Life Raft Annual Servicing refers to the mandatory inspection, testing, and maintenance of a ship’s life rafts to ensure they are in perfect working condition in case of an emergency. This servicing is required under SOLAS (Safety of Life at Sea) regulations and must be performed at approved service stations by certified professionals.

Why is Motor & Alternator Rewinding Important?

•  Restores Performance – Revitalizes worn-out coils and insulation to enhance motor efficiency.
•  Cost-Effective – Rewinding is more affordable than replacing the entire motor or alternator.
•  Prevents Downtime – Ensures continuous operation, avoiding costly delays in ship functions.
•  Reduces Energy Consumption – A properly rewound motor operates more efficiently, consuming less power.
•  Ensures Compliance – Meets maritime electrical safety standards and classification society regulations.

Signs That a Motor or Alternator Needs Rewinding

•  Overheating – Excessive heat buildup due to faulty windings.
•  Reduced Efficiency – Increased power consumption with decreased performance.
•  Burnt Smell or Smoke – Indicates damaged insulation in the windings.
•  Frequent Tripping of Circuit Breakers – Caused by short circuits or winding failures.
•  Unusual Noise or Vibration – Misalignment or loose windings affecting smooth operation.
•  Intermittent Power Supply – Alternator failing to generate consistent electrical output.

Step-by-Step Process of Motor & Alternator Rewinding

Inspection & Diagnosis

•  Visual and thermal imaging inspection to identify faults in the windings.
•  Electrical testing to detect short circuits, open circuits, or insulation breakdown.
•  Checking rotor, stator, bearings, and insulation resistance.

Stripping & Cleaning the Winding

•  Carefully removing old coils without damaging the stator core.
•  Cleaning the motor or alternator components from dirt, oil, and corrosion.
•   Drying and preparing the surface for new winding.

Rewinding & Coil Installation

•  Custom-wound copper or aluminum coils installed as per original specifications.
•  Applying high-quality insulation materials to prevent breakdown.
•  Precision winding using automated machines or skilled hand winding.

Varnishing & Curing

•  Coils are dipped in epoxy varnish for insulation and heat resistance.
•  Oven baking or air drying to enhance durability.

Reassembly & Testing

•   Reassembling components, aligning shafts, and securing windings.
•   Running diagnostic tests, including load testing and high-voltage testing.
•   Ensuring correct rotation, voltage output, and frequency stability.

Where is Rewinding Done?

•  Onboard Repairs – Emergency rewinding services while docked or at sea.
•  Shipyards & Dry Dock Facilities – Complete motor & alternator rewinding during maintenance.
•  Marine Electrical Workshops – Specialized facilities offering full rewinding services.

Why Choose Expert Rewinding Services?
