  • 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: 9068550
    Abstract: An assembly for generating energy from sea currents comprises a main floating body to be oriented across the direction of the sea current, a rotor assembly depending from the main floating body, at least one stabilising member extending substantially sideways from the main floating body and mooring lines for anchoring the assembly. Each stabilizing member is attached to the main floating body at a position substantially corresponding with the position of attachment of a mooring line. Further an assembly for generating energy from sea currents comprises a main floating body to be oriented in parallel to the direction of the sea current, at least two outriggers extending substantially sideways in opposite directions from the main floating body, a rotor assembly depending from the outrigger means and mooring lines for anchoring the assembly. The mooring lines are attached to the main floating body at or near the opposite frontal ends thereof.
