GRAVITY FOUNDATION FOR THE INSTALLATION OF OFFSHORE WIND TURBINES AND METEOROLOGICAL TOWERS

摘要

The invention relates to a gravity foundation for the installation of offshore wind turbines and meteorological towers, produced on a floating dock to be towed to its final location, where it is sunk, ultimately remaining entirely submerged below the level of the sea. The gravity foundation comprises a floating concrete box (1) in the form of a straight prism with rectangular bases, provided with internal vertical cells (6) connected to one another and to the exterior, said cells being provided with emptying and filling devices permitting the self-regulation of the level of ballast for sinking at its final location, which box is closed on top using a slab (2) that covers the entire surface of the box (1) with the exception of at least one cell (61) in which a concrete node (3) is formed in which a shaft (4) or a support structure (7) is fixed, joining the box (1) to the superstructure (5) on which the wind turbine or meteorological tower is then secured.
