A floating foundation includes a plurality of unit modules that can be fabricated in an efficient manner and then assembled, on shore or afloat near the deployment location. The floating foundation can be applied to various offshore energy systems, such as wind power generation, and in deployment locations with limited infrastructure.

Floating offshore foundation including modular components, method for modular assembly of the floating offshore foundation, and a reconfigurable system for the floating offshore foundation

Provided is a floating foundation for supporting a wind power generation system including a stabilized power cable. In one embodiment, the floating foundation includes a column extending upwardly and couplable at a top end thereof to a base of the wind turbine, at least one power cable for exporting power generated from the wind turbine to another floating foundation or to an offshore/onshore station, and a plurality of buoyancy modules disposed along the at least one power cable. Power cables between a plurality of floating foundations and/or power station may be supported by buoyant modules such that the power cable is located in an optimal submergence range of the water body in which the floating foundations are deployed.

Provided is a semi-submersible floating foundation for supporting a wind power generation system. In one embodiment, the floating foundation includes a plurality of outer buoyant columns equidistantly spaced around a center buoyant column that are connected by buoyant structural pontoons. The center buoyant column supports a horizontal axis wind turbine (HAWT) or a vertical axis wind turbine (VAWT) energy system. The floating foundation includes motion attenuating extensions with or without porosity attached to the sides of the pontoons. Deepwater station-keeping system of the floating foundation includes a plurality of disconnectable and reconnectable taut or semi-taut mooring lines coupling one or more outer buoyant columns to seabed anchors. Inter-array power cable between a plurality of floating foundations may be free hanging or supported by buoyant modules. Export power cable from a floating foundation to seabed toward shore may be free hanging or supported by buoyant modules.
