Abstract
A structure of a floating, semi-submersible wind turbine platform is provided. The floating wind turbine platform includes three elongate stabilizing columns, each having a top end, a keel end, and an outer shell containing an inner shaft. Each stabilizing column further includes a water entrapment plate at its keel cantilevered in a plane perpendicular to a longitudinal axis of the stabilizing column. The floating wind turbine platform also includes three truss members, each truss member including two horizontal main tubular members and two diagonal tubular members. The truss members connect the stabilizing columns to form a triangular cross-section. An elongate wind turbine tower is disposed over the top end of one of the three stabilizing columns such that the longitudinal axis of the tower is substantially parallel to the longitudinal axis of the stabilizing column.
