  • Patent number: 11708132
    Abstract: A mooring assembly for a vessel includes a turret with a lower receptacle cone receiving a buoy, mooring lines attached to the buoy, and risers. The buoy includes a plurality of pivot legs positioned on a lower part of the buoy, wherein the legs are pivotably connected to the buoy through a horizontally extending pivot axis to pivot in a radial plane with respect to the buoy between a first position with the buoy in the cone of the turret, in which the legs extend mainly vertically downwards and engage an inner surface of the cone, and a second position with the buoy outside of the cone, in which the legs extend mainly horizontally outwards. The lines are attached to the legs and each leg has such a length that in the first position its end is located at a level below the lowermost end of the cone.

  • Patent number: 7510452
    Abstract: A disconnectable mooring system for a vessel comprises a mooring buoy member and a turret structure mounted in a moonpool of the vessel. The mooring buoy member is anchored to the seabed and has a plurality of passages each adapted to receive a riser. The turret structure has a receptacle for receiving the buoy member and a locking device for locking the buoy member in the receptacle. The turret structure accommodates a plurality of conduits to be connected to risers installed in passages of the buoy member and the turret structure is rotatably supported in the moonpool of the vessel by at least a bearing assembly mounted above sea level. The buoy member is provided with a conical outer casing and the receptacle of the turret structure has a cone shape corresponding to the conical outer casing of the buoy member. The turret structure comprises a turntable carrying the conduits to be connected to the risers.
