A mooring unit and method of retrofitting a mooring unit are provided. Certain existing combination mooring units, of the type having two wire rope drums and two wildcats, are experiencing increased winch drive train component stress levels during operation when used in water deeper than they were designed for. Existing units are modified by providing left and right twin drum traction winch assemblies and additional winches. The existing wire rope drums are discarded, or reused with the additional winches. The additional winches are preferably mounted below the mooring unit. The twin drum traction winch assemblies, which deliver a constant winch pull force, are vertically mounted within the support flanges where the removed wire rope drums were previously mounted, without any modification to the support flanges. |
