Abstract
A gravity-based foundation for the installation of offshore wind turbines, manufactured in a floating dock for towing to the final destination thereof, where it is anchored and finally completely submerged below sea level, comprising a concrete floating caisson, in the shape of a prism, with a hexalobular base, divided into several cells by at least one partition with a significantly circular cross section, concentric with a central cell, determining inner vertical cells interconnected with each other and with the exterior, which is closed at the top by a cover or covers that are removed once the foundation is anchored before being filled with a ballast material.

7. A gravity-based foundation for the installation of offshore wind turbines, manufactured in a floating dock for towing to the final location thereof, where it is anchored and finally completely submerged below sea level comprising a floating concrete caisson, in the shape of a straight prism, closed at its base, provided with vertical inner cells interconnected with each other and with the exterior, equipped with emptying and filling devices, which enables self-regulation of the ballast level for anchoring at its final location;
- closed at the top by means of a cover and provided with at least one concrete node in at least one of the cells of the caisson, which defines means of connection of a shaft or structure that joins the caisson to the superstructure, to which in turn the wind turbine is fastened, characterized in that said caisson has a lobular cross section, in a circular arrangement, wherein each of said lobes has a trapezoidal configuration, with a curved-convex outer side, while the inner side is a portion of the partition that defines a significantly circular central cell, each of these lobes being divided into several cells by at least one partition with a significantly circular cross section, concentric with the central cell;
the closing cover or covers having a configuration equivalent to the caisson or to each of said lobes and a support on said caisson that enables the removal of the cover or covers once the foundation is anchored, before being filled with a ballast material. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
- closed at the top by means of a cover and provided with at least one concrete node in at least one of the cells of the caisson, which defines means of connection of a shaft or structure that joins the caisson to the superstructure, to which in turn the wind turbine is fastened, characterized in that said caisson has a lobular cross section, in a circular arrangement, wherein each of said lobes has a trapezoidal configuration, with a curved-convex outer side, while the inner side is a portion of the partition that defines a significantly circular central cell, each of these lobes being divided into several cells by at least one partition with a significantly circular cross section, concentric with the central cell;
