GRAVITY-BASED FOUNDATION FOR OFFSHORE WIND TURBINES

Gravity foundation for offshore wind turbines, fabricated using floating dock technology, comprising a caisson (1) with a circular cross-section, with hollow cells (11, 12, 13) for interior voiding, closed on the top by one or more covers (16), whose central cell (13) is extended into a post-tensioned concrete mast (2), on which the metal tower (4) that supports the wind turbine is attached. The cells (11, 12, 13) of the caisson are filled with solid ballast (8) for the purpose of lowering its centre of gravity, such that the design of the foundation as a whole can be towed and sunk on the open sea without the need for special vessels or the use of additional means of flotation, because it has sufficient naval stability during all of the its phases.
