The invention relates to a structure (2) for supporting a wind turbine tower (1) provided with a housing (7) for fitting therein the foot of the tower (1), a main axis (Γ) being defined on the platform (2) which coincides with a main axis of the tower (1), and which comprises a body with a constant cross-section and internal walls (8) and intermediate walls (10) joined by internal radial ribs (11) perpendicular to the internal wall (8) whose plane passes through the main axis (Γ), such that at the intermediate wall (10) first joining nodes (12) are defined between the intermediate wall (10) and radial ribs (11), the intermediate wall (10) and an external wall (9) being joined by reticular ribs (14 and 15). This structure provides an optimal transmission of forces. The invention likewise relates to methods for manufacturing, assembling and installing the structure.

A support structure for a wind power generation device comprises: a plurality of floats that can float on the surface of water or in the water; a connecting member having one end connected to one of the floats and the other end connected to another of the floats among the plurality of floats; a support platform that is provided between the plurality of floats and supports the bottom end of a tower part of the wind power generation device; a linear wire member having one end connected to one of the floats and the other end connected to the support platform; and a support member that is provided on the floats or on the connecting member and supports the tower part, which is supported on the support platform, from a lateral direction while the support member being movable along the axial direction of the tower part.

The invention has for object a system and a method for the realization of floating platforms formed by the aggregation of floating forms in reinforced concrete, the union set of the modules is made integral forming a single plate inserting and pulling special steel cables that cross the entire platform in sheaths arranged in the walls of the modules themselves, the pulled cables, locked in this position, compress the plate to increase resistance, the present method and system are also characterized by the fact that the quota of the platform does not vary with the tides and the loads to which it is subjected.
