Marine Diesel Engine Overhaul and Precision Maintenance
In maritime operations, propulsion reliability dictates voyage safety and charter continuity. A marine diesel engine is the vital heart of a vessel, governing navigation schedules, fuel economics, and commercial productivity.
PT Pelican Mitra Sejati executes structured Marine Diesel Engine Maintenance and Overhaul programs engineered to preserve mechanical integrity under continuous maritime load cycles. Through systematic diagnostic assessments and precision engineering execution, we restore machinery performance to certified manufacturer standards.
Technical Coverage Across Engine Systems
- Comprehensive engine condition assessments and borescope cylinder inspections
- Top overhauls and complete major overhaul programs for main and auxiliary engines
- Fuel injection system servicing, nozzle testing, and injection pump timing calibration
- Turbocharger dismantling, ultrasonic cleaning, bearing renewal, and dynamic balancing
- Cooling water heat exchanger descaling and lube oil circuit servicing
- Post-overhaul dock trials, full load testing, and operational parameter verification
Every engineering intervention is conducted under documented procedures with rigorous measurement protocols. We do not merely replace worn components: we re-establish mechanical reliability.
Operational Value for Vessel Managers
Disciplined engine maintenance yields measurable operational benefits:
- Optimized specific fuel oil consumption (SFOC) through proper combustion balancing
- Mitigation of catastrophic mechanical breakdowns and off-hire losses
- Stable power output across fluctuating maritime sea states
- Extended service life of cylinder liners, pistons, and main bearings
- Assured regulatory compliance during classification society annual surveys
Field Execution Record
Our mechanical teams possess extensive practical experience executing complete Top Overhauls on high-tonnage marine diesels, including cylinder head refurbishment, valve guide renewal, valve seat grinding, and precision torquing. Test-bench calibration of high-pressure fuel injectors ensures balanced cylinder combustion prior to harbor sea trials.
