A floating wind turbine platform includes at least three stabilizing columns, where each stabilizing column has an internal volume for containing ballast. The floating wind turbine platform also includes a tower having mounted in vertical alignment over one of the columns, a turbine rotor coupled to an electrical generator mounted proximate to the upper end of the tower, main beams interconnected to the stabilizing columns, and water-entrapment plates attached to the lower ends of the stabilizing columns. The floating wind turbine platform further includes a ballast control system including an alignment sensor configured to detect a rotation of the tower, and a controller coupled to the alignment sensor for directing a transfer of the ballast from an internal volume of one column to another column upon the alignment sensor detecting rotation of the tower to adjust a vertical alignment of the tower.
