Abstract
A vessel includes a hull, a shaft extending from an upper part of the hull to a bottom of the hull, a turret being rotatably supported in the shaft via a turret bearing, a manifold support structure carrying one or more conduits being rotatably supported on the turret via a manifold bearing. The turret includes a cavity for receiving a mooring buoy carrying one or more risers and one or more vertically displaceable actuation members near the manifold bearing for vertically displacing the manifold support structure relative to the turret between a rotational position in which the manifold support structure can rotate relative to the turret via the manifold bearing and a locked position in which the bearing support structure is rotationally locked relative to the turret.
