Electric Windlass Troubleshooting and Repair

Intro

The Windlass was operating at very low speeds only. At higher speeds, the system tripped and reported an overload fault.

An Alatas windlass specialist with Variable Frequency Drive experience was mobilized to troubleshoot on board, on top urgent basis.

BACKGROUND

Recently, the electric motor burned out. It was overhauled ashore in Vietnam and reinstalled by the crew.

Upon checking the system, our engineer concluded that the electric motor windings were not according to the correct specifications. This caused the motor to draw too much current, causing the system to stop as soon as a higher speed was selected.

ALATAS’ SOLUTION

A new motor or a correctly overhauled electric motor was required. There was stock available from previous owners in Singapore.

The Maritime Port Authority of Singapore (MPA) granted urgent port authorization and hot work permission to Alatas Service Department, who then dispatched our deck machinery repair crew, comprising tools, equipment, and an A-frame, and completed the Windlass motor replacement overnight.

The windlass then was tested and it was functioning normally again at all speeds.
