Motor Overhaul for Cruise Ship
Rotec’s Electrical Mechanical Services division completed the overhaul of 18 ship’s motors last month for a leading leisure industry company.
The cruise ship, who carries thousands of passengers each year, voyages throughout the Baltic, Norwegian Fjords, and the Mediterranean. In regular use, our engineers had a strict time limit of 14 days to remove, overhaul and reinstate all 18 motors whilst the ship was in dry dock.
The scope of works included:
Removal and inspection
- Safe and efficient electrical and mechanical disconnection of all 18 motors, including the port and starboard anchor winch motors.
- Thorough inspection of all plate detail and insulation valves.
Overhaul
- Full steam cleaning of the motors and re-varnishing as required.
- Baking of the motors in a temperature-controlled oven to ensure proper curing of the varnish and to remove any residual moisture.
- New bearings fitted where required.
- Repair of worn end-shields by sleeving and machining back to tolerance.
- Replacement of brake pad discs with excessive wear.
- Insulation tests conducted at 500 volts to ensure electrical safety and integrity.
- Dynamic balancing carried out to avoid unnecessary vibrations, reduce noise, prevent mechanical failure, and improve balance and efficiency.
- Inspection of all electrical cables for damage.
Reinstallation
- Safe and efficient reinstallation of all 18 motors back onto the ship.
- Careful reconnection of all electrical and mechanical components.
Report
- A detailed report, with images of all motors, was completed and a copy sent to the client upon completion.
All work was completed within the 14 day schedule deadline.
The completed overhaul will significantly improve the reliability and lifespan of the ship’s motors, reducing the risk of unexpected breakdowns and ensuring continued safe and efficient operation.
