<p>The invention relates to a method of connecting a first floating structure (1, 16, 25, 41) to the seabed, comprising the steps of: providing a second floating structure (2, 18, 26, 40), anchored to first and second anchoring points (6, 7; 22, 23; 32, 33; 47) respectively on the sea bed via at least two anchor lines (4, 5; 19, 20; 30, 31; 43, 45), attaching the second floating structure to the first structure via a pulling device (13, 24, 35, 46), on the side of the first anchor line, displacing the first floating structure (1, 16, 25, 41) away from the second anchoring point (7; 22, 33, 47) towards the first anchoring point (6, 23, 32), disconnecting the first anchor line (4, 20, 30, 45) from the second floating structure (2, 18, 26, 40) while maintaining a pulling force on the second anchor line (5, 19, 31, 43) via the pulling device, and attaching the first anchor line (4, 20, 30, 45) to the first floating structure (1, 16, 25, 41). By interconnecting a temporary buoy to the vessel to be anchored via a tension member, the anchor lines of the buoy and the vessel can remain under tension at all times whereby damage to the anchor lines is prevented. The timepath of fabrication and installation of the risers and the vessel, such as a FPSO, is made more flexible and less critical terms of first oil and contingencies and the installation costs can be reduced.</p> |
