A method of connecting a first floating structure to the seabed, includes the
steps
of: providing a second floating structure, anchored to first and second anchoring
points respectively on the sea bed via at least two anchor lines, attaching the
second floating structure to the first structure via a pulling device, on the side
of the first anchor line, displacing the first floating structure away from the
second anchoring point towards the first anchoring point, disconnecting the first
anchor line from the second floating structure while maintaining a pulling force
on the second anchor line via the pulling device, and attaching the first anchor
line to the first floating structure. 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.
