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.
