Ground tackle includes equipment such as mooring winches, windlasses, and anchors.

On large ships, this tightening can be accomplished with the help of heavy machinery called mooring winches or capstans.

Hence, the cables were gradually tightened by a steam mooring winch aboard ship and the ship held in place.

Mooring winches and lifting equipment.

Large ships generally tighten their mooring lines using heavy machinery called mooring winches or capstans.

The equipment load includes cranes (for stores handling and abeam replenishment), steering and rudder gear, thyristor-controlled winch/windlasses and double drum mooring winches.

The water depth in Robson Bight, up to 400 meters, presented a real challenge and required the use of four mooring winches with a total of 6 km of mooring lines.

Meanwhile, he and another crewman led the messenger line inboard of the bitts holding the ‘firewire’, round a standing roller bollard and between another set of bitts, to the mooring winch.
