  • Publication number: 20210188402
    Abstract: The disclosed invention relates to a connecting system for connecting a mooring line to a body comprising a first part being attached to the mooring line and connected with a pin having two ends, to a second part being attached to the body and having an arrangement for guiding the pin into a hang-off structure in the second part where the hang-off structure substantially comprises at least one hook. The system is characterized by a connecting structure for a temporary pulling means mounted on the first part in transverse direction to its longitudinal axis and eccentrically to an axial center of gravity of the first part. The invention relates also to a method regarding the application of the system.

  • Patent number: 10982644
    Abstract: A power harvesting device comprising at least one rotor mounted rotatably on a corresponding fixture on a base structure is disclosed. The device is at least partially submerged in a moving fluid and arranged to convert tangential components of fluid dynamic forces of the moving fluid into a first torque component onto the rotor through rotor vanes. In addition, rotor blades are arranged on or between the first rotor vanes to deflect axially moving fluid into a tangential direction to create a second torque component onto the rotor in the same direction as said first torque component. A system comprising a plurality of power harvesting devices with common power transfer means is also disclosed.

  • Patent number: 10787232
    Abstract: A structural suspension of radial turret bearing wheels in a turret bearing comprises a rail support structure mounted on a turret bearing support structure, a circular rail mounted to the rail support structure, and a plurality of radial wheels running on the mainly vertical inner side of the rail. The suspension includes a vertical flexible shaft, for each radial wheel, supported by an upper and lower support with a part of the shaft protruding with the radial wheel mounted close to the outer end. The inner side of the rail is a frustum with the shortest radius at the top and an aperture of 2, and the outer mainly planar contacting surface of the wheel has an angle ? relative to the rotational axis of the wheel, and is overlaid with a convex curvature across the contacting surface.

  • Patent number: 8418639
    Abstract: A mooring system for a vessel and a method of mooring a vessel are provided. The mooring system comprises a turret structure; a swivel unit mounted on the turret structure; a bearing assembly for rotatably mounting the turret structure at deck level of the vessel such that the turret structure extends into a moonpool of the vessel and such that the swivel unit is disposed above deck level; a plurality of conduits for fluid communication disposed in the turret structure; a buoy structure retrievable into the moonpool of the vessel and connectable to the turret structure; a locking assembly for mechanically locking the buoy structure to the turret structure; and wherein the turret structure is rotatable as one to align the conduits to corresponding riser valve structures on the buoy structure prior to mechanically locking the buoy structure to the turret structure.
