Claim:
Vessel ( 14 ) comprising a hull ( 3 ), a shaft ( 2 ) extending from an upper part ( 40 ) of the hull to a bottom ( 41 ) of the hull, a turret ( 1 ) being rotatably supported in the shaft via a turret bearing ( 4 , 5 ), a manifold support structure ( 31 ) carrying one or more conduits being rotatably supported on the turret via a manifold bearing ( 32 ), the turret comprising ( 1 ) a cavity ( 42 ) for receiving a mooring buoy ( 11 ) carrying one or more risers ( 12 ) and one or more vertically displaceable actuation members ( 33 ) near the manifold bearing ( 32 ) for vertically displacing the manifold support structure ( 31 ) relative to the turret ( 1 ) between a rotational position in which the manifold support structure ( 31 ) can rotate relative to the turret via the manifold bearing ( 32 ) and a locked position in which the bearing support structure ( 31 ) is rotationally locked relative to the turret.
