A connector assembly for use on a vessel to eliminate relative vertical movement between the vessel and a riser (20) attached to a sub-sea well, the connector assembly comprising a first connector part (4) to be secured to the riser (20), a second connector part (3) to be secured to the vessel, the second connector part (3) being connectable to the first connector part (4) without relative axial movement and disconnectable from the first connector part (4) to allow relative axial movement between the first and second connector parts, and an alignment mechanism (5, 15, 18, 30) which, when the first (4) and second (3) connector parts are disconnected, maintains the connector parts in axial alignment and spaced apart in a non-sealed manner by a gap (30) the size of which varies with relative axial movement of the first and second connector parts. |
