handal untuk sinyal arus rendah (low energy logic); Jika penggantian kontak sulit, pasang resistor beban (dummy load) paralel dengan input DCS untuk menarik arus lebih besar (misal >10mA) agar lapisan oksida tertembus (punch-through). +K3 & LH (KLH), Air Flue Gas (AFG), Boiler (BOL), Sis Pemakaian Sendiri (SPS), Ash Handling (ASH), Coal Handling (CH), Chlorination (CP), Water Treatment Plant (WTP), Generator (GEN), FGD Support (SUP), Screen & Filter (SCR) DC Motor Starter Panel DC Motor Starter Panel 3ABS-PAN861, 3AF-M501A, 3AH-PAN571A, 3AI-PAN501A, 3AI-PAN501B, 3AI-PAN501C, 3AL-M501A, 3AL-M501B, 3APC-MCC502A, 3APC-PD501A, 3APC-PD502, 3APC-PD891, 3APC-PD894, 3APC-PD901, 3APC-PD910, 3APC-PD921, 3APC-PD951, 3BAD-PAN501, 3BAD-PAN503, 3BAD-PAN504, 00CHA-PAN801A, 00CHA-PAN814, 00CHA-PAN824, 00CHA-PAN848, 00CHA-PAN854, 00CHA-PAN858, 00CHB-PAN805A, 00CL-PAN001, 00DMW-CAB100, 00DMW-CAB105A, 3EG-PAN002, 3EVM-PAN801, 3GEN-CAB002A, 3GEN-EXC006, 3GEN-CAB003A, 3GEN-CAB007A, 3GG-T801A, 4GG-T801A, 3GG-DAX501, 3H2-LP002, 00LSH-PAN801, 00LSH-PAN802, 00LSH-PAN803, 00LSH-PAN804, 00LSH-PAN862, 00LSH-PAN863, 00LSH-PAN865, 00LSH-PAN866, 00RO-CAB200, 00RO-CAB205, 00RO-CAB225A, 00RO-CAB245A, 00RO-CAB255A, 00RO-CAB275, 00RO-CAB280, 00RO-CAB285, 3SCR-PAN001, 3SCR-PAN002A, 00SSB-EV011, 3TR-CAB004A, 3TR-CAB144 Memberikan data status yang benar ke DCS.

Auxiliary Contact Block High Contact Resistance Dormant Operation Debu/oksida menumpuk di celah kontak; Saat motor akhirnya perlu beroperasi (misal saat blackout), kontak bantu gagal mengirim sinyal "Run" karena tertutup debu. DCS mungkin mematikan pompa kembali karena dianggap gagal start, padahal pompa tersebut sangat kritis saat itu. Tidak ada indikasi sampai peralatan dioperasikan; Status di DCS tidak berubah (Stuck) saat dilakukan tes rutin. Operasikan kontak beberapa kali (On-Off). Jika resistansi tiba-tiba turun menjadi normal setelah 3-5 kali operasi, masalahnya adalah akumulasi pasif (dormancy). Jadwal Routine Test / Change-over mingguan.

Auxiliary Contact Block Mechanical Mounting Loose Snap-fit Fatigue Blok kontak bergeser mundur atau miring dari posisinya. Plunger (tuas pendorong) kontak bantu tidak lagi ditekan penuh oleh armature kontaktor utama; Kontaktor utama menutup (Motor Jalan), tetapi karena blok kontak bantu bergeser, tuasnya tidak tertekan.

Auxiliary Contact Block Contact Bounce / Chatter Weak Internal Spring Terjadi micro-arcing setiap kali kontak memantul, mempercepat kerusakan permukaan kontak; DCS mendeteksi perubahan status berulang-ulang dalam waktu singkat; Jika DCS memiliki timer penghitung jam operasi (Running Hours) yang sensitif, sinyal bounce ini bisa mereset penghitung atau memicu alarm palsu "Motor Stop" hanya milidetik setelah Start. Lampu indikator di panel lokal berkedip sesaat saat start; Sequence of Events (SOE) log di DCS menunjukkan banyak entri status "Run/Stop" dalam hitungan milidetik. Sambungkan probe ke terminal kontak bantu. Rekam gelombang tegangan saat switching. Jika terlihat banyak "noise" atau putus-nyambung sebelum sinyal stabil, itu adalah bounce; Tekan plunger kontak bantu secara manual (saat dilepas). Jika terasa lembek/ringan, pegas lemah. DCS Debounce Timer (Filter software untuk mengabaikan sinyal transien < 50ms). Pegas internal kontak bantu tidak dapat diganti. Ganti satu blok kontak baru; Cek setting Debounce Time pada Digital Input Card DCS. Standar biasanya 50ms-100ms. Jika diset 0ms (terlalu sensitif), naikkan sedikit untuk memfilter bounce akibat penuaan pegas sementara waktu sebelum penggantian part. +K3 & LH (KLH), Air Flue Gas (AFG), Boiler (BOL), Sis Pemakaian Sendiri (SPS), Ash Handling (ASH), Coal Handling (CH), Chlorination (CP), Water Treatment Plant (WTP), Generator (GEN), FGD Support (SUP), Screen & Filter (SCR) DC Motor Starter Panel DC Motor Starter Panel 3ABS-PAN861, 3AF-M501A, 3AH-PAN571A, 3AI-PAN501A, 3AI-PAN501B, 3AI-PAN501C, 3AL-M501A, 3AL-M501B, 3APC-MCC502A, 3APC-PD501A, 3APC-PD502, 3APC-PD891, 3APC-PD894, 3APC-PD901, 3APC-PD910, 3APC-PD921, 3APC-PD951, 3BAD-PAN501, 3BAD-PAN503, 3BAD-PAN504, 00CHA-PAN801A, 00CHA-PAN814, 00CHA-PAN824, 00CHA-PAN848, 00CHA-PAN854, 00CHA-PAN858, 00CHB-PAN805A, 00CL-PAN001, 00DMW-CAB100, 00DMW-CAB105A, 3EG-PAN002, 3EVM-PAN801, 3GEN-CAB002A, 3GEN-EXC006, 3GEN-CAB003A, 3GEN-CAB007A, 3GG-T801A, 4GG-T801A, 3GG-DAX501, 3H2-LP002, 00LSH-PAN801, 00LSH-PAN802, 00LSH-PAN803, 00LSH-PAN804, 00LSH-PAN862, 00LSH-PAN863, 00LSH-PAN865, 00LSH-PAN866, 00RO-CAB200, 00RO-CAB205, 00RO-CAB225A, 00RO-CAB245A, 00RO-CAB255A, 00RO-CAB275, 00RO-CAB280, 00RO-CAB285, 3SCR-PAN001, 3SCR-PAN002A, 00SSB-EV011, 3TR-CAB004A, 3TR-CAB150 Memberikan data status yang benar ke DCS.

Auxiliary Contact Block Contact Bounce / Chatter Uneven Wear (Pitting) Resistansi kontak berfluktuasi tinggi; Sinyal analog atau digital menjadi "kotor"; Alarm status muncul dan hilang secara acak saat ada sedikit getaran pada panel, karena kontak yang kasar sangat sensitif terhadap gerakan. Status motor di DCS "Flickering" (Hijau-Merah bergantian cepat); Tidak ada pola yang jelas (random). Lihat permukaan kontak (jika bisa dibuka/transparan). permukaan yang sehat harus mulus. permukaan pitted terlihat seperti kawah bulan; Ukur Ohm saat kontak Closed. Ketuk perlahan. Jika nilai Ohm melompat drastis, kontak sudah bopeng parah. Preventive Maintenance (Cleaning). Jangan mengikir/mengamplas kontak bantu yang bopeng. Lapisan plating (perak/emas) sangat tipis.

Control Relay / Interposing Relay Coil Burnout Sustained Overvoltage (Float Charging Issue) Kawat tembaga koil putus (Open Circuit). Relay kembali ke posisi normal (De-energized); Jika relay ini berfungsi mengirim status "Running" ke DCS. Saat motor sedang jalan, koil relay terbakar dan kontak terbuka. DCS menerima sinyal "0" dan menampilkan status "STOP", padahal motor di lapangan masih berputar kencang. Ini menyesatkan operator; DCS mendeteksi ketidaksesuaian antara perintah (Start) dan feedback (Status Off), memicu alarm Discrepancy. Body relay terasa sangat panas saat disentuh; Plastik pembungkus relay terlihat berubah warna (kekuningan/coklat). Cabut relay. Ukur resistansi kaki koil (biasanya pin 13-14 atau A1-A2). Jika (Infinite/OL), koil putus; Cek tegangan DC Bus saat mode charging. Spesifikasi toleransi tegangan relay; Proteksi Overvoltage pada DC Charger. Gunakan relay interposing spesifikasi khusus DC Wide Voltage Range (misal: bekerja dari 80% s.d. 130% Un). Relay murah/standar AC yang dipakai di DC seringkali tidak tahan float voltage; Pastikan mode Equalizing Charge (tegangan tinggi) pada charger memiliki timer otomatis dan tidak menyala terus-menerus. +K3 & LH (KLH), Air Flue Gas (AFG), Boiler (BOL), Sis Pemakaian Sendiri (SPS), Ash Handling (ASH), Coal Handling (CH), Chlorination (CP), Water Treatment Plant (WTP), Generator (GEN), FGD Support (SUP), Screen & Filter (SCR) DC Motor Starter Panel DC Motor Starter Panel 3ABS-PAN861, 3AF-M501A, 3AH-PAN571A, 3AI-PAN501A, 3AI-PAN501B, 3AI-PAN501C, 3AL-M501A, 3AL-M501B, 3APC-MCC502A, 3APC-PD501A, 3APC-PD502, 3APC-PD891, 3APC-PD894, 3APC-PD901, 3APC-PD910, 3APC-PD921, 3APC-PD951, 3BAD-PAN501, 3BAD-PAN503, 3BAD-PAN504, 00CHA-PAN801A, 00CHA-PAN814, 00CHA-PAN824, 00CHA-PAN848, 00CHA-PAN854, 00CHA-PAN858, 00CHB-PAN805A, 00CL-PAN001, 00DMW-CAB100, 00DMW-CAB105A, 3EG-PAN002, 3EVM-PAN801, 3GEN-CAB002A, 3GEN-EXC006, 3GEN-CAB003A, 3GEN-CAB007A, 3GG-T801A, 4GG-T801A, 3GG-DAX501, 3H2-LP002, 00LSH-PAN801, 00LSH-PAN802, 00LSH-PAN803, 00LSH-PAN804, 00LSH-PAN862, 00LSH-PAN863, 00LSH-PAN865, 00LSH-PAN866, 00RO-CAB200, 00RO-CAB205, 00RO-CAB225A, 00RO-CAB245A, 00RO-CAB255A, 00RO-CAB275, 00RO-CAB280, 00RO-CAB285, 3SCR-PAN001, 3SCR-PAN002A, 00SSB-EV011, 3TR-CAB004A, 3TR-CAB153 Memberikan data status yang benar ke DCS.

Relay mati mendadak disertai bau ozon/gosong; Mungkin terdengar suara "pop" kecil saat koil putus. Ukur induktansi atau resistansi. Nilai resistansi yang jauh lebih rendah dari spek menandakan shorted turns sebelum akhirnya putus; Periksa apakah ada Flyback Diode terpasang di soket atau internal relay. Relay dengan indikator LED dan Dioda internal. Wajib memasang dioda (seperti 1N4007) secara reverse-bias paralel dengan koil relay, atau gunakan relay tipe "D" (With Diode) bawaan pabrik.

Hati-hati, suhu bisa >70 C. Ventilasi panel (Exhaust fan) Saat desain/pemasangan, berikan jarak (spacer) setidaknya 5-10mm antar blok relay, atau pasang secara selang-seling (staggered) jika memungkinkan, agar panas bisa terbuang; Jika suhu panel tinggi, pilih relay dengan rating suhu kerja yang lebih tinggi (Class F Insulation). +K3 & LH (KLH), Air Flue Gas (AFG), Boiler (BOL), Sis Pemakaian Sendiri (SPS), Ash Handling (ASH), Coal Handling (CH), Chlorination (CP), Water Treatment Plant (WTP), Generator (GEN), FGD Support (SUP), Screen & Filter (SCR) DC Motor Starter Panel DC Motor Starter Panel 3ABS-PAN861, 3AF-M501A, 3AH-PAN571A, 3AI-PAN501A, 3AI-PAN501B, 3AI-PAN501C, 3AL-M501A, 3AL-M501B, 3APC-MCC502A, 3APC-PD501A, 3APC-PD502, 3APC-PD891, 3APC-PD894, 3APC-PD901, 3APC-PD910, 3APC-PD921, 3APC-PD951, 3BAD-PAN501, 3BAD-PAN503, 3BAD-PAN504, 00CHA-PAN801A, 00CHA-PAN814, 00CHA-PAN824, 00CHA-PAN848, 00CHA-PAN854, 00CHA-PAN858, 00CHB-PAN805A, 00CL-PAN001, 00DMW-CAB100, 00DMW-CAB105A, 3EG-PAN002, 3EVM-PAN801, 3GEN-CAB002A, 3GEN-EXC006, 3GEN-CAB003A, 3GEN-CAB007A, 3GG-T801A, 4GG-T801A, 3GG-DAX501, 3H2-LP002, 00LSH-PAN801, 00LSH-PAN802, 00LSH-PAN803, 00LSH-PAN804, 00LSH-PAN862, 00LSH-PAN863, 00LSH-PAN865, 00LSH-PAN866, 00RO-CAB200, 00RO-CAB205, 00RO-CAB225A, 00RO-CAB245A, 00RO-CAB255A, 00RO-CAB275, 00RO-CAB280, 00RO-CAB285, 3SCR-PAN001, 3SCR-PAN002A, 00SSB-EV011, 3TR-CAB004A, 3TR-CAB155 Memberikan data status yang benar ke DCS.

Control Relay / Interposing Relay Socket Poor Connection Missing Retaining Clip Kaki pin relay tidak menancap penuh. Kontak menjadi intermiten saat ada getaran; Status motor di DCS berkedip-kedip (Flickering) mengikuti getaran mesin; Jika relay jatuh/lepas total, DCS kehilangan sinyal feedback sepenuhnya. Operator tidak tahu motor sedang jalan atau mati; Jika relay ini adalah bagian dari loop interlock (misal: Lube Oil Pressure OK), sinyal yang hilang sesaat akibat getaran bisa mentripkan turbin/motor utama secara tidak perlu. Relay terlihat miring atau renggang dari soketnya; Saat relay ditekan dengan jari, bunyi "klik" relay aktif terdengar lebih tegas atau status DCS tiba-tiba normal. Cek apakah klip terpasang; Tarik body relay perlahan. Jika mudah terlepas tanpa hambatan pengunci, berarti klip hilang atau tidak berfungsi. Aksesoris standar pabrikan (Clip) Sediakan stok Retaining Clip (tipe kawat logam lebih disarankan daripada plastik yang mudah patah); Pastikan setiap penggantian relay diakhiri dengan pemasangan klip sampai bunyi "Klik".

Control Relay / Interposing Relay Socket Poor Connection Plastic Creep on Socket Resistansi kontak antara pin dan soket meningkat. Timbul panas lokal yang justru memperparah pelelehan plastik; Sinyal 24VDC ke DCS mengalami drop tegangan di soket. Jika tegangan turun di bawah ambang batas Logic High (misal <15V), DCS membaca status "OFF" atau "Unknown", padahal kontak relay sebenarnya tertutup. Plastik di sekitar lubang pin soket berubah warna (kecoklatan/gosong); Relay terasa sangat "oblak" (longgar) saat dimasukkan, tidak ada tahanan gesek. Masukkan relay baru ke soket lama. Jika masuk terlalu mudah (tanpa gaya tekan), soket sudah afkir (rusak); Terdeteksi hotspot pada kaki relay. Material Flame Retardant. Kesalahan umum teknisi adalah hanya mengganti relay-nya.

Resistansi menjadi tinggi dan tidak stabil; Sinyal analog atau digital ke DCS terganggu noise; DCS menandai tag tersebut sebagai "Bad Quality" karena sinyal terputus-putus. Operator kehilangan kepercayaan pada indikasi panel. Sinyal kembali normal jika panel dipukul atau relay digoyangkan (karena lapisan oksida tergeser sesaat); Saat relay dicabut, kaki-kakinya terlihat kusam, hitam, atau ada serbuk gelap. Cabut relay. Periksa pin-nya. Pin yang sehat harus mengkilap; Bersihkan kaki relay dengan penghapus karet atau contact cleaner. Pasang lagi. Jika normal, konfirmasi masalah korosi permukaan. Gold Plated Socket (jarang dipakai di standar industri biasa). Gunakan soket dengan mekanisme penjepit ganda (dual-leaf spring) untuk cengkeraman lebih baik; Aplikasikan sedikit Conductive Grease atau Contact Lubricant pada kaki relay sebelum dipasang untuk mencegah oksidasi udara dan mengurangi keausan akibat fretting. +K3 & LH (KLH), Air Flue Gas (AFG), Boiler (BOL), Sis Pemakaian Sendiri (SPS), Ash Handling (ASH), Coal Handling (CH), Chlorination (CP), Water Treatment Plant (WTP), Generator (GEN), FGD Support (SUP), Screen & Filter (SCR) DC Motor Starter Panel DC Motor Starter Panel 3ABS-PAN861, 3AF-M501A, 3AH-PAN571A, 3AI-PAN501A, 3AI-PAN501B, 3AI-PAN501C, 3AL-M501A, 3AL-M501B, 3APC-MCC502A, 3APC-PD501A, 3APC-PD502, 3APC-PD891, 3APC-PD894, 3APC-PD901, 3APC-PD910, 3APC-PD921, 3APC-PD951, 3BAD-PAN501, 3BAD-PAN503, 3BAD-PAN504, 00CHA-PAN801A, 00CHA-PAN814, 00CHA-PAN824, 00CHA-PAN848, 00CHA-PAN854, 00CHA-PAN858, 00CHB-PAN805A, 00CL-PAN001, 00DMW-CAB100, 00DMW-CAB105A, 3EG-PAN002, 3EVM-PAN801, 3GEN-CAB002A, 3GEN-EXC006, 3GEN-CAB003A, 3GEN-CAB007A, 3GG-T801A, 4GG-T801A, 3GG-DAX501, 3H2-LP002, 00LSH-PAN801, 00LSH-PAN802, 00LSH-PAN803, 00LSH-PAN804, 00LSH-PAN862, 00LSH-PAN863, 00LSH-PAN865, 00LSH-PAN866, 00RO-CAB200, 00RO-CAB205, 00RO-CAB225A, 00RO-CAB245A, 00RO-CAB255A, 00RO-CAB275, 00RO-CAB280, 00RO-CAB285, 3SCR-PAN001, 3SCR-PAN002A, 00SSB-EV011, 3TR-CAB004A, 3TR-CAB158 Memberikan data status yang benar ke DCS.

Control Relay / Interposing Relay Contact Stuck Corrosion on Contacts (Fretting) Kontak relay tersangkut fisik di posisi tertutup (Latched by friction); Motor sudah dimatikan (Stop), tapi relay status tetap nyangkut. DCS menampilkan motor masih "Running"; Jika relay ini memberikan sinyal "Lube Oil Pump Running" sebagai syarat start Turbin, Turbin bisa di-start padahal pompa oli sebenarnya mati. Ini berpotensi merusak bearing Turbin. Status di DCS tidak berubah (Stuck) meskipun motor dimatikan; Jika relay diketuk jari (tap test), status tiba-tiba kembali normal (karena guncangan melepas kuncian mekanis). permukaan kontak terlihat sangat kasar, hitam, dan berlubang-lubang; Saat koil mati tapi kontak masih Closed (cek kontinuitas), ketuk relay. Jika langsung Open, itu adalah masalah mekanis/friksi. Enclosure tertutup (Relay cover). Masalah utamanya adalah getaran yang menyebabkan fretting. Pasang bantalan karet pada mounting panel; Kontak yang sudah kasar tidak bisa diperbaiki. Ganti relay baru; Gunakan relay dengan kontak kembar (twin/bifurcated).

Control Relay / Interposing Relay Contact Stuck Sticky Residue (Silicone/Oil Vapor) Gaya lengket (adhesion) residu lebih besar daripada gaya tarik pegas pengembalian. Kontak "terlem" di posisi tertutup; Kontak mungkin akhirnya terbuka setelah beberapa detik (lambat), menyebabkan delay pada pembacaan status; Pada kasus parah, kontak tidak mau terbuka sama sekali. DCS buta terhadap kondisi trip motor. Relay merespon lambat (sluggish); Terlihat lapisan film kuning/coklat transparan pada mekanisme kontak (jika casing bening). Cek lingkungan sekitar. Apakah ada penggunaan silikon sealant atau spray pelumas di dekat panel?; Bau kimia asing dari dalam relay saat dibuka. Larangan penggunaan silikon di area elektrikal. DILARANG KERAS menggunakan semprotan/sealant berbasis silikon di dalam panel kontrol. Silikon adalah musuh utama kontak relay (Silicone Poisoning); Bersihkan panel dari kabut minyak (oil mist).

Control Relay / Interposing Relay Contact Stuck Micro-Welding from Capacitive Load Kontak las titik (spot weld); Relay rusak permanen di posisi tertutup. DCS selamanya membaca status "1";Jika ini adalah sinyal status Safety Device (misal: Level Switch), DCS tidak akan pernah tahu kalau level sudah bahaya. Relay mati (koil tidak bertegangan), tapi kontak tetap nyambung (0 Ohm); Relay tidak bisa dilepas dari lengketnya walaupun diketuk (las permanen). Cek panjang kabel dari panel ke I/O room. Jika >50-100 meter tanpa proteksi, risiko kapasitif sangat tinggi; Ukur kontak saat relay dicabut. Rating arus kontak (biasanya relay 5A dipakai untuk beban mA, jadi dianggap aman, padahal inrush kapasitif bisa >10A sesaat). Kontak emas memiliki titik leleh berbeda dan resistansi kontak rendah, lebih tahan terhadap micro-welding pada beban rendah; Pasang resistor seri (misal 100 Ohm - 1 kOhm) pada jalur kabel ke DCS. Resistor ini akan membatasi arus inrush dari kapasitansi kabel (RC Time Constant) sehingga tidak merusak kontak.

Terminal Block & Internal Wiring Loose Terminal Screw Vibration-Induced Loosening (Back-out) Kabel sinyal menjadi longgar di dalam klem terminal. Terjadi kontak intermiten (putus-nyambung); Sinyal status di DCS berkedip-kedip atau berubah status secara acak (0-1-0-1) mengikuti pola getaran mesin; Modul I/O DCS mendeteksi perubahan resistansi loop yang drastis, menandai sinyal sebagai "Bad Quality" atau "Wire Break". Jika panel dipukul pelan atau pintu ditutup keras, status di DCS berubah atau berkedip; Baut terminal terlihat lebih tinggi dari tetangganya (jika longgar parah). Tarik pelan kabel sinyal satu per satu di terminal blok. Jika kabel ikut bergerak atau terlepas, baut longgar; Cek kekencangan dengan obeng. Jika bisa diputar dengan jari atau tanpa tenaga, berarti longgar Penggunaan Spring Washer (Ring Per); Jadwal kencangkan baut (Retorquing) tahunan. Untuk area vibrasi tinggi, ganti terminal blok tipe baut (screw type) dengan tipe Spring-Cage / Push-in (e.g., Wago/Phoenix Contact). Tipe pegas (spring) kebal terhadap getaran karena gaya jepitnya konstan dan tidak bergantung pada drat baut; Pastikan mounting panel memiliki karet peredam. +K3 & LH (KLH), Air Flue Gas (AFG), Boiler (BOL), Sis Pemakaian Sendiri (SPS), Ash Handling (ASH), Coal Handling (CH), Chlorination (CP), Water Treatment Plant (WTP), Generator (GEN), FGD Support (SUP), Screen & Filter (SCR) DC Motor Starter Panel DC Motor Starter Panel 3ABS-PAN861, 3AF-M501A, 3AH-PAN571A, 3AI-PAN501A, 3AI-PAN501B, 3AI-PAN501C, 3AL-M501A, 3AL-M501B, 3APC-MCC502A, 3APC-PD501A, 3APC-PD502, 3APC-PD891, 3APC-PD894, 3APC-PD901, 3APC-PD910, 3APC-PD921, 3APC-PD951, 3BAD-PAN501, 3BAD-PAN503, 3BAD-PAN504, 00CHA-PAN801A, 00CHA-PAN814, 00CHA-PAN824, 00CHA-PAN848, 00CHA-PAN854, 00CHA-PAN858, 00CHB-PAN805A, 00CL-PAN001, 00DMW-CAB100, 00DMW-CAB105A, 3EG-PAN002, 3EVM-PAN801, 3GEN-CAB002A, 3GEN-EXC006, 3GEN-CAB003A, 3GEN-CAB007A, 3GG-T801A, 4GG-T801A, 3GG-DAX501, 3H2-LP002, 00LSH-PAN801, 00LSH-PAN802, 00LSH-PAN803, 00LSH-PAN804, 00LSH-PAN862, 00LSH-PAN863, 00LSH-PAN865, 00LSH-PAN866, 00RO-CAB200, 00RO-CAB205, 00RO-CAB225A, 00RO-CAB245A, 00RO-CAB255A, 00RO-CAB275, 00RO-CAB280, 00RO-CAB285, 3SCR-PAN001, 3SCR-PAN002A, 00SSB-EV011, 3TR-CAB004A, 3TR-CAB162 Memberikan data status yang benar ke DCS.

Terminal Block & Internal Wiring Loose Terminal Screw Thermal Expansion/Contraction (Cold Flow) Oksidasi terbentuk di celah yang longgar, meningkatkan resistansi kontak; Karena arus sinyal kecil (mA), peningkatan resistansi menyebabkan tegangan sinyal drop; Tegangan 12V mungkin berada di area "Undefined" (abu-abu) bagi Digital Input DCS, sehingga status tidak terbaca atau dianggap "OFF" padahal kontak tertutup. Gangguan sering terjadi pada siklus suhu ekstrem (pagi hari yang dingin atau siang bolong); Baut terasa kencang saat dicek, tapi kabel di dalamnya gepeng dan longgar. Ukur tegangan across terminal saat sirkuit tertutup. Harus mendekati 0V; Lepas kabel. Ujung tembaga terlihat sangat pipih/gepeng dan kusam. Penggunaan Ferrule (Skun tusuk). WAJIB menggunakan Ferrule (Bootlace Ferrule) pada ujung kabel serabut. Ferrule menjaga bentuk kabel agar tidak menyebar dan memberikan bantalan terhadap tekanan baut, mencegah efek cold flow yang parah.

Terminal Block & Internal Wiring Wire Insulation Chafing (Short) Overfilled Cable Trunking Kompresi isolasi kabel (cold flow) hingga menipis, atau lecet akibat gesekan antar kabel; Kabel sinyal status (input) lecet dan bersentuhan dengan kabel perintah (output) atau kabel power lain di dalam duct yang sama; Tegangan dari kabel tetangga "bocor" masuk ke kabel status DCS. DCS membaca status "1" (Running) palsu akibat induksi atau kontak fisik ini, padahal motor mati. Tutup cable duct terlihat melengkung keluar atau sering lepas sendiri karena tekanan dari dalam; Sinyal DCS aneh (ghost signal) muncul di tag yang kabelnya berada satu jalur dengan kabel peralatan lain. Buka tutup duct. Jika kabel langsung "muncrat" keluar saat dibuka, berarti overfilled; Cari kabel yang gepeng atau ada bekas tekanan sudut duct. Standar Fill Ratio (maksimum 60% isi). Pindahkan sebagian kabel ke jalur lain atau pasang duct tambahan di luar jika memungkinkan. Jangan memaksakan duct penuh; Pisahkan kabel sinyal digital (24VDC) dengan kabel power/kontrol (110VDC) di duct yang berbeda untuk mencegah risiko short beda tegangan yang fatal bagi I/O Card DCS. +K3 & LH (KLH), Air Flue Gas (AFG), Boiler (BOL), Sis Pemakaian Sendiri (SPS), Ash Handling (ASH), Coal Handling (CH), Chlorination (CP), Water Treatment Plant (WTP), Generator (GEN), FGD Support (SUP), Screen & Filter (SCR) DC Motor Starter Panel DC Motor Starter Panel 3ABS-PAN861, 3AF-M501A, 3AH-PAN571A, 3AI-PAN501A, 3AI-PAN501B, 3AI-PAN501C, 3AL-M501A, 3AL-M501B, 3APC-MCC502A, 3APC-PD501A, 3APC-PD502, 3APC-PD891, 3APC-PD894, 3APC-PD901, 3APC-PD910, 3APC-PD921, 3APC-PD951, 3BAD-PAN501, 3BAD-PAN503, 3BAD-PAN504, 00CHA-PAN801A, 00CHA-PAN814, 00CHA-PAN824, 00CHA-PAN848, 00CHA-PAN854, 00CHA-PAN858, 00CHB-PAN805A, 00CL-PAN001, 00DMW-CAB100, 00DMW-CAB105A, 3EG-PAN002, 3EVM-PAN801, 3GEN-CAB002A, 3GEN-EXC006, 3GEN-CAB003A, 3GEN-CAB007A, 3GG-T801A, 4GG-T801A, 3GG-DAX501, 3H2-LP002, 00LSH-PAN801, 00LSH-PAN802, 00LSH-PAN803, 00LSH-PAN804, 00LSH-PAN862, 00LSH-PAN863, 00LSH-PAN865, 00LSH-PAN866, 00RO-CAB200, 00RO-CAB205, 00RO-CAB225A, 00RO-CAB245A, 00RO-CAB255A, 00RO-CAB275, 00RO-CAB280, 00RO-CAB285, 3SCR-PAN001, 3SCR-PAN002A, 00SSB-EV011, 3TR-CAB004A, 3TR-CAB166 Memberikan data status yang benar ke DCS.

Terminal Block & Internal Wiring Wire Insulation Chafing (Short) Thermal Embrittlement Isolasi rontok/pecah, mengekspos kawat tembaga; Kawat tembaga tersebut sesekali menyentuh kawat lain atau rel logam saat panel bergetar; Status di DCS menjadi tidak bisa dipercaya (Unreliable). Kadang benar, kadang error, tergantung posisi kabel saat itu. Warna kabel memudar (faded) atau kusam; Saat kabel disentuh/digeser sedikit untuk maintenance, isolasinya langsung retak atau patah. Ambil ujung kabel cadangan di area yang sama. Tekuk 180 derajat. Jika isolasi retak, berarti kabel sudah expired secara termal. Ventilasi panel; Penggunaan kabel spek suhu tinggi (jarang untuk kabel kontrol standar). Kabel yang sudah getas termal TIDAK BISA diperbaiki dengan isolasi tape (karena kerusakan ada di sepanjang kabel). Lakukan penggantian kabel total (rewiring) saat overhaul; Pasang sekat penghalang panas jika kabel terpaksa lewat dekat resistor panas. +K3 & LH (KLH), Air Flue Gas (AFG), Boiler (BOL), Sis Pemakaian Sendiri (SPS), Ash Handling (ASH), Coal Handling (CH), Chlorination (CP), Water Treatment Plant (WTP), Generator (GEN), FGD Support (SUP), Screen & Filter (SCR) DC Motor Starter Panel DC Motor Starter Panel 3ABS-PAN861, 3AF-M501A, 3AH-PAN571A, 3AI-PAN501A, 3AI-PAN501B, 3AI-PAN501C, 3AL-M501A, 3AL-M501B, 3APC-MCC502A, 3APC-PD501A, 3APC-PD502, 3APC-PD891, 3APC-PD894, 3APC-PD901, 3APC-PD910, 3APC-PD921, 3APC-PD951, 3BAD-PAN501, 3BAD-PAN503, 3BAD-PAN504, 00CHA-PAN801A, 00CHA-PAN814, 00CHA-PAN824, 00CHA-PAN848, 00CHA-PAN854, 00CHA-PAN858, 00CHB-PAN805A, 00CL-PAN001, 00DMW-CAB100, 00DMW-CAB105A, 3EG-PAN002, 3EVM-PAN801, 3GEN-CAB002A, 3GEN-EXC006, 3GEN-CAB003A, 3GEN-CAB007A, 3GG-T801A, 4GG-T801A, 3GG-DAX501, 3H2-LP002, 00LSH-PAN801, 00LSH-PAN802, 00LSH-PAN803, 00LSH-PAN804, 00LSH-PAN862, 00LSH-PAN863, 00LSH-PAN865, 00LSH-PAN866, 00RO-CAB200, 00RO-CAB205, 00RO-CAB225A, 00RO-CAB245A, 00RO-CAB255A, 00RO-CAB275, 00RO-CAB280, 00RO-CAB285, 3SCR-PAN001, 3SCR-PAN002A, 00SSB-EV011, 3TR-CAB004A, 3TR-CAB167 Memberikan data status yang benar ke DCS.

Terminal Block & Internal Wiring Galvanic Corrosion Salt Mist Intrusion Terbentuk kerak berwarna hijau/putih (Verdigris / Tembaga Klorida) pada terminal dan ujung kabel. Kerak ini bersifat isolator (resistansi tinggi); Resistansi kontak naik drastis. Tegangan sinyal 24VDC drop di terminal yang korosi; Tegangan yang sampai ke DCS mungkin hanya 10-12V (di bawah ambang batas Logic High), sehingga DCS membaca status "OFF" padahal kontak tertutup. Status motor menjadi tidak akurat. Serbuk putih atau hijau kebiruan menumpuk di sekitar baut terminal; Masalah sinyal memburuk saat kelembaban udara tinggi (hujan/malam hari) dan "sembuh" saat kering. Cek adanya kerak hijau; Ukur tegangan across terminal. Jika ada beda potensial > 0.5V pada sambungan tertutup, korosi sudah parah. Ruang Panel ber-AC (Kelembaban terkontrol); Pemanas Panel (Space Heater). Bersihkan kerak dengan cairan Contact Cleaner khusus (bukan amplas, agar plating tidak rusak). Setelah bersih dan kering, semprotkan Conformal Coating atau oleskan Dielectric Grease tipis untuk menyegel logam dari udara garam; Pastikan tekanan udara di ruang panel positif (+ pressure) agar udara luar yang asin tidak menyusup masuk saat pintu ruangan dibuka. +K3 & LH (KLH), Air Flue Gas (AFG), Boiler (BOL), Sis Pemakaian Sendiri (SPS), Ash Handling (ASH), Coal Handling (CH), Chlorination (CP), Water Treatment Plant (WTP), Generator (GEN), FGD Support (SUP), Screen & Filter (SCR) DC Motor Starter Panel DC Motor Starter Panel 3ABS-PAN861, 3AF-M501A, 3AH-PAN571A, 3AI-PAN501A, 3AI-PAN501B, 3AI-PAN501C, 3AL-M501A, 3AL-M501B, 3APC-MCC502A, 3APC-PD501A, 3APC-PD502, 3APC-PD891, 3APC-PD894, 3APC-PD901, 3APC-PD910, 3APC-PD921, 3APC-PD951, 3BAD-PAN501, 3BAD-PAN503, 3BAD-PAN504, 00CHA-PAN801A, 00CHA-PAN814, 00CHA-PAN824, 00CHA-PAN848, 00CHA-PAN854, 00CHA-PAN858, 00CHB-PAN805A, 00CL-PAN001, 00DMW-CAB100, 00DMW-CAB105A, 3EG-PAN002, 3EVM-PAN801, 3GEN-CAB002A, 3GEN-EXC006, 3GEN-CAB003A, 3GEN-CAB007A, 3GG-T801A, 4GG-T801A, 3GG-DAX501, 3H2-LP002, 00LSH-PAN801, 00LSH-PAN802, 00LSH-PAN803, 00LSH-PAN804, 00LSH-PAN862, 00LSH-PAN863, 00LSH-PAN865, 00LSH-PAN866, 00RO-CAB200, 00RO-CAB205, 00RO-CAB225A, 00RO-CAB245A, 00RO-CAB255A, 00RO-CAB275, 00RO-CAB280, 00RO-CAB285, 3SCR-PAN001, 3SCR-PAN002A, 00SSB-EV011, 3TR-CAB004A, 3TR-CAB168 Memberikan data status yang benar ke DCS.

Terminal Block & Internal Wiring Galvanic Corrosion Dissimilar Metal Contact Salah satu sisi sambungan (biasanya baut atau skun) keropos dan hancur menjadi bubuk oksida. Sambungan menjadi longgar secara kimiawi; Sinyal status terputus-putus karena sambungan logam yang hancur; Pada sirkuit arus rendah (DCS) jarang terjadi arcing besar, tapi fluktuasi sinyal akan sangat mengganggu operasi Karat merah (jika baut besi) atau bubuk putih (jika Alumunium) di titik sambungan; Baut terminal macet (seized) karena karat saat hendak dibuka. Periksa material baut dan kabel. Apakah warnanya berbeda (merah tembaga vs putih aluminium vs hitam besi)? Standar penggunaan terminal Tembaga Berlapis Timah (Tin-Plated Copper). Pastikan semua terminal blok dan skun kabel menggunakan material Tin-Plated Copper. Lapisan timah (Tin) bertindak sebagai interface yang aman untuk tembaga maupun aluminium; Jangan pernah mengganti baut terminal yang hilang dengan baut besi biasa dari toko bangunan. Gunakan baut Cadmium atau Nickel plated. +K3 & LH (KLH), Air Flue Gas (AFG), Boiler (BOL), Sis Pemakaian Sendiri (SPS), Ash Handling (ASH), Coal Handling (CH), Chlorination (CP), Water Treatment Plant (WTP), Generator (GEN), FGD Support (SUP), Screen & Filter (SCR) DC Motor Starter Panel DC Motor Starter Panel 3ABS-PAN861, 3AF-M501A, 3AH-PAN571A, 3AI-PAN501A, 3AI-PAN501B, 3AI-PAN501C, 3AL-M501A, 3AL-M501B, 3APC-MCC502A, 3APC-PD501A, 3APC-PD502, 3APC-PD891, 3APC-PD894, 3APC-PD901, 3APC-PD910, 3APC-PD921, 3APC-PD951, 3BAD-PAN501, 3BAD-PAN503, 3BAD-PAN504, 00CHA-PAN801A, 00CHA-PAN814, 00CHA-PAN824, 00CHA-PAN848, 00CHA-PAN854, 00CHA-PAN858, 00CHB-PAN805A, 00CL-PAN001, 00DMW-CAB100, 00DMW-CAB105A, 3EG-PAN002, 3EVM-PAN801, 3GEN-CAB002A, 3GEN-EXC006, 3GEN-CAB003A, 3GEN-CAB007A, 3GG-T801A, 4GG-T801A, 3GG-DAX501, 3H2-LP002, 00LSH-PAN801, 00LSH-PAN802, 00LSH-PAN803, 00LSH-PAN804, 00LSH-PAN862, 00LSH-PAN863, 00LSH-PAN865, 00LSH-PAN866, 00RO-CAB200, 00RO-CAB205, 00RO-CAB225A, 00RO-CAB245A, 00RO-CAB255A, 00RO-CAB275, 00RO-CAB280, 00RO-CAB285, 3SCR-PAN001, 3SCR-PAN002A, 00SSB-EV011, 3TR-CAB004A, 3TR-CAB169 Memberikan data status yang benar ke DCS.

Terminal Block & Internal Wiring Galvanic Corrosion Acidic Coal Dust Sludge Logam terminal terlihat "termakan" (pitting), menipis, dan berwarna hitam legam. Plastik terminal blok mungkin juga rapuh terkena asam; Kawat tembaga kabel sinyal (yang biasanya kecil, 0.75mm) putus total karena diameternya habis dimakan asam. Sinyal hilang permanen (Hard Fault). Terdapat endapan lumpur hitam lengket di terminal blok; Bau menyengat (seperti belerang/telur busuk) saat panel dibuka. Tempelkan kertas lakmus basah pada endapan debu. Jika merah, berarti asam (acidic); Tusuk endapan dengan obeng. Jika logam di bawahnya lunak/hancur, itu korosi asam. Filter debu pada ventilasi panel; Karet pintu panel (Gasket). Terminal yang sudah terkena serangan asam strukturnya sudah rapuh (mikro-pori). Membersihkan saja tidak cukup karena asam sudah meresap. Ganti Terminal Blok dan Potong Ujung Kabel sampai ketemu tembaga segar; Prioritas utama adalah menutup celah masuk debu.

DC Transducer (Current/Voltage Transducer) Zero Drift (Offset) Thermal Drift Output sinyal (4-20mA) bergeser. Misal: Saat arus 0A, outputnya bukan 4mA, tapi 5.6mA; DCS membaca motor sedang menarik arus (misal 10 Ampere), padahal motor mati (Breaker Open); Saat motor jalan beban penuh (100A), DCS mungkin hanya membaca 85A (jika drift negatif). Ini menyebabkan Overload tidak terdeteksi oleh operator, berisiko motor terbakar tanpa peringatan dini. Amperemeter di DCS menunjukkan nilai kecil (bukan nol) saat motor Stop; Pembacaan arus berubah-ubah drastis saat siang hari (panas) vs malam hari (dingin) untuk beban yang sama. Matikan motor. Ukur output mA langsung di terminal transducer. Jika > 4.1 mA atau < 3.9 mA saat arus nol, berarti terjadi thermal drift; Panaskan body transducer sedikit dengan heat gun sambil memonitor outputnya. Jika angka melompat liar, komponen internal sudah tidak stabil. Kompensasi suhu internal pada chip Hall Effect; Ventilasi panel. Lakukan kalibrasi titik nol (Zero Trim) pada transducer secara berkala, terutama saat pergantian musim/suhu ruang berubah; Jika panel terbukti panas, ganti transducer dengan tipe Closed-Loop Hall Effect yang memiliki stabilitas suhu jauh lebih baik daripada tipe Open-Loop murah +K3 & LH (KLH), Air Flue Gas (AFG), Boiler (BOL), Sis Pemakaian Sendiri (SPS), Ash Handling (ASH), Coal Handling (CH), Chlorination (CP), Water Treatment Plant (WTP), Generator (GEN), FGD Support (SUP), Screen & Filter (SCR) DC Motor Starter Panel DC Motor Starter Panel 3ABS-PAN861, 3AF-M501A, 3AH-PAN571A, 3AI-PAN501A, 3AI-PAN501B, 3AI-PAN501C, 3AL-M501A, 3AL-M501B, 3APC-MCC502A, 3APC-PD501A, 3APC-PD502, 3APC-PD891, 3APC-PD894, 3APC-PD901, 3APC-PD910, 3APC-PD921, 3APC-PD951, 3BAD-PAN501, 3BAD-PAN503, 3BAD-PAN504, 00CHA-PAN801A, 00CHA-PAN814, 00CHA-PAN824, 00CHA-PAN848, 00CHA-PAN854, 00CHA-PAN858, 00CHB-PAN805A, 00CL-PAN001, 00DMW-CAB100, 00DMW-CAB105A, 3EG-PAN002, 3EVM-PAN801, 3GEN-CAB002A, 3GEN-EXC006, 3GEN-CAB003A, 3GEN-CAB007A, 3GG-T801A, 4GG-T801A, 3GG-DAX501, 3H2-LP002, 00LSH-PAN801, 00LSH-PAN802, 00LSH-PAN803, 00LSH-PAN804, 00LSH-PAN862, 00LSH-PAN863, 00LSH-PAN865, 00LSH-PAN866, 00RO-CAB200, 00RO-CAB205, 00RO-CAB225A, 00RO-CAB245A, 00RO-CAB255A, 00RO-CAB275, 00RO-CAB280, 00RO-CAB285, 3SCR-PAN001, 3SCR-PAN002A, 00SSB-EV011, 3TR-CAB004A, 3TR-CAB171 Memberikan data status yang benar ke DCS.

DC Transducer (Current/Voltage Transducer) Zero Drift (Offset) Magnetic Remanence Sensor Hall mendeteksi sisa magnet tersebut sebagai "arus listrik"; DCS terus membaca nilai arus positif yang konstan (misal 20 Ampere) meskipun panel sudah dimatikan total; Jika ada logika interlock "Motor must be at 0 Amps to Reset", sistem tidak bisa di-reset karena DCS mengira motor masih berarus. Masalah muncul tepat setelah kejadian Trip arus tinggi atau Short Circuit; Nilai offset di DCS cenderung stabil/tetap, tidak fluktuatif. Lepas transducer dari busbar. Jika output kembali ke 4mA, berarti pengaruh medan magnet luar/busbar. Jika tetap tinggi walaupun sudah dijauhkan dari busbar, inti transducer sudah termagnetisasi. Material inti Low Remanence (misal: Permalloy). Gunakan alat Degausser (penghilang magnet) pada transducer, atau alirkan arus AC bolak-balik yang perlahan dikecilkan untuk menghilangkan sisa magnet; Pertimbangkan transducer dengan desain air-gap lebar yang lebih kebal terhadap saturasi magnetik, meskipun sensitivitasnya sedikit lebih rendah. +K3 & LH (KLH), Air Flue Gas (AFG), Boiler (BOL), Sis Pemakaian Sendiri (SPS), Ash Handling (ASH), Coal Handling (CH), Chlorination (CP), Water Treatment Plant (WTP), Generator (GEN), FGD Support (SUP), Screen & Filter (SCR) DC Motor Starter Panel DC Motor Starter Panel 3ABS-PAN861, 3AF-M501A, 3AH-PAN571A, 3AI-PAN501A, 3AI-PAN501B, 3AI-PAN501C, 3AL-M501A, 3AL-M501B, 3APC-MCC502A, 3APC-PD501A, 3APC-PD502, 3APC-PD891, 3APC-PD894, 3APC-PD901, 3APC-PD910, 3APC-PD921, 3APC-PD951, 3BAD-PAN501, 3BAD-PAN503, 3BAD-PAN504, 00CHA-PAN801A, 00CHA-PAN814, 00CHA-PAN824, 00CHA-PAN848, 00CHA-PAN854, 00CHA-PAN858, 00CHB-PAN805A, 00CL-PAN001, 00DMW-CAB100, 00DMW-CAB105A, 3EG-PAN002, 3EVM-PAN801, 3GEN-CAB002A, 3GEN-EXC006, 3GEN-CAB003A, 3GEN-CAB007A, 3GG-T801A, 4GG-T801A, 3GG-DAX501, 3H2-LP002, 00LSH-PAN801, 00LSH-PAN802, 00LSH-PAN803, 00LSH-PAN804, 00LSH-PAN862, 00LSH-PAN863, 00LSH-PAN865, 00LSH-PAN866, 00RO-CAB200, 00RO-CAB205, 00RO-CAB225A, 00RO-CAB245A, 00RO-CAB255A, 00RO-CAB275, 00RO-CAB280, 00RO-CAB285, 3SCR-PAN001, 3SCR-PAN002A, 00SSB-EV011, 3TR-CAB004A, 3TR-CAB172 Memberikan data status yang benar ke DCS.

Angka digital di layar DCS melompat-lompat cepat padahal beban motor stabil; Ground Loop alarm pada modul analog input DCS. Cek sinyal 4-20mA dengan osiloskop. Anda akan melihat gelombang frekuensi tinggi menumpang di atas garis DC lurus; Periksa shielding kabel sinyal. Apakah terhubung ke ground di KEDUA ujung? (Ini salah, harus satu ujung saja). Kabel Twisted Pair Shielded; Filter software DCS (Smoothing/Damping). Pastikan shield kabel instrumen hanya di-ground di sisi DCS (Marshalling Cabinet). Potong/isolasi shield di sisi panel motor untuk mencegah Ground Loop yang justru menjadi antena noise; Pasang Ferrite Core (cincin ferit) pada kabel sinyal dekat transducer untuk memblokir frekuensi radio (RFI). Pisahkan jalur kabel sinyal (low voltage) minimal 20-30cm dari kabel power utama. +K3 & LH (KLH), Air Flue Gas (AFG), Boiler (BOL), Sis Pemakaian Sendiri (SPS), Ash Handling (ASH), Coal Handling (CH), Chlorination (CP), Water Treatment Plant (WTP), Generator (GEN), FGD Support (SUP), Screen & Filter (SCR) DC Motor Starter Panel DC Motor Starter Panel 3ABS-PAN861, 3AF-M501A, 3AH-PAN571A, 3AI-PAN501A, 3AI-PAN501B, 3AI-PAN501C, 3AL-M501A, 3AL-M501B, 3APC-MCC502A, 3APC-PD501A, 3APC-PD502, 3APC-PD891, 3APC-PD894, 3APC-PD901, 3APC-PD910, 3APC-PD921, 3APC-PD951, 3BAD-PAN501, 3BAD-PAN503, 3BAD-PAN504, 00CHA-PAN801A, 00CHA-PAN814, 00CHA-PAN824, 00CHA-PAN848, 00CHA-PAN854, 00CHA-PAN858, 00CHB-PAN805A, 00CL-PAN001, 00DMW-CAB100, 00DMW-CAB105A, 3EG-PAN002, 3EVM-PAN801, 3GEN-CAB002A, 3GEN-EXC006, 3GEN-CAB003A, 3GEN-CAB007A, 3GG-T801A, 4GG-T801A, 3GG-DAX501, 3H2-LP002, 00LSH-PAN801, 00LSH-PAN802, 00LSH-PAN803, 00LSH-PAN804, 00LSH-PAN862, 00LSH-PAN863, 00LSH-PAN865, 00LSH-PAN866, 00RO-CAB200, 00RO-CAB205, 00RO-CAB225A, 00RO-CAB245A, 00RO-CAB255A, 00RO-CAB275, 00RO-CAB280, 00RO-CAB285, 3SCR-PAN001, 3SCR-PAN002A, 00SSB-EV011, 3TR-CAB004A, 3TR-CAB173 Memberikan data status yang benar ke DCS.

DC Transducer (Current/Voltage Transducer) Output Saturation (Frozen) Inrush Current Saturation Amplifier op-amp di dalam transducer stuck di rail voltage positif. Output tertahan di >22mA (Over-range); DCS menunjukkan arus motor maksimum terus menerus, meskipun motor sebenarnya sudah berjalan normal (low load); Logic DCS mungkin mentripkan motor karena mendeteksi "Locked Rotor" atau "Overcurrent" palsu yang berkepanjangan Grafik tren arus di DCS berbentuk "Flat Top" (rata atas) saat start dan tidak turun-turun; Operator tidak bisa memonitor beban aktual. Matikan power supply transducer (24VDC), lalu nyalakan lagi. Jika output kembali normal, berarti terjadi fenomena Latching akibat saturasi; Bandingkan arus aktual dengan tang ampere vs pembacaan output transducer. Pemilihan range dengan Safety Factor 1.5x - 2x In. Ganti transducer dengan range yang lebih besar (misal 150A atau 200A) untuk mengakomodasi headroom inrush current; Gunakan transducer kualitas industri (seperti LEM atau Phoenix Contact) yang memiliki fitur Anti-Latch atau kemampuan Overload 10x tanpa saturasi permanen. +K3 & LH (KLH), Air Flue Gas (AFG), Boiler (BOL), Sis Pemakaian Sendiri (SPS), Ash Handling (ASH), Coal Handling (CH), Chlorination (CP), Water Treatment Plant (WTP), Generator (GEN), FGD Support (SUP), Screen & Filter (SCR) DC Motor Starter Panel DC Motor Starter Panel 3ABS-PAN861, 3AF-M501A, 3AH-PAN571A, 3AI-PAN501A, 3AI-PAN501B, 3AI-PAN501C, 3AL-M501A, 3AL-M501B, 3APC-MCC502A, 3APC-PD501A, 3APC-PD502, 3APC-PD891, 3APC-PD894, 3APC-PD901, 3APC-PD910, 3APC-PD921, 3APC-PD951, 3BAD-PAN501, 3BAD-PAN503, 3BAD-PAN504, 00CHA-PAN801A, 00CHA-PAN814, 00CHA-PAN824, 00CHA-PAN848, 00CHA-PAN854, 00CHA-PAN858, 00CHB-PAN805A, 00CL-PAN001, 00DMW-CAB100, 00DMW-CAB105A, 3EG-PAN002, 3EVM-PAN801, 3GEN-CAB002A, 3GEN-EXC006, 3GEN-CAB003A, 3GEN-CAB007A, 3GG-T801A, 4GG-T801A, 3GG-DAX501, 3H2-LP002, 00LSH-PAN801, 00LSH-PAN802, 00LSH-PAN803, 00LSH-PAN804, 00LSH-PAN862, 00LSH-PAN863, 00LSH-PAN865, 00LSH-PAN866, 00RO-CAB200, 00RO-CAB205, 00RO-CAB225A, 00RO-CAB245A, 00RO-CAB255A, 00RO-CAB275, 00RO-CAB280, 00RO-CAB285, 3SCR-PAN001, 3SCR-PAN002A, 00SSB-EV011, 3TR-CAB004A, 3TR-CAB174 Memberikan data status yang benar ke DCS.

DCS Blind (Status Error) di mana indikasi lampu LED tidak akurat (Hijau: OFF, Merah: ON, Oranye: Fault) atau alarm gagal mengirim sinyal ke DCS secara otomatis saat trip. DC Transducer (Current/Voltage Transducer) Output Saturation (Frozen) Ground Loop Arus tambahan dari tanah masuk ke sirkuit sinyal 4-20mA; Arus loop ini bisa menambah nilai sinyal asli secara drastis, menyebabkan sinyal menabrak batas atas (Saturation > 20mA). DCS membaca "Over Range" atau "Bad Quality"; Jika arus tanah cukup besar, Input Resistor pada kartu DCS bisa terbakar. Pembacaan arus tidak stabil, berubah saat peralatan besar lain di pabrik di-start (karena pergeseran referensi ground); Nilai arus tidak pernah nol meskipun motor mati. Lepas kabel sinyal (-) di sisi transducer. Ukur tegangan antara kabel tersebut dan terminal (-) transducer. Jika ada tegangan (misal 5-10V), berarti ada beda potensial ground (Ground Loop). Penggunaan kabel Floating (isolated). Pasang Galvanic Isolator (Signal Conditioner) di antara transducer dan DCS. Alat ini memutus hubungan listrik langsung (menggunakan opto-coupler atau trafo) sehingga ground loop terputus total; Pastikan referensi ground untuk sinyal instrumen hanya ada di satu titik (biasanya di sisi DCS/System Ground), jangan di-jumper ke ground bodi panel lokal. +K3 & LH (KLH), Air Flue Gas (AFG), Boiler (BOL), Sis Pemakaian Sendiri (SPS), Ash Handling (ASH), Coal Handling (CH), Chlorination (CP), Water Treatment Plant (WTP), Generator (GEN), FGD Support (SUP), Screen & Filter (SCR) DC Motor Starter Panel DC Motor Starter Panel 3ABS-PAN861, 3AF-M501A, 3AH-PAN571A, 3AI-PAN501A, 3AI-PAN501B, 3AI-PAN501C, 3AL-M501A, 3AL-M501B, 3APC-MCC502A, 3APC-PD501A, 3APC-PD502, 3APC-PD891, 3APC-PD894, 3APC-PD901, 3APC-PD910, 3APC-PD921, 3APC-PD951, 3BAD-PAN501, 3BAD-PAN503, 3BAD-PAN504, 00CHA-PAN801A, 00CHA-PAN814, 00CHA-PAN824, 00CHA-PAN848, 00CHA-PAN854, 00CHA-PAN858, 00CHB-PAN805A, 00CL-PAN001, 00DMW-CAB100, 00DMW-CAB105A, 3EG-PAN002, 3EVM-PAN801, 3GEN-CAB002A, 3GEN-EXC006, 3GEN-CAB003A, 3GEN-CAB007A, 3GG-T801A, 4GG-T801A, 3GG-DAX501, 3H2-LP002, 00LSH-PAN801, 00LSH-PAN802, 00LSH-PAN803, 00LSH-PAN804, 00LSH-PAN862, 00LSH-PAN863, 00LSH-PAN865, 00LSH-PAN866, 00RO-CAB200, 00RO-CAB205, 00RO-CAB225A, 00RO-CAB245A, 00RO-CAB255A, 00RO-CAB275, 00RO-CAB280, 00RO-CAB285, 3SCR-PAN001, 3SCR-PAN002A, 00SSB-EV011, 3TR-CAB004A, 3TR-CAB175 Memberikan data status yang benar ke DCS.

DC Transducer (Current/Voltage Transducer) Output Saturation (Frozen) Open Loop on Output Side Tegangan output pada terminal transducer melonjak ke ~24V (Supply Voltage Rail), tapi arus 0mA; DCS mendeteksi arus < 3.6 mA (Under-range). Sinyal dinyatakan Bad Quality; Jika sinyal arus ini digunakan untuk feedback control (misal: kontrol torsi), sistem akan gagal beroperasi (Trip). Tampilan di HMI/DCS menunjukkan tanda silang (X), berubah warna, atau nilai negatif/nol statis; Alarm "Analog Input Open Circuit". Ukur tegangan di terminal output transducer. Jika terbaca tinggi (misal 24V) tetapi di DCS terbaca 0 Amper, berarti jalur kabel putus (Open Loop). Transducer berusaha mengirim sinyal (tegangan naik) tapi tidak ada beban yang nyambung. Fitur Live Zero (4mA) memungkinkan deteksi kabel putus (0mA vs 4mA). Gunakan Loop Calibrator untuk menyuntikkan arus dari sisi panel ke DCS. Jika tidak masuk, cari titik putus (terminal junction box, marshalling, atau fuse DCS); Beberapa transducer memiliki sekring internal (pico-fuse) untuk proteksi output.

DC Transducer (Current/Voltage Transducer) Power Supply Failure Aux Power Loss Transduser mati (LED indikator padam). Output jatuh ke 0mA atau 0V; Jika sistem menggunakan standar 4-20mA, sinyal 0mA akan langsung dikenali DCS sebagai kerusakan alat (Bad Quality); Jika sistem menggunakan standar lama 0-20mA atau 0-10V, DCS akan membaca 0 Ampere. DCS mengira motor sedang mati, padahal motor mungkin sedang beroperasi beban penuh. Ini sangat berbahaya karena operator tidak sadar alat ukurnya mati. Lampu indikator "Power" atau "Run" pada bodi transduser padam; DCS menunjukkan nilai rata nol (flatline zero) atau tanda silang (X). Ukur tegangan pada terminal Aux Supply transduser. Harus sesuai rating (misal 24VDC). Jika 0V, masalah ada di suplai eksternal (Fuse/MCB). Fuse terpisah untuk sirkuit instrumen; Indikator LED pada unit. Pastikan semua transduser baru menggunakan standar 4-20mA, bukan 0-20mA. Sinyal < 3.6mA adalah tanda pasti kehilangan daya, membedakannya dari kondisi "Motor Stop" (4mA); Beri label jelas pada Fuse/MCB yang menyuplai transduser agar teknisi mudah melacak saat terjadi trip. +K3 & LH (KLH), Air Flue Gas (AFG), Boiler (BOL), Sis Pemakaian Sendiri (SPS), Ash Handling (ASH), Coal Handling (CH), Chlorination (CP), Water Treatment Plant (WTP), Generator (GEN), FGD Support (SUP), Screen & Filter (SCR) DC Motor Starter Panel DC Motor Starter Panel 3ABS-PAN861, 3AF-M501A, 3AH-PAN571A, 3AI-PAN501A, 3AI-PAN501B, 3AI-PAN501C, 3AL-M501A, 3AL-M501B, 3APC-MCC502A, 3APC-PD501A, 3APC-PD502, 3APC-PD891, 3APC-PD894, 3APC-PD901, 3APC-PD910, 3APC-PD921, 3APC-PD951, 3BAD-PAN501, 3BAD-PAN503, 3BAD-PAN504, 00CHA-PAN801A, 00CHA-PAN814, 00CHA-PAN824, 00CHA-PAN848, 00CHA-PAN854, 00CHA-PAN858, 00CHB-PAN805A, 00CL-PAN001, 00DMW-CAB100, 00DMW-CAB105A, 3EG-PAN002, 3EVM-PAN801, 3GEN-CAB002A, 3GEN-EXC006, 3GEN-CAB003A, 3GEN-CAB007A, 3GG-T801A, 4GG-T801A, 3GG-DAX501, 3H2-LP002, 00LSH-PAN801, 00LSH-PAN802, 00LSH-PAN803, 00LSH-PAN804, 00LSH-PAN862, 00LSH-PAN863, 00LSH-PAN865, 00LSH-PAN866, 00RO-CAB200, 00RO-CAB205, 00RO-CAB225A, 00RO-CAB245A, 00RO-CAB255A, 00RO-CAB275, 00RO-CAB280, 00RO-CAB285, 3SCR-PAN001, 3SCR-PAN002A, 00SSB-EV011, 3TR-CAB004A, 3TR-CAB177 Memberikan data status yang benar ke DCS.

DC Transducer (Current/Voltage Transducer) Power Supply Failure Capacitor Drying Tegangan internal tidak stabil (rippling). Elektronik transduser bekerja tidak menentu atau mati total; Sebelum mati total, sinyal output akan mengandung noise frekuensi rendah yang membuat pembacaan di DCS naik-turun tidak wajar; Nilai pembacaan melayang jauh dari nilai aktual. Sinyal DCS menjadi noisy padahal beban motor stabil; Umur transduser sudah tua (> 10 tahun) di lingkungan panas. Cek sinyal output. Jika terlihat gelombang gergaji atau noise AC yang menumpuk pada sinyal DC, kapasitor filter internal sudah kering; Ganti dengan unit baru. Jika masalah hilang, unit lama rusak internal (aging). Rating suhu komponen (Industrial Grade 85 C/105 C). Transduser elektronik di lingkungan panas memiliki umur pakai terbatas (biasanya 10-12 tahun). Jadwalkan penggantian proaktif sebelum kapasitor gagal total; Perbaiki ventilasi panel untuk menurunkan laju pengeringan kapasitor (setiap kenaikan 10 C memangkas umur kapasitor setengahnya). +K3 & LH (KLH), Air Flue Gas (AFG), Boiler (BOL), Sis Pemakaian Sendiri (SPS), Ash Handling (ASH), Coal Handling (CH), Chlorination (CP), Water Treatment Plant (WTP), Generator (GEN), FGD Support (SUP), Screen & Filter (SCR) DC Motor Starter Panel DC Motor Starter Panel 3ABS-PAN861, 3AF-M501A, 3AH-PAN571A, 3AI-PAN501A, 3AI-PAN501B, 3AI-PAN501C, 3AL-M501A, 3AL-M501B, 3APC-MCC502A, 3APC-PD501A, 3APC-PD502, 3APC-PD891, 3APC-PD894, 3APC-PD901, 3APC-PD910, 3APC-PD921, 3APC-PD951, 3BAD-PAN501, 3BAD-PAN503, 3BAD-PAN504, 00CHA-PAN801A, 00CHA-PAN814, 00CHA-PAN824, 00CHA-PAN848, 00CHA-PAN854, 00CHA-PAN858, 00CHB-PAN805A, 00CL-PAN001, 00DMW-CAB100, 00DMW-CAB105A, 3EG-PAN002, 3EVM-PAN801, 3GEN-CAB002A, 3GEN-EXC006, 3GEN-CAB003A, 3GEN-CAB007A, 3GG-T801A, 4GG-T801A, 3GG-DAX501, 3H2-LP002, 00LSH-PAN801, 00LSH-PAN802, 00LSH-PAN803, 00LSH-PAN804, 00LSH-PAN862, 00LSH-PAN863, 00LSH-PAN865, 00LSH-PAN866, 00RO-CAB200, 00RO-CAB205, 00RO-CAB225A, 00RO-CAB245A, 00RO-CAB255A, 00RO-CAB275, 00RO-CAB280, 00RO-CAB285, 3SCR-PAN001, 3SCR-PAN002A, 00SSB-EV011, 3TR-CAB004A, 3TR-CAB178 Memberikan data status yang benar ke DCS.

DC Transducer (Current/Voltage Transducer) Power Supply Failure Conductive Dust Short Circuit Terjadi hubung singkat internal (internal short). Komponen terbakar, mungkin disertai ledakan kecil atau asap; Short circuit di dalam transduser dapat menyebabkan MCB suplai 24VDC utama satu panel trip, mematikan seluruh instrumen lain di panel tersebut (Common Mode Failure); Kehilangan pantauan seluruh panel. Bau komponen elektronik terbakar (sangit); MCB Kontrol/Instrumen trip dan tidak bisa di-reset. Lepas kabel power transduser. Coba reset MCB utama. Jika MCB bisa ON, berarti transduser tersebut yang short; Cek resistansi antara terminal power transduser (posisi lepas). Jika 0 Ohm, internal short. Conformal Coating pada PCB (pada tipe high-end); IP Rating Casing (IP20/IP40). Saat membeli spare part, spesifikasikan transduser yang PCB-nya memiliki pelapis pelindung (conformal coating) agar tahan debu konduktif dan kelembaban; Gunakan transduser tipe potted (dicor resin penuh) untuk area yang sangat berdebu.

Magnetic Contactor (Main Contacts) Contact Welding Contact Bounce permukaan kontak kasar, berlubang (pitted), dan akhirnya menyatu; Awalnya motor mungkin tersendat saat start; Akhirnya, kontak menyatu permanen. Motor tidak bisa distop. Terdengar suara "Buzzing" kasar atau "Chattering" (buk-buk-buk cepat) dari panel saat motor start; Lampu indikator panel mungkin berkedip saat start. Lihat gelombang tegangan koil saat start dengan osiloskop; Lakukan inspeksi visual. permukaan kontak terlihat kasar seperti kawah bulan (cratered). Desain Wiping Action pada kontak (gesekan saat menutup untuk membersihkan oksida dan mengurangi bounce); Koil elektronik Wide Voltage Range. Pastikan tegangan kontrol (biasanya 110VDC/220VDC) stabil dan tidak drop saat inrush. Tegangan rendah menyebabkan gaya tarik magnet lemah yang menyebabkan bouncing; Jika kontaktor sudah pernah mengalami chattering parah, GANTI BARU. Jangan diamplas, karena lapisan plating pelindung sudah hilang. +K3 & LH (KLH), Air Flue Gas (AFG), Boiler (BOL), Sis Pemakaian Sendiri (SPS), Ash Handling (ASH), Coal Handling (CH), Chlorination (CP), Water Treatment Plant (WTP), Generator (GEN), FGD Support (SUP), Screen & Filter (SCR) DC Motor Starter Panel DC Motor Starter Panel 3ABS-PAN861, 3AF-M501A, 3AH-PAN571A, 3AI-PAN501A, 3AI-PAN501B, 3AI-PAN501C, 3AL-M501A, 3AL-M501B, 3APC-MCC502A, 3APC-PD501A, 3APC-PD502, 3APC-PD891, 3APC-PD894, 3APC-PD901, 3APC-PD910, 3APC-PD921, 3APC-PD951, 3BAD-PAN501, 3BAD-PAN503, 3BAD-PAN504, 00CHA-PAN801A, 00CHA-PAN814, 00CHA-PAN824, 00CHA-PAN848, 00CHA-PAN854, 00CHA-PAN858, 00CHB-PAN805A, 00CL-PAN001, 00DMW-CAB100, 00DMW-CAB105A, 3EG-PAN002, 3EVM-PAN801, 3GEN-CAB002A, 3GEN-EXC006, 3GEN-CAB003A, 3GEN-CAB007A, 3GG-T801A, 4GG-T801A, 3GG-DAX501, 3H2-LP002, 00LSH-PAN801, 00LSH-PAN802, 00LSH-PAN803, 00LSH-PAN804, 00LSH-PAN862, 00LSH-PAN863, 00LSH-PAN865, 00LSH-PAN866, 00RO-CAB200, 00RO-CAB205, 00RO-CAB225A, 00RO-CAB245A, 00RO-CAB255A, 00RO-CAB275, 00RO-CAB280, 00RO-CAB285, 3SCR-PAN001, 3SCR-PAN002A, 00SSB-EV011, 3TR-CAB004A, 3TR-CAB181 Menghentikan motor saat diperintah Stop.

Magnetic Contactor (Main Contacts) Broken Return Spring Thermal Annealing Pegas menyusut/memendek. Tekanan balik menjadi sangat lemah, meskipun fisik pegas belum patah; Kontak membuka sangat lambat saat stop, memicu busur api besar yang merusak kontak; Karena tekanan pembukaan lemah, jika ada sedikit saja micro-weld (las titik) pada kontak, pegas tidak kuat memisahkannya. Kontaktor jadi macet total di posisi tertutup. Body kontaktor terasa sangat panas saat disentuh (hati-hati!); Gerakan kontaktor saat membuka terlihat lambat/lemas (tidak ada suara "cetek" yang tegas); Fisik pegas berubah warna menjadi biru/hitam (gosong). Bongkar casing atas. Bandingkan panjang pegas dengan pegas baru. Pegas yang annealed akan terlihat lebih pendek (melesak); Deteksi sumber panas di sekitar terminal kontak. Inspeksi Thermography rutin; Material isolator tahan panas. Pegas yang melunak adalah gejala, bukan akar masalah. Cari sumber panasnya (Terminal kendor? Beban overload?) dan perbaiki itu dulu; Sifat baja pegas yang sudah annealed tidak bisa dikembalikan.

Magnetic Contactor (Main Contacts) Broken Return Spring Fatigue Patah lelah (fatigue fracture), biasanya patahan tegak lurus sumbu kawat pegas dengan permukaan kasar; Pecahan pegas bisa mengganjal mekanisme crossbar. Kadang motor bisa stop, kadang tidak; Mekanisme miring karena ganjalan pegas bisa menyebabkan satu kutub terbuka tapi kutub lain tertutup, menyebabkan kondisi busur api tak terkendali. Umur pakai kontaktor sudah sangat lama (> 5-10 tahun atau jutaan operasi); Sering dilakukan inching (start-stop cepat) oleh operator. Lihat permukaan patahan pegas dengan kaca pembesar. Patahan akibat fatigue biasanya memiliki pola garis-garis pantai (beach marks) yang khas. Spesifikasi Mechanical Durability (misal: 10 juta operasi); Operations Counter pada DCS untuk maintenance prediktif. Monitor jumlah operasi kontaktor via DCS.

Magnetic Contactor (Main Contacts) Residual Magnetism Loss of Air Gap Terjadi kontak fisik sempurna antara dua permukaan besi magnet. Sisa fluks magnet sekecil apapun akan mengunci kedua permukaan tersebut dengan kuat (Closed Magnetic Loop); Saat tombol Stop ditekan, arus koil 0 Ampere, tapi armature tetap menempel di inti magnet. Kontak utama tetap tertutup; Motor terus beroperasi. Operator harus mematikan lewat Breaker utama (Emergency) untuk menghentikannya. Kontaktor merespon lambat (sluggish) saat dimatikan; Tidak terdengar bunyi "Clack" tegas saat Stop (karena armature tidak lepas). Matikan breaker utama. Selipkan selembar kertas tipis di antara inti magnet dan armature. Tekan armature manual (close), lalu lepas.

Gagal Stop (Fail to Stop) di mana kontaktor gagal memutus aliran daya saat perintah OFF atau Emergency Stop, atau handle MCCB gagal diputar ke posisi OFF sempurna untuk digembok. Magnetic Contactor (Main Contacts) Residual Magnetism DC Polarization Inti besi memiliki gaya tarik magnet sendiri meskipun koil dilepas; Motor tidak bisa distop via sistem kontrol otomatis/proteksi. Saat panel dimatikan total (Power Off), jika Anda mendekatkan obeng ke inti besi kontaktor, obeng tersebut menempel kuat (seperti menempel pada magnet speaker). Gunakan tes obeng seperti di atas. Pada kondisi normal, inti besi kontaktor harusnya soft magnetic (tidak menarik logam saat koil mati); Ukur gaya yang dibutuhkan untuk menarik armature terbuka. Jika terasa sangat berat di awal tarikan padahal koil mati, itu adalah gaya magnet sisa. Penggunaan material Soft Magnetic Iron (Silicon Steel) yang sulit menjadi magnet permanen. Inti besi yang sudah terpolarisasi permanen sulit diperbaiki (butuh proses degaussing yang ribet). Solusi paling aman dan cepat adalah mengganti kontaktor; Terkadang magnet sisa wajar ada sedikit. Pastikan pegas pengembalian (Return Spring) masih cukup kuat untuk mematahkan gaya magnet sisa tersebut.

Kontaktor segera memutus aliran daya saat perintah OFF atau Emergency Stop; handle MCCB dapat diputar ke posisi OFF sempurna dan digembok. Gagal Stop (Fail to Stop) di mana kontaktor gagal memutus aliran daya saat perintah OFF atau Emergency Stop, atau handle MCCB gagal diputar ke posisi OFF sempurna untuk digembok. Control Wiring & Circuit Capacitive/Inductive Coupling Lack of Shielding Kabel menyerap noise RFI/EMI dari lingkungan; Jika kabel ini terhubung ke input Digital DCS (untuk memutus kontaktor), noise tinggi bisa dibaca sebagai sinyal "High" (1) oleh DCS, sehingga DCS tidak pernah mengirim perintah Stop ke output. Sinyal input di DCS berkedip-kedip atau status tidak stabil (flickering); Gangguan terjadi saat peralatan besar (seperti Inverter/VFD) di dekatnya beroperasi. Lihat kode kabel pada kulit kabel. Apakah tertulis kode pelindung (misal: "CY", "S", atau "Shielded")? Jika hanya PVC/PVC biasa, berarti tidak ada shield. Spesifikasi kabel instrumen standar (misal: Overall Screen); Konduit baja (Rigid Steel Conduit). Ganti kabel kontrol dengan tipe Twisted Pair with Overall Shield; Pastikan shield (pelindung) kabel di-grounding hanya pada SATU SISI (biasanya di sisi panel kontrol/DCS). JANGAN meng-ground kedua sisi karena akan menciptakan Ground Loop yang justru mengalirkan arus gangguan dan memperparah masalah gagl stop. \ No newline at end of file diff --git a/be-ircfa/src/root_cause/fmea_data/FMEA TJB - 13_Steam Drain Trap.tsv b/be-ircfa/src/root_cause/fmea_data/FMEA TJB - 13_Steam Drain Trap.tsv new file mode 100644 index 0000000..d750835 --- /dev/null +++ b/be-ircfa/src/root_cause/fmea_data/FMEA TJB - 13_Steam Drain Trap.tsv @@ -0,0 +1,57 @@ +System Equipment Type Equipment Tag Function Standard Performance of Function Functional Failures Part/Component causing Failure Failure Modes Potential Cause(s) of failure mode Effects of Equipment Failure Initial Indications/Symptoms Action to Confirm Current Design Controls/Fault Detection Recommended Action(s) Actions Taken Cost Analysis +Boiler Steam Drain Trap Steam Drain Trap 3AI-Q501, 3AI-Q502, 3AI-Q503, 3AI-Q504, 3AI-Q506, 3AI-Q508, 3AI-Q507, 3AI-Q510 Membuang kondensat segera setelah terbentuk untuk menjaga efisiensi transfer panas.

Lakukan ECT saat shutdown. Cari sinyal cacat (defect) yang bertepatan dengan lokasi support plate; Inspeksi visual sisi shell untuk melihat jejak gesekan pada tube di area support plate. Support plate dipasang pada jarak yang ditentukan menggunakan stay bolts dan spacers untuk mencegah kontak antar tube dan menahan getaran. Jika ECT mendeteksi fretting wear, lakukan staking (penganjalan) pada tube tersebut menggunakan pasak logam/plastik khusus (tube stakes) untuk mematikan gerakan tube tanpa perlu menyumbatnya (plugging), jika akses memungkinkan. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Memanaskan feed water (air umpan) menggunakan uap ekstraksi superheated dari temperatur 170.3 C menjadi 211.5 C Laju Alir feed water: 1,998,594 kg/h; Suhu Masuk: 170.3 C; Suhu Keluar: 211.5 C; Terminal Temp.

Jika kecepatan kritis terlampaui, tube akan bergetar tak terkendali dan bertabrakan dengan tube di sebelahnya (mid-span collision). Suara dengungan keras (humming) atau siulan (singing) dari heater. Manual menyebutkan "Abnormal noise" sebagai tanda bahaya yang mengharuskan penghentian segera. Analisis spektrum suara untuk menentukan apakah frekuensi dominan cocok dengan frekuensi natural tube; Jika suara sangat keras, segera kurangi beban atau isolasi heater untuk mencegah kerusakan total tube bundle. Jarak penyangga (support plate) didesain untuk memastikan frekuensi natural tube berada di atas frekuensi eksitasi uap; Penggunaan orifice pada partisi (32.9 mm) untuk menjaga kestabilan aliran bypass. Saat inspeksi kebocoran, cek apakah kerusakan tube membentuk pola tertentu (misal: di pinggiran bundle atau di area window baffle). Pola ini mengindikasikan masalah aliran spesifik; Jika resonansi terkonfirmasi, pasang anti-vibration bars atau stakes tambahan di antara tube. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Memanaskan feed water (air umpan) menggunakan uap ekstraksi superheated dari temperatur 170.3 C menjadi 211.5 C Laju Alir feed water: 1,998,594 kg/h; Suhu Masuk: 170.3 C; Suhu Keluar: 211.5 C; Terminal Temp.

Kecepatan uap meningkat tajam, memicu getaran; Fluktuasi beban yang terlalu cepat (rapid load change) menyebabkan perubahan densitas dan kecepatan uap yang mendadak (transient vibration). Laju perubahan suhu (rate of change) melebihi batas kurva desain, atau aliran uap ekstraksi melebihi 114,900 kg/h; Getaran transien (muncul-hilang) saat perubahan beban. Periksa data history DCS. Apakah kerusakan tube berkorelasi dengan periode operasi heater cut atau fast ramp-up? Batasan operasional yang ketat mengenai laju perubahan suhu dan prosedur heater cut. Manual menyarankan operasi heater cut tidak dilakukan dalam jangka waktu lama. Patuhi batasan laju perubahan suhu (<200 C/h) secara ketat; Jika terpaksa beroperasi dalam mode heater cut (HPH lain mati), pantau vibrasi HPH 5 secara intensif. Jangan memaksakan beban penuh jika vibrasi terdeteksi. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Memanaskan feed water (air umpan) menggunakan uap ekstraksi superheated dari temperatur 170.3 C menjadi 211.5 C Laju Alir feed water: 1,998,594 kg/h; Suhu Masuk: 170.3 C; Suhu Keluar: 211.5 C; Terminal Temp.

Flashing at Subcooler Poor water level control Terjadi Steam Blow-through (uap menerobos masuk ke zona pendingin drain). Uap berkecepatan tinggi bercampur kondensat menyebabkan erosi/kikis pada tube di zona drain cooling dan baffle internal; Campuran uap dan air mengalir deras ke Deaerator (tujuan drain HPH 5); Energi tinggi dari uap yang lolos dapat merusak tray (nampan) internal Deaerator akibat flooding atau hammering. Pembacaan level di DCS menunjukkan angka rendah atau hunting; Nilai DCA melonjak tinggi (menjauh dari desain 5.6 C) karena uap masuk ke area pengukuran suhu drain; Suara hammering atau gemuruh pada pipa drain menuju Deaerator. Verifikasi level air aktual di gelas duga (sight glass) lokal. Bandingkan dengan DCS; Cek respons Drain Control Valve. Apakah valve membuka penuh padahal level sudah rendah? (Indikasi controller tuning salah atau valve macet). Sistem kontrol level otomatis yang mengatur bukaan drain valve; Pelat pembatas untuk memastikan water seal terbentuk. Operational: Naikkan Setpoint level air sedikit di atas normal sementara waktu untuk memastikan subcooling zone terendam sempurna, lalu observasi apakah suara/vibrasi hilang; Maintenance: Kalibrasi ulang transmiter level. Pastikan zero point transmiter sesuai dengan elevasi fisik subcooler inlet. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Memanaskan feed water (air umpan) menggunakan uap ekstraksi superheated dari temperatur 170.3 C menjadi 211.5 C Laju Alir feed water: 1,998,594 kg/h; Suhu Masuk: 170.3 C; Suhu Keluar: 211.5 C; Terminal Temp.

Kondensat panas atau uap dari condensing zone bocor masuk ke drain cooling zone melalui celah tersebut, melewati jalur pendinginan yang seharusnya (tube); Efisiensi termal HPH turun karena panas drain tidak terserap maksimal oleh feed water; Suhu drain outlet lebih panas dari desain. Nilai Drain Cooler Approach (DCA) tinggi secara konsisten meskipun level air normal. (Desain DCA HPH 5 adalah 5.6 C). Jika DCA terbaca misal 15-20 C, indikasi kuat ada internal bypass; Level air mungkin terlihat normal dan stabil, membuat operator terkecoh bahwa kondisi aman. Hitung DCA aktual pada beban 100%. Jika DCA > Design + Margin dan level normal, curigai kebocoran shroud; Saat shutdown, masuk ke dalam shell (jika akses memungkinkan) atau gunakan kamera inspeksi untuk melihat kondisi lasan enclosing plate. Enclosing plate dilas kuat ke struktur internal; Pelat pembatas biasanya terbuat dari material yang tahan erosi. Lakukan pengelasan ulang (re-welding) pada celah/retakan shroud saat overhaul; Lakukan ECT (Eddy Current Test) khusus pada baris tube yang berdekatan dengan enclosing plate untuk mendeteksi penipisan dinding akibat erosi kebocoran shroud. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Menahan tekanan fluida pada sisi tube 232 bar(g) dan sisi shell 21.3 bar(g) Tekanan Desain Sisi Tube: 232.0 bar(g); Tekanan Desain Sisi Shell: 21.3 bar(g); Suhu Desain Sisi Shell: 218 C (Inlet Steam: 488 C) Gagal menahan tekanan fluida pada sisi tube pada 232 bar(g) dan shell pada 21.3 bar(g) BFP Speed Controller (DCS Logic), Feedwater Control Valve Actuator. Abnormal instrument reading Control failure Jika kontroler gagal membuka drain valve saat level/tekanan naik, ruang uap di shell akan terkompresi oleh air yang naik (banjir), menyebabkan lonjakan tekanan hidrolik pada shell yang didesain hanya untuk 21.3 bar; Risiko Shell Relief Valve bekerja (popping). Jika relief valve gagal membuka, shell dapat pecah/deformasi Alarm "Heater Pressure High" tidak muncul (jika kontroler hang), atau muncul terlambat; Safety Valve menyembur (popping) atau suara aliran deras di pipa buang safety valve. Bandingkan posisi fisik control valve dengan sinyal output di DCS; Cek tekanan aktual pada pressure gauge lokal di sisi shell. Dilengkapi Relief Valve sisi Shell sebagai proteksi lapis terakhir; Trip HHWL (High-High Water Level) yang menutup isolasi uap ekstraksi secara independen dari kontroler drain. Lakukan simulasi sinyal (loop test) pada logika pembukaan Emergency Drain Valve saat shutdown; Cek respons kontroler PID terhadap perubahan sinyal input (step test). +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Menahan tekanan fluida pada sisi tube 232 bar(g) dan sisi shell 21.3 bar(g) Tekanan Desain Sisi Tube: 232.0 bar(g); Tekanan Desain Sisi Shell: 21.3 bar(g); Suhu Desain Sisi Shell: 218 C (Inlet Steam: 488 C) Gagal menahan tekanan fluida pada sisi tube pada 232 bar(g) dan shell pada 21.3 bar(g) Shell Pressure Transmitter Sensing Line Abnormal instrument reading Corrosion Jalur impuls (sensing line) ke transmitter tekanan tersumbat karat/sedimen. Tekanan yang terbaca di DCS menjadi statis atau lebih rendah dari aktual (False Low); Operator mengira tekanan aman, padahal tekanan aktual naik (misal karena tube leak). Tindakan mitigasi manual terlambat. Tekanan berlebih dapat merusak gasket flange atau expansion joint. Grafik tren tekanan di DCS terlihat rata (flatline) atau sangat lambat bereaksi terhadap perubahan beban unit; Perbedaan besar antara indikator lokal dan ruang kontrol. Lakukan blowdown / flushing pada jalur impuls transmitter. Jika banyak kotoran keluar dan pembacaan kembali normal, penyebabnya terkonfirmasi. Biasanya terdapat >1 transmitter untuk parameter kritis (Voting 2oo3 atau 1oo2); Tubing instrumen biasanya bermaterial Stainless Steel untuk mengurangi korosi. Jadwalkan blowdown instrumen secara berkala, terutama setelah unit lama shutdown (karena korosi sering terjadi saat stagnan); Pastikan material tubing sesuai spesifikasi anti-korosi (SS316L). +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Menahan tekanan fluida pada sisi tube 232 bar(g) dan sisi shell 21.3 bar(g) Tekanan Desain Sisi Tube: 232.0 bar(g); Tekanan Desain Sisi Shell: 21.3 bar(g); Suhu Desain Sisi Shell: 218 C (Inlet Steam: 488 C) Gagal menahan tekanan fluida pada sisi tube pada 232 bar(g) dan shell pada 21.3 bar(g) Feedwater Pressure Transmitter, Shell Pressure Transmitter Abnormal instrument reading Faulty signal/indication/alarm Kesalahan pembacaan tekanan; HPH 5 beroperasi di atas batas desain tanpa disadari. Siklus fatigue pada material shell meningkat. Jika terjadi transient tekanan, batas aman (safety margin) sudah terlampaui. Alarm deviasi antara transmitter A dan B (jika ada); Ketidakcocokan antara tekanan jenuh (P-sat) yang dihitung dari temperatur uap dengan pembacaan tekanan aktual. Pasang calibrator standar ke transmitter dan cek akurasinya. Logika DCS membandingkan sinyal antar sensor redundan. Lakukan kalibrasi rutin setiap outage; Lakukan validasi silang (cross-check) data tekanan dengan data temperatur (menggunakan tabel uap) secara berkala. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Menahan tekanan fluida pada sisi tube 232 bar(g) dan sisi shell 21.3 bar(g) Tekanan Desain Sisi Tube: 232.0 bar(g); Tekanan Desain Sisi Shell: 21.3 bar(g); Suhu Desain Sisi Shell: 218 C (Inlet Steam: 488 C) Gagal menahan tekanan fluida pada sisi tube pada 232 bar(g) dan shell pada 21.3 bar(g) Pressure Transmitter Electronic Module. Abnormal instrument reading Instrument failure-general Hilangnya pemantauan tekanan sisi shell atau tube; Jika logika kontrol diset Fail-Open pada drain, efisiensi turun. Jika Fail-Close, risiko overpressure tinggi jika terjadi kebocoran tube (tube rupture) bersamaan dengan hilangnya indikasi. Sinyal analog jammed di >20mA atau <4mA; Indikasi "BAD PV" atau warna ungu/kuning pada tampilan HMI/DCS. Cek status error pada layar lokal transmitter atau gunakan HART Communicator Sistem biasanya memaksa Emergency Drain membuka jika sinyal level/tekanan hilang total. Sediakan spare unit transmitter yang sudah dikonfigurasi; Ganti instrumen yang sudah melebihi masa pakai ekonomis (misal >10-15 tahun). +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Menahan tekanan fluida pada sisi tube 232 bar(g) dan sisi shell 21.3 bar(g) Tekanan Desain Sisi Tube: 232.0 bar(g); Tekanan Desain Sisi Shell: 21.3 bar(g); Suhu Desain Sisi Shell: 218 C (Inlet Steam: 488 C) Gagal menahan tekanan fluida pada sisi tube pada 232 bar(g) dan shell pada 21.3 bar(g) Pressure Instrument Wiring Terminals, Junction Box Terminals Abnormal instrument reading Looseness Sinyal tekanan berfluktuasi tajam (spikes) akibat getaran mesin; Sinyal palsu ini dapat memicu pembukaan Safety Valve (jika sistemnya pilot operated) atau pembukaan Drain Valve secara mendadak, menyebabkan pressure shock pada sistem perpipaan. Grafik tekanan menunjukkan garis-garis vertikal (spikes) acak yang tidak berkorelasi dengan proses. Cek kekencangan terminal di Junction Box dan baut mounting bracket transmitter. Time delay atau damping pada DCS untuk mengabaikan lonjakan sinyal mikro-detik. Kencangkan terminal kabel menggunakan obeng torsi.

Bergantung sepenuhnya pada proteksi mekanis (Safety Valve). Nilai atau indikator putus koneksi pada DCS; Alarm "I/O Module Fault" atau "Loop Open". Cek tegangan 24VDC pada loop instrumen dan kontinuitas kabel. Modul I/O DCS memantau impedansi loop untuk mendeteksi kabel putus. Pastikan jalur kabel instrumen dilindungi conduit atau tray tertutup untuk menghindari kerusakan fisik akibat pekerjaan perawatan lain. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Menahan tekanan fluida pada sisi tube 232 bar(g) dan sisi shell 21.3 bar(g) Tekanan Desain Sisi Tube: 232.0 bar(g); Tekanan Desain Sisi Shell: 21.3 bar(g); Suhu Desain Sisi Shell: 218 C (Inlet Steam: 488 C) Gagal menahan tekanan fluida pada sisi tube pada 232 bar(g) dan shell pada 21.3 bar(g) DCS Pressure Range/Scale Setting Abnormal instrument reading Out of adjustment Alarm "High Pressure" tidak berbunyi meskipun tekanan sudah mendekati batas desain (21.3 bar untuk shell). Operator kehilangan kesempatan untuk intervensi sebelum Safety Valve bekerja; Alarm palsu (nuisance alarm) sering muncul, membuat operator mengabaikan alarm yang sebenarnya (alarm fatigue). Tekanan aktual normal tapi alarm aktif, atau tekanan tinggi tapi alarm diam. Verifikasi nilai Trip/Alarm Setpoint di logika DCS dibandingkan dengan dokumen Operating Manual atau Datasheet. Pengubahan setpoint diproteksi password engineering. Lakukan audit setpoint alarm/trip secara berkala (misal: tahunan) dan pastikan sesuai dengan revisi manual terbaru (Tekanan desain Shell: 21.3 bar, Tube: 232 bar); Terapkan prosedur Management of Change ketat untuk setiap perubahan parameter instrumen. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Menahan tekanan fluida pada sisi tube 232 bar(g) dan sisi shell 21.3 bar(g) Tekanan Desain Sisi Tube: 232.0 bar(g); Tekanan Desain Sisi Shell: 21.3 bar(g); Suhu Desain Sisi Shell: 218 C (Inlet Steam: 488 C) Gagal menahan tekanan fluida pada sisi tube pada 232 bar(g) dan shell pada 21.3 bar(g) Manway Pressure Seal Gasket, Feedwater Inlet/Outlet Nozzle Flange Gaskets.

Semburan ini dapat membakar kulit atau memotong material lunak tanpa peringatan visual yang jelas.Kerusakan pada isolasi termal (lagging) dan cladding aluminium di sekitar titik bocor; Kehilangan energi panas yang seharusnya dipakai untuk memanaskan feed water, menyebabkan sedikit kenaikan Heat Rate (penurunan efisiensi). Suara mendesis atau siulan nyaring dari area sambungan pipa uap ekstraksi atau badan heater; Terlihat "gelombang panas" (heat shimmer/mirage) di udara sekitar titik bocor; Kondensasi atau air menetes dari cladding isolasi (jika bocor di area drain). Gunakan kamera inframerah untuk melihat plume panas yang keluar dari celah flange atau isolasi; Gunakan alat pendengar ultrasonik untuk melokalisir sumber kebocoran di lingkungan yang bising. Spesifikasi gasket sisi uap biasanya menggunakan Spiral Wound Gasket dengan filler Grafit atau Mika yang tahan suhu tinggi (>500 C); Beberapa valve atau sambungan kritis dilengkapi nampan penampung (drip pan) yang dialirkan ke drainase lantai agar tidak membasahi lantai/peralatan lain; Shell Relief Valve melindungi dari tekanan berlebih yang bisa merusak gasket. Jika kebocoran kecil tapi mengganggu, pertimbangkan pemasangan Online Leak Sealing (injeksikan compound penutup bocor) sebagai solusi sementara hingga outage berikutnya; Ganti gasket setiap kali sambungan dibuka.

Tekanan internal naik mendekati Setting Pressure Safety Valve; Shell Relief Valve akan bekerja (lift/pop). Jika sumbatan total dan beban unit tinggi, kapasitas relief valve mungkin tidak cukup membuang debit kondensat (karena didesain untuk uap/tube rupture), berisiko deformasi shell. Indikasi Normal Drain Control Valve membuka 100% (saturasi), namun Level HPH 5 tetap naik tinggi; Alarm "Heater Level High" diikuti "Heater Level High-High"; Tekanan shell terbaca lebih tinggi dari tekanan saturasi uap inlet. Periksa posisi fisik stem drain valve; Coba buka Drain Bypass Valve (jika ada) secara manual. Jika level turun saat bypass dibuka, berarti jalur utama atau control valve tersumbat. Jalur Emergency Drain ke Kondensor akan membuka otomatis jika jalur Normal Drain (ke Deaerator) gagal mengatasi level; Biasanya terdapat saringan (strainer) sebelum control valve untuk menangkap kotoran. Bongkar dan bersihkan strainer drain secara rutin, terutama pasca-overhaul di mana sisa las/gasket sering tertinggal; Pantau Differential Pressure (dP) pada strainer jika tersedia instrumennya. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Menahan tekanan fluida pada sisi tube 232 bar(g) dan sisi shell 21.3 bar(g) Tekanan Desain Sisi Tube: 232.0 bar(g); Tekanan Desain Sisi Shell: 21.3 bar(g); Suhu Desain Sisi Shell: 218 C (Inlet Steam: 488 C) Gagal menahan tekanan fluida pada sisi tube pada 232 bar(g) dan shell pada 21.3 bar(g) BFP Overpressure Trip Interlock Parameter deviation Control failure Kontroler DCS atau Positioner katup gagal merespons kenaikan level, menyebabkan katup tertutup atau tertahan (stuck) saat beban tinggi. Perbedaan besar antara Setpoint (SP) level dengan Process Variable (PV); Sinyal output DCS (misal 80%) tidak sama dengan feedback posisi valve (misal diam di 20%). Cek suplai udara instrumen ke control valve. Cek status I/P Converter; Minta operator lokal memutar handwheel (jika ada) atau lakukan forcing sinyal saat kondisi aman. Alarm "Control Valve Deviation" di DCS; Jalur Emergency Drain dengan kontroler dan katup terpisah Lakukan tes diagnostik Valve Signature menggunakan smart positioner saat outage untuk mendeteksi gesekan (friction) atau histeresis; Pastikan kualitas udara instrumen kering dan bersih (bebas oli/air) agar positioner tidak macet. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Menahan tekanan fluida pada sisi tube 232 bar(g) dan sisi shell 21.3 bar(g) Tekanan Desain Sisi Tube: 232.0 bar(g); Tekanan Desain Sisi Shell: 21.3 bar(g); Suhu Desain Sisi Shell: 218 C (Inlet Steam: 488 C) Gagal menahan tekanan fluida pada sisi tube pada 232 bar(g) dan shell pada 21.3 bar(g) DCS High Pressure Alarm Setpoint Parameter deviation Out of adjustment Jika setting terlalu rendah: Relief Valve membuka di bawah tekanan desain (misal: desain 21.3 bar, membuka di 19 bar), Menyebabkan kebocoran eksternal uap terus-menerus (simmering/passing); Jika setting terlalu tinggi: Saat terjadi insiden (misal: tube rupture), valve tidak membuka pada tekanan 21.3 bar. Tekanan shell bisa melampaui Maximum Allowable Working Pressure (MAWP), berisiko ledakan fisik shell. Audible (Low Set): Suara mendesis di pipa buang safety valve saat operasi normal beban penuh; Temperature (Low Set): Pipa buang safety valve terasa panas jauh ke arah hilir (indikasi bocor); High Set: Tidak ada indikasi sampai terjadi kegagalan proteksi saat insiden. Lakukan tes in-situ (Trevitest) untuk memverifikasi set pressure aktual tanpa melepas valve; Lepas valve dan tes di meja kalibrasi (test bench). Aturan Migas/Disnaker mewajibkan sertifikasi ulang Safety Valve secara berkala (biasanya tahunan); Baut penyetel safety valve disegel timah untuk mencegah pengubahan sembarangan. Patuhi jadwal kalibrasi Safety Valve sisi Shell secara ketat. Jangan pernah menaikkan setting di atas spesifikasi manual (21.3 bar + toleransi standar); Pastikan segel pengaman pada adjusting ring dan spring masih utuh saat inspeksi rutin. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Menahan tekanan fluida pada sisi tube 232 bar(g) dan sisi shell 21.3 bar(g) Tekanan Desain Sisi Tube: 232.0 bar(g); Tekanan Desain Sisi Shell: 21.3 bar(g); Suhu Desain Sisi Shell: 218 C (Inlet Steam: 488 C) Gagal menahan tekanan fluida pada sisi tube pada 232 bar(g) dan shell pada 21.3 bar(g) Shell Safety Relief Valve (SRV) Inlet/Outlet Piping Plugged/Choked Blockage/plugged Tekanan shell naik tajam. Jika Safety Valve tidak mampu membuang fase air (karena didesain untuk fase uap), shell bisa mengalami deformasi plastik (menggelembung) atau pecah; Risiko air masuk kembali ke turbin (Water Induction) melalui jalur ekstraksi uap jika proteksi isolasi gagal;Trip Unit atau Load Runback karena kehilangan satu heater regeneratif secara mendadak. Indikasi level HPH 5 "High" kemudian "High-High" dalam waktu singkat; Drain Control Valve terbaca membuka 100% pada DCS, namun level tidak turun; Tekanan shell terbaca lebih tinggi dari tekanan saturasi normal pada beban tersebut. Buka katup bypass drain (jika ada) secara manual di lokal. Jika aliran lancar dan level turun, berarti sumbatan ada di jalur utama (control valve atau strainer); Dengarkan suara aliran di pipa drain. Jika valve 100% tapi hening, berarti tidak ada aliran (total blockage). Trip HHWL (High-High Water Level) akan menutup Extraction Steam MOV dan Non-Return Valve untuk menghentikan suplai uap; Jalur Emergency Drain (ke Kondensor) akan membuka otomatis jika jalur Normal Drain tersumbat. Lakukan inspeksi dan pembersihan rutin pada strainer (saringan) jalur drain, terutama setelah maintenance outage; Pastikan logika pembukaan Emergency Drain bersifat independen dari pemancar level yang sama (gunakan Level Switch terpisah untuk redundansi). +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Menahan tekanan fluida pada sisi tube 232 bar(g) dan sisi shell 21.3 bar(g) Tekanan Desain Sisi Tube: 232.0 bar(g); Tekanan Desain Sisi Shell: 21.3 bar(g); Suhu Desain Sisi Shell: 218 C (Inlet Steam: 488 C) Gagal menahan tekanan fluida pada sisi tube pada 232 bar(g) dan shell pada 21.3 bar(g) Shell Body Plate Structural deficiency Corrosion Penipisan dinding (thinning) di bawah batas minimum yang diizinkan (Minimum Allowable Thickness). Terbentuknya pitting (lubang jarum) yang dalam; Penurunan Rating Tekanan Aman: Bejana tidak lagi memenuhi kode ASME/standar bejana tekan untuk operasi 21 bar (shell) atau 232 bar (water box); Risiko pecah mendadak (burst) jika terjadi lonjakan tekanan transien, karena material sudah terlalu tipis untuk menahan tegangan hoop stress. Tampak noda karat pada cladding isolasi (indikasi rembesan uap dari pinhole); Tren hasil pengukuran ketebalan (UT Thickness Monitoring) menunjukkan grafik penurunan yang curam dari tahun ke tahun. Lakukan pemetaan ketebalan ultrasonik (Ultrasonic Thickness Mapping) dengan sistem grid rapat pada area yang dicurigai; Masuk ke dalam shell saat overhaul untuk melihat tingkat pengelupasan karat (scaling). Desain awal menambahkan ketebalan ekstra (misal +3mm atau +6mm) di atas ketebalan kalkulasi beban sebagai toleransi korosi; Prosedur Nitrogen Capping (selimut gas N2) atau Wet Lay-up dengan Hydrazine saat unit mati untuk mencegah kontak dengan O2. Lakukan perhitungan sisa umur pakai berdasarkan laju korosi aktual. Jika ketebalan mendekati batas minimum, turunkan tekanan operasi (derating) atau rencanakan penggantian shell; Pertimbangkan aplikasi pelapis anti-korosi termal (thermal spray aluminium) pada permukaan dalam shell saat perbaikan besar, jika material memungkinkan. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Menahan tekanan fluida pada sisi tube 232 bar(g) dan sisi shell 21.3 bar(g) Tekanan Desain Sisi Tube: 232.0 bar(g); Tekanan Desain Sisi Shell: 21.3 bar(g); Suhu Desain Sisi Shell: 218 C (Inlet Steam: 488 C) Gagal menahan tekanan fluida pada sisi tube pada 232 bar(g) dan shell pada 21.3 bar(g) Shell Girth Welds Structural deficiency Mechanical failure-general Inisiasi retakan mikro (micro-cracking) pada area konsentrasi tegangan (sudut radius, sambungan las nozel inlet); Brittle Fracture (Pecah Getas): Jika HPH 5 ditekan tinggi saat suhu logam masih dingin (di bawah suhu transisi), retakan ini bisa merambat dengan kecepatan suara, menyebabkan water box pecah berkeping-keping; Leakage: Retakan menembus dinding, menyebabkan kebocoran yang sulit ditambal (crack propagation). Seringkali tidak ada gejala operasional sampai terjadi kebocoran atau pecah; Rembesan air yang keluar dari balik isolasi di area leher nozel atau keliling head. Wajib melakukan Magnetic Particle Test (MT) atau Phased Array Ultrasonic Test (PAUT) pada area radius tube sheet dan lasan nozel setiap kali overhaul besar (Inspection Grade 1). HPH 5 menggunakan desain Water Box setengah bola untuk distribusi tegangan yang lebih merata dibanding tipe flat head; Berdasarkan operating procedure, kurva pemanasan/pendinginan dibatasi (maks 200 C/jam) untuk meminimalkan thermal shock. Jika ditemukan retak dangkal, gerinda (grinding) hingga dasar retakan hilang. Lakukan pengelasan ulang dengan prosedur pre-heat dan post-weld heat treatment (PWHT) yang ketat; Perbesar radius kelengkungan (fillet radius) pada sudut-sudut tajam dengan gerinda untuk mengurangi faktor konsentrasi tegangan +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Menahan tekanan fluida pada sisi tube 232 bar(g) dan sisi shell 21.3 bar(g) Tekanan Desain Sisi Tube: 232.0 bar(g); Tekanan Desain Sisi Shell: 21.3 bar(g); Suhu Desain Sisi Shell: 218 C (Inlet Steam: 488 C) Gagal menahan tekanan fluida pada sisi tube pada 232 bar(g) dan shell pada 21.3 bar(g) Tube Support Baffle Holes Structural deficiency Wear Penipisan dinding lokal (localized thinning) yang ekstrem. Dinding bisa menjadi setipis kertas di area seluas telapak tangan, sementara area lain masih tebal; Dinding yang tipis tiba-tiba robek saat operasi normal, melepaskan uap panas ke area kerja; Kerusakan komponen internal lain (pelat partisi, penyangga tube) akibat turbulensi aliran yang berubah karena profil dinding yang rusak. Deteksi termografi menunjukkan satu titik panas yang tidak wajar pada dinding luar shell (dekat inlet); Suara bising aliran turbulen yang meningkat seiring waktu pada area tertentu. Inspeksi visual langsung adalah cara terbaik. Cari area yang permukaannya tampak "hanyut" atau mengkilap akibat erosi; Lakukan scanning ketebalan ultrasonik secara menyeluruh di sekitar nozzle inlet (zona jam 12, 3, 6, 9 dari nozel). Pelat Stainless Steel dipasang di depan nozel masuk untuk menerima hantaman utama uap; Pada beberapa desain, area shell di sekitar inlet dilapisi pelat pelindung. Jika Impingement Plate ditemukan rusak/lepas saat inspeksi, segera perbaiki atau ganti dengan material yang lebih tebal/tahan erosi; Jika dinding shell sudah tererosi, pasang pelat penambal (doubler plate) dari luar atau lakukan weld build-up dari dalam untuk mengembalikan ketebalan, sesuai standar ASME PCC-2 (Repair of Pressure Equipment). +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Menahan tekanan fluida pada sisi tube 232 bar(g) dan sisi shell 21.3 bar(g) Tekanan Desain Sisi Tube: 232.0 bar(g); Tekanan Desain Sisi Shell: 21.3 bar(g); Suhu Desain Sisi Shell: 218 C (Inlet Steam: 488 C) Gagal menahan tekanan fluida pada sisi tube pada 232 bar(g) dan shell pada 21.3 bar(g) Outer Row U-Tubes, Impingement Plate Tube Vibration High steam velocity on shell side Terjadi fatigue cracking pada dinding tube atau sambungan las tube-to-tubesheet; Kebocoran internal masif (Tube Rupture). Air 232 bar menyembur ke shell 21 bar; Lonjakan tekanan shell mendadak yang menguji keandalan Safety Valve (3FW-SFV003). Risiko deformasi shell jika relief valve lambat. Suara bising (rumbling) di area inlet uap; Fluktuasi level air yang tidak stabil (unstable level control) pada beban tinggi karena turbulensi internal. Pasang akselerometer pada dinding shell dekat nozel inlet saat operasi untuk mendeteksi frekuensi getaran dominan; Cek apakah aliran uap ekstraksi melebihi desain (114,900 kg/h) saat kejadian bising. Pelat pelindung dipasang di inlet nozzle untuk memecah energi uap sebelum mengenai tube; Orifice 32.9 mm dipasang pada partisi untuk menyeimbangkan aliran bypass akibat plugging, mencegah lonjakan kecepatan tak terkendali. Saat overhaul, cek kondisi Impingement Plate. Jika lepas atau berlubang, uap kecepatan tinggi akan langsung menghantam tube; Saat inspeksi kebocoran, perhatikan apakah tube yang bocor berada di area perimeter (pinggir). Jika ya, konfirmasi masalah kecepatan uap inlet. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Menahan tekanan fluida pada sisi tube 232 bar(g) dan sisi shell 21.3 bar(g) Tekanan Desain Sisi Tube: 232.0 bar(g); Tekanan Desain Sisi Shell: 21.3 bar(g); Suhu Desain Sisi Shell: 218 C (Inlet Steam: 488 C) Gagal menahan tekanan fluida pada sisi tube pada 232 bar(g) dan shell pada 21.3 bar(g) U-Tubes, Baffle Plates. Tube Vibration Baffle gap is too far Getaran aliran normal menyebabkan tube beradu dengan dinding lubang support plate. Dinding tube menipis tepat di lokasi penyangga; Penipisan dinding menyebabkan tube tidak kuat menahan tekanan internal 232 bar sehingga menyebabkan pecah (burst). Sangat sulit dideteksi saat operasi karena getarannya bersifat lokal (teredam di dalam); Kenaikan laju bukaan drain valve secara bertahap (kebocoran kecil akibat aus sebelum pecah). Lakukan Eddy Current Test (ECT). Sinyal ECT akan menunjukkan cacat (defect) atau penipisan dinding yang bertepatan persis dengan lokasi support plate; Jika retubing Tarik tube keluar dan lihat pola cincin aus (ring wear) pada permukaan luar tube. Toleransi celah tube-baffle diatur ketat (biasanya maks 0.4 - 0.8 mm); Jarak antar baffle dihitung untuk mencegah sagging (lendutan). Jika ECT mengonfirmasi kelonggaran, pasang pasak (tube stakes) di antara celah tube untuk mengunci tube secara mekanis agar tidak bergerak, tanpa perlu menyumbat (plug) tube tersebut (sehingga efisiensi tetap terjaga). +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Menahan tekanan fluida pada sisi tube 232 bar(g) dan sisi shell 21.3 bar(g) Tekanan Desain Sisi Tube: 232.0 bar(g); Tekanan Desain Sisi Shell: 21.3 bar(g); Suhu Desain Sisi Shell: 218 C (Inlet Steam: 488 C) Gagal menahan tekanan fluida pada sisi tube pada 232 bar(g) dan shell pada 21.3 bar(g) U-Tubes Tube Vibration Fluidelastic whirring or vortex shedding Tube bergetar hebat hingga menabrak tube tetangganya (tube-to-tube collision). Pola kerusakan biasanya berbentuk irisan datar (flat spots) di tengah bentang tube; Hilangnya penahanan tekanan secara instan. Risiko masuknya air ke turbin sangat tinggi karena volume kebocoran sangat besar. Suara dengungan keras atau siulan nyaring dari dalam heater yang terdengar jelas di luar isolasi. Frekuensi suara berubah seiring beban. Rekam suara dan analisis frekuensinya; Saat shutdown, lihat ke dalam bundle (jika bisa) untuk mencari tube yang saling bersentuhan atau tanda gesekan antar tube. Desainer menghitung jarak penyangga agar frekuensi natural tube jauh di atas frekuensi eksitasi uap. Jika getaran terjadi pada beban 100%, batasi beban unit (misal maks 90%) sampai perbaikan bisa dilakukan; Pasang batangan penyisip (anti-vibration bars/clips) di area U-bend atau area lurus yang mengalami getaran untuk mengubah frekuensi natural tube. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Menahan tekanan fluida pada sisi tube 232 bar(g) dan sisi shell 21.3 bar(g) Tekanan Desain Sisi Tube: 232.0 bar(g); Tekanan Desain Sisi Shell: 21.3 bar(g); Suhu Desain Sisi Shell: 218 C (Inlet Steam: 488 C) Gagal menahan tekanan fluida pada sisi tube pada 232 bar(g) dan shell pada 21.3 bar(g) Tube-to-Tubesheet Weld Joints Tube Vibration Abnormal operation Perubahan densitas fluida yang cepat menyebabkan guncangan hidrolik (hydraulic shock); Jika HPH 6/7 bypass, HPH 5 menerima beban uap ekstraksi jauh melebihi desain; Kelelahan siklus rendah (low cycle fatigue) pada tube sheet ligament. Retak bisa terjadi pada struktur penahan tekanan utama. Getaran hanya muncul saat ramp-up beban atau saat manuver bypass heater; Alarm "Rate of Change High" pada temperatur feed water Kroscek waktu terjadinya kebocoran/kerusakan tube dengan log operasi abnormal (misal: paska trip unit atau operasi beban puncak dengan satu heater out). Instruction Manual TJB membatasi laju perubahan suhu feed water maks 200 C/jam; Interlock yang mencegah operasi HPH jika parameter tidak masuk akal. Dilarang keras memaksakan HPH 5 beroperasi di atas kapasitas desain saat HPH lain rusak. Lebih baik turunkan beban unit (MW) daripada mengorbankan HPH 5; Pastikan katup uap ekstraksi dibuka secara bertahap (throttling) saat start-up untuk menghindari hantaman uap mendadak (steam hammer) ke tube. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Menahan tekanan fluida pada sisi tube 232 bar(g) dan sisi shell 21.3 bar(g) Tekanan Desain Sisi Tube: 232.0 bar(g); Tekanan Desain Sisi Shell: 21.3 bar(g); Suhu Desain Sisi Shell: 218 C (Inlet Steam: 488 C) Gagal menahan tekanan fluida pada sisi tube pada 232 bar(g) dan shell pada 21.3 bar(g) Subcooler U-Tubes, Drain Control Valve (DCV) Flashing at Subcooler Poor water level control Terjadi erosi kavitasi dan getaran tube frekuensi tinggi di zona subcooler; Saat tube pecah, feed water 232 bar menyembur ke shell 21 bar, menyebabkan lonjakan tekanan shell (overpressure); Kerusakan pada pipa drainase menuju Deaerator akibat aliran dua fase (uap-air) yang menyebabkan pipe hammering; Gangguan pada Deaerator (tujuan drain HPH 5) akibat masuknya uap tak terkondensasi. Indikasi level di DCS sering "Low" atau berfluktuasi tajam (hunting); Suara gemuruh atau pukulan palu (hammering) pada badan heater bagian bawah atau pipa drain; emperatur drain outlet naik drastis mendekati temperatur saturasi uap, artinya DCA (Drain Cooler Approach) melebar. Bandingkan pembacaan Transmitter di DCS dengan Local Sight Glass. Pastikan transmitter tidak mengalami drift; Hitung selisih suhu drain keluar dikurangi suhu feed water masuk. Jika DCA =~0 atau sangat kecil (mendekati saturasi), berarti uap masuk ke drain cooler. Alarm "Heater Level Low" dan "Heater Level High"; Kontroler PID mengatur Drain Control Valve untuk menjaga Normal Water Level (NWL) tetap di atas inlet subcooler. Pastikan parameter PID (Gain/Reset) pada kontroler level disetel agar responsif namun stabil. Level tidak boleh undershoot (turun di bawah setpoint) saat perubahan beban turbin; Verifikasi bahwa setpoint NWL di DCS benar-benar berada di atas bibir inlet subcooler wrapper. Naikkan setpoint sedikit (+20-50mm) jika ragu, untuk menjamin water seal yang lebih aman, meskipun sedikit mengorbankan efisiensi termal. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Menahan tekanan fluida pada sisi tube 232 bar(g) dan sisi shell 21.3 bar(g) Tekanan Desain Sisi Tube: 232.0 bar(g); Tekanan Desain Sisi Shell: 21.3 bar(g); Suhu Desain Sisi Shell: 218 C (Inlet Steam: 488 C) Gagal menahan tekanan fluida pada sisi tube pada 232 bar(g) dan shell pada 21.3 bar(g) Subcooler Shroud Welds, Subcooler U-Tubes Flashing at Subcooler Shroud or end plate leakage abung di sekitar kebocoran shroud akan tergerus parah (localized erosion) hingga dindingnya habis dan bocor; Kebocoran internal yang berkembang cepat dari kecil menjadi besar; Penurunan efisiensi HPH secara permanen (karena bypass panas). Gejala paling khas adalah nilai DCA (Drain Cooler Approach) Tinggi. Suhu drain keluar lebih panas dari desain (5.6 C) meskipun level air normal. Hal ini karena drain tercampur uap panas yang bocor lewat shroud. Pantau tren DCA harian. Jika DCA naik bertahap tanpa perubahan beban yang signifikan, curigai kebocoran internal shroud; Saat inspeksi, pola penipisan dinding tube akan terlihat spesifik hanya pada tube-tube di pinggiran zona subcooler atau dekat end plate, bukan acak. Construction menggunakan konstruksi las penuh (continuous fillet weld) pada shroud untuk kekedapan; Pelat selubung biasanya lebih tebal untuk menahan beda tekanan. Saat overhaul, lakukan inspeksi visual (jika akses memungkinkan) atau boroscope untuk melihat kondisi lasan shroud; Jika kebocoran teridentifikasi, lakukan pengelasan ulang (repair welding) pada shroud yang retak; Jika kerusakan tube akibat kebocoran shroud berulang, pertimbangkan memasang tube pasak (dummy tubes) atau pelat pelindung tambahan di area yang rentan erosi tersebut. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Mendinginkan kondensat (drain) hingga 175.9 C sebelum dibuang untuk efisiensi termal. Drain Cooler Approach (DCA): 5.60 C; Laju Alir Drain: 434,412 kg/h; Suhu Outlet Drain: 175.9 C; Tujuan Pembuangan: Ke Deaerator. Gagal mendinginkan kondensat hingga 175.9 C Drain Control Valve (DCV) Actuator, DCS Level Controller (PID Logic). Abnormal instrument reading Control failure Jika kontroler gagal dan memerintahkan Drain Valve membuka terlalu besar (overshoot), level air di dalam heater akan turun drastis di bawah bibir inlet Drain Cooling Zone; Suhu drain menuju Deaerator menjadi sangat panas (mendekati suhu saturasi). Energi uap yang lolos ini dapat merusak internal tray Deaerator dan menyebabkan getaran pipa drain. Nilai DCA melonjak tinggi; Bukaan Control Valve tidak stabil (hunting) atau membeku di posisi terbuka lebar. Cek sinyal output (MV) dari kontroler di DCS vs respons posisi aktual valve di lapangan; Ubah kontroler ke mode Manual. Jika level bisa distabilkan dan DCA turun kembali normal, berarti masalah ada pada parameter tuning otomatis. Alarm "Drain Cooler Approach High" (biasanya calculated tag di DCS); Proteksi level rendah (Low Level) mungkin akan menutup valve secara paksa (override) untuk mengembalikan segel air. Lakukan fine-tuning parameter PID agar kontroler tidak agresif (terlalu cepat membuka valve) saat terjadi gangguan beban kecil. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Mendinginkan kondensat (drain) hingga 175.9 C sebelum dibuang untuk efisiensi termal.

Gagal mendinginkan kondensat hingga 175.9 C Level Transmitter Sensing Line Abnormal instrument reading Corrosion Jika jalur High Pressure side (bawah) pada transmitter DP tersumbat lumpur karat, pembacaan level bisa tertahan tinggi (stuck high); evel aktual di dalam shell menjadi sangat rendah (kering). Zona drain cooling terekspos uap panas. Fungsi pendinginan gagal total. Level di DCS menunjukkan "Normal" atau "High", tetapi DCA menunjukkan nilai yang sangat buruk (Panas); Grafik level terlihat rata atau sangat lambat bereaksi. Lakukan flushing/blowdown pada sensing line instrumen level. Perhatikan warna air yang keluar (hitam/coklat menandakan korosi); Bandingkan level DCS dengan level gauge lokal. Pipa impuls biasanya Stainless Steel, namun koneksi ke bejana Carbon Steel tetap rawan korosi. Jadwalkan blowdown instrumen level HPH secara rutin; Cek kondisi root valve di dinding shell saat shutdown, pastikan tidak buntu total. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Mendinginkan kondensat (drain) hingga 175.9 C sebelum dibuang untuk efisiensi termal.

Gagal mendinginkan kondensat hingga 175.9 C Drain Temperature Sensor (RTD/Thermocouple). Abnormal instrument reading Faulty signal/indication/alarm Kesalahan pembacaan suhu inlet/outlet feed water atau suhu drain; Jika sinyal level yang drift (misal: geser 10%), HPH beroperasi pada level yang "tanggung". Pendinginan tidak optimal karena area perpindahan panas efektif berkurang. Membandingkan suhu drain HPH 5 dengan suhu air di pipa masuk Deaerator (seharusnya mirip, hanya beda sedikit heat loss di pipa). Jika beda jauh, sensor HPH mungkin drift. Membandingkan suhu drain HPH 5 dengan suhu air di pipa masuk Deaerator (seharusnya mirip, hanya beda sedikit heat loss di pipa). Jika beda jauh, sensor HPH mungkin drift. Biasanya sensor suhu dipasang ganda (A/B). Kalibrasi sensor suhu drain outlet dan sensor level setiap outage. Akurasi sensor suhu krusial untuk perhitungan performa. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Mendinginkan kondensat (drain) hingga 175.9 C sebelum dibuang untuk efisiensi termal.

Level air tidak lagi dijaga otomatis. Tampilan "Bad Quality", "I/O Error", atau nilai out of range (misal -25% atau 125%). Cek status diagnostik transmitter menggunakan komunikator HART; Cek tegangan suplai 24VDC. Logika kontrol didesain agar Control Valve tertahan di posisi terakhir (Fail-Lock) atau menutup perlahan jika sinyal hilang, untuk mencegah pembuangan air mendadak. Sediakan cadangan transmitter level tipe DP dan RTD. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Mendinginkan kondensat (drain) hingga 175.9 C sebelum dibuang untuk efisiensi termal.

Aliran kondensat di dalam zona pendingin menjadi turbulen dan tidak stabil. Efisiensi pertukaran panas drop. Grafik level seperti "rumput" (banyak noise vertikal); Suara "cetak-cetok" pada valve drain akibat perintah yang berubah cepat. Ketuk pelan housing transmitter atau goyangkan kabel. Jika sinyal di DCS melompat, ada koneksi kendor. Filter waktu pada input DCS. Kencangkan semua terminasi kabel instrumen di area HPH yang bergetar. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Mendinginkan kondensat (drain) hingga 175.9 C sebelum dibuang untuk efisiensi termal.

Abnormal instrument reading No signal/indication/alarm Sama dengan instrument failure, operator buta posisi level; Fungsi pendinginan drain tidak terkontrol. Jika katup drain tertutup karena hilang sinyal, level akan naik sampai banjir (pendinginan drain gagal karena terendam banjir). Jika terbuka, uap lolos. Alarm "Loop Open" atau "Sensor Break". Cek kontinuitas loop. Alarm HHWL dari switch independen (biasanya beda kabel) akan tetap melindungi turbin meski transmitter analog putus. Pastikan kabel instrumen di jalur tray yang aman dari injakan kaki atau pekerjaan las. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Mendinginkan kondensat (drain) hingga 175.9 C sebelum dibuang untuk efisiensi termal.

Gagal mendinginkan kondensat hingga 175.9 C DCS Level Setpoint Parameter Abnormal instrument reading Out of adjustment Jika terjadi Zero shift, maka akan berakibat uap selalu lolos ke subcooler meskipun operator mengira level aman. Pendinginan gagal permanen; Operator menurunkan Setpoint level terlalu rendah (misal untuk mengurangi TTD), tanpa sadar bahwa level tersebut sudah membahayakan segel air (water seal). Masalah pendinginan (DCA tinggi) yang persisten/kronis meskipun instrumen terlihat "sehat" dan stabil. Lakukan kalibrasi basah (wet leg calibration) pada transmitter DP untuk memastikan perhitungan Specific Gravity dan elevasi nol sudah tepat sesuai densitas air panas (170 C) Dokumen datasheet instrumen memuat elevasi tap dan setting range. Verifikasi elevasi fisik nozzle instrumen level terhadap gambar General Arrangement (GA) heater. Pastikan 0% level di DCS = Minimal 50-100mm di atas Inlet Subcooler Enclosure; Berikan batasan Hard Limit pada DCS agar operator tidak bisa menurunkan setpoint level di bawah batas aman water seal. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Mendinginkan kondensat (drain) hingga 175.9 C sebelum dibuang untuk efisiensi termal.

External leakage-Process medium Mechanical failure-general Kebocoran masif yang tidak bisa diisolasi hanya dengan menutup valve (seringkali butuh waktu untuk depressurisasi); Kehilangan total fungsi HPH 5 dalam jangka panjang (bulan) untuk perbaikan las atau penggantian shell/head; Selama masa perbaikan, unit beroperasi dengan efisiensi rendah (tanpa pendinginan drain HPH 5). Air keluar dari celah isolasi di area yang tidak ada sambungan flange (misal: leher nozel atau dinding head). Dye Penetrant (PT) atau Magnetic Particle (MT) untuk mencari lokasi retakan. Pengujian tekanan hidrostatis 1.5x tekanan desain saat manufaktur dan perbaikan besar; Baja tempa (Forging) kualitas tinggi (SA-266 atau setara) untuk Water Box guna ketahanan impak. Lakukan prosedur perbaikan las (Weld Repair Procedure) yang disetujui Authorized Inspector, termasuk Pre-heat dan Post-Weld Heat Treatment (PWHT) untuk menghilangkan tegangan sisa; Jika terjadi retak, wajib investigasi apakah akibat siklus termal (thermal shock) atau cacat material. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Mendinginkan kondensat (drain) hingga 175.9 C sebelum dibuang untuk efisiensi termal.

External leakage-Utility medium Leakage Erosi pada permukaan flange (wire drawing) akibat kecepatan uap bocor yang tinggi. Kerusakan isolasi termal; ika kebocoran besar, HPH 5 harus diisolasi (Cut-out); Kondensat panas terbuang ke lingkungan atau harus dialihkan ke Emergency Drain (Kondensor), membuang energi panas yang seharusnya masuk ke Deaerator. Semburan uap atau air panas dari bawah isolasi di area bawah heater (dekat outlet drain). Lantai basah/banjir air panas; Suara mendesis (hissing) atau gemuruh aliran dua fase; Mungkin terjadi penurunan level air di shell yang sulit dikompensasi oleh control valve; Perbedaan aliran (flow mismatch) antara calculated condensate flow dan aktual (jika ada flowmeter). Cek area sambungan flange pipa drain, bonnet control valve drain, dan drain boss di dinding shell; Tutup sementara katup isolasi drain (jika ada bypass) untuk melihat apakah desisan berhenti. Pipa drain menggunakan material Carbon Steel jadwal tebal (Sch 80 atau lebih) untuk menahan erosi aliran dua fase; Menggunakan gasket tahan panas (Spiral wound with graphite filler); Pipa drain didesain dengan loop fleksibilitas untuk menyerap ekspansi termal dan mencegah beban berlebih pada nozel heater. Jika kebocoran sering terjadi pada lasan/flange pipa drain, lakukan evaluasi pipe support; Kencangkan atau ganti packing pada Drain Control Valve dan katup isolasi secara rutin; Pastikan isolasi pada pipa drain dalam kondisi baik. Kebocoran kecil yang tertutup isolasi basah dapat menyebabkan CUI (Corrosion Under Insulation) yang memperparah kebocoran di kemudian hari. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Mendinginkan kondensat (drain) hingga 175.9 C sebelum dibuang untuk efisiensi termal.

Aliran drain terganggu oleh semburan feed water; Level air naik instan menuju HHWL; Trip HPH 5. Dentuman keras dari bagian bawah heater; Alarm "Heater Level High-High" muncul sangat cepat; Data DCA menjadi acak/tidak valid sesaat sebelum trip. Lakukan hydrotest. Air akan memancar sangat deras dari drain outlet atau shell drain; Masukkan kamera inspeksi lewat nozel drain (jika memungkinkan) untuk melihat apakah ada puing-puing baffle yang rontok. Selubung DCZ biasanya dirancang lebih tebal dari partisi lain; Trip HHWL untuk menghentikan suplai feed water Saat perbaikan, pastikan seluruh pecahan tube dan baffle dikeluarkan dari shell. Puing tertinggal akan menyebabkan kerusakan berulang; Pasang plug pada kedua ujung tube patah dan pasang rod stabilizer di dalamnya agar tidak mencambuk tube lain. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Mendinginkan kondensat (drain) hingga 175.9 C sebelum dibuang untuk efisiensi termal.

Gagal mendinginkan kondensat hingga 175.9 C U-Tubes (Tube Bundle), Tube-to-Tubesheet Weld Joints. Internal leakage Burst Satu tube pecah di DCZ sering menyebabkan 3-4 tube di sekitarnya ikut bocor parah karena terpotong semburan air (impingement); DCA melebar drastis (>10-15 C) karena pola aliran pendinginan (zigzag) rusak total. Kondensat panas langsung "terdorong" keluar oleh air bocoran; Kenaikan bukaan Drain Control Valve yang progresif dan cepat. Grafik bukaan drain valve naik tajam (misal dari 50% ke 80% dalam 1 jam); DCA memburuk (naik) secara signifikan bersamaan dengan kenaikan level drain. Eddy Current Test (ECT) wajib. Cek tidak hanya tube yang bocor, tapi "Area Kerusakan" di sekitarnya (blast zone); Tes udara bertekanan untuk melokalisir area kebocoran (biasanya terdengar suara mendesis keras dari dalam wrapper DCZ). Jarak baffle di DCZ dibuat lebih rapat untuk mencegah getaran. Sumbat (plug) semua tube di radius 2 baris dari tube yang pecah (burst) sebagai tindakan pencegahan, karena tube-tube tersebut kemungkinan besar sudah mengalami penipisan akibat impingement. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Mendinginkan kondensat (drain) hingga 175.9 C sebelum dibuang untuk efisiensi termal.

Aliran kondensat yang seharusnya laminar di sekitar tube menjadi turbulen; Efisiensi perpindahan panas turun perlahan; Erosi jangka panjang (wire drawing) pada lubang bocor yang perlahan membesar. Sulit dideteksi. Indikasi awal hanyalah DCA yang sedikit di atas normal dan bukaan drain valve yang sedikit lebih besar dari biasanya. Saat unit mati, vakum sisi shell. Kebocoran kecil akan menyebabkan vakum cepat hilang; Masukkan zat pewarna (Fluorescein) ke sisi air saat tes hidrostatik untuk melihat rembesan yang keluar dari drain outlet. Pantauan rutin efisiensi DCA oleh Performance Engineer. Jika kebocoran terjadi di area lurus dekat inlet DCZ (area yang bisa dijangkau), pertimbangkan pemasangan internal sleeve untuk menutup bocor tanpa mematikan tube, guna mempertahankan luas permukaan pendinginan. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Mendinginkan kondensat (drain) hingga 175.9 C sebelum dibuang untuk efisiensi termal.

Tube menjadi tipis di titik tumpuan baffle; Kebocoran berulang pada lokasi yang sama (misal: selalu di baris tube paling bawah atau area "jendela" baffle). Umur tube bundle memendek drastis. Suara gemeretak atau dengungan dari area DCZ saat beban tinggi; Nilai DCA berfluktuasi seiring perubahan beban (karena amplitudo getaran berubah). Saat inspeksi ECT, petakan lokasi kerusakan. Jika kerusakan membentuk pola garis atau blok tertentu di DCZ, penyebabnya adalah vibrasi sistemik, bukan korosi acak; Tarik satu tube yang rusak (pull out) untuk melihat bekas gesekan (wear scar) pada dinding luar. Baffle biasanya menggunakan material yang lebih lunak dari tube atau lubang yang di-chamfer untuk mengurangi gesekan. Pasang pasak anti-vibrasi (tube stakes) di sela-sela tube DCZ yang bisa dijangkau; Jika getaran parah, evaluasi apakah perlu mengubah ukuran orifice pada partisi (32.9 mm) untuk mengubah karakteristik aliran di dalam heater. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Mendinginkan kondensat (drain) hingga 175.9 C sebelum dibuang untuk efisiensi termal.

Kondensat keluar dari HPH 5 dengan suhu yang jauh lebih tinggi dari desain (176 C); Nilai DCA naik signifikan; Panas yang seharusnya diserap kembali oleh feed water malah terbawa ke Deaerator; Jika sumbatan parah di inlet subcooler, level air di zona kondensasi akan naik (banjir) karena drain tidak bisa turun ke zona pendingin dengan lancar. DCA Tinggi secara konsisten; Mungkin terjadi kenaikan level air di shell yang memaksa drain valve membuka lebih lebar dari biasanya (jika sumbatan menghambat aliran). Cek tren kenaikan DCA selama 1-3 bulan terakhir. Kenaikan bertahap (gradual) menandakan fouling, kenaikan mendadak (step change) menandakan blockage fisik; Cek selisih tekanan feed water. Fouling biasanya juga menaikkan delta P sisi feed water Parameter DCA dipantau di DCS; Kontrol kimia air untuk meminimalkan pembentukan kerak/fouling. Lakukan pembersihan tube (Bullet Cleaning atau High Pressure Jetting) saat overhaul untuk menghilangkan fouling; Inspeksi visual area inlet subcooler saat shutdown untuk memastikan tidak ada benda asing (sisa gasket/las) yang menutupi jalur masuk. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Mendinginkan kondensat (drain) hingga 175.9 C sebelum dibuang untuk efisiensi termal.

Siklus panas-dingin ini menyebabkan thermal fatigue pada tube; Pendinginan menjadi tidak stabil. Rata-rata suhu drain outlet menjadi lebih tinggi karena periode "steam ingestion"; Gangguan aliran drain ke Deaerator (berdenyut/pulsating flow) yang mengganggu kontrol level Deaerator. Grafik level di DCS membentuk gelombang sinus yang konsisten; Drain Control Valve terus bergerak buka-tutup dengan frekuensi tetap; Nilai DCA berfluktuasi. Ubah mode kontroler ke MANUAL. Setel bukaan valve tetap. Jika level menjadi stabil (tidak naik/turun sendiri), berarti masalahnya murni pada tuning parameter kontroler, bukan proses. Menggunakan algoritma PID standar. Lakukan loop tuning ulang.

Fungsi pendinginan di-bypass total atau parsial; Ketika Setpoint Low, menyebabkan hilangnya water seal. Uap masuk ke zona pendingin, menyebabkan DCA naik (panas) dan vibrasi. Pipa drain di hilir katup bypass terasa sangat panas/bergetar; Setpoint di DCS terlihat rendah (misal -100mm dari Normal). Cek posisi fisik handwheel katup bypass manual (harus tertutup rapat); Bandingkan nilai Setpoint (SP) level saat ini dengan nilai pada Datasheet Operasi atau P&ID.

Structural deficiency Corrosion Terjadi Short Circuit (Jalan Pintas). Kondensat panas dari shell masuk ke zona pendingin melalui lubang korosi tersebut (bukan lewat inlet normal), memotong jalur pendinginan yang seharusnya panjang (zigzag). Akibatnya, waktu kontak dengan tube berkurang; Nilai DCA merangkak naik perlahan seiring membesarnya lubang korosi. Efisiensi HPH turun (DCA melebar) secara bertahap dalam kurun waktu lama (tahunan); Peningkatan kadar partikel besi pada sampel air drain. Wajib masuk ke dalam shell saat Major Overhaul.

Structural deficiency Mechanical failure-general Celah retakan terbuka pada sambungan las; Karena perbedaan tekanan (Shell side lebih tinggi sedikit dari dalam DCZ karena pressure drop baffle), kondensat atau uap akan menyemprot masuk lewat retakan; Semburan ini bertindak sebagai pisau air/uap yang memotong tube di dekat lasan yang retak. Ini adalah penyebab umum kebocoran tube di area subcooler inlet; DCA tinggi mendadak saat retakan terbuka lebar. Kebocoran tube (tube leak) yang berulang pada lokasi yang sama (biasanya di baris pinggir dekat dinding shroud); Fluktuasi nilai DCA yang berkorelasi dengan beban unit atau suhu.

Suara berisik (rattling) dari bagian bawah heater; Hasil tes Eddy Current menunjukkan sinyal cacat (defect) volume tepat di lokasi baffle. Analisis sinyal ECT untuk membedakan antara penipisan umum (general thinning) atau gesekan lokal (fretting); Jika dilakukan penggantian tube (pull tube), lihat fisik tube bekas: akan ada cincin aus (ring scar) mengkilap di bekas posisi baffle. Standar TEMA (Tubular Exchanger Manufacturers Association) mengatur toleransi celah lubang baffle yang ketat (maks 0.4 mm); Jarak baffle di DCZ dibuat lebih pendek dibanding zona kondensasi untuk menahan tube lebih kaku. Pasang pasak (tube stakes) plastik atau logam di sela-sela tube yang longgar untuk mematikan getaran. Ini solusi paling efektif tanpa perlu retubing; Jika penipisan dinding akibat gesekan sudah >40%, tube wajib disumbat (plugged) dan dipasak (staked). +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Mendinginkan kondensat (drain) hingga 175.9 C sebelum dibuang untuk efisiensi termal.

Penggunaan baja tempa (Forged Steel) SA-266 untuk Water Box yang lebih tangguh terhadap fatigue; Desain hanger dan support pipa untuk menyerap ekspansi termal. Lakukan NDT pada las-lasan nozel (nozzle weld) setiap Major Overhaul, karena ini adalah titik tegangan tertinggi yang memicu retak; Jika pernah terjadi retak nozel, evaluasi kembali profil kecepatan aliran di area nozel.

Cek parameter Specific Steam Consumption (kg/kWh). Jika naik, berarti ada kebocoran energi; Lakukan perhitungan manual velocity; Konfirmasi lokasi kebocoran uap secara visual (gunakan termografi jika tidak terlihat mata telanjang). Pompa BFP dan HPH biasanya didesain dengan margin aliran 105-110% VWO (Valve Wide Open), namun margin ini tergerus oleh plugging tube; Mencegah overpressure sisi shell yang bisa merusak gasket. Jika kebocoran uap signifikan dan tidak bisa diisolasi (misal di hulu MOV Extraction), hitung kecepatan aliran feed water aktual; Jika hasil perhitungan menunjukkan v > 2.5 m/s, rekomendasikan penurunan beban unit (Derating). Lebih baik menurunkan MW sedikit daripada membiarkan kecepatan tinggi menggerus inlet tube HPH 5 yang tersisa, yang akan berujung pada kerusakan katastropik (retubing dini). +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Menjaga kecepatan aliran feed water 2.4 m/s dalam batas aman untuk mencegah erosi.

Indikasi aliran feed water sedikit lebih tinggi dari biasanya untuk beban MW yang sama; Seringkali terdeteksi dari penyimpangan kualitas air (karena air bocoran mengganggu keseimbangan kimia di shell side). Air Test: Beri tekanan udara pada sisi shell, gunakan air sabun pada muka tube sheet; Vacuum Test: Tarik vakum di sisi shell, pasang plastik pada tube sheet. Plastik akan cekung di tube yang bocor. Batasan kecepatan aliran (2.4 m/s) di manual. Alih-alih mematikan tube (plugging) yang akan semakin mempersempit area aliran dan menaikkan kecepatan, pertimbangkan pemasangan Sleeves sepanjang 10-12 inci pada inlet tube.

Terlihat pola kulit jeruk atau horseshoe marks pada permukaan dalam mulut tube; Kebocoran yang selalu terjadi di area inlet (dekat tube sheet), bukan di tengah heater. Lakukan inspeksi ECT dengan fokus khusus pada sinyal di area expansion transition dan 200mm pertama tube; Hitung ulang kecepatan aliran aktual dengan mempertimbangkan jumlah plug saat ini (53 + plug baru). Monitoring flow BFP Jika persentase plugging sudah >10-15% (untuk HPH 5: 53 tube mungkin sudah mendekati batas ini tergantung total tube), pertimbangkan Retubing atau Replacement Heater. Menambah plug lagi hanya akan menaikkan kecepatan di sisa tube secara eksponensial dan mempercepat kegagalan total; Batasi beban maksimum unit (MW) agar total aliran feed water tidak menghasilkan kecepatan >2.5 m/s pada sisa tube yang ada. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Menjaga kecepatan aliran feed water 2.4 m/s dalam batas aman untuk mencegah erosi.

Lonjakan kecepatan sesaat memberikan dampak kerusakan yang jauh lebih besar daripada operasi stabil; Ketidakstabilan level drum dan tekanan uap utama. Grafik Feedwater Flow di DCS membentuk gelombang sinus/gerigi (sawtooth); Suara pompa BFP mendengung naik-turun ("menggerung"). Pindahkan kontrol BFP ke Manual. Jika aliran stabil, masalah ada pada parameter kontrol (Gain/Reset). Jika tetap tidak stabil, masalah ada pada aktuator (scoop tube) atau hidrolik pompa.

Operator merasa aman karena tidak ada alarm "High Flow", padahal di dalam HPH 5 sedang terjadi pengikisan masif; Percepatan kerusakan tube yang menyebabkan kebocoran tube prematur dan sering. Seringkali tidak ada indikasi alarm sampai terjadi kebocoran tube. Indikasi hanya bisa dilihat jika Engineer melakukan perhitungan manual kecepatan vs beban. Periksa nilai High Limit pada blok fungsi kontrol Feedwater Flow di DCS. Apakah nilainya masih nilai desain asli (misal 2400 t/h) atau sudah dikurangi? Biasanya bergantung pada kewaspadaan System Owner/Engineer. Sangat Direkomendasikan untuk mengubah High Flow Alarm atau Load Limiter di DCS; Pasang stiker atau pop-up peringatan di HMI operator: "HPH 5 Plugged 53 Tubes.

Secara berkala hitung kecepatan aliran aktual di dalam tube menggunakan data total aliran (Feedwater Flow di DCS) dibagi dengan total area penampang tube yang masih aktif (total tube awal dikurangi tube yang di-plug dan tersumbat); Buka manway pada channel head (Water Box) dan lakukan inspeksi visual langsung atau menggunakan borescope untuk melihat adanya benda asing yang menutupi tube sheet atau penumpukan deposit di mulut tube. erdapat strainer pada suction BFP untuk menyaring partikel besar, namun partikel halus atau benda asing yang tertinggal di dalam pipa setelah BFP (saat maintenance) bisa langsung masuk ke HPH; Pemantauan parameter dP Feedwater Heater di DCS Terapkan prosedur FME tanpa kompromi setiap kali membuka Water Box HPH 5 saat overhaul. Pastikan tidak ada alat, sisa gasket, atau kain majun yang tertinggal; Jika jumlah tube yang di-plug bertambah, Engineering harus menghitung ulang batas beban maksimum unit; Jika sumbatan disebabkan oleh deposit oksida yang menebal lambat laun, jadwalkan pembersihan tube (high-pressure water jetting atau bullet cleaning) pada jadwal outage berikutnya. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Menjaga kecepatan aliran feed water 2.4 m/s dalam batas aman untuk mencegah erosi.

Heat Rate unit memburuk. Penurunan mendadak atau bertahap pada temperatur Feedwater Outlet HPH 5, sementara tekanan dan level uap normal; BFP harus memompa aliran total yang sedikit lebih tinggi untuk mengkompensasi kerugian efisiensi pemanasan di boiler. Saat unit shutdown dan diisolasi, buka Manway Water Box dan lakukan inspeksi visual langsung pada pelat partisi pembagi. Pelat partisi didesain dengan ketebalan ekstra sebagai corrosion allowance. Lakukan penambalan las (weld patch) pada area pelat partisi yang berlubang atau menipis parah; Jika korosi berulang, pertimbangkan untuk melapisi (cladding) permukaan pelat partisi dengan material Stainless Steel (misal SS 304/316L) yang jauh lebih tahan terhadap erosi aliran feed water. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Menjaga kecepatan aliran feed water 2.4 m/s dalam batas aman untuk mencegah erosi.

Terjadi penurunan nilai Differential Pressure (delta P) sisi feed water secara mendadak (karena aliran langsung melompat dari inlet ke outlet tanpa hambatan tube); Mungkin terdengar benturan logam dari dalam Water Box saat perubahan beban. Kombinasi delta P feed water yang rendah dengan temperatur outlet yang drop tajam adalah indikasi pasti kegagalan partisi. Pelat partisi dilas secara penuh dan kokoh pada struktur bejana; Adanya katup pengisian lambat (warming valve / bypass) untuk menaikkan tekanan heater secara bertahap. Operator wajib mematuhi prosedur line-up dan warming-up HPH 5.

Kecepatan dalam Tube: 2.4 m/s; Pressure Drop Sisi feed water: 1.17 bar Gagal menjaga kecepatan aliran feed water dalam batas aman (melebihi 2.4 m/s) Tube Inlet Ends Structural deficiency Wear Profil mulut tube yang tajam/rusak akibat aus menciptakan fenomena vena contracta, di mana aliran air terlepas dari dinding tube sesaat setelah masuk, memadat di tengah, dan kecepatannya melonjak tajam secara lokal; Kebocoran tube (tube leak) dini yang jumlahnya terus bertambah secara eksponensial. Jika dibiarkan, HPH 5 harus di-plug lebih banyak lagi, yang ironisnya akan semakin menaikkan kecepatan aliran dan memperparah erosi pada tube yang tersisa. Pola kebocoran tube sangat spesifik, yaitu selalu bocor pada jarak beberapa inci dari tube sheet sisi inlet, bukan di area U-bend atau zona kondensasi. ECT akan menunjukkan indikasi penipisan (wall thinning) yang persis terpusat di area transisi inlet; Inspeksi visual pada mulut tube akan memperlihatkan pola keausan seperti kuku kuda (horseshoe marks) atau kulit jeruk. Desain awal memastikan ujung tube dilas rata (flush) atau di-chamfer untuk memastikan aliran masuk yang mulus (smooth entry). Tindakan perbaikan paling efektif (selain retubing) adalah memasang sisipan selongsong logam tipis (inlet ferrules/sleeves) sepanjang 15-20 cm pada mulut tube-tube sisi inlet; Mengingat sudah ada 53 tube yang di-plug, Engineering harus menetapkan batas maksimal (plugging limit margin). Jika batas ini tercapai, pemakaian HPH 5 harus di-derating (dibatasi aliran maksimumnya) untuk mencegah runaway wear. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Menjaga kecepatan aliran feed water 2.4 m/s dalam batas aman untuk mencegah erosi.

Karena HPH 5 sudah memiliki 53 tube yang di-plug, setiap tambahan plugging akan semakin memperkecil area penampang aliran feed water. Terdengar suara bising/gemuruh (rumbling) frekuensi rendah dari arah shell di dekat nozel inlet uap; Adanya riwayat kebocoran tube yang terpusat pada barisan terluar (peripheral tubes) yang berhadapan langsung dengan arah aliran uap. Lakukan analisis getaran akustik pada badan HPH; Inspeksi lokasi kebocoran tube saat outage menggunakan Eddy Current Test (ECT). Jika kebocoran terjadi di zona desuperheating terluar, kecepatan uap adalah penyebab utamanya. Impingement plate (pelat pelindung) dipasang di depan nozel masuk uap untuk memecah energi kinetik uap. Inspeksi kondisi impingement plate. Jika pelat berlubang atau terlepas, segera perbaiki; Jika jumlah plugging sudah banyak akibat getaran masa lalu, terapkan Derating MW (penurunan batas beban maksimal turbin) untuk menjaga total aliran feed water tidak melampaui batas kecepatan 2.4 m/s di sisa tube yang aktif. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Menjaga kecepatan aliran feed water 2.4 m/s dalam batas aman untuk mencegah erosi.

Tube akan bergesekan dengan lubang penyangga terus-menerus; Keausan gesek (fretting wear) menyebabkan dinding tube habis dan bocor. Penanganan standar (mem-plug tube) kembali memicu siklus pengurangan area efektif, yang pada akhirnya menaikkan kecepatan rata-rata aliran feed water di atas batas aman pada tube yang tersisa. Getaran tidak terdengar jelas dari luar (cenderung silent failure); Meningkatnya tren makeup water atau parameter konduktivitas yang menunjukkan adanya tube leak kecil yang kronis. Analisis sinyal ECT saat overhaul. Indikasi kuat celah longgar adalah ditemukannya pola cacat penipisan cincin (ring wear defect) pada interval yang bertepatan persis dengan jarak antar baffle. Fabrikasi mematuhi standar toleransi celah TEMA (Tubular Exchanger Manufacturers Association). Jangan langsung mem-plug tube jika penipisan belum kritis.

Memaksakan HPH 5 beroperasi pada beban nominal setelah plugging massal ini dijamin akan merusak batas 2.4 m/s dan menghancurkan sisa tube karena erosi kecepatan internal yang ekstrem. Terdengar suara dengungan bernada tinggi yang nyaring (singing/whining) yang muncul atau menghilang pada tingkat pembebanan (aliran) tertentu. Rekam profil akustik dengan mikrofon industri; Cabut sampel tube yang rusak (tube pull) dan periksa permukaan luarnya. Ciri khas tabrakan antar tube adalah adanya titik benturan datar memanjang (flat spots). Desain jarak antar penyangga (baffle span) yang optimal untuk memastikan frekuensi natural tube tetap tinggi. Identifikasi titik beban MW di mana fenomena ini terjadi. Jadikan titik tersebut sebagai zona larangan operasi (exclusion zone); Turunkan kecepatan aliran secara sistemik dengan mengubah rute beban pompa jika memungkinkan. Jika kerusakan terlalu parah, ganti tube bundle (retubing) karena HPH tidak lagi mampu menjaga kecepatan feed water yang aman. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Menjaga kecepatan aliran feed water 2.4 m/s dalam batas aman untuk mencegah erosi. Kecepatan dalam Tube: 2.4 m/s; Pressure Drop Sisi feed water: 1.17 bar Gagal menjaga kecepatan aliran feed water dalam batas aman (melebihi 2.4 m/s) Impingement Plate, Subcooler Shroud, Baffle Plates, Subcooler U-Tubes Tube Vibration Abnormal operation Lonjakan kecepatan aliran feed water sesaat (flow surge) secara langsung melanggar batas 2.4 m/s; Aliran internal berkecepatan tinggi ini membawa energi kinetik masif yang memicu Internal Flow-Induced Vibration. Tube bergetar hebat dari dalam, menimbulkan tegangan tinggi pada las-lasan sudut di pelat tube (tube sheet), memicu retak fatigue dan erosi inlet seketika. Getaran atau suara hantaman keras (hydraulic shock/hammering) hanya terjadi saat manuver beban, saat start-up BFP, atau saat konfigurasi bypass pemanas sedang aktif; Alarm lonjakan aliran (Flow High) pada HMI DCS. Korelasikan data historian DCS antara posisi control valve feed water / kecepatan BFP dengan waktu kemunculan suara getaran atau kejadian kebocoran tube Aturan operasional pada Instruction Manual TJB membatasi manuver kecepatan aliran dan laju pemanasan Terapkan parameter Rate Limiter (pembatas laju perubahan sinyal) yang lebih ketat pada algoritma kendali BFP di DCS agar operator tidak bisa secara tidak sengaja memicu flow surge; Buat prosedur interlock: jika HPH 6 atau 7 di-bypass, batas atas pembebanan Boiler Feed Pump otomatis diturunkan untuk mencegah overspeed aliran internal pada HPH 5 yang menanggung sisa beban pemanasan. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Menjaga kecepatan aliran feed water 2.4 m/s dalam batas aman untuk mencegah erosi. Kecepatan dalam Tube: 2.4 m/s; Pressure Drop Sisi feed water: 1.17 bar Gagal menjaga kecepatan aliran feed water dalam batas aman (melebihi 2.4 m/s) Impingement Plate, Subcooler Shroud, Baffle Plates, Subcooler U-Tubes Flashing at Subcooler Poor water level control Kavitasi menggerus dinding luar tube di area subcooler hingga tipis dan akhirnya pecah (rupture); Pecahnya tube menyebabkan BFP menaikkan putaran untuk mengejar defisit air ke boiler; Suhu drain melonjak (DCA tinggi), memicu water hammer di pipa drain. Fluktuasi level air (hunting) yang selalu diikuti oleh lonjakan nilai DCA (Drain Cooler Approach); Indikasi aliran Feedwater di DCS tiba-tiba lebih tinggi daripada Steam Flow, diikuti kenaikan arus motor BFP; Suara gemuruh kavitasi seperti kerikil yang diputar dari bagian bawah HPH. Bandingkan grafik bukaan Drain Control Valve dengan grafik Level; Saat dicurigai ada kebocoran akibat flashing, hitung seketika kecepatan aliran aktual: Total Flow dibagi area efektif sisa tube. Jika >2.4 m/s, statusnya kritis. Sistem PID pada Drain Control Valve diatur untuk menjaga Normal Water Level (NWL) tetap merendam inlet subcooler. Alarm Level Low. Naikkan setpoint Level Normal di DCS sekitar 50-100 mm untuk memberikan bantalan (margin) segel air yang lebih tebal terhadap undershoot saat transien beban; Jika tube yang rusak akibat flashing harus di-plug, Engineering wajib mengevaluasi ulang total luas penampang yang tersisa. Jika penambahan plug ini membuat kecepatan air pada MCR (Beban Penuh) melampaui 2.4 m/s, unit harus di-Derating (dibatasi beban maksimal turbin/BFP-nya) untuk menyelamatkan umur sisa HPH 5. +Feedwater High Pressure Feedwater Heater 5 (HPH 5) 3FW-H050 Horizontal closed tubular type Menjaga kecepatan aliran feed water 2.4 m/s dalam batas aman untuk mencegah erosi. Kecepatan dalam Tube: 2.4 m/s; Pressure Drop Sisi feed water: 1.17 bar Gagal menjaga kecepatan aliran feed water dalam batas aman (melebihi 2.4 m/s) Impingement Plate, Subcooler Shroud, Baffle Plates, Subcooler U-Tubes Flashing at Subcooler Shroud or end plate leakage Sama seperti penyebab pertama, tube yang terpotong akan membocorkan feed water secara masif; BFP merespons dengan runout (menaikkan debit maksimal). Karena HPH 5 beroperasi dengan 53 plug, lonjakan aliran BFP ini menaikkan kecepatan air di dalam sisa tube hingga melampaui batas desain 2.4 m/s. Akibatnya, terjadi kerusakan ganda: Tube pinggir rusak karena flashing eksternal, tube tengah rusak karena erosi kecepatan internal. Hidden Level Issue: Sangat mengecoh karena Level Air di DCS tampak normal dan stabil, namun nilai DCA sangat tinggi secara persisten; Sejarah kebocoran tube (tube leak) yang selalu berulang di lokasi spesifik, yakni pada baris terluar dekat pelat shroud atau end plate. Lakukan Eddy Current Test. Jika peta kerusakan menunjukkan kumpulan penipisan dinding tube secara spesifik hanya di area perimeter subcooler, ini mengkonfirmasi adanya kebocoran shroud; Saat HPH dibuka, lakukan tes tekanan udara dari sisi shell dan periksa area shroud dengan air sabun untuk menemukan titik retak. Desain shroud dilas penuh dan dihitung untuk menahan perbedaan tekanan parsial di dalam shell. Perbaiki retakan shroud dengan pengelasan presisi dan pastikan tegangan sisa dihilangkan untuk mencegah retak berulang; Mengingat HPH 5 sudah sangat rentan terhadap pengurangan luas penampang (kecepatan >2.4 m/s), tube yang berada tepat di depan area retakan shroud sebaiknya diganti dengan Dummy Tubes (batang pejal padat) alih-alih di-plug. Dummy tubes akan menahan semburan flashing di masa depan tanpa mengurangi area aliran feed water di dalam tube bundle. +Feedwater +Feedwater High Pressure Feedwater Heater 6 (HPH 6) 3FW-H060 Horizontal closed tubular type Meningkatkan temperatur feedwater dari HP 5 dengan input 211.5 C hingga mencapai output 244.2 C menuju HP 7 Laju Alir feed water: 1,998,594 kg/h; Suhu Masuk: 211.5 C; Suhu Keluar: 244.2 C; Terminal Temp.

Hal ini dapat memicu kenaikan level air hingga mencapai HHWL (High-High Water Level), yang mengisolasi uap ekstraksi dan melakukan bypass pada sisi feed water untuk melindungi turbin. Level kondensat di shell HP 6 berfluktuasi (hunting) di sekitar setpoint; Katup Normal Drain bergerak membuka/menutup secara mendadak tanpa perubahan beban turbin.

Jika level disetel terlalu tinggi, air akan merendam tube-tube kondensasi secara permanen; Penenggelaman area efektif pemanasan secara konstan ini menyebabkan perpindahan panas laten uap tidak terjadi secara optimal. Sistem stabil tanpa alarm, valve tenang, namun performa termal (TTD) memburuk secara konstan dan suhu target 285.9 C tidak pernah tercapai meskipun beban turbin 100%. Periksa batas Setpoint operasional di HMI DCS. Verifikasi elevasi titik nol (0%) transmitter secara fisik terhadap General Arrangement Drawing HPH 7 (Pastikan 0% masih mematuhi batas aman perendaman tube). Lembar data instrumen (Instrument Datasheet) yang memuat parameter kompensasi densitas. Kunci (Lock) parameter pengaturan limit Setpoint Level di DCS. Berikan akses administratif berlapis agar operator tidak bisa secara sewenang-wenang mengubah target level di luar rentang operasi termal yang diizinkan oleh standar Performance Engineering. +Feedwater High Pressure Feedwater Heater 7 (HPH 7) 3FW-H070 Horizontal closed tubular type Memanaskan feed water (air umpan) dari suhu 244.2 C ke suhu akhir 285.9 C sebelum economizer/boiler Laju Alir feed water: 1,998,594 kg/h; Suhu Masuk: 244.2 C; Suhu Keluar: 285.9 C; Terminal Temp.

Ini menciptakan ledakan uap bertekanan tinggi yang sangat berbahaya bagi personel (scalding hazard) dan merusak insulasi di sekitarnya; HPH 7 wajib segera diisolasi (Cut-out / Bypass). Akibatnya, feed water tidak lagi melewati tube pemanas HPH 7. Terlihat kabut uap tebal (steam cloud) di area Heater Bay lantai atas; Terdengar suara desisan atau gemuruh keras dari area Water Box HPH 7; Adanya genangan air panas di lantai sekitar HPH 7. Segera evakuasi area. Observasi dari jarak aman atau menggunakan kamera CCTV untuk memastikan sumber semburan uap berasal dari celah Manway atau flange HPH 7. Penggunaan Pressure Seal Gasket khusus tegangan tinggi (biasanya terbuat dari mild steel atau silver-plated ring) yang dirancang agar semakin rapat saat tekanan internal naik. Selalu ganti gasket dengan tipe dan spesifikasi yang sama persis setelah Manway dibuka. Jangan pernah menggunakan ulang gasket pressure seal bekas; Periksa secara teliti permukaan dudukan gasket (gasket seating surface) dari goresan radial (meski hanya sehelai rambut). Goresan kecil pada tekanan >200 bar akan menjadi jalur bocor yang membesar akibat erosi (wire-drawing effect). +Feedwater High Pressure Feedwater Heater 7 (HPH 7) 3FW-H070 Horizontal closed tubular type Memanaskan feed water (air umpan) dari suhu 244.2 C ke suhu akhir 285.9 C sebelum economizer/boiler Laju Alir feed water: 1,998,594 kg/h; Suhu Masuk: 244.2 C; Suhu Keluar: 285.9 C; Terminal Temp.

Jika dibiarkan, aliran air berkecepatan tinggi ini akan mengikis logam baut dan flange (wire-drawing), hingga akhirnya paking jebol (blowout); Sama seperti penyebab Leakage, heater harus di-bypass. Pembuangan panas HPH 7 hilang total, target pemanasan 285.9 C gagal dicapai, dan Economizer berisiko mengalami thermal shock karena menerima air yang jauh lebih dingin dari desain. Munculnya kerak putih (deposit mineral) atau jejak aliran karat di bawah baut Manway; Desisan uap halus yang terlihat saat inspeksi rutin operator lokal. Lakukan pengecekan torsi (Torque Check) menggunakan kunci torsi hidrolik pada kondisi dingin (depressurized) untuk memverifikasi apakah baut kehilangan tegangannya. Prosedur pengencangan menyilang (criss-cross tightening pattern) dengan hydraulic tensioner untuk memastikan beban tarik merata di semua baut. Lakukan pengencangan ulang panas (hot retorquing) sesuai anjuran pabrikan setelah unit kembali beroperasi dan mencapai suhu/tekanan kerjanya paska-overhaul; Berikan garis marka cat melintang pada mur dan stud bolt setelah proses pengencangan selesai. Hal ini memudahkan inspeksi visual: jika marka tidak segaris, berarti mur telah berputar/longgar. +Feedwater High Pressure Feedwater Heater 7 (HPH 7) 3FW-H070 Horizontal closed tubular type Memanaskan feed water (air umpan) dari suhu 244.2 C ke suhu akhir 285.9 C sebelum economizer/boiler Laju Alir feed water: 1,998,594 kg/h; Suhu Masuk: 244.2 C; Suhu Keluar: 285.9 C; Terminal Temp.

External leakage-Process medium Mechanical failure-general Kegagalan katastropik (Catastrophic Failure). Struktur penahan tekanan robek, menyebabkan ledakan air bertekanan tinggi yang bisa merobohkan struktur di sekitarnya; Ini adalah Forced Outage (Trip Unit) darurat. Jika kebocoran terlampau besar, level Drum Boiler akan anjlok tajam (Low-Low Drum Level Trip) karena BFP tidak mampu mengkompensasi volume air yang bocor keluar dari retakan HPH 7. Suara dentuman logam yang keras atau getaran hebat sebelum munculnya semburan air/uap raksasa; Alarm deviasi aliran (Feedwater Flow Deviation) dan penurunan level Drum Boiler secara mendadak. Setelah unit aman dan diisolasi, lakukan pengujian Non-Destructive Testing (NDT) seperti Magnetic Particle Testing (MT) atau Ultrasonic Testing (UT) tingkat lanjut (seperti Phased Array) untuk memetakan kedalaman dan panjang retakan pada dinding Water Box. Konstruksi Water Box umumnya menggunakan bentuk Hemisperikal (Hemispherical Head) yang mampu mendistribusikan tegangan tekanan paling merata dibanding bentuk lain; Hydrostatic Test di atas tekanan operasi (misal 1.5x) saat fabrikasi. Pastikan operator selalu menggunakan katup warming-up (pengisian lambat) untuk menyamakan tekanan dan suhu HPH 7 sebelum membuka katup Inlet/Outlet Main Valve feed water secara penuh; Masukkan area las-lasan nozel Feedwater Inlet HPH 7 ke dalam program NDT wajib setiap inspeksi Major Overhaul (C-Inspection), karena ini adalah titik tegangan tertinggi (high-stress concentration point). +Feedwater High Pressure Feedwater Heater 7 (HPH 7) 3FW-H070 Horizontal closed tubular type Memanaskan feed water (air umpan) dari suhu 244.2 C ke suhu akhir 285.9 C sebelum economizer/boiler Laju Alir feed water: 1,998,594 kg/h; Suhu Masuk: 244.2 C; Suhu Keluar: 285.9 C; Terminal Temp.

Semburan uap ini juga dapat merusak insulasi termal di sekitarnya dan memicu korosi eksternal; Uap yang bocor keluar berarti massa uap pemanas yang masuk ke dalam bundle tube HPH 7 berkurang Terdengar suara mendesis yang tajam atau gemuruh dari area Heater Bay lantai atas. Terlihat kepulan kabut uap yang keluar dari balik insulasi HPH 7 atau jalur pipa ekstraksinya; Indikasi suhu Feedwater Outlet di DCS perlahan turun atau tidak mampu mencapai 285.9 C meskipun beban turbin 100%. Tekanan shell HPH 7 terbaca lebih rendah dari tekanan desain pada beban yang sesuai. Lakukan lokalisasi sumber suara uap bocor (gunakan kamera termal jika lokasi tertutup insulasi atau berada di ketinggian); Bandingkan Terminal Temperature Difference (TTD) dan tekanan shell saat ini dengan kurva performa komisioning. Jika suhu feed water turun tetapi TTD tetap normal/bagus, itu menandakan tekanan/suhu uap pemanasnya yang bermasalah (hilang akibat bocor). Penggunaan Spiral Wound Gasket dengan pengisi grafit (graphite filler) pada flange pipa uap. Badan shell dilas penuh dan telah melewati Hydrostatic Test dan pengujian NDT (Radiografi/Ultrasonik) saat fabrikasi. Jika kebocoran terjadi pada flange pipa uap ekstraksi atau valve packing dan membahayakan efisiensi (namun heater belum perlu di-trip), gunakan jasa Online Leak Sealing (injeksi compound / Furmanite) untuk menutup kebocoran saat unit sedang beroperasi penuh; Jika kebocoran berasal dari stem packing katup, jadwalkan pengencangan gland follower oleh mekanik dengan APD lengkap; Jika lasan pipa uap/drain sering retak dan bocor, ini mengindikasikan adanya tegangan perpipaan (pipe stress) akibat getaran atau ekspansi termal yang terhambat. Evaluasi kembali hanger dan support pipa di sekitar HPH 7. +Feedwater High Pressure Feedwater Heater 7 (HPH 7) 3FW-H070 Horizontal closed tubular type Memanaskan feed water (air umpan) dari suhu 244.2 C ke suhu akhir 285.9 C sebelum economizer/boiler Laju Alir feed water: 1,998,594 kg/h; Suhu Masuk: 244.2 C; Suhu Keluar: 285.9 C; Terminal Temp. Difference (TTD): -2 C; Luas permukaan Pemanas: 1,793 m2 (setelah pemasangan 44 prevention plugs) Gagal memanaskan feed water ke suhu 285.9 C sebelum masuk ke economizer/boiler U-Tubes (Tube Bundle) Internal leakage Breakage Semburan feed water dingin (~250 C) dalam volume masif langsung membanjiri shell HPH 7; Proses pemanasan terhenti seketika. HPH 7 gagal mencapai 285.9 C. Lebih buruk lagi, level air di shell akan naik dengan sangat cepat memicu Trip HHWL (High-High Water Level) Terdengar suara dentuman keras dari dalam badan heater; Munculnya rentetan alarm "Heater Level High", diikuti "Heater Level High-High" dan "Extraction MOV Auto-Close" dalam hitungan detik; Penurunan tajam seketika pada grafik temperatur Feedwater Outlet. Setelah HPH 7 terisolasi, lakukan Hydrotest pada sisi tube (tube side). Air akan memancar deras keluar dari saluran drain sisi shell yang dibiarkan terbuka. Sistem Interlock Proteksi Turbin: Sensor level redundan akan men-trip-kan HPH (menutup katup ekstraksi dan membuka katup bypass feed water) secara otomatis saat level sangat tinggi. Saat melakukan plugging (penyumbatan) pada tube yang patah, wajib memasukkan batang penstabil (dummy rod / stabilizer) ke dalam tube tersebut sebelum di-plug. Hal ini mencegah sisa tube yang patah mencambuk (whipping) dan menghancurkan tube-tube sehat di sekitarnya saat terkena turbulensi aliran uap. +Feedwater High Pressure Feedwater Heater 7 (HPH 7) 3FW-H070 Horizontal closed tubular type Memanaskan feed water (air umpan) dari suhu 244.2 C ke suhu akhir 285.9 C sebelum economizer/boiler Laju Alir feed water: 1,998,594 kg/h; Suhu Masuk: 244.2 C; Suhu Keluar: 285.9 C; Terminal Temp. Difference (TTD): -2 C; Luas permukaan Pemanas: 1,793 m2 (setelah pemasangan 44 prevention plugs) Gagal memanaskan feed water ke suhu 285.9 C sebelum masuk ke economizer/boiler U-Tubes Internal leakage Burst feed water menyemprot keluar seperti pisau air bertekanan tinggi (jet impingement), langsung memotong dinding tube-tube sehat yang berada di dekatnya; Air bocoran ini menyerap panas uap ekstraksi. Bukaan Drain Control Valve akan merangkak naik ke 100% untuk membuang kelebihan air ini. Grafik bukaan Drain Control Valve di DCS menunjukkan tren naik yang tidak normal (misal dari biasanya 45% bergeser ke 80% pada beban turbin konstan); TTD (Terminal Temperature Difference) melebar secara persisten. Saat unit shutdown, lakukan pengujian Eddy Current Test (ECT) secara menyeluruh. Petakan lokasi tube yang pecah. Katup pengaman sisi shell (Shell Safety Relief Valve) untuk mencegah tekanan shell melebihi batas desain jika terjadi kebocoran internal masif. Jangan hanya mem-plug tube yang pecah. Evaluasi "zona ledakan" (blast zone) dan lakukan plugging preventif pada radius 1 hingga 2 baris tube di sekeliling tube yang pecah, karena dinding mereka kemungkinan besar sudah terkikis tipis oleh semburan (impingement damage). +Feedwater High Pressure Feedwater Heater 7 (HPH 7) 3FW-H070 Horizontal closed tubular type Memanaskan feed water (air umpan) dari suhu 244.2 C ke suhu akhir 285.9 C sebelum economizer/boiler Laju Alir feed water: 1,998,594 kg/h; Suhu Masuk: 244.2 C; Suhu Keluar: 285.9 C; Terminal Temp. Difference (TTD): -2 C; Luas permukaan Pemanas: 1,793 m2 (setelah pemasangan 44 prevention plugs) Gagal memanaskan feed water ke suhu 285.9 C sebelum masuk ke economizer/boiler Tube-to-Tubesheet Weld Joints, U-Tubes (pinhole) Internal leakage Leakage Laju kebocoran sangat kecil sehingga tidak memicu alarm level; Meskipun kecil, air dingin yang terus-menerus masuk ke shell mencuri panas laten dari uap ekstraksi. Target pemanasan 285.9 C akan "meleset" tipis (misal hanya mencapai 284 C). Dalam jangka panjang, kerugian termal kumulatif ini cukup signifikan memboroskan biaya bahan bakar. Selain itu, pinhole akan perlahan membesar menjadi burst akibat erosi internal bocoran (wire-drawing). Sangat sulit dideteksi secara real-time. Indikasi utama adalah analisis tren efisiensi Heat Rate dan TTD yang memburuk sangat lambat selama berbulan-bulan. Saat HPH 7 diisolasi untuk pemeliharaan, tarik vakum pada sisi shell dan semprotkan busa sabun atau pasang lembaran plastik tipis pada muka tube sheet. Plastik akan tersedot ke dalam tube yang memiliki kebocoran mikro. Pelaporan rutin (harian/mingguan) oleh Performance Engineer memantau deviasi DCA dan TTD HPH. Jadikan uji hidrostatik (Hydrostatic Test) sisi tube pada tekanan nominal kerja sebagai kewajiban setiap kali melakukan Major Overhaul, untuk mengungkap kebocoran mikro sebelum unit kembali sinkron ke jaringan. +Feedwater High Pressure Feedwater Heater 7 (HPH 7) 3FW-H070 Horizontal closed tubular type Memanaskan feed water (air umpan) dari suhu 244.2 C ke suhu akhir 285.9 C sebelum economizer/boiler Laju Alir feed water: 1,998,594 kg/h; Suhu Masuk: 244.2 C; Suhu Keluar: 285.9 C; Terminal Temp.

HPH 7 akan kehilangan kemampuannya mencapai 285.9 C secara permanen (derated capability). Terjadinya tube leak berulang-ulang yang memaksa HPH 7 sering diisolasi; Tingkat plugging (tube yang disumbat) mendekati atau melampaui batas margin desain awal pabrikan (biasanya margin desain hanya menoleransi 10-15% tube di-plug). Lakukan pencabutan sampel tube yang rusak (tube pull-out) dan kirim ke laboratorium metalurgi untuk mengkonfirmasi apakah struktur mikro material (biasanya Carbon Steel tegangan tinggi) telah mengalami degradasi batas butir (SCC) atau kelelahan termal. Kurva pemanasan operasional (batasan laju kenaikan suhu maksimal, misal < 200 C/jam) saat start-up unit. Jika total plugging sudah melampaui batas batas aman termal dan HPH 7 secara konsisten gagal mencapai suhu desain, satu-satunya solusi permanen adalah merencanakan Retubing (penggantian seluruh bundel tube) atau penggantian bejana HPH 7 secara utuh; Edukasi operator untuk secara ketat mematuhi laju pemanasan (ramp rate) saat manuver unit. Kecerobohan membuka katup ekstraksi terlalu cepat akan langsung memendekkan umur sisa tube bundle HPH 7 akibat thermal shock. +Feedwater High Pressure Feedwater Heater 7 (HPH 7) 3FW-H070 Horizontal closed tubular type Memanaskan feed water (air umpan) dari suhu 244.2 C ke suhu akhir 285.9 C sebelum economizer/boiler Laju Alir feed water: 1,998,594 kg/h; Suhu Masuk: 244.2 C; Suhu Keluar: 285.9 C; Terminal Temp.

Uap ekstraksi tidak bisa mentransfer panas latennya secara efektif ke dinding tube; Suhu feed water (Feedwater Outlet Temperature) perlahan-lahan drop dan tidak akan mampu mencapai 285.9 C meskipun beban unit 100%. Kegagalan ini memaksa Boiler untuk membakar lebih banyak batubara guna memanaskan air yang masuk ke Economizer (Heat Rate Penalty). Nilai TTD (Terminal Temperature Difference) melebar secara perlahan/bertahap dari bulan ke bulan; Terjadi kenaikan pelan pada Differential Pressure (delta P) sisi feed water HPH 7 jika fouling cukup tebal di dalam tube. Lakukan perhitungan Heat Exchanger Performance dengan membandingkan parameter aktual saat operasi beban penuh (MCR) terhadap kurva desain komisioning; Cek temperatur pada pipa continuous vent ke kondensor; jika pipanya dingin, berarti jalur venting tersumbat (terjadi gas blanketing). Kontrol kimia feed water (AVT/CWT) yang ketat untuk mencegah penumpukan besi; Sistem Continuous Venting dengan orifice diatur untuk membuang sebagian kecil uap beserta NCG secara terus-menerus. Jadwalkan Chemical Cleaning atau pembersihan mekanis (bullet cleaning) pada sisi tube HPH 7 saat Major Overhaul jika degradasi TTD sudah melewati batas keekonomian; Pastikan orifice atau valve pada jalur operating vent dibersihkan dan dipastikan terbuka (tidak mampet) saat unit beroperasi. +Feedwater High Pressure Feedwater Heater 7 (HPH 7) 3FW-H070 Horizontal closed tubular type Memanaskan feed water (air umpan) dari suhu 244.2 C ke suhu akhir 285.9 C sebelum economizer/boiler Laju Alir feed water: 1,998,594 kg/h; Suhu Masuk: 244.2 C; Suhu Keluar: 285.9 C; Terminal Temp.

Temperatur Feedwater Outlet drop secara tiba-tiba (step change), bukan perlahan; Indikator posisi katup bypass di DCS menunjukkan persentase $> 0\%$, atau Steam Flow ekstraksi menurun meskipun beban (MW) tetap. Pindahkan mode control valve yang dicurigai ke Manual di DCS. Jika parameter tidak berubah, lakukan pengecekan visual pada stem katup secara fisik di lapangan (apakah valve positioner atau handwheel bergeser dari posisi tertutup/buka penuh). Indikasi posisi balik (Position Feedback) katup dan Alarm di DCS (misal: "Heater Bypass Valve Not Fully Closed"). Lakukan kalibrasi ulang (stroke test) pada aktuator Feedwater Bypass Valve. Pastikan saat perintah 0%, katup benar-benar tight shut-off (tertutup rapat, tidak ada passing); Jika bypass valve sering bermasalah dan bocor, pertimbangkan untuk merantai dan menggembok (chain and padlock) katup isolasi manual pada jalur bypass selama operasi normal. +Feedwater High Pressure Feedwater Heater 7 (HPH 7) 3FW-H070 Horizontal closed tubular type Memanaskan feed water (air umpan) dari suhu 244.2 C ke suhu akhir 285.9 C sebelum economizer/boiler Laju Alir feed water: 1,998,594 kg/h; Suhu Masuk: 244.2 C; Suhu Keluar: 285.9 C; Terminal Temp.

Parameter deviation Out of adjustment Level air kondensat di dalam shell naik secara konstan melebihi Normal Water Level (NWL) yang direkomendasikan pabrikan; Tube yang terendam air kondensat kehilangan kemampuannya menyerap panas laten dari uap. Luas penampang perpindahan panas menyusut drastis. Akibatnya, feed water tidak dapat menyerap cukup kalori dan suhunya akan stagnan (misal di 278 C - 280 C), gagal menembus target desain 285.9 C. Kehilangan suhu sekian derajat di HPH 7 sangat merugikan Heat Rate unit. Parameter Level DCS terlihat stabil pada setpoint-nya tanpa ada alarm (karena sistem berjalan sesuai setpoint yang salah tersebut); Suhu keluar Feedwater tertahan di bawah target padahal aliran ekstraksi uap dan beban turbin maksimal; TTD melebur/buruk, tetapi DCA (Drain Cooler Approach) mungkin terlihat sangat bagus/kecil karena kondensat yang menumpuk mengalami sub-cooling berlebihan. Bandingkan nilai Setpoint Level saat ini di DCS dengan nilai di Instruction Manual atau dokumen Heat Balance Diagram (HBD) TJB; Verifikasi elevasi titik tap instrumen Level Transmitter secara fisik menggunakan referensi as-built drawing (pastikan titik ukur nol 0% tidak berada terlalu tinggi yang merendam zona kondensasi). Batas operasional (Operating Windows) yang diberikan oleh Performance Engineer. Segera turunkan Setpoint Level secara bertahap ke nilai Normal Water Level desain. Pantau pemulihan kenaikan suhu feed water yang akan terjadi secara bersamaan seiring terpaparnya kembali tube ke ruang uap; Kunci (Password Protect) pengaturan limit setpoint level pada Engineering Workstation DCS agar operator lapangan tidak bisa secara sepihak memanipulasi setpoint di luar jendela operasi termal yang aman. +Feedwater High Pressure Feedwater Heater 7 (HPH 7) 3FW-H070 Horizontal closed tubular type Memanaskan feed water (air umpan) dari suhu 244.2 C ke suhu akhir 285.9 C sebelum economizer/boiler Laju Alir feed water: 1,998,594 kg/h; Suhu Masuk: 244.2 C; Suhu Keluar: 285.9 C; Terminal Temp.

Permukaan tube tersebut kehilangan fungsinya untuk menyerap panas dari uap ekstraksi secara permanen; Aliran total feed water dipaksa masuk ke tube yang tersisa. Kecepatan aliran melonjak ekstrem, memicu Inlet End Erosion pada tube yang masih sehat, yang akan berujung pada kebocoran beruntun; Dengan hilangnya persentase besar area perpindahan panas efektif, HPH 7 secara fisik "cacat" dan tidak lagi memiliki kapasitas untuk mengangkat suhu feed water ke 285.9 C. Temperatur keluar tidak pernah mencapai 285.9 C meskipun katup uap ekstraksi terbuka 100% dan tekanan shell normal; Kenaikan drastis pada selisih tekanan feed water antara masuk (inlet) dan keluar (outlet) HPH 7; Arus motor Boiler Feed Pump meningkat signifikan untuk melawan hambatan (delta P) dari HPH 7 tersebut. Periksa peta tube plugging map dari riwayat overhaul sebelumnya. Hitung persentase tube yang sudah mati; Saat unit offline, buka Manway Water Box dan lakukan inspeksi langsung pada muka Tube Sheet untuk melihat apakah ada material asing atau kerak tebal yang memblokir mulut tube. Strainer pada sisi suction Boiler Feed Pump (namun jarang ada strainer khusus persis sebelum HPH 7 karena tekanan yang sangat tinggi); Pemantauan parameter batas delta P feed water di DCS; Batas toleransi Plugging Margin dari manufaktur (biasanya sekitar 10%). Terapkan protokol Foreign Material Exclusion (FME) yang sangat ketat saat melakukan pekerjaan di area perpipaan hulu atau saat membuka bejana penukar panas; Jika sumbatan berupa kerak atau deposit keras, jadwalkan High-Pressure Water Jetting pada tube saat jadwal pemeliharaan besar (C-Inspection); Jika kegagalan mencapai 285.9 C murni disebabkan oleh persentase manual plugging yang sudah melebihi batas desain (misal >15% tube di-plug), Engineering harus membuat kajian keekonomian untuk segera melakukan Retubing (penggantian bundel tube) atau pengadaan HPH 7 baru. Operasi lanjutan dengan HPH 7 yang "lumpuh" hanya akan membuang miliaran rupiah dari inefisiensi konsumsi batubara setiap bulannya. +Feedwater High Pressure Feedwater Heater 7 (HPH 7) 3FW-H070 Horizontal closed tubular type Memanaskan feed water (air umpan) dari suhu 244.2 C ke suhu akhir 285.9 C sebelum economizer/boiler Laju Alir feed water: 1,998,594 kg/h; Suhu Masuk: 244.2 C; Suhu Keluar: 285.9 C; Terminal Temp.

Structural deficiency Corrosion Jika pelat partisi Water Box berlubang, feed water bertekanan tinggi (sisi inlet) akan langsung menyemprot tembus ke sisi outlet tanpa mengalir melewati tube pemanas (tube bundle); Jika pelat Desuperheating Zone berlubang, uap ekstraksi yang superpanas akan langsung bocor ke Condensing Zone (ruang utama) tanpa mendingin terlebih dahulu di zona desuperheating; Efisiensi perpindahan panas hancur. Suhu Feedwater Outlet akan drop jauh di bawah 285.9 C Penurunan suhu feed water HPH 7 secara bertahap (jika korosi membesar pelan-pelan). TTD (Terminal Temperature Difference) terlihat sangat buruk/melebar; Jika pelat partisi air berlubang, hambatan HPH 7 berkurang, sehingga delta P feed water antara inlet dan outlet akan turun secara tidak wajar. Jika Suhu drop namun delta P feed water juga drop, ini adalah indikasi kuat adanya Internal Bypass di Water Box; Jika Suhu drop namun $\Delta P$ feed water juga drop, ini adalah indikasi kuat adanya Internal Bypass di Water Box. Pelat partisi didesain dengan ketebalan ekstra (corrosion allowance) atau menggunakan pelapisan Stainless Steel pada area berkecepatan tinggi. Lakukan penambalan las atau penggantian sebagian pelat partisi yang mengalami korosi parah; Jika korosi FAC sangat agresif di HPH 7, terapkan pelapisan paduan tahan korosi (weld overlay cladding menggunakan Inconel atau Stainless Steel) pada permukaan pelat partisi. +Feedwater High Pressure Feedwater Heater 7 (HPH 7) 3FW-H070 Horizontal closed tubular type Memanaskan feed water (air umpan) dari suhu 244.2 C ke suhu akhir 285.9 C sebelum economizer/boiler Laju Alir feed water: 1,998,594 kg/h; Suhu Masuk: 244.2 C; Suhu Keluar: 285.9 C; Terminal Temp.

Jika penyangga baffle yang patah, tube-tube kehilangan penahannya dan melengkung/saling berbenturan; Sama seperti mekanisme korosi namun terjadi secara mendadak. Suhu feed water akan anjlok seketika (gagal total mencapai 285.9 C) karena mayoritas air tidak masuk ke tube bundle. Jika ini memicu kebocoran tube masif, HPH 7 harus di-trip (bypass penuh). Suhu keluar Feedwater jatuh secara tiba-tiba (step change); Terdengar suara dentuman keras atau benturan logam dari dalam bejana saat transien operasi terjadi. Cek laju pemanasan (ramp rate) saat unit start-up sesaat sebelum kejadian. Jika laju pemanasan jauh melebihi batas (misal >200 C/jam), kemungkinan besar terjadi patah akibat thermal shock; Pengujian Dye Penetrant (PT) atau Magnetic Particle (MT) pada lasan-lasan penyangga struktur saat jadwal overhaul. SOP (Standard Operating Procedure) yang membatasi laju kenaikan beban dan suhu untuk menghindari thermal fatigue. Wajibkan operator untuk selalu melakukan warming-up (pengisian lambat) melalui katup bypass berukuran kecil sebelum mengalirkan feed water atau uap ekstraksi secara penuh ke dalam HPH 7; Jika impingement plate uap sering terlepas/patah, konsultasikan dengan manufaktur untuk modifikasi desain penyangga yang lebih kokoh (misalnya desain sangkar/ cage). +Feedwater High Pressure Feedwater Heater 7 (HPH 7) 3FW-H070 Horizontal closed tubular type Memanaskan feed water (air umpan) dari suhu 244.2 C ke suhu akhir 285.9 C sebelum economizer/boiler Laju Alir feed water: 1,998,594 kg/h; Suhu Masuk: 244.2 C; Suhu Keluar: 285.9 C; Terminal Temp.

Tube akan mengalami erosi dan vibrasi hebat hingga akhirnya bocor parah; Persilangan air akibat keausan gasket membuat suhu campuran feedwater tidak pernah bisa mencapai 285.9 C secara konstan. Efisiensi suhu menurun sangat lambat namun konstan, seringkali diawali setelah unit baru saja selesai overhaul (indikasi pemasangan gasket partisi kurang presisi); Kebocoran tube (tube leak) yang persis berlokasi di baris-baris pertama di depan nozzle inlet uap ekstraksi. Saat membuka Water Box, periksa apakah ada jalur kikisan air (water tracking/cutting) pada permukaan dudukan logam pelat partisi atau pada gasketnya; Masukkan kamera borescope melalui saluran drain atau inspeksi sisi uap untuk melihat ketebalan sisa impingement plate. Pelat impingement didesain tebal (biasanya baja tuang atau pelat SS tebal) untuk menahan energi kinetik seumur hidup heater. Pastikan mekanik benar-benar membersihkan dan mengukur kerataan (flatness) permukaan pelat partisi sebelum memasang gasket baru. Ketidakrataan sedikit saja akan memicu keausan semburan (washout); Jika pelat pelindung uap sudah aus atau tidak bisa diganti di lapangan, tube-tube baris terdepan yang berhadapan dengan nozzle uap sebaiknya diganti dengan solid dummy rods (batang pejal) untuk bertindak sebagai pelindung/tameng bagi sisa tube aktif di belakangnya. +Feedwater High Pressure Feedwater Heater 7 (HPH 7) 3FW-H070 Horizontal closed tubular type Memanaskan feed water (air umpan) dari suhu 244.2 C ke suhu akhir 285.9 C sebelum economizer/boiler Laju Alir feed water: 1,998,594 kg/h; Suhu Masuk: 244.2 C; Suhu Keluar: 285.9 C; Terminal Temp.

Operator harus mengisolasi HPH 7, mem-plug tube yang rusak, lalu mengoperasikannya kembali dengan kapasitas panas yang sudah berkurang; Suhu feedwater outlet akan meleset dari target 285.9 C, memaksa boiler membakar ekstra batubara. Terdengar suara gemuruh (rumbling) frekuensi rendah dari badan shell di dekat nozel ekstraksi uap saat beban turbin tinggi; Kebocoran tube yang selalu terpusat pada barisan terluar di area Desuperheating Zone. Analisis lokasi kerusakan menggunakan Eddy Current Test (ECT) saat outage. Jika kerusakan dominan di area tumbukan uap masuk, kecepatan uap adalah penyebabnya. Pemasangan pelat pelindung (Impingement Plate) di depan nozel uap masuk untuk memecah dan mendistribusikan kecepatan uap sebelum menyentuh tube aktif. Pastikan impingement plate masih utuh. Uap HPH 7 sangat agresif dan bisa mengikis pelat ini seiring waktu; Jika kecepatan uap terbukti merusak baris pertama tube, ganti tube-tube tersebut dengan solid stainless steel dummy rods (batang pejal). Batang ini akan menyerap energi getaran uap tanpa risiko membocorkan feed water ke dalam shell, sehingga sisa tube di belakangnya aman dan area pemanasan terjaga. +Feedwater High Pressure Feedwater Heater 7 (HPH 7) 3FW-H070 Horizontal closed tubular type Memanaskan feed water (air umpan) dari suhu 244.2 C ke suhu akhir 285.9 C sebelum economizer/boiler Laju Alir feed water: 1,998,594 kg/h; Suhu Masuk: 244.2 C; Suhu Keluar: 285.9 C; Terminal Temp.

Logam tube tergerus dan menipis tepat di titik pertemuan dengan pelat baffle; Gesekan memicu kebocoran (tube leak). Sama seperti siklus destruktif lainnya, tube harus di-plug. Akumulasi plugging akibat masalah baffle ini secara perlahan namun pasti mereduksi area perpindahan panas, membuat kurva suhu HPH 7 tertahan (misal maksimal 280 C) dan tidak bisa lagi menyentuh 285.9 C. Cenderung menjadi silent failure (tidak ada suara bising mencolok); Kenaikan lambat pada parameter konsumsi air penambah (Make-up Water) unit, indikasi adanya kebocoran internal yang awalnya kecil. ECT akan memperlihatkan cacat berbentuk cincin (ring wear defect) pada jarak yang presisi secara berulang (sesuai dengan jarak antar baffle di dalam shell); Cabut satu tube yang dicurigai (tube pull) dan periksa secara visual adanya alur gesekan di dinding luar tube. Standar toleransi pabrikasi TEMA (Tubular Exchanger Manufacturers Association) untuk batas maksimal celah baffle. Perbaikan paling efektif adalah menyisipkan pasak peredam getaran (anti-vibration tube stakes) di sela-sela bundel tube yang longgar. Pasak ini mengunci tube agar tidak bergerak, menghentikan keausan tanpa perlu mematikan (mem-plug) tube tersebut. Area pemanasan terselamatkan. +Feedwater High Pressure Feedwater Heater 7 (HPH 7) 3FW-H070 Horizontal closed tubular type Memanaskan feed water (air umpan) dari suhu 244.2 C ke suhu akhir 285.9 C sebelum economizer/boiler Laju Alir feed water: 1,998,594 kg/h; Suhu Masuk: 244.2 C; Suhu Keluar: 285.9 C; Terminal Temp.

Tube Vibration Fluidelastic whirring or vortex shedding Tube-tube melengkung hebat dan saling bertabrakan satu sama lain di bagian tengah antara dua penyangga (mid-span clashing). Kerusakan fisik yang ditimbulkan sangat masif dan cepat; Menimbulkan puluhan kebocoran tube secara bersamaan. HPH 7 harus di-Trip Darurat (Bypass Penuh). Suhu feedwater yang masuk ke Economizer akan anjlok drastis (hanya membawa suhu keluaran HPH 6), menyebabkan termal shock pada boiler dan kegagalan total pencapaian suhu 285.9 C dalam jangka panjang karena HPH 7 harus outage untuk perbaikan skala besar. Terdengar suara nyanyian bernada tinggi (singing / whining) atau dengungan keras dari dalam heater pada saat beban MW turbin berada di titik spesifik tertentu; Ledakan jumlah tube leak dalam waktu yang sangat singkat. Rekam profil akustik heater dan analisis spektrum frekuensinya; Ditemukan titik tumbukan datar (flat spots) memanjang pada permukaan tube di area mid-span (tengah-tengah bentang). Perhitungan Vibration Analysis saat desain awal memastikan jarak penyangga (baffle span) dibuat cukup pendek agar frekuensi natural tube jauh lebih tinggi dari frekuensi vortex shedding. Identifikasi laju aliran uap (atau beban MW) yang memicu resonansi ini. Atur logika di DCS untuk menetapkan beban tersebut sebagai zona larangan operasi (exclusion zone); turbin tidak boleh ditahan lama pada beban tersebut; Jika HPH 7 harus di-retubing, ubah konfigurasi baffle (misal menggunakan Double Segmental atau No-Tubes-in-Window) untuk mengubah kecepatan aliran uap silang dan mematikan resonansi. +Feedwater High Pressure Feedwater Heater 7 (HPH 7) 3FW-H070 Horizontal closed tubular type Memanaskan feed water (air umpan) dari suhu 244.2 C ke suhu akhir 285.9 C sebelum economizer/boiler Laju Alir feed water: 1,998,594 kg/h; Suhu Masuk: 244.2 C; Suhu Keluar: 285.9 C; Terminal Temp. Difference (TTD): -2 C; Luas permukaan Pemanas: 1,793 m2 (setelah pemasangan 44 prevention plugs) Gagal memanaskan feed water ke suhu 285.9 C sebelum masuk ke economizer/boiler Extraction Steam MOV Tube Vibration Abnormal operation Menimbulkan gelombang kejut pneumatik/hidrolik (shockwave). Tube mengalami guncangan sesaat layaknya dicambuk; Retakan las memicu internal leakage. Heater diisolasi untuk plugging. Sama seperti sebelumnya, akumulasi plugging mengurangi kapasitas perpindahan panas, mengunci performa HPH 7 di bawah target 285.9 C selama sisa siklus operasinya. Terasa getaran fisik sesaat pada struktur perpipaan dan badan HPH 7 hanya pada saat laju perubahan beban tinggi; Alarm parameter limit berkedip sesaat saat ramp-up/down. Lakukan investigasi riwayat historian DCS. Bandingkan waktu munculnya indikasi kebocoran/getaran dengan grafik laju perubahan beban (Ramp Rate) atau kecepatan bukaan katup MOV ekstraksi. Katup Warming-up (katup bypass kecil) yang didesain untuk menyamakan tekanan shell secara perlahan sebelum katup MOV utama dibuka penuh. Terapkan pembatasan laju pergerakan (Rate Limiter) secara hardcode di logika DCS untuk aktuator katup MOV Ekstraksi, sehingga katup tidak bisa terbuka mendadak meskipun operator memberikan perintah buka 100% secara instan; Berikan instruksi tegas bahwa katup utama uap ekstraksi HPH 7 tidak boleh dibuka sebelum tekanan shell mencapai parameter minimum warming-up yang ditetapkan di manual TJB. +Feedwater High Pressure Feedwater Heater 7 (HPH 7) 3FW-H070 Horizontal closed tubular type Memanaskan feed water (air umpan) dari suhu 244.2 C ke suhu akhir 285.9 C sebelum economizer/boiler Laju Alir feed water: 1,998,594 kg/h; Suhu Masuk: 244.2 C; Suhu Keluar: 285.9 C; Terminal Temp.

Indikasi level air di DCS berayun liar (hunting) atau sering menyentuh alarm Low Level; Nilai DCA (Drain Cooler Approach) melonjak drastis (sangat panas, > 15 C) bersamaan dengan jatuhnya level air; Suara gemeratak keras seperti batu kerikil yang dihancurkan (gravel-like rattling) dari bagian bawah shell HPH 7. Tarik data historis DCS. Jika lonjakan DCA selalu sinkron dengan momen penurunan level air kondensat, maka steam ingestion (masuknya uap memicu flashing) terkonfirmasi murni karena kendali level yang buruk. Desain snorkel atau pelat penahan pusaran (anti-vortex baffle) di inlet subcooler untuk mencegah uap tersedot ke bawah; Logika PID kontroler level kondensat. Naikkan Normal Water Level (NWL) setpoint di DCS sekitar +50 mm hingga +100 mm dari standar awal. Ini memberikan "bantalan" segel air yang lebih tebal untuk mengkompensasi undershoot saat beban turbin berubah cepat; Lakukan fine-tuning pada kontroler Drain Control Valve agar pergerakannya lebih halus (kurangi nilai Gain/Proportional), mencegah katup membuka terlalu lebar secara mendadak. +Feedwater High Pressure Feedwater Heater 7 (HPH 7) 3FW-H070 Horizontal closed tubular type Memanaskan feed water (air umpan) dari suhu 244.2 C ke suhu akhir 285.9 C sebelum economizer/boiler Laju Alir feed water: 1,998,594 kg/h; Suhu Masuk: 244.2 C; Suhu Keluar: 285.9 C; Terminal Temp.

Semburan ini langsung menghantam tube-tube yang posisinya berdekatan dengan dinding shroud yang retak (direct impingement); Kebocoran tube yang diakibatkan sangat terlokalisir tapi mematikan. feed water membanjiri shell, efisiensi HPH 7 anjlok. Berbeda dengan penyebab pertama, pada kasus ini Level Air di DCS terlihat sangat normal dan stabil, namun nilai DCA tetap sangat tinggi secara persisten (karena terjadi internal bypass kondensat panas ke jalur subcooler); Jika ditarik data tube plugging map, kerusakan tube selalu terkonsentrasi di area pinggir luar (periphery) dari zona pendingin drain, dekat dengan pelat shroud. Saat overhaul, tarik vakum atau berikan tekanan udara dari sisi shell luar sambil melakukan inspeksi visual (dengan air sabun) di sepanjang jalur lasan shroud subcooler; Masukkan kamera melalui lubang drain untuk melihat kondisi fisik pelat penutup subcooler. Desain shroud dibuat dengan toleransi pemuaian bebas (sliding support atau ekspansi termal terpisah) agar tidak mudah retak akibat tegangan panas. Perbaiki retakan pada shroud menggunakan prosedur pengelasan yang tepat, diikuti dengan Post-Weld Heat Treatment (PWHT) lokal jika memungkinkan, untuk menghilangkan tegangan sisa (residual stress); Jika retakan shroud sulit dijangkau untuk dilas dengan sempurna, pasang batang baja pejal (solid dummy rods) pada lubang tube sheet yang berhadapan langsung dengan retakan tersebut. +Feedwater High Pressure Feedwater Heater 7 (HPH 7) 3FW-H070 Horizontal closed tubular type Menahan tekanan fluida pada sisi tube 232 bar(g) dan sisi shell 80.8 bar(g) Tekanan Desain Sisi Tube: 232.0 bar(g); Tekanan Desain Sisi Shell: 80.8 bar(g); Suhu Desain Sisi Shell: 297 C (Inlet Steam: 443 C) Gagal menahan tekanan fluida 232 bar(g) pada sisi tube dan 80.8 bar(g) pada sisi shell BFP Speed Controller (DCS Logic), Boiler Feed Pump VSD/Scoop Tube.

Penurunan tekanan seketika di retakan tersebut menciptakan aliran semburan dua fase (flashing jet) berkecepatan sonik. Level kontrol terlihat normal dan stabil, tetapi kebocoran tube (tube leak) selalu berulang di lokasi spesifik (baris terluar zona subcooler). Lakukan tes tekanan udara dari sisi shell saat overhaul dan semprotkan air sabun di sepanjang lasan pelat shroud zona subcooler untuk mencari titik retakan penahan tekanan kompartemen. Desain shroud baja dilas penuh Lakukan Weld Repair pada shroud yang retak; Pasang Solid Dummy Rods (batang pejal) di lubang tube sheet yang langsung berhadapan dengan retakan shroud.

Abnormal instrument reading Control failure BFP memompa air secara fluktuatif (surge). Puncak-puncak lonjakan aliran (flow spikes) ini menembus batas debit maksimal, menyebabkan kecepatan air di dalam tube melonjak jauh di atas 2.4 m/s sesaat. Guncangan kecepatan ini mengikis lapisan oksida pelindung di mulut tube secara agresif. Bukaan Scoop Tube / arus motor BFP berayun (hunting), aliran FW di DCS membentuk grafik gigi gergaji (sawtooth). Pindahkan kontrol BFP ke Manual untuk melihat apakah fluktuasi aliran berhenti. Rate limiter dan PID tuning pada DCS.

Abnormal instrument reading Corrosion Flowmeter membaca aliran "Rendah Palsu". Sistem kontrol BFP secara otomatis merespons dengan menambah putaran pompa untuk mencapai target aliran. Akibatnya, debit air aktual yang masuk ke HPH 7 jauh lebih besar dari yang terbaca di layar, mendorong kecepatan aktual melampaui 2.4 m/s tanpa disadari operator (blind overspeed). Level drum boiler naik drastis padahal indikator aliran FW di DCS terlihat normal/rendah. Arus pompa BFP tinggi. Bandingkan Feedwater Flow dengan Main Steam Flow. Lakukan blowdown jalur impuls flowmeter. Voting 2oo3 untuk sensor aliran.

Abnormal instrument reading Faulty signal/indication/alarm Sama seperti penyumbatan, jika sensor mengalami drift negatif (membaca lebih kecil 10% dari aktual), operator akan merasa aman beroperasi pada MCR, padahal aliran aktual sudah menghasilkan kecepatan >2.5 m/s di dalam HPH 7, memicu penipisan tube massal. Mismatch antara Total Feedwater Flow aktual dengan konsumsi uap teoritis pada MW yang sama. Kalibrasi injeksi elektronik pada Flow Transmitter. Alarm deviasi antar transmitter redundan.

Abnormal instrument reading Looseness Getaran konstan di area pompa BFP atau pemipaan HPH 7 menyebabkan baut terminal di Junction Box (JB) atau Marshalling Cabinet menjadi longgar. Hal ini menciptakan kontak intermiten (intermittent contact); Jika sinyal aliran tiba-tiba drop (seolah-olah aliran hilang), kontroler BFP yang berada dalam mode Auto akan merespons agresif dengan mengirim perintah "Naikkan Kecepatan" (Speed Up) ke Scoop Tube atau VSD untuk mengembalikan aliran ke setpoint. Tren aliran feed water (Feedwater Flow) terlihat "kotor" atau berbulu (hashy/noisy), dengan garis-garis vertikal tajam (spikes) yang tidak wajar; Scoop Tube BFP atau Control Valve terlihat bergerak maju-mundur (hunting) mengikuti sinyal yang kacau tersebut; Sering muncul alarm sesaat (chattering alarm) seperti "Flow Deviation High". Secara hati-hati goyangkan kabel instrumen di terminal Flow Transmitter atau JB terdekat saat memantau nilai di multimeter/DCS. Jika nilai melompat saat kabel disentuh, kelonggaran terkonfirmasi; Periksa kekencangan baut terminal menggunakan obeng yang sesuai (pastikan prosedur keselamatan listrik dipatuhi). Pengaturan Damping Time (misal: 2-5 detik) pada konfigurasi transmitter atau DCS untuk meredam fluktuasi sinyal sesaat agar kontroler tidak bereaksi berlebihan; Batasan laju perubahan sinyal input di logika DCS. Ganti terminal blok tipe baut biasa dengan tipe Spring-Loaded (Cage Clamp) di area dengan vibrasi tinggi. Terminal pegas secara otomatis menyesuaikan cengkeraman saat ada getaran, mencegah kelonggaran; Masukkan pengecekan kekencangan terminal (retightening) instrumen kritis HPH 7 ke dalam jadwal pemeliharaan rutin tahunan atau saat outage. +Feedwater High Pressure Feedwater Heater 7 (HPH 7) 3FW-H070 Horizontal closed tubular type Menjaga kecepatan aliran feed water 2.4 m/s Kecepatan dalam Tube: 2.4 m/s; Pressure Drop Sisi feed water: 1.23 bar Gagal menjaga kecepatan aliran feed water pada 2.4 m/s Flow Transmitter Electronic Module, Instrument Signal Cables, Junction Box Terminals. Abnormal instrument reading No signal/indication/alarm Jika logika kontrol tidak memiliki proteksi "Bad Quality", kontroler akan membaca "Aliran = 0". Kontroler akan memerintahkan BFP untuk Runout (Kecepatan Maksimum) demi menyelamatkan boiler yang dikira "kekeringan". Nilai aliran menunjukkan angka minimum skala (misal -25%) atau berubah warna menjadi Ungu/Kuning (menandakan status komunikasi putus / Bad PV); Muncul alarm prioritas tinggi: "Sensor Break", "Input Open Circuit", atau "Transmitter Fault"; Arus motor BFP (Amper) tetap tinggi atau naik, meskipun indikasi flow nol (kontradiksi data). Ukur tegangan terminal di lapangan (harus ada 24V DC); Ukur resistansi kabel (loop resistance) dari ruang kontrol ke lapangan untuk mencari titik putus. Logika DCS biasanya diprogram untuk menahan output terakhir (Hold Last Value) atau memindahkan kontroler ke Manual Mode secara otomatis jika kualitas sinyal input menjadi "Bad"; Penggunaan 3 sensor aliran (Voting 2oo3) sehingga jika satu sensor mati (No Signal), sistem otomatis mengabaikannya dan menggunakan rata-rata dua sensor lain. Pastikan seluruh rute kabel instrumen Feedwater Flow dari transmitter hingga masuk ke gedung utama dilindungi oleh pipa baja (rigid conduit) atau tray tertutup untuk mencegah kerusakan fisik (terpotong/terjepit); Saat commissioning atau loop check, verifikasi bahwa respons sistem saat kabel dicabut (simulated wire break) adalah "Hold Last Value" atau "Trip to Manual", dan BUKAN memerintahkan pompa naik ke 100%.

Abnormal instrument reading Out of adjustment Jika HPH 7 sudah memiliki banyak tube yang di-plug, area penampangnya (A) mengecil. Jika High Flow Limit di DCS tidak diturunkan (masih menggunakan setelan pabrik 0 plug), operator bisa menaikkan beban hingga batas lama. Pada titik tersebut, karena lubang lebih sedikit, kecepatan air (v) sudah sangat jauh melampaui 2.4 m/s. Tidak ada alarm, namun tube leak akibat erosi inlet sering berulang saat unit beroperasi di beban penuh. Audit nilai High Limit Flow di program kontrol DCS dan bandingkan dengan jumlah plug aktual HPH 7. Dokumentasi Plugging Map. Wajib Update Logic Batas Aliran.

Suara desisan tajam atau gemuruh dari balik insulasi Water Box. Terlihat kabut uap tebal; Feedwater Flow di sisi suction BFP lebih tinggi daripada Main Steam Flow, padahal level drum stabil atau cenderung turun. Lakukan pengamatan dari jarak aman (gunakan binokular atau CCTV) untuk memastikan sumber kebocoran adalah dari celah tutup Manway; Tutup Inlet/Outlet Valve HPH 7. Jika kebocoran berhenti, konfirmasi gasket jebol. Penutup Manway menggunakan desain pressure seal di mana tekanan internal justru memperkuat kerapatan gasket. Jangan biarkan HPH 7 beroperasi dengan kebocoran Manway. Turbulensi di Water Box akan menghancurkan profil aliran laminar. Segera isolasi HPH; Pastikan penggantian gasket menggunakan spesifikasi OEM (biasanya cincin logam lunak atau grafoil kepadatan tinggi) dan periksa permukaan dudukan (seating surface) dari goresan radial. +Feedwater High Pressure Feedwater Heater 7 (HPH 7) 3FW-H070 Horizontal closed tubular type Menjaga kecepatan aliran feed water 2.4 m/s Kecepatan dalam Tube: 2.4 m/s; Pressure Drop Sisi feed water: 1.23 bar Gagal menjaga kecepatan aliran feed water pada 2.4 m/s Water Box Manway Pressure Seal Gasket, Manway Stud Bolts, Water Box Shell Body, Feedwater Nozzle Welds.

Setelah unit mati/diisolasi, lakukan pemeriksaan Magnetic Particle (MT) atau Ultrasonic (UT) pada area lasan nozel dan radius knuckle Water Box. Jalur pemanasan awal untuk mencegah thermal shock saat start-up; Penggunaan baja tempa (Forged Steel) kualitas tinggi (SA-266 / SA-508) untuk Water Box. Patuhi batasan laju perubahan suhu (<= 100-200 C). Thermal shock adalah penyebab utama retaknya komponen tebal seperti Water Box HPH 7; Lakukan Remaining Life Assessment (RLA) pada lasan nozel setiap 5-8 tahun, karena HPH 7 mengalami siklus tegangan terberat di pembangkit. +Feedwater High Pressure Feedwater Heater 7 (HPH 7) 3FW-H070 Horizontal closed tubular type Menjaga kecepatan aliran feed water 2.4 m/s Kecepatan dalam Tube: 2.4 m/s; Pressure Drop Sisi feed water: 1.23 bar Gagal menjaga kecepatan aliran feed water pada 2.4 m/s Extraction Steam Inlet Flange Gaskets, Shell Body Welds. External leakage-Utility medium Leakage Kehilangan uap menyebabkan efisiensi HPH 7 turun. Untuk mempertahankan Load (MW) yang sama, sistem kontrol Governor Turbin akan membuka katup uap utama lebih lebar. Hal ini secara langsung memerintahkan BFP menaikkan Feedwater Flow (Total Debit Q naik). Kenaikan debit ini menaikkan kecepatan rata-rata di dalam tube mendekati atau melampaui 2.4 m/s, terutama jika HPH 7 sudah mengalami sejarah plugging. Desisan uap di HPH 7, MW turun pelan, BFP flow merangkak naik. Cek spesifik konsumsi uap (SSC) dan inspeksi visual area shell. Margin kapasitas desain.

Percikan kecil statis dapat memicu ledakan hebat atau kebakaran jet fire yang sulit dipadamkan; Jika bocor adalah CO2/N2 di ruang tertutup, oksigen akan terdesak keluar, menyebabkan risiko asphyxia bagi operator; Tekanan suplai ke generator tidak stabil, menyebabkan gangguan pada sistem Auto Make-up; Pemborosan biaya operasional akibat kehilangan inventaris gas yang mahal Alarm Detektor Gas Area berbunyi; Terdengar suara desis keras frekuensi tinggi dari area rak botol karena tekanan manifold tinggi, sekitar 150 bar); Tekanan tube turun sangat cepat padahal pemakaian generator normal; Terlihat bunga es pada titik bocor akibat efek pendinginan ekspansi; Semprotkan air sabun ada semua sambungan konektor, pigtail, dan valve. Gelembung besar menandakan lokasi bocor; Gunakan detektor gas genggam untuk melacak sumber konsentrasi tertinggi; Tutup semua valve tube dan valve outlet manifold. Lihat pressure gauge manifold; jika jarum turun, berarti ada kebocoran di manifold itu sendiri; Penggunaan ulir kiri pada konektor H2 untuk mencegah salah sambung dengan tube gas lain (O2/N2); Lokasi rak gas biasanya di area terbuka beratap atau memiliki exhaust fan di titik tertinggi; Sensor api UV/IR terpasang di atas area manifold; valve satu arah pada tiap pigtail untuk mencegah gas balik menyembur jika satu pigtail putus Terapkan SOP ketat: "Satu Botol Baru = Satu Gasket Baru". Dilarang keras memakai ulang washer; Lakukan inspeksi visual dan tes kebocoran pigtail setiap kali ganti botol. Ganti pigtail secara preventif setiap 3-5 tahun; Operator wajib melakukan tes air sabun setiap kali selesai mengganti botol dan membuka valve, sebelum meninggalkan area; Pastikan manifold dan rak botol terhubung ke grounding bumi yang baik untuk membuang listrik statis; +Turbine (TUR) Turbine Steam Turbine 3MT-ST010 3MT-ST020 3MT-ST030A Menghidupkan motor DC pompa darurat (Lube/Seal). Starting torque andal saat sinyal start otomatis. Motor DC gagal memberikan starting torque untuk memutar pompa darurat saat menerima sinyal start otomatis, mengakibatkan hilangnya suplai oli pelumas/seal ke bantalan turbin pada saat kritis DC Motor Brush Gear & Commutator System (Termasuk Carbon Brushes, Brush Holders, Springs, Commutator Bars, dan Magnetic Contactor); Motor fails to start on demand Penumpukan carbon dust di dalam holder membuat carbon brush macet dan tidak terdorong oleh pegas untuk menempel ke komutator. Akibatnya, terjadi Open Circuit; Karena motor jarang beroperasi, terbentuk lapisan oksida isolator pada permukaan tembaga komutator yang menghalangi aliran arus start; Pegas penekan sikat arang melemah atau patah, sehingga kontak listrik menjadi buruk atau terputus; Kumparan solenoid pada kontaktor DC (Starter) putus atau terbakar, sehingga kontak utama tidak menutup meski ada perintah start; Starting resistor putus akibat korosi atau panas berlebih dari pengetesan sebelumnya; Tanpa oli pelumas saat turbin berputar lambat, lapisan film oli hilang. Terjadi gesekan logam-ke-logam yang melelehkan Babbitt metal bearing; permukaan jurnal poros turbin tergores parah, mengharuskan pembubutan ulang atau pengafkiran poros; Jika ini adalah pompa Emergency Seal Oil, kegagalan start menyebabkan gas hidrogen bocor dan memicu kebakaran; Perbaikan bantalan dan poros membutuhkan waktu henti unit berbulan-bulan Alarm "Lube Oil Pressure Low-Low" atau "Seal Oil Pressure Low-Low" muncul, namun status pompa DC tetap "Stop/Off"; Indikator Ampere meter DC di panel lokal menunjukkan angka 0 A saat kondisi darurat; Tidak terdengar suara dengungan khas motor DC beroperasi di area tanki oli Lihat penunjuk arus. Jika 0 Ampere padahal perintah start ada, berarti sirkuit terbuka; Tekan tombol "Emergency Start" lokal secara fisik. Jika masih tidak jalan, pukul ringan bodi motor/housing sikat, kadang getaran bisa menjatuhkan sikat arang yang macet - emergency fix; Ukur tegangan masuk di terminal motor. Jika ada tegangan tapi tidak berputar, masalah ada di internal motor (brush/winding) Prosedur OPM mewajibkan tes rutin mingguan: Mematikan pompa AC sebentar untuk memicu pompa DC start otomatis; Logika kontrol memberikan alarm "DC Pump Fail to Start" jika kontaktor tidak merespons sinyal; Alarm jika suplai baterai DC ke panel motor terputus atau drop; Lakukan inspeksi bulanan: Keluarkan sikat arang, bersihkan debu karbon dari holder dengan contact cleaner, dan pastikan sikat bisa bergerak bebas naik-turun; Ganti carbon brush jika panjangnya sisa < 40-50% atau sesuai tanda batas pabrikan; Disiplin melakukan tes operasional mingguan minimal 15-30 menit. Ini penting untuk mengikis lapisan oksida pada komutator dan memanaskan lilitan agar kering; Saat Major Overhaul, lakukan pembubutan dan undercutting pada mica komutator untuk memastikan permukaan kontak yang sempurna; +Turbine (TUR) Turbine Steam Turbine 3MT-ST010 3MT-ST020 3MT-ST030A Mengamankan lilitan motor (isolasi dielektrik). Resistansi isolasi > 1 M Ohm. Sistem isolasi dielektrik pada lilitan motor gagal memisahkan konduktor bertegangan dari bodi motor (ground), ditandai dengan penurunan nilai resistansi isolasi di bawah batas aman operasional (biasanya < 1 M Ohm); Motor Winding Insulation & Internal Components (Termasuk Armature Coils, Field Coils, Commutator Risers, dan Brush Rigging Insulation); Low insulation resistance Akumulasi debu karbon hasil gesekan sikat arang yang bercampur dengan uap oli, membentuk tracking pada permukaan isolator dan commutator risers; Space Heater mati atau putus, menyebabkan lilitan motor yang dingin menyerap kelembaban dari udara sekitar saat motor standby; Kebocoran seal poros pompa oli di sebelahnya menyebabkan oli masuk membasahi lilitan motor. Oli kotor mengandung partikel logam dan asam yang merusak varnish isolasi; Isolasi menjadi getas dan retak-retak karena usia tua dan panas operasional, memudahkan masuknya kotoran; Saat motor diperintah start otomatis/manual, arus besar akan bocor ke ground sehingga terjadi short circuit yang menyebabkan sekering DC putus atau breaker trip seketika; Motor mati total dan tidak bisa digunakan saat darurat (AC Blackout), membahayakan bantalan turbin; Jika dipaksa beroperasi dengan IR rendah, loncatan api listrik dapat terjadi di dalam motor, berpotensi memicu kebakaran, terutama jika ada oli; Kebocoran arus kecil yang konstan (parasitic load) dapat mempercepat pengosongan baterai stasiun; Alarm "DC System Ground Fault (+/-)" muncul pada panel distribusi DC utama karena motor terhubung ke bus DC; Saat pemeliharaan rutin, hasil pengukuran Insulation Resistance menunjukkan angka sangat rendah; Breaker motor trip segera setelah tombol start ditekan; Buka kabel suplai daya motor dari terminal. Ukur IR motor murni menggunakan Megger 500V DC. Jika hasil < 1 M Ohm, konfirmasi isolasi motor rusak; Buka tutup inspeksi sikat arang. Periksa apakah interior motor hitam pekat tertutup debu karbon atau basah oleh oli; Untuk motor besar, cek Polarization Index. Jika rasionya mendekati 1.0, berarti lilitan basah/kotor Space Heaters yang menyala saat motor mati untuk menjaga temperatur lilitan > temperatur lingkungan; Jadwal rutin pengukuran Megger; Desain penutup motor (biasanya IP23 atau IP44) untuk meminimalkan masuknya tetesan air/oli Bongkar motor, semprot lilitan dengan electro-cleaner solvent dan angin kering untuk membuang debu karbon dan lemak oli. Ini solusi paling umum; Jika basah karena lembab, lakukan pengeringan (baking) di oven atau gunakan lampu pemanas hingga nilai IR naik stabil di atas 2-5 M Ohm; Setelah bersih dan kering, semprot ulang dengan Red Insulating Varnish (Glyptal) untuk menutup pori-pori isolasi yang retak; Pastikan Space Heater berfungsi.

Gagal memanaskan feedwater dari suhu terendah 40.4 C hingga 58.6 C menggunakan heating steam dengan tekanan paling rendah 0.213 bara Shell Tube Vibration High steam velocity on shell side Jika kecepatan aliran uap shell melampaui batas critical velocity akibat peningkatan debit uap secara drastis, atau akibat kerusakan internal, energi kinetik dari aliran uap berkecepatan tinggi diserap oleh tube bundle membuat tube bergetar. Getaran ini menyebabkan tube mengalami clashing hingga penyok, atau bergesekan terus-menerus dengan lubang Support Plate yang mengikis dinding tube. Terdengar suara humming atau gemerincing logam (rattling) dari dalam heater saat beban tinggi; Jika kebocoran terjadi, level air heater naik (High Level Alarm) dan bukaan drain valve membesar. Analisis frekuensi suara di sekitar shell saat operasi untuk mendeteksi resonansi; Saat shutdown, periksa fisik tube bundle. Tanda pasti vibrasi adalah adanya Shiny Spots pada permukaan tube di area support plate atau antar tube. Pemasangan Impingement Plate di depan nozzle inlet dan penggunaan Tube Support Plates dengan span length untuk memaksimalkan frekuensi alami tube; Inspeksi visual rutin saat overhaul. Jika vibrasi terus terjadi, pasang Anti-Vibration Bars atau Tube Stakes di sela-sela tube untuk menambah kekakuan dan meredam getaran; Ganti tube yang mengalami penipisan dinding >40% akibat fretting wear dan perbaiki Impingement Plate jika ditemukan lepas. +Condensate Water Low Pressure Feedwater Heater 1 (LPH 1) Horizontal closed tubular type 3CO-H010 Memanaskan feedwater dari suhu terendah 40.4 C hingga 58.6 C menggunakan heating steam dengan tekanan paling rendah 0.213 bara Kecepatan feedwater 2.2 m/s dirancang untuk tidak menimbulkan resonansi atau getaran yang merusak pipa pemanas internal. Gagal memanaskan feedwater dari suhu terendah 40.4 C hingga 58.6 C menggunakan heating steam dengan tekanan paling rendah 0.213 bara Shell Tube Vibration Fluidelastic whirring Jika kecepatan aliran uap melampaui critical velocity, gaya eksitasi fluida meningkat sehingga tube menyerap energi dari aliran uap sehingga terjadi getaran yang melampaui batas elastisitas material. Getaran ini mengakibatkan tube-to-tube clashing dan tube-to-support plate hammering. Tumbukan fisik yang intens dan berulang ini menyebabkan penipisan dinding pipa akibat fretting wear dan flattening pada permukaan tube. Terdengar suara dengungan frekuensi rendah yang sangat keras (roaring/humming) dari dalam shell heater, yang volumenya meningkat seiring kenaikan beban; Jika kegagalan sudah lanjut, muncul alarm High Drain Level akibat tube pecah. Lakukan pengukuran getaran pada dinding shell untuk melihat dominasi frekuensi alami tube. Saat outage, cari tanda fisik khas whirling yaitu: pola abrasi berbentuk elips pada titik kontak antar tube di antara dua support plate Perhitungan untuk menentukan Maximum Unsupported Span guna memastikan kekakuan tube; Monitoring suara dan vibrasi rutin oleh operator lapangan. Masukkan Tube Stakes atau Anti-Vibration Bars dari material stainless steel atau plastik khusus ke sela-sela barisan tube untuk mengunci pergerakan tube dan meningkatkan frekuensi alami tanpa perlu retubing; Jika memungkinkan, kurangi kecepatan inlet dengan memodifikasi impingement plate atau menambah area aliran. +Condensate Water Low Pressure Feedwater Heater 1 (LPH 1) Horizontal closed tubular type 3CO-H010 Memanaskan feedwater dari suhu terendah 40.4 C hingga 58.6 C menggunakan heating steam dengan tekanan paling rendah 0.213 bara Kecepatan feedwater 2.2 m/s dirancang untuk tidak menimbulkan resonansi atau getaran yang merusak pipa pemanas internal. Gagal memanaskan feedwater dari suhu terendah 40.4 C hingga 58.6 C menggunakan heating steam dengan tekanan paling rendah 0.213 bara Shell Tube Vibration Vortex shedding Resonansi akustik akibat vortex shedding menghasilkan osilasi tegak lurus terhadap arah aliran uap sehingga terbentuk standing wave di dalam rongga shell yang menghasilkan kebisingan. Getaran ini memicu cyclic stress pada dinding tube yang menyebabkan fatigue. Meskipun amplitudonya terbatas, getaran konstan ini perlahan akan mematahkan tube di area u-bend atau sambungan tube sheet. Terdengar suara dengungan yang sangat keras dari heater. Nada suara biasanya konstan pada beban tertentu; Suara/getaran mungkin muncul hanya pada rentang beban tertentu (misal: 60-70% load) dan hilang jika beban dinaikkan atau diturunkan. Ubah beban unit dengan menaikkan/menurunkan aliran uap). Jika suara/getaran hilang saat beban berubah, kemungkinan besar itu adalah Vortex Shedding karena frekuensi shedding berubah seiring kecepatan aliran; Analisis spektrum getaran untuk melihat puncak frekuensi tunggal. Penggunaan Support Plate dengan jarak yang diatur untuk menghasilkan frekuensi alami tube yang jauh lebih tinggi daripada frekuensi shedding maksimum; Pemasangan pelat pemecah (Detuning Baffles) di sisi shell Pasang Tube Stakes di antara tube untuk mengubah frekuensi alami tube agar tidak lagi beresonansi dengan aliran; Jika masalah utamanya adalah kebisingan akustik, pasang pelat baffle tambahan di dalam shell untuk memecah ruang resonansi suara. +Condensate Water Low Pressure Feedwater Heater 1 (LPH 1) Horizontal closed tubular type 3CO-H010 Memanaskan feedwater dari suhu terendah 40.4 C hingga 58.6 C menggunakan heating steam dengan tekanan paling rendah 0.213 bara Kecepatan feedwater 2.2 m/s dirancang untuk tidak menimbulkan resonansi atau getaran yang merusak pipa pemanas internal. Gagal memanaskan feedwater dari suhu terendah 40.4 C hingga 58.6 C menggunakan heating steam dengan tekanan paling rendah 0.213 bara Tube Support Plate Tube Vibration Baffle gap is too far Jarak antara Tube Support Plate yang terlalu jauh membuat tube mudah bergetar dan batang tube mengalami defleksi berlebih saat menerima beban aliran uap. Hal ini menyebabkan fenomena Tube-to-Tube Clashing, menciptakan pola kerusakan berupa penyok atau collision flats. Selain itu, getaran memicu fretting wear hingga akhirnya tube bocor atau patah akibat fatigue. Terdengar suara rattling atau benturan logam internal dari dalam shell, terutama saat beban berubah; Jika gesekan sudah menembus dinding tube, akan muncul gejala umum kebocoran (High Level Alarm, Drain Valve membuka lebar). Saat unit shutdown, buka shell manhole atau gunakan borescope. Periksa bagian tengah tube di antara dua baffle. Indikasi utamanya adalah adanya mid-span collision marks yang terlihat mengkilap; Goyangkan tube secara manual dengan tangan/alat; jika baffle gap terlalu jauh, tube akan terasa sangat longgar/lentur. Perhitungan Maximum Unsupported Span berdasarkan standar TEMA (Tubular Exchanger Manufacturers Association) saat fase engineering; Inspeksi rutin saat overhaul Karena posisi baffle permanen, solusi perbaikannya adalah memasang Tube Stakes tepat di tengah span untuk meningkatkan kekakuan dan frekuensi alami tube secara drastis. +Condensate Water Low Pressure Feedwater Heater 1 (LPH 1) Horizontal closed tubular type 3CO-H010 Memanaskan feedwater dari suhu terendah 40.4 C hingga 58.6 C menggunakan heating steam dengan tekanan paling rendah 0.213 bara Kecepatan feedwater 2.2 m/s dirancang untuk tidak menimbulkan resonansi atau getaran yang merusak pipa pemanas internal. Gagal memanaskan feedwater dari suhu terendah 40.4 C hingga 58.6 C menggunakan heating steam dengan tekanan paling rendah 0.213 bara Impingement Plate Tube Vibration High Inlet Velocity Jika kecepatan uap melebihi desain, pelat akan bergetar dan merambat ke struktur penyangga atau menciptakan turbulensi aliran di belakang pelat yang menghantam tube-tube di baris pertama. Hal ini menyebabkan tube ikut bergetar, mengalami gesekan, dan berisiko bocor akibat fatigue atau erosi tumbukan. Terdengar suara berisik yang terlokalisir di area Steam Inlet Nozzle; Terasa getaran pada dinding shell di dekat nozzle inlet. Saat unit shutdown, buka manhole shell atau gunakan borescope. Periksa apakah pelat masih terpasang kencang, apakah ada retak pada las-lasan, dan periksa kondisi tube baris pertama di belakang pelat Penggunaan material Stainless Steel yang tahan erosi dan korosi, serta dimensi pelat yang lebih besar dari diameter nozzle inlet untuk memastikan cakupan perlindungan; Inspeksi rutin saat Major Overhaul. Jika pelat ditemukan bergetar namun masih utuh, lakukan pengelasan ulang dengan penambahan stiffener atau lakukan reinforcement weld untuk meningkatkan kekakuan pelat; Jika vibrasi terus berulang, pertimbangkan desain ulang pelat dengan profil aerodinamis atau ganti dengan material yang lebih tebal. +Condensate Water Low Pressure Feedwater Heater 1 (LPH 1) Horizontal closed tubular type 3CO-H010 Memanaskan feedwater dari suhu terendah 40.4 C hingga 58.6 C menggunakan heating steam dengan tekanan paling rendah 0.213 bara Kecepatan feedwater 2.2 m/s dirancang untuk tidak menimbulkan resonansi atau getaran yang merusak pipa pemanas internal. Gagal memanaskan feedwater dari suhu terendah 40.4 C hingga 58.6 C menggunakan heating steam dengan tekanan paling rendah 0.213 bara Impingement Plate Tube Vibration Structural Failure Akibat hantaman uap bertahun-tahun (fatigue), las-lasan pengikat impingement plate bisa retak dan putus. Pelat yang lepas akan menimpa tube bundle dan bergetar sehingga terjadi impact. Tanpa pelat, uap menghantam tube secara langsung yang menyebabkan tube bergetar hebat hingga patah dalam waktu singkat. Terdengar suara clanking/banging atau rattling dari area inlet nozzle yang tidak beraturan; Muncul indikasi tube rupture tak lama setelah suara berisik terdengar. Membuka shell manhole saat unit shutdown. Periksa posisi impingement plate (apakah miring, hilang, atau jatuh di dasar shell) dan periksa kerusakan fisik pada tube di bawah nozzle; Jika memungkinkan, lakukan foto Radiographic Testing (RT) pada area nozzle saat operasi untuk melihat posisi pelat (jarang dilakukan tapi valid). Konstruksi pelat menggunakan Stainless Steel untuk ketahanan erosi; Inspeksi visual rutin kondisi internal shell sesuai Buku Manual Las ulang pelat dengan metode full penetration weld dan tambahkan stiffener atau penyangga yang lebih kokoh ke dinding shell, bukan ke tube; Tube yang sudah terkena hantaman langsung uap atau tertimpa pelat harus diganti atau di-plug karena kemungkinan besar sudah mengalami fatigue +Condensate Water Low Pressure Feedwater Heater 1 (LPH 1) Horizontal closed tubular type 3CO-H010 Memanaskan feedwater dari suhu terendah 40.4 C hingga 58.6 C menggunakan heating steam dengan tekanan paling rendah 0.213 bara Sisi proses (waterbox / channel head) dirancang menahan tekanan pompa kondensat 17.0 bar tanpa ada air yang merembes ke atmosfer luar. Gagal memanaskan feedwater dari suhu terendah 40.4 C hingga 58.6 C menggunakan heating steam dengan tekanan paling rendah 0.213 bara Water Box External Leakage - Process Medium Leakage Kegagalan penyegelan mengakibatkan hilangnya pressure boundary sehingga feedwater menyembur ke lingkungan atmosfer. Kondisi ini menciptakan safety hazard dan hilangnya demineralized water. Selain itu, paparan uap atau air panas yang bocor akan merusak isolasi termal (lagging), memicu korosi pada baut pengikat eksternal dan merusak peralatan instrumentasi. Terlihat steam plume yang keluar dari sela-sela isolasi/lagging di area tutup water box; Terdengar suara mendesis akibat air bertekanan keluar melewati celah sempit; Area lantai di bawah heater basah/tergenang.

Gagal memanaskan feedwater dari suhu terendah 40.4 C hingga 58.6 C menggunakan heating steam dengan tekanan paling rendah 0.213 bara Water Box External Leakage - Process Medium Looseness Hilangnya clamping force pada sambungan baut akibat kelonggaran menyebabkan tekanan kontak pada gasket turun di bawah batas seating stress. Kondisi ini menciptakan celah mikro yang menyebabkan feedwater blow-out ke atmosfer dan merusak isolasi termal. Jika tidak segera retorquing, kebocoran ini akan memicu flange face erosion serta korosi pada ulir baut. Terlihat steam weeping pada sambungan flange atau manhole; Suara desis halus dari area isolasi; Muncul karat atau kerak putih di sekitar mur/baut (stud bolts). Hammer test dengan mengetuk ringan pada baut (jika kondisi aman/dingin) untuk mendengar suara "mati" yang menandakan baut kendor; Cek apakah ada celah visual atau pergeseran pada mur Penggunaan Double Nuts atau Lock Washers dan prosedur pengencangan torsi bertahap saat pemasangan; Inspeksi visual rutin Lakukan retorquing dengan kunci torsi terkalibrasi saat unit beroperasi (jika prosedur Hot Bolting diizinkan dan aman) untuk mengembalikan gaya jepit gasket; Cek kekencangan seluruh baut manhole/flange secara periodik setiap 6 bulan atau setelah unit mengalami trip akibat siklus termal ekstrem +Condensate Water Low Pressure Feedwater Heater 1 (LPH 1) Horizontal closed tubular type 3CO-H010 Memanaskan feedwater dari suhu terendah 40.4 C hingga 58.6 C menggunakan heating steam dengan tekanan paling rendah 0.213 bara Sisi proses (waterbox / channel head) dirancang menahan tekanan pompa kondensat 17.0 bar tanpa ada air yang merembes ke atmosfer luar. Gagal memanaskan feedwater dari suhu terendah 40.4 C hingga 58.6 C menggunakan heating steam dengan tekanan paling rendah 0.213 bara Water Box External Leakage - Process Medium Flange deformation Deformasi fisik pada permukaan flange menyebabkan loss of flatness, sehingga gasket tidak menerima clamping force secara merata. Akibatnya, tercipta jalur kebocoran permanen di mana feedwater menyembur ke atmosfer, yang tidak dapat dihentikan dengan retorquing. Kebocoran uap/air pada sambungan flange meskipun baut sudah dikencangkan ulang; Pada kasus parah, mungkin terlihat celah yang tidak rata antar permukaan flange. Saat unit shutdown dan dibuka, ukur kerataan permukaan flange menggunakan straight edge dan feeler gauge. Jika celah melebihi toleransi, deformasi terkonfirmasi; Lakukan Blue Contact Check saat pemasangan untuk melihat area kontak yang hilang. Perhitungan ketebalan flange berdasarkan ASME Section VIII Div. 1; Prosedur pengencangan Pattern Star dan penggunaan kunci torsi terkalibrasi. Lakukan pembubutan ulang permukaan flange on-site untuk mengembalikan flatness; Cek dan atur ulang pipe support pada pipa inlet/outlet untuk memastikan tidak ada beban tarik/tekan berlebih yang membebani nozzle water box. +Condensate Water Low Pressure Feedwater Heater 1 (LPH 1) Horizontal closed tubular type 3CO-H010 Memanaskan feedwater dari suhu terendah 40.4 C hingga 58.6 C menggunakan heating steam dengan tekanan paling rendah 0.213 bara Material Tube sheet (ASTM A226 Cl.2) memiliki kekuatan menahan beban termal dan tekanan 17.0 bar tanpa retak di sudut radius internal.

Gagal menerima air dari LPH 2 dan gagal memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Shell External Leakage - Utility Medium Vibration Induced Fatigue Muncul fatigue crack di area pangkal nosel. Retakan tembus membocorkan uap dan kondensat panas. Selain kehilangan efisiensi pemanasan (suhu gagal mencapai 119.4 C), getaran yang dibiarkan bisa menyebabkan nosel patah sepenuhnya, memicu kondisi darurat trip. Terlihat getaran fisik yang kuat pada badan LPH 3 atau perpipaan yang terhubung dengannya. Kebocoran uap muncul di sambungan antara nosel pipa dan badan bejana. Lakukan pengukuran getaran (Vibration Analysis) pada badan LPH dan perpipaan terdekat. Lakukan uji PT/MT pada pangkal nosel yang bocor. Desain hanger (penggantung), penyangga (support), dan snubber pada perpipaan untuk meredam dan menahan getaran mekanis. Evaluasi ulang dan lakukan penyetelan (adjustment) pada sistem penyangga pipa uap ekstraksi. Jika resonansi aliran terdeteksi, modifikasi desain support (misalnya menambahkan sway brace atau tuned mass damper) untuk mematikan frekuensi getaran tersebut. +Condensate Water Low Pressure Feedwater Heater 3 (LPH 3) Horizontal closed tubular type 3CO-H030 Menerima air dari Low Pressure Feedwater Heater 2 dan memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Sisi shell (JIS SS400) yang berdiri sendiri di lantai turbin dirancang kedap untuk menahan uap pemanas bertekanan 2.13 bara dan suhu inlet uap hingga 237.0 °C pada kondisi desain 1.5 bar (g) hingga Full Vacuum. Gagal menerima air dari LPH 2 dan gagal memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Shell External Leakage - Utility Medium Corrosion Under Insulation - CUI Dinding luar shell berkarat dan menipis parah secara tersembunyi. Saat dinding tak lagi kuat menahan tekanan operasi 2 bar, pelat shell akan jebol membentuk lubang (pinhole atau robekan). Kehilangan uap ini langsung menurunkan kemampuan LPH 3 untuk mentransfer panas laten ke kondensat. Lapisan luar insulasi (lagging/cladding aluminium) terlihat penyok, bernoda karat, atau basah. Bau karat tajam di sekitar bejana. Lepaskan (strip-off) insulasi di area yang dicurigai (terutama di bagian bawah atau di sekitar nozzle yang menonjol). Lakukan pembersihan sikat kawat dan ukur sisa ketebalan dinding dengan UT. Lapisan cat anti-karat berkinerja tinggi pada permukaan luar bejana sebelum dibungkus insulasi kedap air. Buang seluruh insulasi basah, sandblast permukaan yang berkarat, lakukan penambalan las jika sudah sangat tipis, dan lapisi ulang dengan cat pelindung khusus suhu tinggi; Bungkus kembali LPH 3 menggunakan material insulasi yang hidrofobik (menolak air) seperti Aerogel untuk mencegah air terperangkap di masa depan. +Condensate Water Low Pressure Feedwater Heater 3 (LPH 3) Horizontal closed tubular type 3CO-H030 Menerima air dari Low Pressure Feedwater Heater 2 dan memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Sisi shell (JIS SS400) yang berdiri sendiri di lantai turbin dirancang kedap untuk menahan uap pemanas bertekanan 2.13 bara dan suhu inlet uap hingga 237.0 °C pada kondisi desain 1.5 bar (g) hingga Full Vacuum. Gagal menerima air dari LPH 2 dan gagal memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Shell External Leakage - Utility Medium Erosion of shell inside near inlet nozzle Penipisan lokal yang sangat parah di cincin sekitar nosel inlet. Jika berlubang, sebagian besar energi uap pemanas akan bocor langsung ke lingkungan sebelum sempat menyebar ke seluruh bundel tabung. Fungsi menaikkan suhu 22.3 C (dari 97.1 ke 119.4) akan gagal total. Kebocoran mendesis atau semburan uap yang keluar tepat dari celah antara flange pipa ekstraksi dan permukaan shell LPH 3. Lakukan Ultrasonic Thickness Measurement (UT) dengan pola melingkar rapat (radius 1-2 meter) di sekeliling area nosel masuk uap untuk mendeteksi profil keausan. Desain annular space (ruang kosong keliling) yang cukup besar di area nosel masuk untuk menurunkan kecepatan fluida secara aman sebelum bersentuhan dengan tabung atau dinding dalam. Lakukan perbaikan las tebal (weld buildup) pada area yang tererosi. Periksa sistem pembuangan air (steam trap/drain) pada jalur perpipaan ekstraksi sebelum LPH 3; pastikan uap yang masuk dijaga sekering mungkin untuk meminimalkan dampak erosi butiran air. +Condensate Water Low Pressure Feedwater Heater 3 (LPH 3) Horizontal closed tubular type 3CO-H030 Menerima air dari Low Pressure Feedwater Heater 2 dan memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Material tube Carbon Steel (ASTM A556M Gr.B2) menahan perbedaan tekanan antara sisi tube dan sisi shell untuk mencegah kebocoran internal antar-fluida. Gagal menerima air dari LPH 2 dan gagal memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Tube Internal Leakage Tube Vibration Dinding tabung menipis dan akhirnya pecah/patah. Air kondensat bertekanan bocor membanjiri shell LPH 3. Level air di shell naik tak terkendali, menenggelamkan tabung-tabung lain sehingga transfer panas dari uap terhenti. Suhu kondensat keluar akan jauh di bawah target 119.4 C. Terdengar suara dengungan keras atau benturan logam dari dalam LPH. Level air di shell melonjak tiba-tiba, diikuti bukaan katup drain darurat ke 100%. Lakukan Eddy Current Test (ECT) saat overhaul. Sinyal ECT akan menunjukkan keausan berbentuk cincin (ring wear) tepat di lokasi baffle atau cacat benturan datar (flat spots) di area mid-span Perhitungan jarak bentang penyangga (baffle spacing) sesuai standar TEMA untuk menghindari frekuensi resonansi. Sisipkan anti-vibration tube stakes di antara barisan tabung yang longgar untuk mengunci pergerakan mekanisnya tanpa perlu mematikan (mem-plug) tabung tersebut. +Condensate Water Low Pressure Feedwater Heater 3 (LPH 3) Horizontal closed tubular type 3CO-H030 Menerima air dari Low Pressure Feedwater Heater 2 dan memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Material tube Carbon Steel (ASTM A556M Gr.B2) menahan perbedaan tekanan antara sisi tube dan sisi shell untuk mencegah kebocoran internal antar-fluida. Gagal menerima air dari LPH 2 dan gagal memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Tube Internal Leakage Steam Impingement Penipisan dinding luar tabung menyebabkan tabung meledak (burst). Kebocoran membanjiri shell dan mematikan fungsi pemanasan. Jika tabung ini di-plug, luas area pemanasan menyusut, membuat LPH 3 semakin sulit mencapai 119.4 C. Kebocoran internal yang selalu berpusat di lokasi spesifik: barisan tabung terluar yang berhadapan langsung dengan nozzle uap masuk Inspeksi visual internal (menggunakan borescope) untuk melihat kondisi pelat pelindung (impingement plate). ECT akan mengkonfirmasi penipisan dari sisi OD tabung. Pemasangan Impingement Plate tebal di depan nosel inlet uap. Ganti tabung-tabung baris terluar yang rentan dengan Solid Dummy Rods (batang baja pejal). Batang ini akan bertindak sebagai perisai permanen yang menyerap energi hantaman uap tanpa risiko bocor, melindungi tabung kondensat aktif di baliknya. +Condensate Water Low Pressure Feedwater Heater 3 (LPH 3) Horizontal closed tubular type 3CO-H030 Menerima air dari Low Pressure Feedwater Heater 2 dan memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Material tube Carbon Steel (ASTM A556M Gr.B2) menahan perbedaan tekanan antara sisi tube dan sisi shell untuk mencegah kebocoran internal antar-fluida. Gagal menerima air dari LPH 2 dan gagal memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Tube Internal Leakage Loss of tube expansion Tercipta celah mikroskopis di sambungan. Kondensat merembes pelan (weeping) ke dalam shell. Meski perlahan, kebocoran ini menurunkan vakum/tekanan shell secara gradual dan mengurangi massa air yang dikirim ke sistem selanjutnya, mengganggu efisiensi termal LPH 3. Kenaikan parameter Make-up Water unit yang sangat pelan, TTD memburuk perlahan. Saat offline dan LPH dibuka, lakukan uji tekan dari sisi shell (atau vakum) dan semprotkan air sabun di muka tube sheet. Celah yang longgar akan menghasilkan gelembung. Desain lubang tube sheet beralur (grooved holes) untuk mengunci tabung saat di-roll. Lakukan proses Re-rolling (pemekaran ulang) menggunakan tube expander hidrolik pada sambungan-sambungan yang longgar untuk mengembalikan kerapatannya tanpa perlu mem-plug tabung. +Condensate Water Low Pressure Feedwater Heater 3 (LPH 3) Horizontal closed tubular type 3CO-H030 Menerima air dari Low Pressure Feedwater Heater 2 dan memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Material tube Carbon Steel (ASTM A556M Gr.B2) menahan perbedaan tekanan antara sisi tube dan sisi shell untuk mencegah kebocoran internal antar-fluida. Gagal menerima air dari LPH 2 dan gagal memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Tube Internal Leakage Stress Corrosion Cracking (SCC) Tabung menjadi sangat rapuh dan retak tak terprediksi. Kebocoran terjadi secara acak dan masif. HPH 3 terpaksa sering diisolasi untuk plugging. Akumulasi plugging memotong luas penampang perpindahan panas secara permanen, mengunci suhu kondensat jauh di bawah 119.4 C seumur hidup heater. Sejarah kebocoran tabung yang tinggi, tersebar acak (tidak mengelompok di satu area), dikonfirmasi dengan catatan riwayat kimia air (AVT) yang sering deviasi (misal oksigen tinggi). Cabut satu sampel tabung yang bocor (tube pull-out) dan kirim ke laboratorium metalurgi. Analisis struktur mikro akan menunjukkan retakan bercabang khas SCC. Proses anil pelepas tegangan (stress-relief annealing) pada tabung U-bend saat pabrikasi. Kontrol ketat Dissolved Oxygen di kondensor. Tindakan segera: Perketat injeksi bahan kimia pengikat oksigen (Oxygen Scavenger) dan kontrol pH kondensat. Solusi jangka panjang: Jika SCC sudah merajalela, Engineering harus merencanakan Retubing LPH 3 menggunakan material yang imun terhadap SCC amonia (seperti Stainless Steel 304/316 atau Titanium). +Condensate Water Low Pressure Feedwater Heater 3 (LPH 3) Horizontal closed tubular type 3CO-H030 Menerima air dari Low Pressure Feedwater Heater 2 dan memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas.

Gagal menerima air dari LPH 2 dan gagal memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Tube Internal Leakage Inlet End Erosion Dinding dalam tabung terkikis habis dari dalam. Tabung bocor di area pangkal. Air menyeberang ke shell. Ketika tabung ini di-plug, debit air akan beralih ke tabung di sebelahnya, menaikkan kecepatan lokal dan memicu erosi inlet beruntun. Kapasitas pemanasan hancur. Kebocoran selalu terlokalisasi hanya pada beberapa inci pertama dari muka tube sheet di area inlet/masuk. Inspeksi visual pada muka tube sheet menunjukkan mulut tabung yang tajam, tidak beraturan, atau menipis parah. Pembatasan kecepatan aliran kondensat (< 2.0 - 2.4 m/s) dan desain muka tabung yang rata/meruncing (flushed/flared). Pasang Inlet Sleeves (selongsong pelindung dari plastik tahan panas atau stainless steel) sepanjang 20-30 cm ke dalam mulut tabung yang masih sehat. Selongsong ini akan menanggung beban erosi, melindungi dinding tabung asli. +Condensate Water Low Pressure Feedwater Heater 3 (LPH 3) Horizontal closed tubular type 3CO-H030 Menerima air dari Low Pressure Feedwater Heater 2 dan memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Material tube Carbon Steel (ASTM A556M Gr.B2) menahan perbedaan tekanan antara sisi tube dan sisi shell untuk mencegah kebocoran internal antar-fluida. Gagal menerima air dari LPH 2 dan gagal memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Tube Sheet Internal Leakage Galvanic Corrosion Material tube sheet di sekitar lubang tabung terkikis parah menjadi keropos. Sambungan tabung kehilangan tumpuan, melonggar, dan membocorkan air kondensat secara masif ke shell. Kerusakan tube sheet sangat fatal karena tidak bisa diselesaikan hanya dengan mem-plug tabung. Terlihat lubang-lubang korosi sumuran (pitting) yang mengelilingi batas antara dinding tabung dan plat tube sheet di sisi Water Box. Inspeksi visual jarak dekat dan Dye Penetrant Testing (PT) pada tube sheet setelah dibersihkan. Cek parameter konduktivitas kondensat. Pemilihan material dengan beda potensial galvanik sekecil mungkin, atau penggunaan plat cladding tahan korosi di muka tube sheet. Terapkan pelapisan epoksi khusus suhu tinggi (epoxy coating / cladding) pada seluruh permukaan tube sheet sisi Water Box. Lapisan ini berfungsi sebagai isolator elektrik yang memutus jalur kontak elektrolit antara kedua logam berbeda, menghentikan laju korosi galvanik secara instan. +Condensate Water Low Pressure Feedwater Heater 3 (LPH 3) Horizontal closed tubular type 3CO-H030 Menerima air dari Low Pressure Feedwater Heater 2 dan memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas.

Gagal menerima air dari LPH 2 dan gagal memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Tube Sheet Internal Leakage Inlet End Erosion Dinding dalam tabung terkikis habis dari dalam. Tabung bocor di area pangkal. Air menyeberang ke shell. Ketika tabung ini di-plug, debit air akan beralih ke tabung di sebelahnya, menaikkan kecepatan lokal dan memicu erosi inlet beruntun. Kapasitas pemanasan hancur. Kebocoran selalu terlokalisasi hanya pada beberapa inci pertama dari muka tube sheet di area inlet/masuk. Inspeksi visual pada muka tube sheet menunjukkan mulut tabung yang tajam, tidak beraturan, atau menipis parah. Pembatasan kecepatan aliran kondensat (< 2.0 - 2.4 m/s) dan desain muka tabung yang rata/meruncing (flushed/flared). Pasang Inlet Sleeves (selongsong pelindung dari plastik tahan panas atau stainless steel) sepanjang 20-30 cm ke dalam mulut tabung yang masih sehat. Selongsong ini akan menanggung beban erosi, melindungi dinding tabung asli. +Condensate Water Low Pressure Feedwater Heater 3 (LPH 3) Horizontal closed tubular type 3CO-H030 Menerima air dari Low Pressure Feedwater Heater 2 dan memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Kecepatan feedwater dijaga pada 2.0 m/s agar mengalir lancar menyapu area pemanas seluas 930 m² tanpa hambatan di dalam tube. Gagal menerima air dari LPH 2 dan gagal memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Tube Plugged/Choked Foreign Material Ingress Puluhan hingga ratusan mulut tabung tertutup rapat secara mendadak. Debit air terhalang masuk; Area aktif perpindahan panas (A) menyusut drastis. LPH 3 kehilangan luasan untuk memanaskan air, sehingga target suhu 119.4 C tidak akan tercapai. Sisa aliran kondensat yang masih dipompa akan memaksa masuk ke tabung-tabung yang tidak tersumbat, menaikkan kecepatan lokal secara ekstrem dan memicu kerusakan erosi ujung tabung (Inlet End Erosion). Kenaikan Differential Pressure (Delta P) sisi kondensat yang terjadi secara mendadak (step change), biasanya langsung terlihat saat unit dioperasikan (sinkronisasi) paska overhaul atau pemeliharaan perpipaan. Suhu outlet LPH 3 drop mendadak. Isolasi heater, buka penutup Manway/Water Box, dan lakukan inspeksi visual langsung pada inlet tube sheet. Strainer pada isapan Condensate Extraction Pump (CEP) untuk menyaring benda besar. Pembersihan Manual: Ambil benda asing secara manual dari Water Box; Wajibkan penerapan Foreign Material Exclusion (FME) yang ketat selama outage. Gunakan penutup flensa (blind/cover) merah saat pipa terbuka, dan lakukan inspeksi akhir berlapis (dokumentasi foto) sebelum menutup bejana tekan +Condensate Water Low Pressure Feedwater Heater 3 (LPH 3) Horizontal closed tubular type 3CO-H030 Menerima air dari Low Pressure Feedwater Heater 2 dan memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Kecepatan feedwater dijaga pada 2.0 m/s agar mengalir lancar menyapu area pemanas seluas 930 m² tanpa hambatan di dalam tube. Gagal menerima air dari LPH 2 dan gagal memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Tube Plugged/Choked Crud Deposition Kemampuan logam tabung untuk mentransfer panas laten dari uap ke air kondensat (U-value) merosot tajam. Laju penyerapan panas melambat, sehingga air kondensat hanya lewat tanpa menyerap cukup energi. Suhu keluar akan stagnan jauh di bawah 119.4 C (misal hanya mencapai 105-110 C), memaksa turbin membuang lebih banyak uap untuk kompensasi. Parameter Terminal Temperature Difference (TTD) memburuk secara perlahan. Kenaikan Delta P sisi kondensat terjadi sangat lambat dalam hitungan bulan atau tahun. Buka LPH 3 saat offline dan lakukan inspeksi menggunakan borescope ke dalam tabung. Akan terlihat lapisan deposit berwarna hitam atau coklat kemerahan. Analisis tren kandungan besi (Total Iron) pada sampel air kondensat. Pengendalian kimia air (AVT - All Volatile Treatment) dengan injeksi amonia dan agen pengikat oksigen untuk menjaga pH kondensat (biasanya sekitar 9.2 - 9.6) guna menekan laju korosi besi. Jadwalkan pembersihan tabung mekanis secara rutin saat Major Overhaul menggunakan High-Pressure Water Jetting atau penembakan peluru bertekanan air (dart/bullet cleaning) untuk merontokkan kerak magnetit dan mengembalikan koefisien perpindahan panas. +Condensate Water Low Pressure Feedwater Heater 3 (LPH 3) Horizontal closed tubular type 3CO-H030 Menerima air dari Low Pressure Feedwater Heater 2 dan memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Kecepatan feedwater dijaga pada 2.0 m/s agar mengalir lancar menyapu area pemanas seluas 930 m² tanpa hambatan di dalam tube. Gagal menerima air dari LPH 2 dan gagal memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Tube Plugged/Choked Scaling Efisiensi perpindahan panas hancur seketika. Pemblokiran fisik ini tidak hanya menggagalkan LPH 3 mencapai suhu 119.4 C, tetapi jika terlalu tebal, dapat membatasi debit total aliran kondensat yang menuju ke Deaerator, yang berisiko membatasi beban maksimum unit (MW derating). Penurunan drastis pada suhu outlet LPH 3 yang hampir selalu didahului oleh rentetan alarm parameter kimia air: Cation Conductivity tinggi, Silika tinggi, atau Sodium tinggi di kondensat. Ambil sampel kerokan endapan dari dalam tabung saat offline dan lakukan uji komposisi laboratorium (XRF/XRD). Jika deposit didominasi oleh Ca, Mg, atau Si, maka pembentukan kerak mineral terkonfirmasi. Keberadaan Condensate Polishing Plant (CPP) yang berfungsi menyaring ion-ion kontaminan jika terjadi kebocoran kondensor, memberikan waktu bagi operator untuk bertindak sebelum kerak terbentuk di LPH. Chemical Cleaning: Kerak mineral silika atau sulfat sangat keras dan seringkali tidak bisa dibersihkan hanya dengan semprotan air mekanis. Diperlukan proses Chemical Cleaning (pencucian asam dengan inhibitor khusus) untuk melarutkan kerak tanpa merusak logam tabung asli; Segera atasi akar masalah utamanya, yaitu temukan dan sumbat (plug) tabung kondensor yang bocor penyebab masuknya air laut/air mentah. +Condensate Water Low Pressure Feedwater Heater 3 (LPH 3) Horizontal closed tubular type 3CO-H030 Menerima air dari Low Pressure Feedwater Heater 2 dan memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Integritas struktural (Tube, Shell, Tubesheet) didesain aman menahan suhu operasi desain 128.0 °C (Shell/Tube) dan 237.0 °C pada area steam inlet. Gagal menerima air dari LPH 2 dan gagal memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Shell Structural Deficiency Corrosion Air kondensat bersuhu 97.1 C yang baru masuk dari LPH 2 langsung menerobos (bypass) melewati lubang korosi tersebut menuju nosel outlet, tanpa pernah masuk ke dalam U-tubes (tabung pemanas). Waktu kontak perpindahan panas hilang. Suhu kondensat yang keluar dari LPH 3 akan jauh dari target 119.4 C (kemungkinan besar tetap di kisaran 97-100 C). Penurunan Differential Pressure ($\Delta P$) sisi kondensat secara mendadak atau bertahap (karena air menemukan jalur bebas hambatan).Suhu Feedwater Outlet anjlok drastis (TTD memburuk ekstrem). Buka Manway Water Box saat offline dan lakukan inspeksi visual langsung pada pelat partisi dan lasannya. Desain pelat partisi menggunakan corrosion allowance (ketebalan ekstra) 3-6 mm. Lakukan perbaikan pengelasan (weld patching) pada pelat partisi yang berlubang. Untuk ketahanan permanen, terapkan Weld Overlay / Cladding menggunakan material Stainless Steel pada seluruh permukaan pelat partisi agar kebal terhadap FAC kondensat. +Condensate Water Low Pressure Feedwater Heater 3 (LPH 3) Horizontal closed tubular type 3CO-H030 Menerima air dari Low Pressure Feedwater Heater 2 dan memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Integritas struktural (Tube, Shell, Tubesheet) didesain aman menahan suhu operasi desain 128.0 °C (Shell/Tube) dan 237.0 °C pada area steam inlet. Gagal menerima air dari LPH 2 dan gagal memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Shell Structural Deficiency Excessive Thermal Stress Las-lasan penahan struktural internal (misal sambungan pelat partisi ke tube sheet, atau dudukan pelat impingement) patah/robek; Jika pelat partisi robek dari dudukannya, air kondensat akan bypass secara masif. Jika impingement plate yang robek, uap basah akan menghantam langsung tabung pemanas, merobeknya, dan membanjiri bejana dengan air dingin. Keduanya menggagalkan pencapaian suhu 119.4 C. Terdengar suara benturan logam keras (clanking / pinging) dari dalam bejana saat transien ganti beban atau start-up; Penurunan kinerja termal (suhu outlet) yang menetap setelah kejadian transient beban unit. Lakukan pengujian Dye Penetrant (PT) atau Magnetic Particle (MT) pada sambungan las pelat partisi ke muka tube sheet saat overhaul. Aturan operasi (SOP) yang membatasi Ramp Rate batas laju perubahan suhu (biasanya dibatasi maksimal ~100 C Tinjau ulang logika kontrol DCS. Otomatisasi katup uap utama atau pasang warming-up bypass valve kecil yang membuka perlahan untuk memastikan pemanasan logam berlangsung secara bertahap sebelum katup utama membuka penuh. +Condensate Water Low Pressure Feedwater Heater 3 (LPH 3) Horizontal closed tubular type 3CO-H030 Menerima air dari Low Pressure Feedwater Heater 2 dan memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Integritas struktural (Tube, Shell, Tubesheet) didesain aman menahan suhu operasi desain 128.0 °C (Shell/Tube) dan 237.0 °C pada area steam inlet. Gagal menerima air dari LPH 2 dan gagal memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Shell Structural Deficiency Over-Pressure Tekanan statis yang masif menekan Pass Partition Plate hingga melengkung bengkok (buckling). Gasket penyekat di bawahnya terdorong keluar atau jebol; Melengkungnya pelat menciptakan celah permanen selebar beberapa milimeter atau sentimeter antara pelat partisi dan Water Box Cover. Kondensat dingin kembali mengambil jalan pintas (menciptakan short circuit) langsung ke saluran keluar. Efisiensi pemanasan hancur, LPH 3 tidak mampu memanaskan hingga 119.4 C. Kejadian ini biasanya didahului oleh rentetan alarm High Pressure sisi Condensate atau operasi abnormal pompa CEP, yang segera diikuti oleh penurunan efisiensi termal LPH 3 secara permanen. Gunakan Straight Edge (penggaris perata baja) dan Feeler Gauge untuk mengukur tingkat kelengkungan (deflection / flatness) pada muka Pass Partition Plate saat bejana dibuka. Pemasangan Safety Relief Valve (SRV) pada Water Box sisi air kondensat dan di badan shell. Jika pelat sudah melengkung, ganti plat atau tarik kembali menggunakan pemanasan, lalu las pelat penguat melintang (stiffener ribs/gussets) di belakang pelat partisi untuk menambah kekakuan struktural (rigidity) menahan gaya tekan; Lakukan kalibrasi (pop test) wajib tahunan pada SRV LPH 3. +Condensate Water Low Pressure Feedwater Heater 3 (LPH 3) Horizontal closed tubular type 3CO-H030 Menerima air dari Low Pressure Feedwater Heater 2 dan memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Integritas struktural (Tube, Shell, Tubesheet) didesain aman menahan suhu operasi desain 128.0 °C (Shell/Tube) dan 237.0 °C pada area steam inlet. Gagal menerima air dari LPH 2 dan gagal memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Tube Sheet Structural Deficiency Fatigue Failure Baffle plate (pelat pengarah uap) patah dan runtuh sebagian di dalam shell; Uap pemanas tidak lagi mengalir melintang secara zig-zag (aliran cross-flow hilang), melainkan mengalir lurus ke outlet, membuang energi panas ke kondensor secara sia-sia; Tabung kondensat kehilangan tumpuan penyangga, memicu getaran hebat yang berujung pada pecahnya tabung. Kedua kondisi ini memastikan LPH 3 gagal menaikkan suhu air ke 119.4 C. Tren getaran (vibration signature) pada struktur bejana meningkat tajam; Diikuti oleh frekuensi tube leak (kebocoran tabung) yang menumpuk di zona penyangga yang sama secara berulang. Inspeksi internal menggunakan Borescope bersumbu panjang dari nozel uap atau drain untuk memeriksa integritas tie rods dan susunan baffles di dalam shell. Desain ketebalan struktural baffles dan tie rods yang memiliki margin umur lelah (fatigue life) di atas 25-30 tahun operasi baseload. Operasi unit yang sering berayun (load cycling / hunting) mempercepat umur lelah struktur. Optimalkan kestabilan kontrol beban di sistem Governor; Jika kerusakan baffle internal sudah terdeteksi dan luas, perbaikan in-situ seringkali tidak ekonomis. Rekomendasi teknis tertingginya adalah merencanakan Retubing total LPH 3 dengan desain bundle baru yang menggunakan penyangga ekstra (seperti desain double segmental baffles). +Condensate Water Low Pressure Feedwater Heater 3 (LPH 3) Horizontal closed tubular type 3CO-H030 Menerima air dari Low Pressure Feedwater Heater 2 dan memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Kecepatan feedwater 2.0 m/s dan impak dinamik dari debit uap pemanas 61.085 kg/jam dikontrol agar tidak memicu getaran yang merusak tube Carbon Steel. Gagal menerima air dari LPH 2 dan gagal memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Shell Tube Vibration High steam velocity on shell side Tabung baris terluar (yang berhadapan langsung dengan aliran uap utama) mengalami tegangan lengkung (bending stress) dan membentur tabung di sebelahnya atau bergesekan dengan baffle; Tabung luar bocor dan harus di-plug. Area pemanasan berkurang. Jika sering terjadi, LPH 3 akan kehilangan persentase luasan tabung yang signifikan, memaksanya beroperasi di bawah target suhu 119.4 C. Kebocoran tabung selalu terdeteksi dan terpusat di barisan terluar bundel tabung (periphery tubes) Pemetaan tabung bocor (tube plugging map) akan menunjukkan pola cincin luar. Inspeksi Eddy Current Test (ECT) menunjukkan keausan dari sisi luar (OD) tabung. Pembatasan kecepatan uap ekstraksi pada desain nosel dan pemasangan jarak aman (escape lane) antar tabung. Ganti tabung baris terluar yang paling sering bocor dengan Solid Dummy Rods (batang baja pejal). Batang pejal ini tahan terhadap getaran kinetik dan akan bertindak sebagai "pagar pelindung" permanen bagi tabung-tabung aktif di barisan dalamnya tanpa mengurangi area pemanasan lebih lanjut. +Condensate Water Low Pressure Feedwater Heater 3 (LPH 3) Horizontal closed tubular type 3CO-H030 Menerima air dari Low Pressure Feedwater Heater 2 dan memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Kecepatan feedwater 2.0 m/s dan impak dinamik dari debit uap pemanas 61.085 kg/jam dikontrol agar tidak memicu getaran yang merusak tube Carbon Steel. Gagal menerima air dari LPH 2 dan gagal memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Shell Tube Vibration Fluidelastic whirring Terjadi benturan antar-tabung di tengah bentang penyangga (mid-span clashing). Tabung bisa gepeng atau robek masif dalam hitungan jam atau hari; Kebocoran internal berskala besar. Shell kebanjiran air kondensat secara instan. Fungsi pemanasan LPH 3 mati total (suhu drop ke 97 C). Heater harus segera diisolasi dan di-bypass untuk menyelamatkan turbin dari risiko kembalinya air (water induction). Terdengar suara dengungan, raungan, atau benturan keras bergemuruh dari dalam badan shell LPH 3. Level air shell melonjak memicu alarm High-High, dan bukaan katup drain darurat langsung 100%. Saat bundle ditarik, akan terlihat jejak benturan datar (flat spots) yang sangat jelas di bagian tengah tabung (di antara dua pelat baffle). Perhitungan standar TEMA untuk jarak maksimal antar penyangga (unsupported span length) agar frekuensi alami tabung tetap tinggi. Hindari operasi unit pada beban MW tertentu yang memicu titik kritis aliran ini (exclusion zone). Pasang Tube Stakes (pasak peredam getaran berupa pelat strip pipih) yang disisipkan di antara baris tabung tepat di tengah bentang untuk mematikan ayunan orbital tersebut. +Condensate Water Low Pressure Feedwater Heater 3 (LPH 3) Horizontal closed tubular type 3CO-H030 Menerima air dari Low Pressure Feedwater Heater 2 dan memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Kecepatan feedwater 2.0 m/s dan impak dinamik dari debit uap pemanas 61.085 kg/jam dikontrol agar tidak memicu getaran yang merusak tube Carbon Steel. Gagal menerima air dari LPH 2 dan gagal memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Shell Tube Vibration Vortex shedding Tabung bergetar hebat tegak lurus terhadap arah aliran uap. Mengakibatkan kelelahan material (fatigue) di area lasan tube-to-tubesheet atau keausan di penyangga; Mengakibatkan tube leak. Penutupan tabung (plugging) yang berkelanjutan akan mereduksi luas perpindahan panas LPH 3 perlahan-lahan, hingga akhirnya laju kenaikan suhu gagal mencapai 119.4 C. Kadang memicu kebisingan akustik (acoustic resonance) yang memekakkan telinga. Kebisingan bernada murni (howling / pure tone noise) yang sangat nyaring terdengar di sekitar heater pada beban spesifik turbin. Lakukan analisis spektrum getaran di luar badan shell. Frekuensi puncak (peak frequency) akan terukur sangat spesifik dan sinkron dengan beban aliran uap tertentu. Desain pabrikan memastikan frekuensi alami tabung minimal 20% lebih tinggi dari perkiraan frekuensi vortex shedding. Jika masalah utamanya adalah resonansi akustik (kebisingan udara di shell yang merusak tabung), pasang pelat peredam akustik (deresonating baffles) secara paralel dengan arah aliran uap untuk memecah gelombang suara di dalam shell. +Condensate Water Low Pressure Feedwater Heater 3 (LPH 3) Horizontal closed tubular type 3CO-H030 Menerima air dari Low Pressure Feedwater Heater 2 dan memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Kecepatan feedwater 2.0 m/s dan impak dinamik dari debit uap pemanas 61.085 kg/jam dikontrol agar tidak memicu getaran yang merusak tube Carbon Steel. Gagal menerima air dari LPH 2 dan gagal memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Tube Support Plate Tube Vibration Baffle gap is too far Tabung terkikis habis secara melingkar karena bergesekan dengan ujung tajam pelat baffle (fretting wear); Terbentuk lubang jarum (pinhole) atau retakan melingkar pada tabung di titik penyangga. Air bocor mematikan uap. Plugging wajib dilakukan, lagi-lagi mengurangi kapasitas LPH 3 untuk memanaskan air kondensat dari 97.1 C ke 119.4 C. Tren kebocoran lambat, ditandai dengan sedikit kenaikan beban drain valve LPH 3. Inspeksi Eddy Current Test (ECT) akan memperlihatkan grafik pelemahan dinding yang sangat khas: berbentuk cincin penyusutan (ring wear) tepat di interval jarak setiap pelat baffle. Batasan celah toleransi lubang standar TEMA (biasanya hanya 0.4 mm hingga 0.8 mm lebih besar dari diameter luar tabung). Gunakan metode Tube Staking atau kembangkan sedikit diameter tabung secara hidrolik hanya pada titik-titik penyangga (localized expansion) agar tabung kembali terkunci erat ke dalam lubang baffle yang sudah membesar tersebut. +Condensate Water Low Pressure Feedwater Heater 3 (LPH 3) Horizontal closed tubular type 3CO-H030 Menerima air dari Low Pressure Feedwater Heater 2 dan memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Kecepatan feedwater 2.0 m/s dan impak dinamik dari debit uap pemanas 61.085 kg/jam dikontrol agar tidak memicu getaran yang merusak tube Carbon Steel. Gagal menerima air dari LPH 2 dan gagal memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Impingement Plate Tube Vibration High Inlet Velocity Tabung bocor di titik masuk uap. Uap pemanas yang seharusnya menyebar justru terkondensasi awal oleh air dingin bocoran di depan pintu masuk. Suhu keluaran LPH 3 akan jauh dari 119.4 C. Tabung yang dikorbankan (plugged) berada di area perpindahan panas paling prima. Kebocoran tabung selalu berkumpul dalam area yang sejajar secara visual ("line of sight") dengan arah nosel uap masuk ekstraksi LP turbin. Buka LPH dan lakukan inspeksi visual di area bawah nosel masuk. Pastikan eksistensi dan integritas Impingement Plate. Impingement Plate berbahan baja tahan karat yang tebal. Las kembali pelat pelindung (Impingement Plate) yang baru, lebih tebal, dan berukuran lebih luas dari proyeksi area nosel. Jika ruang internal tidak memungkinkan, ganti baris pertama tabung pemanas di bawah nosel dengan batang baja murni (solid rods). +Condensate Water Low Pressure Feedwater Heater 3 (LPH 3) Horizontal closed tubular type 3CO-H030 Menerima air dari Low Pressure Feedwater Heater 2 dan memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Kecepatan feedwater 2.0 m/s dan impak dinamik dari debit uap pemanas 61.085 kg/jam dikontrol agar tidak memicu getaran yang merusak tube Carbon Steel. Gagal menerima air dari LPH 2 dan gagal memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Impingement Plate Tube Vibration Structural Failure Saat penyangga hancur, jarak bentang tabung yang tidak tersangga (unsupported span length) menjadi dua kali lipat lebih panjang. Frekuensi alami tabung anjlok secara drastis; Tabung yang kehilangan tumpuan ini menjadi sangat lentur dan bergetar hebat tak terkendali meskipun pada kecepatan uap normal. Ini memicu kebocoran tabung massal secara tiba-tiba. LPH 3 harus dimatikan total (bypass 100%). Pemanasan 97.1 C ke 119.4 C gagal seketika, dan efisiensi termal Low Pressure System pembangkit akan memburuk tajam. Kejadian dramatis. Suara dentuman dari dalam bejana diikuti peningkatan drastis indikasi vibration secara lokal, lalu alarm trip level air High-High secara seketika. Inspeksi visual menyeluruh (seringkali mengharuskan penarikan bundel / bundle pulling) untuk melihat keruntuhan struktur kerangka internal LPH. Desain Tie rods dan spacers berbahan tahan korosi dengan perhitungan tegangan yang tinggi. Kerusakan struktural internal (runtuhnya baffle atau tie rods) hampir mustahil diperbaiki dengan menambal las dari celah sempit. Solusi rekayasa yang direkomendasikan adalah melakukan Retubing atau penggantian unit LPH 3 secara keseluruhan, mengingat integritas rangka pendukungnya sudah hancur. +Condensate Water Low Pressure Feedwater Heater 3 (LPH 3) Horizontal closed tubular type 3CO-H030 Menerima air dari Low Pressure Feedwater Heater 2 dan memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas.

Gagal menerima air dari LPH 2 dan gagal memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Enclosing Plate Flashing Subcooler Leakage on Enclosing Plate Semburan flashing jet ini menghantam langsung permukaan luar (OD) tabung-tabung subcooler yang berada tepat di depan celah kebocoran pelat. Tabung mengalami erosi impak dan kavitasi ekstrem hingga terpotong/bocor dalam waktu yang sangat singkat. Suhu DCA (Drain Cooler Approach) memburuk secara drastis (suhu drain keluar menjadi sangat panas); Riwayat kebocoran tabung (tube leak) yang sangat spesifik dan lokalis yang selalu berada di subcooler zone; Terdengar suara gemeretak keras seperti kelereng berjatuhan (cavitation noise) dari bagian bawah shell LPH 3. ECT pada tabung di zona bawah akan menunjukkan defek berupa penipisan dari sisi luar tabung (OD - Outer Diameter erosion), bukan dari dalam; Saat overhaul dan tabung terekspos, semprotkan udara bertekanan dari saluran drain/shell luar, dan sapukan air sabun pada sepanjang las-lasan pelat shroud subcooler untuk menemukan titik retak/lubang tempat uap menerobos masuk. Penggunaan pelat pembungkus baja karbon ekstra tebal (>10 mm) dengan prosedur pengelasan penetrasi penuh (full penetration weld) untuk menahan perbedaan tekanan statis dan tegangan termal. Wajib mengelas (menambal) retakan pada pelat shroud subcooler; Jika retakan pada shroud berada di lokasi yang sangat sempit dan tidak terjangkau oleh tangkai las (welding torch), tindakan mitigasi terbaik adalah mem-plug tabung-tabung yang sudah rusak/terpotong di depan retakan tersebut, dan memasukkan batang baja pejal (Solid Dummy Rods) ke dalam tabung tersebut. +Condensate Water Low Pressure Feedwater Heater 3 (LPH 3) Horizontal closed tubular type 3CO-H030 Menerima air dari Low Pressure Feedwater Heater 2 dan memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Area waterbox/channel dirancang tertutup rapat agar feedwater bersuhu tinggi tidak merembes keluar ke area lantai turbin. Gagal menerima air dari LPH 2 dan gagal memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas. Water Box External Leakage - Process Medium Leakage Semburan air kondensat panas ke luar. Karena suhu outlet LPH 3 bisa mencapai 119.4 C (di atas titik didih air pada tekanan atmosfer 100 C), air yang bocor akan langsung menguap sebagian (flashing), menciptakan semburan jet campuran air panas dan uap yang membahayakan personel di sekitar; Kehilangan massa air kondensat akan menurunkan level Deaerator/Hotwell. Untuk menyelamatkan siklus, LPH 3 harus di-bypass. Terdengar suara mendesis keras atau terlihat kepulan uap/kabut air panas di area Water Box LPH 3; Peningkatan aliran Make-up Water ke kondensor karena sistem kehilangan air demin secara konstan. Lakukan inspeksi visual dari jarak aman ke area Water Box LPH 3. Jika kebocoran tertutup insulasi, air biasanya akan menetes dari bagian terendah insulasi header. Penggunaan gasket berkualitas tinggi (misal: Spiral Wound Gasket dengan pengisi Graphite atau PTFE) yang tahan terhadap fluktuasi tekanan dan suhu. Desain Pressure Seal pada manway bejana tekanan tinggi. Segera isolasi (tutup katup inlet dan outlet kondensat) dan bypass LPH 3; Ganti gasket dengan yang baru. Pastikan permukaan dudukan gasket (seating face) dibersihkan total dari sisa gasket lama sebelum memasang yang baru untuk mencegah kebocoran berulang. +Condensate Water Low Pressure Feedwater Heater 3 (LPH 3) Horizontal closed tubular type 3CO-H030 Menerima air dari Low Pressure Feedwater Heater 2 dan memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas.

Water Box External Leakage - Process Medium Looseness Tekanan jepit (clamping force) pada gasket berkurang. Celah mikro terbentuk. Air kondensat bertekanan merembes keluar; Kebocoran kecil awalnya tidak men-trip-kan sistem, namun lambat laun membesar. BFP/CEP harus memompa lebih banyak air. Muncul kerak putih atau noda karat (chemical deposits) yang menetes dari bawah baut atau di sela-sela flensa inlet/outlet kondensat; Rembesan air yang terlihat menetes perlahan ke lantai grating. Lakukan pengecekan kekencangan torsi (torque check) pada baut yang dicurigai (sesuaikan dengan prosedur keselamatan, terkadang hot-bolting tidak diizinkan pada tekanan tertentu). Prosedur pengencangan menggunakan kunci momen hidrolik (hydraulic torque wrench) dengan urutan menyilang (criss-cross pattern) standar mekanikal. Terapkan pemberian garis penanda (cat spidol/ tally marks) pada mur dan baut stud setelah pengencangan final saat outage. Operator yang patroli cukup melihat apakah garis cat tersebut bergeser untuk mendeteksi kelonggaran secara dini; Lakukan re-torquing (pengencangan ulang) setelah unit beroperasi stabil selama 24-48 jam paska overhaul untuk mengatasi relaksasi termal awal. +Condensate Water Low Pressure Feedwater Heater 3 (LPH 3) Horizontal closed tubular type 3CO-H030 Menerima air dari Low Pressure Feedwater Heater 2 dan memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas.

Water Box External Leakage - Process Medium Flange deformation Terjadi celah struktural permanen antara dua permukaan logam yang seharusnya saling menjepit gasket; Kebocoran menjadi sangat persisten (stubborn leak). Meskipun gasket diganti berkali-kali, saat tekanan air kondensat masuk, bejana akan langsung bocor hebat. LPH 3 tidak akan pernah bisa dioperasikan (selalu di-bypass). Riwayat kebocoran eksternal yang berulang secara konstan pada titik koordinat yang sama persis di sekeliling flensa, tak lama setelah gasket baru dipasang dan unit diberi tekanan. Setelah LPH 3 diisolasi dan manway dibuka, bersihkan permukaan flange; Gunakan Straight Edge (penggaris perata baja presisi) dan Feeler Gauge (pengukur celah) untuk memetakan kerataan (flatness) dan kesejajaran (parallelism) di seluruh permukaan melingkar flensa. Ketebalan flensa baja tempa (forged steel) didesain sangat masif (bisa setebal belasan sentimeter) untuk menahan momen tekuk dari baut dan tekanan internal. Gasket tidak akan pernah menyelesaikan masalah flensa yang melengkung. Tindakan korektif wajibnya adalah mendatangkan alat bubut portabel (in-situ flange facer machine) untuk membubut/meratakan ulang (machining) permukaan flange; Pastikan operator selalu membuka katup air kondensat perlahan dan melakukan pembuangan udara (venting) yang sempurna saat mengisi Water Box untuk mencegah thermal/pressure shock yang membengkokkan penutup bejana. +Condensate Water Low Pressure Feedwater Heater 3 (LPH 3) Horizontal closed tubular type 3CO-H030 Menerima air dari Low Pressure Feedwater Heater 2 dan memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas.

Uap pemanas langsung mati (terkondensasi prematur), level shell melonjak tajam, dan LPH 3 terpaksa harus di-bypass total. Fungsi pemanasan ke 119.4 C gagal 100%. Kenaikan level kondensat di sisi shell secara tiba-tiba dan persisten (sering memicu alarm High-High Level); Suhu air keluar (Feedwater Outlet) anjlok seketika; Perbedaan mendasar dengan tube leak: volume kebocoran ini biasanya jauh lebih masif dan tidak bisa diatasi dengan menyumbat (plugging) tabung. Isolasi LPH 3, buka penutup Water Box, dan bersihkan area sudut internal tube plate; Lakukan pengujian Dye Penetrant (PT) atau Magnetic Particle (MT) secara melingkar penuh di sepanjang sudut transisi (corner radius) untuk memetakan panjang dan arah retakan. Desain batas radius transisi minimal sesuai standar bejana tekan (ASME BPVC) untuk mendistribusikan gaya/tegangan; Penerapan Post-Weld Heat Treatment (PWHT) di pabrik untuk menghilangkan tegangan sisa (residual stress) pada area lasan struktural tebal. Jika retakan masih sangat dangkal, lakukan blend grinding (penggerindaan halus) untuk menghilangkan retak sekaligus membuat sudut radius menjadi lebih landai guna mengurangi konsentrasi tegangan; Lakukan Weld Repair dan wajib diikuti dengan pemanasan pelepas tegangan lokal (Local PWHT); Disiplinkan operator untuk mematuhi kurva Ramp Rate (batas laju pemanasan/pendinginan) saat start-up dan shutdown LPH 3 untuk menghindari tegangan termal kejut (thermal shock) di masa depan. +Condensate Water Low Pressure Feedwater Heater 3 (LPH 3) Horizontal closed tubular type 3CO-H030 Menerima air dari Low Pressure Feedwater Heater 2 dan memanaskannya dari 97.1 C menjadi 119.4 C dengan uap pemanas.

Internal Plate menggunakan SUS304 (Stainless Steel) untuk ketahanan terhadap erosi/korosi internal. Kegagalan lapisan pelindung untuk menahan abrasi, sehingga pressure boundary terekspos langsung terhadap aliran erosif; Internal Components (Liner). Terutama pelat pelapis setebal 15mm yang dipasang di bagian dalam shell pada area tumbukan aliran Liner erosion Desain separator adalah tipe "Cyclone type" , di mana uap masuk dengan laju 19,000 kg/hr dan diputar. Gaya sentrifugal melempar butiran air keras ke dinding yang dilapisi liner; Partikel karat atau kotoran yang terbawa uap bertindak sebagai abrasive yang menggerus permukaan liner saat berputar; Jika ada ketidakrataan pada lasan liner, eddy current dapat mempercepat pengikisan di titik tertentu (localized erosion); Jika liner habis terkikis, aliran uap/air akan langsung menghantam dinding Shell (SB410) setebal 16mm. Karena SB410 lunak, dinding bejana akan menipis dengan cepat dan berisiko pecah; Erosi yang parah dapat memakan lasan pengikat liner, menyebabkan pelat liner lepas dan jatuh, berpotensi menyumbat nozzle drain; Serpihan logam liner yang terkikis akan terbawa aliran drain dan merusak valve di hilir Kerusakan ini tersembunyi di dalam bejana. Tidak ada indikasi luar sampai dinding utama mulai bocor atau liner lepas; Jika sebagian liner lepas dan bergetar terkena aliran uap, mungkin terdengar suara bising dari luar; Saat pengukuran ketebalan rutin dari luar, mungkin ditesurfacen area yang nilainya fluktuatif jika UT mampu menembus cladding dan membedakan layer Wajib membuka Inspection Opening S-5 saat shutdown.

Kegagalan sistem pengikat untuk menjaga bejana tetap diam pada posisinya saat menerima beban getaran atau gaya eksternal; Foundation Bolts / Anchor Bolts Ukuran M20, Jumlah: 4 titik pada Support Ring/Legs); Foundation bolt loosening Getaran operasional dari aliran uap turbulen tipe siklon dan getaran pipa yang merambat ke support, menyebabkan mur berputar mundur (back-off) secara perlahan; Siklus pemanasan bejana ke temperatur 350 degC menyebabkan flens kaki penyangga memuai. Jika baut tidak memiliki fleksibilitas elastis yang cukup, pendinginan unit dapat menyebabkan baut mengalami loss of tension; permukaan cat tebal di bawah kepala baut atau pada dudukan baja yang "turun/gepeng" seiring waktu, menciptakan celah mikro yang melonggarkan tegangan baut; Jika bejana goyang, beban berat bejana terutama saat berisi air/banjir ~2800 kg akan beralih ditahan oleh pipa nozzle (S-1/S-2). Ini menyebabkan tegangan berlebih dan retak pada lasan nozzle; Baut yang kendor akan menerima impact berulang setiap kali bejana bergetar, yang akhirnya mematahkan baut tersebut; Posisi bejana bergeser, menyebabkan ketidaklurusan pada sambungan pipa inlet/outlet; Terlihat celah antara washer (ring) dengan permukaan pelat penyangga; Washer di bawah mur dapat diputar dengan jari tangan; Adanya lelehan karat segar di sekitar kepala baut/mur, yang menandakan adanya gerakan mikro (fretting corrosion); Ketuk kepala baut/mur dengan palu inspeksi. Baut yang kencang berbunyi nyaring, baut kendor berbunyi tumpul; Gunakan kunci torsi untuk memverifikasi apakah mur bergerak sebelum mencapai nilai torsi standar Menggunakan 4 buah baut M20 yang cukup besar untuk menahan beban lateral; Inspeksi visual 5 tahunan; Biasanya dilengkapi dengan spring washer atau plat pengunci Setelah pengencangan, beri paint mark yang melintasi mur dan baut. Ini memudahkan inspeksi visual harian untuk melihat apakah mur berputar/bergeser; Gunakan sistem double nut pada baut fondasi M20 untuk mengunci posisi secara mekanis agar tahan getaran; Lakukan pengecekan retorquing 24 jam setelah unit beroperasi panas pertama kali setelah shutdown, untuk mengkompensasi relaksasi akibat pemuaian termal awal; +Turbine Steam Drain Separator Steam Drain Separator 3AS-T010 Struktur pendukung mekanis luar bejana tekan. Struktur bejana harus menahan beban referensi pada kondisi flooded 2800 kg.

Gaya horizontal yang timbul akan membengkokkan lug ke arah dalam; Mencoba mengangkat bejana dalam kondisi Flooded (Berat ~2800 kg ) padahal desain lug mungkin hanya untuk Empty Weight; Benturan keras pada lug saat transportasi atau pemasangan sebelumnya yang menyebabkan bengkok namun tidak diperbaiki; Penipisan pelat lug akibat korosi atmosferik karena posisinya di atas dan jarang dicat ulang, mengurangi luas penampang penahan beban; Risiko paling fatal. Jika deformasi berlanjut menjadi keretakan saat beban menggantung, lug bisa putus total dan bejana jatuh; Lubang yang melar atau pelat yang bengkok menyebabkan pin shackle tidak bisa masuk, sehingga proses maintenance/lifting tertunda; Deformasi ekstrem pada lug dapat merobek pelat head/shell tempat ia dilas (base metal tearing), merusak integritas tekanan bejana; Pelat lug terlihat tidak tegak lurus atau miring; Cat di pangkal lasan lug terlihat retak-retak sebagai tanda adanya yield stress / regangan pada logam; Lubang tempat masuknya shackle tidak lagi bulat sempurna, melainkan lonjong Lihat dari samping untuk memastikan kelurusan lug. Gunakan siku-siku jika perlu; Lakukan uji MT pada area lasan kaki lug untuk memastikan deformasi tidak memicu retakan pada sambungan ke shell; Coba masukkan pin shackle ukuran standar. Jika seret atau macet, berarti lubang sudah deformasi; Standar lifting lug biasanya didesain dengan Safety Factor 4:1 atau 5:1 terhadap beban putus; Prosedur K3 (Safety) mewajibkan inspeksi visual pada alat angkat sebelum digunakan; Biasanya terdapat pelat penguat di bawah lug untuk menyebar beban ke shell Wajibkan penggunaan spreader bar saat mengangkat bejana ini untuk memastikan gaya tarik tegak lurus vertikal (90 derajat) dan mencegah beban samping; Pastikan bejana sudah didrainase total sebelum diangkat. Jangan mengangkat bejana yang berisi air/kondensat; Jika ditesurfacen deformasi yang terlihat mata, dilarang melakukan perbaikan dengan memanaskan/mengetok lurus.

Sensing Element / Transducer (RTD Sensor, Vibration Pick-up/Probe, Local Gauge) Abnormal instrument reading Instrument failure-general Jika mode kegagalan adalah Fail Passive, motor beroperasi tanpa proteksi. Jika motor overheat sungguhan, sistem tidak akan tahu, berisiko winding burnout; Jika mode kegagalan adalah Fail Active (langsung menunjukkan nilai maks), unit akan Trip seketika; Hilangnya data tren untuk Predictive Maintenance Nilai pembacaan di DCS menunjukkan 'Over Range' (>150 C atau >20mm/s) atau 'Under Range' (-200 C) secara permanen; Tampilan status 'Bad Quality' atau warna indikator berubah; Jarum pada local gauge patah atau stuck; Lepas kabel sensor di Junction Box; Ukur resistansi RTD dengan Multimeter. Jika nilainya Infinite (∞) atau 0 Ohm, maka sensor rusak (Putus/Short internal); Untuk Vibration Probe, cek tegangan bias (Gap Voltage) apakah sesuai spesifikasi (-8V s/d -12V DC biasanya); Modul input DCS mendeteksi jika sirkuit terbuka dan otomatis men-set nilai ke Fail Safe untuk mencegah trip sembarangan atau memberi alarm; Dual Element Redundancy karena sebagian besar motor besar (CWP/CEP) memiliki 2 buah RTD per fasa (1 Main, 1 Spare) yang tertanam di stator; Adanya pengukur lokal fisik sebagai pembanding sensor elektronik; Jika RTD Winding rusak, pindahkan koneksi kabel ke elemen Spare RTD.

Toleransi tegangan: ±10% dari nominal. Motor gagal memutar pompa sama sekali atau terkunci (jammed), gagal mengatasi beban inersia awal meski mendapat suplai tegangan dalam batas ±10%. Rotating Elements (Motor shaft, Coupling disc pack/bolts, Bearing cage) Breakdown Breakage Ketika poros patah maka motor berputar tanpa beban (load loss) dan pompa diam; Jika bearing pecah maka rotor jatuh bergesekan dengan stator (Rotor Rubbing), merusak lilitan & inti besi permanen; Kehilangan aliran fluida seketika (Loss of Flow). Pada CWP/CEP, ini menyebabkan Vakum Drop -> Turbine Trip; Pecahan kopling bisa terlempar jika coupling guard tidak kuat (Projectile hazard); Suara ledakan/dentuman keras (Loud Bang/Grinding noise); Vibrasi melonjak ke nilai maksimum (Over range) seketika; Arus motor bisa drop drastis jika kopling putus atau melonjak tinggi jika poros macet/locked rotor Matikan unit & LOTO; Buka Coupling Guard; Lakukan Hand Barring (putar poros manual).

Resistansi isolasi (IR) CWP minimal 7 MΩ (motor 6kV), Make up pump minimal 100 MΩ. Hilangnya kemampuan isolator untuk menahan tegangan akibat lembap (IR turun di bawah 7 MΩ atau 100 MΩ), menyebabkan arus bocor ke bodi/tanah. Stator Winding & Insulation System Breakdown Earth/isolation fault Terjadi loncatan bunga api listrik (arcing) dari tembaga ke inti besi (core). Ini melelehkan laminasi besi stator dan merusak lilitan secara permanen (Motor gosong); Relay proteksi mendeteksi arus bocor ke tanah dan memutus Circuit Breaker seketika.

So a client +*can't see* a feature they weren't sold, even by guessing/typing the URL. +They just aren't prevented from finding it in the repo's source if they +have repo access at all — that's the part that would need the bigger job +below. + +If you need the frontend repo itself to not contain another client's page +source at all (not just block them from seeing it rendered), that's a +bigger job: `router/index.tsx`'s route tree would need to be filtered per +export the way `config/urls.py` is on the backend, and every page under +an unlicensed feature would need to come out of `src/pages/` and +`src/features/` too.

Until that refactor happens, every +client export currently ships the same PLN/TJB branding and plant-specific +copy (see also `src/pages/unit-3`, and `SchematicName`-style hardcoding on +the backend) regardless of who it's actually for. + +## `overlay/` — one per client, permanent, hand-maintained + +For whatever's unique to one client and genuinely not shared with any +other. Created with: + +```bash +scripts/new_client_overlay.sh +``` + +This is an **orphan branch** — no shared history with `main`, no shared +history with any other client's overlay. Nobody working on +`overlay/client-b` ever has a reason to check out `overlay/client-a`; the +two are as separate as if they were different repos. + +An overlay may only ever *add* files, never edit one that also exists on +`main`. Three extension points exist, all the same shape — a path that +doesn't exist on `main`, discovered via `import.meta.glob`, which +resolves to an empty object when nothing matches, so each is always safe +to be absent: + +- **Routes** — `src/router/overlay/.tsx`, picked up by + `src/router/index.tsx` via `import.meta.glob("./overlay/*.tsx")`. + Export `routes: RouteObject[]`. `scripts/new_client_overlay.sh` scaffolds + this one with an empty array — safe by construction, since an empty + array adds nothing until you fill it in. +- **Layout/shell** — `src/shared/components/layouts/overlay/AppLayout.tsx`, + picked up by `src/shared/components/layouts/AppLayout.tsx` (every + domain's `*LayoutRoute` imports `AppLayout` from there, never + `DefaultAppLayout` directly, so this one file swaps the whole shell — + sidebar, navbar, colors — everywhere at once). Default export, same + props as `DefaultAppLayout`. +- **Theme** — `src/styles/overlay/*.css`, loaded by `src/main.tsx` after + `index.css`, so redefining `:root`/`.dark`'s CSS custom properties + (`--primary`, `--background`, etc.) there wins the cascade. + +The layout and theme hooks are **not** scaffolded with a placeholder file +the way routes are, and that's deliberate: an empty `routes` array has no +effect, but the layout/theme hooks activate the instant a matching file +exists at all, regardless of content. Only add one once you have a real +replacement. + +Also allowed, same "new path only" rule: +- New components/pages that an overlay route or layout references. +- New static assets under a path `main` doesn't already use (see the + branding gap above for why an *existing* asset path isn't safe to + override yet). + +That constraint isn't arbitrary: `client/` is regenerated from +scratch on every export, so `.env.example` and every existing file are +rewritten every single time. An overlay branch has no commit in common +with whatever `client/` looks like *this* time, so if it touched a +file the export also touches, every future export would hit the same +merge conflict forever. Sticking to new, untouched paths sidesteps that +entirely — a merge that only adds files can't conflict with content it +never shared. + +`export_client.sh` merges `overlay/` into the freshly-built +`client/` automatically, if that branch exists, right before the +final guard — so overlay content gets the same leak check as everything +else. diff --git a/fe-digitaltwin-v2/Jenkinsfile b/fe-digitaltwin-v2/Jenkinsfile new file mode 100644 index 0000000..7cb4cc5 --- /dev/null +++ b/fe-digitaltwin-v2/Jenkinsfile @@ -0,0 +1,135 @@ +pipeline { + agent any + + environment { + DOCKER_HUB_USERNAME = 'aimodocker' + DOCKER_AUTH = credentials('aimodocker') // provides DOCKER_AUTH_USR / DOCKER_AUTH_PSW + IMAGE_NAME = 'digitaltwin_frontend_v2' + + // Populated in Checkout stage + GIT_COMMIT_HASH = "" + IMAGE_TAG = "" + SECONDARY_TAG = "" + } + + parameters { + string( + name: 'EXTRA_DOCKER_BUILD_ARGS', + defaultValue: '', + description: 'Optional extra docker build args, e.g. --build-arg VITE_AUTH_APP_URL=https://api.example.com/auth' + ) + } + + stages { + + stage('Checkout & Setup') { + steps { + script { + checkout scm + + GIT_COMMIT_HASH = sh(script: 'git rev-parse --short HEAD', returnStdout: true).trim() + + def branch = env.BRANCH_NAME ?: 'unknown' + echo "Branch: ${branch} | Commit: ${GIT_COMMIT_HASH}" + + if (branch == 'main') { + IMAGE_TAG = GIT_COMMIT_HASH + SECONDARY_TAG = 'latest' + } else { + IMAGE_TAG = "temp-${GIT_COMMIT_HASH}" + SECONDARY_TAG = "" + } + + echo "Primary Tag : ${IMAGE_TAG}" + echo "Secondary Tag: ${SECONDARY_TAG ?: '(none)'}" + } + } + } + + stage('Docker Login') { + steps { + sh 'echo "$DOCKER_AUTH_PSW" | docker login -u "$DOCKER_AUTH_USR" --password-stdin' + } + } + + stage('Build & Tag') { + steps { + script { + def fullImage = "${DOCKER_HUB_USERNAME}/${IMAGE_NAME}" + def viteArgs = [ + 'VITE_AUTH_APP_URL', + 'VITE_EFFICIENCY_APP_URL', + 'VITE_OH_APP_URL', + 'VITE_PFI_APP_URL', + 'VITE_API_V1_LIVE', + 'VITE_LCCA_APP_URL', + 'VITE_RELIABILITY_APP_URL', + 'VITE_RISK_MATRIX_APP_URL', + 'VITE_EQUIPMENT_IMAGE_URL', + 'VITE_API_MONITORING_URL', + 'VITE_RBD_APP_URL', + 'VITE_IRCFA_APP_URL', + 'VITE_AHM_APP_URL', + 'VITE_OPS_DOCK_APP_URL', + 'VITE_AUTH_URL', + 'VITE_AUTH_SECRET', + 'VITE_ENABLE_SECURE_EXPORT', + 'VITE_ALLOW_ACCESS_EFFICIENCY', + 'VITE_ALLOW_ACCESS_PFI', + 'VITE_ALLOW_ACCESS_RELIABILITY', + 'VITE_ALLOW_ACCESS_RISK_MATRIX', + 'VITE_ALLOW_ACCESS_LCCA', + 'VITE_ALLOW_ACCESS_RBD', + 'VITE_ALLOW_ACCESS_OH', + 'VITE_ALLOW_ACCESS_IRCFA', + 'VITE_ALLOW_ACCESS_AHM', + 'VITE_ENVIRONMENT' + ].collect { "--build-arg ${it}" }.join(' ') + def extraArgs = params.EXTRA_DOCKER_BUILD_ARGS?.trim() ?: '' + + sh "docker build ${viteArgs} ${extraArgs} -t ${fullImage}:${IMAGE_TAG} ." + + if (SECONDARY_TAG) { + sh "docker tag ${fullImage}:${IMAGE_TAG} ${fullImage}:${SECONDARY_TAG}" + } + } + } + } + + stage('Push to Docker Hub') { + steps { + script { + def fullImage = "${DOCKER_HUB_USERNAME}/${IMAGE_NAME}" + + sh "docker push ${fullImage}:${IMAGE_TAG}" + + if (SECONDARY_TAG) { + sh "docker push ${fullImage}:${SECONDARY_TAG}" + } + } + } + } + } + + post { + always { + script { + sh 'docker logout' + + def fullImage = "${DOCKER_HUB_USERNAME}/${IMAGE_NAME}" + if (IMAGE_TAG?.trim()) { + sh "docker rmi ${fullImage}:${IMAGE_TAG} || true" + } + if (SECONDARY_TAG?.trim()) { + sh "docker rmi ${fullImage}:${SECONDARY_TAG} || true" + } + } + } + success { + echo "Image ${DOCKER_HUB_USERNAME}/${IMAGE_NAME}:${IMAGE_TAG} pushed successfully." + } + failure { + echo "Pipeline failed on branch ${env.BRANCH_NAME}." + } + } +} diff --git a/fe-digitaltwin-v2/README.md b/fe-digitaltwin-v2/README.md new file mode 100644 index 0000000..6ea3959 --- /dev/null +++ b/fe-digitaltwin-v2/README.md @@ -0,0 +1,192 @@ +# DigitalTwin Frontend Developer Guide (fe-digitaltwin-v2) + +> [!IMPORTANT] +> **Start here before creating or handing off frontend work** +> +> - 🎨 **Design-system guideline:** Open the public +> [`/design-system`](http://localhost:3002/design-system) page to inspect the +> project’s tokens, typography, reusable shadcn-style components, MapCN +> examples, and AI development workbench.

This guide provides a clear and simple overview of our framework stack, development workflows, production build processes, and key benefits. + +--- + +## 🚀 The Framework Stack + +This project is built using a modern frontend stack designed for speed, type safety, and rich user interfaces: +* **Core Framework**: **React 18** (with TypeScript for full type safety). +* **Build Tool & Dev Server**: **Vite 6** (provides instantaneous hot module replacement and lightning-fast builds). +* **Styling**: **Tailwind CSS** combined with UI libraries like **HeroUI** and **Mantine** for rich, premium interfaces. +* **State Management**: **Zustand** (global state), **Jotai** (atomic state), and **React Query** (server cache / data fetching). +* **Routing**: **React Router Dom v7**. + +--- + +## 🛠️ Development Flow & Process + +### 1. Prerequisites +Ensure you have **Node.js** (v18+ recommended) and **npm** installed on your machine. + +### 2. Install Dependencies +Run this command from the root of the project to install all required libraries: +```bash +npm install +``` + +### 3. Local Development Server +Start the local development server by running: +```bash +npm run dev +``` +* **Vite Advantage**: This boots up almost instantly because it leverages native ES modules instead of pre-bundling the entire codebase. +* **Hot Module Replacement (HMR)**: Changes you make in code are instantly reflected in the browser without losing application state. +* **Vite Proxy**: Any API requests made to `/api-proxy` are automatically forwarded to the backend service (configured at `http://192.168.1.82:8000`) to avoid CORS issues during development. + +### 4. Code Conventions & Path Aliases +To avoid messy relative imports (e.g. `../../../../components`), we use configured path aliases in `vite.config.ts` and `tsconfig.json`: +* `@/components` ➔ maps to `src/shared/components` +* `@/lib/api-url` ➔ maps to `src/shared/api-url` +* `@/lib/fetcher` ➔ maps to `src/shared/fetcher` +* `@/lib/APIs/types` ➔ maps to `src/shared/types` +* `@` ➔ maps to `src` + +--- + +## 📦 Production Build Flow + +Before deploying to production, the codebase must be compiled, type-checked, and bundled into optimized static assets. + +### 1. Build for Production +Run the build script: +```bash +npm run build +``` + +Under the hood, this command executes: +```bash +tsc -b && vite build +``` +1. **`tsc -b`**: Runs the TypeScript compiler in build mode to verify type correctness across the entire application. If there are any type mismatches, the build will fail, preventing runtime errors. +2. **`vite build`**: Bundles, minifies, and optimizes your JavaScript, CSS, and asset files. Vite uses **Rollup** under the hood to perform tree-shaking (removing unused code) and code-splitting (splitting assets into smaller chunks for faster page loading). + +### 2. Preview the Production Build Locally +To test the output of the production build locally before actual deployment, run: +```bash +npm run preview +``` +This starts a local static file server hosting the contents of the built `dist` folder. + +### 3. Docker Deployment + +The production image (`Dockerfile`) builds the Vite bundle, then serves it +through **nginx**, which also reverse-proxies every backend API prefix +(`/auth`, `/efficiency`, `/pfi`, `/lcca`, `/reliability`, `/risk-matrix`, +`/monitoring`, `/rbd`, `/ahm`, `/ops-dock`, `/optimumoh`, `/ircfa`, `/api`) +to the real backend server-side (see `nginx.conf`). + +This matters for tunneling: all `VITE_*_APP_URL` values are baked in as +**relative paths** by default, so the browser only ever calls the app's own +origin. When you tunnel this container's port (ngrok, cloudflared, etc.), +the browser never tries to reach the backend's local IP directly — nginx +inside the container forwards those calls to the backend for you. + +```bash +docker compose up -d --build +``` + +The app is then available at `http://localhost:8081` (configurable via +`FRONTEND_PORT`) — tunnel **this** port, not the backend's. + +By default nginx forwards API calls to `http://192.168.1.82:8000` (and +`http://192.168.1.119:8000` for IRCFA, which runs on a separate host). To +point at a different backend without rebuilding the image, copy +`.env.docker.example` to `.env.docker`, adjust `BACKEND_URL` / +`BACKEND_URL_IRCFA` / `FRONTEND_PORT`, and run: + +```bash +docker compose --env-file .env.docker up -d --build +``` + +> **SSO caveat:** if you need SSO login to work for outside users, set the +> `VITE_AUTH_URL` build arg (in `docker-compose.yml`) to the actual public +> tunnel URL and rebuild — it's baked in as the OAuth `redirect_uri` sent to +> the identity provider, and PLN's IAM must have that exact URL +> allow-listed, or the login redirect will go nowhere. + +--- + +## 📋 Summary of Key Commands + +| Command | Purpose | When to Use | +| :--- | :--- | :--- | +| `npm install` | Installs all project dependencies | When setting up the project or after dependencies change | +| `npm run dev` | Starts the local interactive Vite development server | During active coding and daily feature development | +| `npm run build` | Compiles TypeScript and builds optimized production files | Before deploying code to production | +| `npm run preview` | Serves the production-built code locally for testing | To verify that the production bundle works correctly | +| `npm run lint` | Runs ESLint to check for code quality and styling errors | Before committing code or during CI/CD checks | + +--- + +## 💎 Why Vite & This Stack? (Key Benefits) + +1. **Instant Startup**: Unlike traditional bundlers (like Webpack) which bundle the entire app before serving, Vite only processes the code requested by the browser on demand. +2. **Unmatched HMR Speed**: Hot Module Replacement speed remains lightning fast regardless of the size of the application. +3. **Type Safety**: TypeScript prevents standard runtime bugs during compilation. +4. **Optimized Assets**: CSS and JS are split, minified, and bundled to ensure the end-user downloads only what they need, resulting in high performance and fast load times. + +--- + +## ⚡ Why Vite + React is More Efficient Than Next.js (For This Project) + +> **Source**: This section is based on the official internal Frontend Refactor PRD — *"Frontend Refactor: Next.js → Vite + React, Migration PRD & Implementation Guide, Version 1.0"* (`ref/frontend_refactor_prd.pdf`). + +The previous frontend was built on **Next.js (App Router)**. After analysis, it was decided to migrate to **Vite + React**. The core reason: **this application uses zero Server-Side Rendering (SSR) or Static Site Generation (SSG)** — meaning every single page was already marked `'use client'`. Next.js was adding complexity with zero benefit. + +### Side-by-Side Comparison + +| Concern | Next.js (Before) | Vite + React (Now) | +| :--- | :--- | :--- | +| **Rendering** | All pages were `'use client'` — SSR was unused overhead | Pure Client-Side Rendering by design, no wasted config | +| **Routing** | App Router conventions + layouts overhead | React Router v7 — explicit, simple, easy to read | +| **Auth** | NextAuth tightly coupled to Next.js internals | Custom `useAuth` hook, full control in ~80 lines | +| **Data Fetching** | SWR + manual token threading | React Query with centralized, clean config | +| **Bundle Config** | Next.js opinionated build pipeline | Vite — fast, transparent, fully flexible | +| **Mental Model** | Server/client boundary confusion | Pure React — no framework magic, simpler onboarding | + +### What Was Eliminated + +* ❌ All `'use client'` directive boilerplate — **not needed in Vite**. +* ❌ **NextAuth / Auth.js** — replaced by a lightweight custom `AuthProvider + useAuth` hook. +* ❌ **SWR** — replaced by **React Query** (TanStack Query v5) with a single centralized config. +* ❌ **Next.js file-based routing** — replaced by an explicit, readable `router/index.tsx` using React Router v7. +* ❌ **`NEXT_PUBLIC_` env variable prefix** — replaced by the simpler `VITE_` prefix via `import.meta.env`. + +### What Was Gained + +* ✅ **Faster HMR**: Vite's dev server starts almost instantly and stays fast at any project scale. +* ✅ **Simpler Mental Model**: No server/client boundary confusion. Everything is pure React. +* ✅ **Full Auth Control**: The custom `AuthProvider` replicates everything NextAuth did in ~80 lines, with no external dependency lock-in. +* ✅ **Better DX (Developer Experience)**: Easier onboarding for new developers — no Next.js-specific conventions to learn. +* ✅ **Transparent Build Pipeline**: `vite build` is predictable and fully configurable, unlike Next.js's opinionated pipeline. +* ✅ **Feature-Based Architecture**: A clean `features/` folder structure (one folder per domain) replaces the mixed `app/` directory convention. + +### Migration Goals (from PRD) + +The refactor was driven by these official goals: +1. Eliminate Next.js overhead (App Router, server/client split, SSR config). +2. Adopt a clean, feature-based folder structure from scratch. +3. Replace Auth.js (NextAuth) with a lightweight custom JWT auth layer. +4. Replace SWR with React Query (TanStack Query) for data fetching. +5. Maintain full feature parity — no regressions. +6. **Improve DX**: faster HMR, simpler mental model, easier team onboarding. diff --git a/fe-digitaltwin-v2/components.json b/fe-digitaltwin-v2/components.json new file mode 100644 index 0000000..e15e244 --- /dev/null +++ b/fe-digitaltwin-v2/components.json @@ -0,0 +1,24 @@ +{ + "$schema": "https://ui.shadcn.com/schema.json", + "style": "new-york", + "rsc": false, + "tsx": true, + "tailwind": { + "config": "tailwind.config.ts", + "css": "src/index.css", + "baseColor": "slate", + "cssVariables": true, + "prefix": "" + }, + "iconLibrary": "lucide", + "aliases": { + "components": "@/components", + "utils": "@/lib/utils", + "ui": "@/components/ui", + "lib": "@/lib", + "hooks": "@/hooks" + }, + "registries": { + "@mapcn": "https://mapcn.dev/r/{name}.json" + } +} diff --git a/fe-digitaltwin-v2/docker-compose.yml b/fe-digitaltwin-v2/docker-compose.yml new file mode 100644 index 0000000..5cce917 --- /dev/null +++ b/fe-digitaltwin-v2/docker-compose.yml @@ -0,0 +1,40 @@ +services: + frontend: + build: + context: . + dockerfile: Dockerfile + # All VITE_*_APP_URL build args default to relative paths (see + # Dockerfile) so the browser only ever calls this same origin; nginx + # proxies each prefix to BACKEND_URL server-side.
