Abstract:
Method of connecting an elongate connection member (5, 6; 33, 34; 105) between the seabed and a floating vessel (1, 29, 30, 50, 62, 82, 92, 106), the vessel carrying a connector (7, 20, 32, 57, 63, 83, 93, 102) which is suspended from the vessel by at least two spaced apart suspension members (10, 11, 21, 22) for relative displacement of the connector with respect to the vessel, at least one suspension member being connected to tensioning means (12, 12â€², 13, 13â€²; 25, 26; 45, 46, 47, 48; 51, 52; 73, 74; 90, 91; 96, 97) for exerting an upward force on the connector, characterized in that, the connector is adapted to carry a plurality of connection members, each connection member being suspendable from the connector by an upper end part, the method comprising the steps of:a. attaching one or more connection members to the connector, the added connection members having a predetermined weight; b. increasing the tensioning force of the tensioning means before or after attaching the one or more connection members by an amount that is dependent on the weight of said one or more connection members; and c. repeating steps a and b. until the plurality of the connection members are installed between the vessel and the seabed.
