COLUMN-STABILIZED OFFSHORE PLATFORM WITH WATER-ENTRAPMENT PLATES AND ASYMMETRIC MOORING SYSTEM FOR SUPPORT OF OFFSHORE WIND TURBINES

摘要

PROBLEM TO BE SOLVED: To provide a column-stabilized offshore platform with a water-entrapment plates and asymmetric mooring system for support of offshore wind turbines.SOLUTION: A platform includes a floatation frame 105 that includes at least three columns 102, 103 that are coupled to each other with horizontal main beams 115. A wind turbine tower 111 is mounted on a tower support column 102. Turbine blades 101 are coupled to a nacelle 125 that rotates on the top of the tower. The turbine's gearbox generator and other electrical gear can be mounted either traditionally in the nacelle, or lower in the tower or on the top of the tower support column. The floatation frame includes a water ballasting system that pumps out water to between the columns to keep the tower in a vertical alignment regardless of the wind speed. Water-entrapment plates 107 are mounted on the bottoms of the columns to minimize the rotational movement of the floatation frame due to waves.
