Abstract:
A vessel (1) comprising a riser or tendon tensioning construction having at least two spaced apart mounting points (19, 20) and a connector (15) carrying two or more risers or tendons (3,4) which are with one end attached to the seabed and with the other end attached to the connector (15), the connector (15) being suspended from the mounting points by at least two suspension members (12,13) which are movably connected to the mounting points (19,20), the suspension members (12, 13) being with a first end attached to respective positions on the connector (15) and with their second end to a respective tensioning member (16,17) for exerting a tensioning force on the risers or tendons,wherein the tensioning member (16,17) extends one of outside the hull (23) of the vessel and through a well (28) in the vessel so as to be at least substantially located below water level, and wherein the suspension members and/or their respective tensioning members are below water level mutually connected for reducing swinging motions of the tensioning members.
