Rewinding & Overhaul Alternator – MV. ANDHIKA ATHALIA

Pekerjaan rewinding dan overhaul alternator ini dilaksanakan pada kapal MV. ANDHIKA ATHALIA sebagai bagian dari program pemeliharaan untuk mengembalikan performa dan keandalan sistem pembangkit listrik kapal. Alternator dengan kapasitas 500 kVA, tegangan 440 Volt, dan frekuensi 60 Hz menjalani proses inspeksi menyeluruh guna memastikan seluruh komponen bekerja sesuai standar operasional.

Proses pekerjaan meliputi pembongkaran unit alternator, pemeriksaan kondisi stator dan rotor, pelaksanaan rewinding pada kumparan yang mengalami penurunan kualitas isolasi, penggantian komponen yang diperlukan, pembersihan, perakitan kembali, serta pengujian untuk memastikan performa kelistrikan dan mekanis kembali optimal.

Scope of Work

• Overhaul alternator 500 kVA, 440 V, 60 Hz
• Pembongkaran dan inspeksi komponen stator serta rotor
• Rewinding kumparan alternator
• Pembersihan, penggantian komponen, dan perakitan kembali
• Pengujian insulation resistance dan electrical continuity
• Running test dan verifikasi performa alternator

Seluruh pekerjaan dilakukan sesuai prosedur pemeliharaan peralatan listrik dengan memperhatikan standar kualitas dan keselamatan kerja. Setiap tahapan inspeksi, rewinding, hingga proses perakitan dilakukan secara teliti untuk memastikan kondisi alternator kembali memenuhi spesifikasi operasional.

Setelah proses overhaul selesai, alternator menjalani serangkaian pengujian untuk memverifikasi nilai isolasi, fungsi kelistrikan, serta kestabilan operasi sebelum dinyatakan siap kembali digunakan sebagai sistem pembangkit listrik kapal.

Melalui proses rewinding dan overhaul yang presisi, kami memastikan alternator mampu kembali beroperasi secara andal, efisien, dan mendukung kontinuitas sistem kelistrikan kapal.

Alternator Rewinding & Overhaul – MV. ANDHIKA ATHALIA

This project involved the rewinding and overhaul of a 500 kVA, 440 V, 60 Hz alternator onboard MV. ANDHIKA ATHALIA as part of a preventive maintenance program to restore the reliability and performance of the vessel's electrical power generation system.

The work included complete alternator dismantling, inspection of the stator and rotor assemblies, rewinding of deteriorated stator windings, replacement of necessary components, cleaning, reassembly, and comprehensive electrical testing to ensure the alternator operates according to its original specifications.

SCOPE OF WORK

• Alternator overhaul (500 kVA, 440 V, 60 Hz)
• Complete dismantling and inspection of stator and rotor components
• Alternator winding rewinding
• Cleaning, component replacement, and reassembly
• Insulation resistance and electrical continuity testing
• Running test and performance verification

All maintenance activities were carried out in accordance with established electrical maintenance procedures and quality standards. Every stage of inspection, rewinding, and reassembly was performed carefully to restore the alternator to reliable operating condition.

Following the overhaul process, the alternator underwent a series of electrical and operational tests to verify insulation integrity, electrical performance, and operational stability before being returned to service.

Through precise rewinding and overhaul procedures, we ensure reliable alternator performance to support safe and continuous onboard power generation.
