摘要： 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).

摘要： 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.

摘要： The present invention relates to a spread moored vessel for production and/or storing of hydrocarbons. The vessel comprises a laterally extending main deck, a symmetrical mooring arrangement for mooring the vessel to a seabed when the vessel is floating in a body of water and a longitudinal hull. The longitudinal hull further comprises a bow, a midbody, a stern, and a motion suppressing element protruding out from the longitudinal hull, below the vessel's maximum draught. The ratio between a maximum length (Lwl) and a maximum breadth (Bwl) of the longitudinal hull, at the vessel's maximum draught, is between 1.1 and 1.5. The specific hull shape with the particular length/breadth ratio and the motion suppressing element allows for favorable and uniform motions regarding of wave direction in relation to vessel heading.
