A high pressure swivel is disclosed which includes swivel modules each having a stationary inner structure and a rotatable outer structure that can rotate about the inner structure. The inner structure of each module has the same number of vertical passages as the others. The inner structure of each module has a circumferential flange on the top and on a bottom lip so that each swivel unit can be secured to another swivel in its top or bottom with clamps around the flanges. The inner structures are rotatably positioned with respect to each other when assembled so that a vertical passage from a stationary base manifold to an outlet on the rotatable outer structure is formed. Various combinations of standard swivel modules can be assembled to accommodate specific swivel stack requirements for flow capacity and separate or comingled flow paths.

A fluid swivel including a stationary inner housing assembly and a rotatable outer housing operatively connected to the inner housing assembly. The outer housing includes an annular passage with upper and lower surfaces. Upper and lower seals are positioned between the inner housing assembly and the outer housing in seal recesses. A passage in the inner housing assembly provides fluid of pressure to the annular passage. The fluid exerts a first force axially inward on outer housing outer surfaces, and a larger second force axially outward on the annular passage's upper and lower surfaces. The second force is greater than the first force so upper and lower ring portions deflect outward such that the elastic axial deflections of the inner housing assembly match the axial deflections of the outer housing, thereby causing the axial clearances between the components at the upper and lower seals to remain almost the same.

A fluid swivel (10A) that includes a stationary annular structure (16A, 17A) defining upper and lower annular seal slots (61, 62), and a rotatable outer housing (20A) operatively connected to the stationary annular structure (16A, 17A), the outer housing defining a radial groove (30) that has upper and lower surfaces. Upper and lower seals (40, 41) are positioned between the stationary annular structure (16a, 17a) and the rotatable outer housing (20a) and disposed in the upper and lower seal slots (61, 62).

A chain support, hinged on two perpendicular axes to allow chain movement in two perpendicular planes is disclosed. The apparatus provides an improved arrangement to allow chain to be pulled at an angle above the chain support while maintaining straight pull across a stopper mechanism.
A turret/vessel bearing arrangement and method for replacing bearings in situ without removing other bearings. The bearings are capable of being separated. A removable axial spacer secures the vessel and the turret into engagement with the upper and lower thrust bearings. Removal of the spacer allows increased separation between vessel and turret flanges that sandwich the thrust bearings. The mid radial bearing assembly includes one or more radially arranged bearing pads that allow for limited axial displacement of the turret with respect to the vessel during thrust bearing replacement while still bearing radial loads and allowing rotation. The addition of a temporary thrust bearing allows the vessel to weathervane about the turret while thrust bearing are replaced in situ.

A radial bearing arrangement (2) including a turret (14) carried by a vessel (10), the turret (14) having an outer annular rail (38) secured about its outer circumference. The radial bearing arrangement (2) also includes a plurality of rollers (104) attached to the vessel (10) via bearing assemblies (74). The bearing assemblies (74) are arranged and designed to urge the rollers (104) into contact with the annular rail (38), and to limit radial movement of the vessel (10) relative to the turret (14). A plurality of bearing pads (114) are attached to the vessel (10) and positioned circumferentially between the bearing assemblies (74). The bearing pads (114) are arranged and designed to contact the rail (38) under peak loading to limit radial movement of the vessel (10) relative to the turret (14).
A single point mooring includes a yoke-shaped articulated arm assembly affixed to the seabed by a fixed foundation or mooring base assembly, and a mooring support structure retrofitted to a vessel The articulated arm is connected to the base by a triaxial articulation joint for accommodating yaw, pitch and roll To moor the vessel, the arm is connected to the mooring support structure with weighted pendants on port and starboard sides The pendants are suspended at an adjustable elevation with respect to the mooring support structure, thus allowing the mooring system to be used at varying water depths A combined connection bracket hosts both pendant linkages and umbilicals or hoses for speeding the process of connecting and disconnecting a vessel from the mooring system A removable anchor, such as a suction pile, fixes the mooring system to the seabed, allows the system to be easily redeployed to another location
An LNG terminal is disclosed which includes an offshore mooring turret, an LNG storage vessel operatively coupled to the mooring turret, the LNG storage vessel including at least one LNG storage tank for the storage of liquid natural gas and a regasification vessel operatively coupled to the LNG storage vessel. A method of operating an offshore LNG terminal is also disclosed which includes obtaining liquefied natural gas from at least one LNG storage tank on an LNG storage vessel that is operatively coupled to a mooring turret, regasifying the liquefied natural gas from the LNG storage vessel using a regasification vessel operatively coupled to the LNG storage vessel, and supplying the regasified gas to at least one subsea pipeline via the mooring turret.
Apparatus for mooring a vessel to the seabed comprising a turret that is connected to the vessel for rotation about a vertical axis defined thereby and axial/radial bearing structure that can absorb axial and radial forces. The turret is connected at its lower end to a chain table or buoy for attaching mooring lines. The turret is disposed inside the hull of the vessel within a fixed tube. An outer ring of the axial/radial bearing is mounted to a rigid ring, which in turn is fastened by a flexible tube to the lower end of the fixed tube at an elevation below the rigid ring. The fixed tube encloses the turret with clearance. Deformation of the hull due to wind and waves is inhibited to the bearing, because hull deformation is absorbed by the flexible tube that couples the rigid ring to the vessel hull.
A mooring system comprising a submerged buoy releasably connected to a vessel adjacent its keel by a structural connector. The structural connector consists of a cylindrical sleeve coaxially movable with respect to a cylindrical housing by circumferential actuators. The lower ends of the connector sleeve and connector housing capture a number of collet segments circumpositioned therebetween that radially pivot in and out as the connector sleeve is moved axially within the connector housing. The lower ends of the collet segments extend downward to a connector hub on the buoy and releasably engage a groove therein, dogging the bearing hub against the vessel. A combined bearing assembly that supports both axial and radial loading revolvably connects the buoy to a moored chain table.
