Summary: | The disclosure provides a method for installing a floating foundation in a body of water at a predetermined depth, the method comprising the steps of: providing a construction 5 vessel (2) comprising a hoisting system (4); providing a floating foundation (62) having a positive buoyancy; providing a ballasting frame (60) having a weight, using the hoisting system (4) to lift the ballasting frame (60) and move it to cover the floating foundation; connecting the ballasting frame to the floating foundation; using the hoisting system to lift the assembly of the ballasting frame (60) and the floating foundation (62) and move the 10 combination to an installation location; while the floating foundation (62) is unconnected to a sea floor (40), lowering the assembly into the water using the weight of the ballasting frame (60) to submerge the floating foundation (62) until the floating foundation reaches an installation depth; connecting the submerged floating foundation (62) to subsea anchors using one or more mooring lines (44), allowing the assembly of the frame (60) and the foundation 15 (62) to rise to an operating depth, wherein the foundation is submerged and the one or more mooring lines are under tension; and disconnecting the ballasting frame (60) from the floating foundation. |
