  • Patent number: 4729332
    Abstract: A mooring apparatus comprises a mooring bridle 1, a bitting part 2 equipped to the mooring bridle at an end thereof, a mooring winch 3 connected to the mooring bridle at another end, a cable 4 suspending the bitting part, and a crane 5 connected to the suspending cable. When carrying out the mooring operation, the suspending cable 4 is coiled by driving the crane 5 with respect to a bitt or bollard on an opposite vessel or quay and subsequently the mooring bridle is given tension by working the winch 3, and the mooring operation is finished. The winch is located below the crane arm and is disposed to rotate simultaneously with the crane so that the winch always faces the same direction as the arm to prevent twisting of the bridle. When the vessel leaves, the above mentioned operation is performed reversely. Due to the mechanical operation of the above mentioned apparatus, automation, rationalization and safety of the mooring work may be accomplished.

The winch is located below the crane arm and is disposed to rotate simulataneously with the crane so that the winch always faces the same direction as the arm to prevent twisting of the bridle. When the vessel leaves, the above mentioned operation is performed reversely. Due to the mechanical operation of the above mentioned apparatus, automation, rationalization and safety of the mooring work may be accomplished.
