Motor Rewinding at Vung Tau Port – Performed by VietNam ShipRepair
When a container ship’s Main Engine Lubrication Oil (M.E L.O) pump motor fails, operations are severely impacted. At Vung Tau Port, the expert technicians from VietNam ShipRepair recently executed a complete Motor Rewinding of a damaged M.E L.O pump motor on a container vessel. This service ensures the continuous circulation of oil, maintaining engine performance and avoiding major failures.
In addition, we offer these services throughout Vietnam’s key ports and anchorages, including Da Nang, Nghi Son, Ho Chi Minh City, and more. Furthermore, our processes meet the strict international standards set by IMO and IACS, guaranteeing high-quality and safe marine repairs.

Why the M.E L.O Pump Motor Is Critical in Marine Operations
The Main Engine Lubrication Oil Pump operates using a high-efficiency electric motor, essential for distributing lubrication oil to engine components such as bearings, pistons, and the crankshaft. Consequently, when this motor breaks down, lubrication is interrupted, risking overheating and serious mechanical failure.
Therefore, scheduled inspections and timely rewinding of motors are critical for sustaining engine integrity. A well-maintained motor reduces the chance of sudden breakdowns and prolongs the vessel’s operating life.
Common Causes That Require Motor Rewinding
Marine motors endure demanding conditions that often lead to:
- Thermal degradation of insulation
- Moisture intrusion causing short circuits
- Overload or voltage imbalance
- Excessive vibration damage
As a result, motor rewinding becomes essential when insulation resistance declines or the motor stops functioning. Rewinding restores the motor to its original performance at a lower cost than full replacement.
Step-by-Step Motor Rewinding Process by VietNam ShipRepair
Our certified marine electricians follow a standardized, efficient rewinding workflow:
1. Preliminary Inspection and Diagnosis
Initially, the motor undergoes electrical and visual testing. We assess insulation resistance (IR), continuity, and phase imbalance.
2. Disassembly and Cleaning
After disassembly, we remove all windings. Then, we clean the stator and rotor thoroughly to eliminate dirt and carbon deposits.
3. Winding Replacement
Using OEM-grade copper wires, our team rewinds the stator according to the original specifications. In addition, new insulating materials are applied.
4. Resin Varnishing and Curing
Windings are coated with marine-grade resin and oven-cured under controlled conditions to increase longevity and resistance.
5. Assembly and Testing
Next, we reassemble the motor and test for insulation strength, high-voltage resistance, and balance to ensure full functionality.
6. Onboard Installation and Commissioning
Once the motor is returned to the vessel, our engineers install it, connect it to the M.E L.O pump, and conduct full operational trials.
