Abstract

Abstract A floating offshore loading terminal has an upper rotary hull structure rotatably mounted on a moorable lower base structure with upper and lower fluid conduit systems communicating through a swivel coupling between the structure. A motor drive rotates the upper rotary hull structure to wind flexible buoyant cargo transfer hoses circumferentially into and from a storage spool surrounding the hull structure.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 204 words
A floating offshore loading terminal for transferring flowable material between a vessel and a storage facility through an underwater pipeline, comprising: a moorable base structure; a buoyant rotary hull structure rotatably coupled on and surrounding said base structure, and having a peripheral configuration adapted for winding buoyant cargo transfer hose; lower conduit means supported within said base structure coupled in flow communication with said underwater pipeline; upper conduit means supported within said rotary hull structure coupled in flow communication with buoyant cargo transfer hose; means defining a swivel coupling for establishing rotatable flow communication between said upper and said lower conduit means; buoyant cargo transfer hose coupled to said upper conduit means adjacent to periphery of said rotary hull structure; motor drive means for rotating said hull structure relative to said base structure to wind said hose about the periphery of said hull structure; and, upper and lower hose retaining structures extending radially outward about the periphery of said rotary hull structure, said hose retaining structures being vertically spaced from one another above and below the waterline by at least the cross section of said buoyant cargo transfer hose to provide a horizontal spooling arrangement within which said hose is wound in multiple layers.
Claim 2
Dependent Claim 204 words
A floating offshore loading terminal for transferring flowable material between a vessel and a storage facility through an underwater pipeline, comprising: a moorable base structure; a buoyant rotary hull structure rotatably coupled on and surrounding said base structure, and having a peripheral configuration adapted for winding buoyant cargo transfer hose; lower conduit means supported within said base structure coupled in flow communication with said underwater pipeline; upper conduit means supported within said rotary hull structure coupled in flow communication with buoyant cargo transfer hose; means defining a swivel coupling for establishing rotatable flow communication between said upper and said lower conduit means; buoyant cargo transfer hose coupled to said upper conduit means adjacent to periphery of said rotary hull structure; motor drive means for rotating said hull structure relative to said base structure to wind said hose about the periphery of said hull structure; and, upper and lower hose retaining structures extending radially outward about the periphery of said rotary hull structure, said hose retaining structures being vertically spaced from one another above and below the waterline by at least the cross section of said buoyant cargo transfer hose to provide a horizontal spooling arrangement within which said hose is wound in multiple layers.
Claim 3
Dependent Claim 25 words
The floating offshore loading terminal of claim 1 wherein: said rotary hull structure has a substantially rounded outer periphery for winding said buoyant transfer hose.
Claim 4
Dependent Claim 44 words
The floating offshore loading terminal of claim 2 wherein: the portion of said upper conduit means adjacent the point at which the buoyant cargo transfer hose is attached extends outward from said rotary hull structure approximately tangential to the adjacent portion of the periphery.
Claim 5
Dependent Claim 61 words
The floating offshore loading terminal of claim 3 further comprising: restraining means extending outward from the rotary hull structure and attached to said buoyant cargo transfer hose adjacent its coupling to said upper conduit means for maintaining the intermediate end portion of the hose when extended in an approximate tangential alignment with the adjacent rounded periphery of the rotary hull structure.
Claim 6
Dependent Claim 50 words
The floating offshore loading terminal of claim 4 further comprising: an independently rotatable bollard structure mounted on the upper surface of said rotary hull structure concentric with its rotational axis; and, bollard motor drive means interconnecting said bollard and said hull structures for driven rotation relative to said hull structure.
Claim 7
Dependent Claim 39 words
The floating offshore loading terminal of claim 5 wherein: said bollard structure includes an outwardly extending mooring line storage platform extending outward from the lower edge of said bollard structure for supporting mooring lines coiled about said bollard structure.
Claim 8
Dependent Claim 36 words
The floating offshore loading terminal of claim 2 wherein: said outwardly extending structure includes a pair of spaced ring fenders, each of said fenders including a plurality of radially extending spaced vanes supporting a circumferential ring.
