Claim:
A vessel ( 14 ) comprising: a hull ( 3 ) with a turret ( 1 ), a cavity ( 16 ) in the turret and a mooring buoy ( 11 ) releasably attached in the cavity, the buoy comprising a buoyant body ( 57 ) and carrying a number of risers ( 12 ), extending to a subsea hydrocarbon well ( 15 ) and a number of anchor lines ( 10 , 10 ′) connected to the sea bed, wherein upon connection of the buoy to the cavity, the buoy is attached to a pulling member ( 19 ) connected to a winch ( 20 ) on the vessel ( 14 ) for lifting the buoy, wherein each anchor line ( 10 , 10 ′) and/or riser ( 12 ) at its upper end is connected to a frame ( 44 , 55 , 55 ′, 56 , 65 , 66 , 66 ′, 69 , 69 ′), the frame being attached, during lifting, to the pulling member ( 19 ), wherein during lifting of the anchor lines and/or risers by the pulling member and the frame, the anchor lines and/or risers and the frame are movable relative to the buoyant body ( 57 ) in an upward and downward length direction of the anchor lines and/or risers such that the buoyant body rises upward by its buoyancy, and wherein in the disconnected state of the buoy and after connection of the buoyant body to the cavity ( 16 ), the frame forms a stopper member ( 44 , 55 , 55 ′, 56 , 65 , 66 , 66 ′, 69 , 69 ′) for engaging an abutment member ( 48 , 61 , 70 ) on the buoyant body to support the anchor line and/or riser weight off the body.
