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 relates to a mooring tensioning arrangement for a floating structure or a vessel (11), comprising -a mooring line (3, 5, 7) having a first mooring part (3) and a second mooring part (5, 7), divided by a midwater coupling (4, 40, 400, 111), said at least a portion of the mooring line (3, 5, 7) is made of synthetic material, -said mooring line (3, 5, 7) is extending between an anchor (2) arranged on the seabed and a pulling unit (9, 10, 42) arranged separate from the floating structure or vessel (11), said mooring line (3, 5, 7) is extending at least via a fairlead pulley or a chain wheel (8, 80) arranged on the floating structure (11) between the anchor and the pulling unit (9, 10, 42) when the mooring line (3, 5, 7) being pre-tensioned, -a chain stopper (6, 60) being arranged in connection with the mooring line (3, 5, 7) between the anchor (2) and the floating vessel or structure (11) for tensioning the part of the mooring line (3, 5, 7) situated between the floating structure (11) and the ancho
