The pulling forces of the stern anchor drum winch will be as per the requirements for this anchor weight. The regulations prescribe steel wire length of 110 meters, which we have taken into account as well. Mooring lines shall be of uniform thickness throughout their length, as below mentioned table is stating. Further requirements for preparing mooring lines for passing through the St. Lawrence Seaway before entering a lock: unless the winches can pay out at a minimum speed of 46 meter per minute, sufficient length of mooring lines to reach out the mooring posts on the lock wall shall be drawn off the winch drums and laid out on the deck and the eye of each mooring line shall be passed outward through the fairleads at the side SEC builds the anchor drum winches in a range with a nominal load up to 3000 kN.
