The electric drives of anchor-handling and mooring gear are used to heave in the anchor and perform mooring operations.
Accordingly, they are used in windlasses, anchor and anchor-mooring capstans, mooring capstans, automatic and non-automatic mooring winches. At present most of these machines are equipped with electric drives having special characteristics which suit the operating conditions of such machines.
According to the Register the power rating of an electric drive used in the anchor-handling gear must be such that the anchor chain is heaved in at a minimum speed of 0.17 m/s with the sprocket pull, in Newtons.
