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.
