Abstract: The invention concerns a turret assembly (1) for mooring a production vessel (100) to a seabed (105) and for transferring fluids from a subsea flowline to the vessel. The turret assembly comprises a geostationary inner turret unit (5) displaying at least one throughgoing channel (14) extending axially along a longitudinal axis of the inner turret unit, a turret supporting structure (6) rotationally surrounding the inner turret unit and a bearing arrangement situated between the inner turret unit and the turret supporting structure allowing the inner turret unit to rotate relative to the turret supporting structure and to transfer forces from the inner turret unit to the turret supporting structure.

Abstract: The invention concerns a system for mooring a first floating structure (2) to a second structure (1), for example an FAU to an FPSO. The system comprises a main positioning arrangement (4) for maintaining the first floating structure (2) at a predetermined distance (l c ) from the second structure (1). The system further comprises an auxiliary positioning arrangement (3, 3a, 3b) or a back-up system for mooring the first floating structure (2) to an underlying seabed by for example an anchor. This auxiliary positioning arrangement is configured to establish, in case of malfunctioning of the main positioning arrangement, a resultant force (F res ) acting on the first floating structure (2), which force has a magnitude and direction that ensures maintenance of a minimum distance (l min ) between the first floating structure (2) and the second structure (1). The resultant force is the total force acting on the first floating structure and involves for example a surge added mass, a damping force, a horizontal force component from the auxiliary positioning arrangement and a total force from the main positioning arrangement.

Abstract: The invention concerns a vessel (1) for storing and/or producing hydrocarbons and a buoyant turret buoy (6) to be connected to the vessel (1). The outer surface of the bow (2) of the vessel (1) comprises a receiving structure (5) for connecting a buoyant turret buoy (6) to the bow (2). The main part of the receiving structure (5) protrudes from the lower part (4) of the bow (2) in the vessel's (1) direction of travel and an interface of the receiving structure (5) is complementary to an interface of a connecting section (17) of the buoyant turret buoy (6). Further the lower part (4) of the bow (2) is below the water line (w) during connection of the buoyant turret buoy (6) at sea. The invention also concerns a method for connecting the buoyant turret buoy (6) to receiving structure (5) of the vessel (1).

Abstract: The invention concerns a cargo transfer vessel (3) for transferring fluid between an offshore production facility and a tanker and a method for transferring the fluid. The cargo transfer vessel comprise a hull (20) having a first and a second outer longitudinal hull side; a deck (30), propulsion means for actively maintaining the cargo transfer vessel at a predetermined distance from the offshore production facility and the tanker during fluid transfer operations and fluid transfer means for transferring fluid between the offshore structure and the tanker. The vessel is further characterized in that the hull comprises a main hull member and at least one protruding hull member (13) arranged below the cargo transfer vessels water line at each of the outer longitudinal hull sides for suppressing roll of the vessel, wherein the at least one protruding hull member extends at least partly along the hulls longitudinal length, i.e. from the start of the vessel's bow to the end of the vessel's aft.
