Abstract

Abstract A mooring for a vessel (1) floating on the surface (22) of a body of water and anchored to the floor (21) of that body of water having a rotary member (28) attached to a tension riser (6), the rotary member (28) being located above the surface of the body of water and being supported by a remotely positioned submerged buoyancy chamber (4) by means of a support structure (5) and two rigid yokes (2, 3) interconnecting the support structure with the integrated buoyancy chamber and the vessel, is disclosed. The support structure (5) is rotational with respect to the tension riser (6) and the rigid yokes (2,3) are pivotable about horizontal axes at their connection points with the vessel and the support structure with integrated buoyancy chamber. The mooring incorporates means to transfer fluids or gases between a pipeline on the floor of the body of water and the vessel.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 124 words
1 . A mooring for a vessel floating on the surface of a body of water comprising: - a single anchor point located on the floor of said body of water; - a rigid tension riser attached to said anchor point and supported by a support structure with integrated buoyancy chamber by means of a swivel member; - two rigid yokes attached to said support structure with integrated buoyancy chamber by means of hinges pivotable about horizontal axes; said two rigid yokes being connected to said vessel by means of hinges pivotable about horizontal axes; - means for full rotation of said vessel, said tw: rigid yokes and said support structure with integrated buoyancy chamber around said rigid tension riser about a vertical axis.
Claim 2
Dependent Claim 124 words
1 . A mooring for a vessel floating on the surface of a body of water comprising: - a single anchor point located on the floor of said body of water; - a rigid tension riser attached to said anchor point and supported by a support structure with integrated buoyancy chamber by means of a swivel member; - two rigid yokes attached to said support structure with integrated buoyancy chamber by means of hinges pivotable about horizontal axes; said two rigid yokes being connected to said vessel by means of hinges pivotable about horizontal axes; - means for full rotation of said vessel, said tw: rigid yokes and said support structure with integrated buoyancy chamber around said rigid tension riser about a vertical axis.
