Abstract

A ship's mooring winch system automatically maintains tension in the mooring rope continuously, the winch motor being a polyphase AC induction motor energised by a converter which includes a rectifier and an inverter. The frequency of the inverter output is preferably the rated slip-frequency of the motor, and the converter controlled according to sensed motor speed and rectifier current. The motor maintains tension without exceeding its rated duty and automatically pays out or recovers rope at the rated torque, whilst stalled, without the use of rope tension sensors and avoiding the need to repeatedly operate the winch brakes.
