Abstract:
1. A platform mounted onto an anchor handling vessel above a water line of the vessel for receiving a mooring line retrieved from the seabed, the platform comprising: a. a first end having a chain chute for supporting a chain portion of the mooring line; b. a second end movable relative to the first end for adjusting tension in the mooring line, the platform further comprising a wire rope chute and having rollers mounted on the wire rope chute adapted to contact and protect a mooring line segment passing over the wire rope chute; c. a positional control mechanism comprising a first hydraulic mechanism for adjusting longitudinal distance between the first end and the second end; d. a chain stopper movable between a chain locking position protruding above an upper surface of the chain chute and a released chain position receded below the upper surface of the chain chute; e. a chain stopper control mechanism comprising a second hydraulic mechanism for controlling the position of the chain stopper relative to the chain chute to lock and unlock movement of the chain portion of the mooring line segment relative to the platform; f. a wire socket stopper movable between a wire rope locking position and a released wire rope position; g. a wire socket stopper control mechanism comprising a third hydraulic mechanism for controlling the position of the wire socket stopper relative to the wire rope chute to lock and unlock movement of a wire portion of the mooring line segment relative to the platform; and h. a curved deflector plate mounted adjacent the platform and adapted to guide the mooring line between the wire rope chute of the platform and a reel located on the anchor handling vessel.
