A vessel includes a hull with a turret, a cavity in the turret and a mooring buoy releasably attached in the cavity, the buoy including a buoyant body and carrying a number of risers, extending to a subsea hydrocarbon well and a number of anchor lines connected to the sea bed, wherein upon connection of the buoy to the cavity, the buoy is attached to a pulling member connected to a winch on the vessel for lifting of the buoy. Each anchor line and/or riser at its upper end is connected to a stopper member, the stopper member being attached to the pulling member, wherein during lifting, each anchor line and/or riser and the stopper member are movable relative to the buoyant body in a length direction of the anchor lines and/or risers, and wherein after connection of the buoyant body to the cavity, the stopper member is engaged with an abutment member on the buoyant body to support the anchor line and/or riser weight off the body. |

1. 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. |
