Abstract
A system for mooring a floating storage vessel (10) in the open sea for remaining on station at all times without any disconnection of the vessel (10) from the mooring system. The mooring system includes a plurality of anchor legs (26) connected to a turret (20) in the well (18) of the vessel (10) with at least one submerged support buoy (28) for each anchor leg (26). The submerged support buoy (28), by supporting a substantial portion of the weight of the associated anchor leg (26), reduces the vertical loads on the turret bearings (46, 48) and permits the turret (20) to be easily rotated from the torque exerted by the anchor legs (26) without any separate turret drive means. The system includes in FIG. 5 an embodiment in which a plurality of support buoys (28A) are provided for each anchor leg (26A). The system includes in FIG. 6 an embodiment in which the floating storage vessel (10B) is permanently moored to a mooring buoy (25B) secured by a plurality by anchor legs (26B) to the sea bed (16B).
