ABSTRACT:
The present invention provides a vessel mounted mooring system and a method for its installation. The method involves the construction of a vertical well in the vessel extending from the deck to the bottom plates. A lower bearing ring which circumscribes the well is connected to the underside of the bottom plates and extends beyond the keel. A lower turret unit is supported substantially within the bearing ring. A middle turret unit is placed into the well and connected to the lower turret unit. An upper bearing ring which circumscribes the well is mounted to the deck. An upper turret unit is connected to the middle turret unit whereupon the assembly of the upper, middle and lower turret units is supported and guided by the upper bearing ring and further guided by the lower bearing ring. Chain lockers which include chains and windlasses are mounted to the upper turret unit for selectively paying out or reeling in chain through the upper, middle and lower turret unit to allow the chain to be connected near the subsea floor.
