Abstract: Method for installation of an offshore tower, which comprises: providing a tower mast, piles, anchoring means, a platform with securing means, and buoyancy means with securing means; fastening piles to platform; fastening mast to platform in the use position; providing actuation and/or braking means between piles and platform; providing a platform between lower zone and upper zone; anchoring means to piles and to platform; launching buoyancy means; launching base assembly (platform, mast, piles, anchoring means); securing base assembly to buoyancy means using securing means; transferring transport assembly to tower location; actuating actuation and/or braking means until piles are fixed in the seabed; fastening piles to seabed; actuating actuation and/or braking means until platform is on a level with pile upper zone; mounting wind turbine on mast; removing securing means and withdrawing buoyancy means from platform; and tensioning anchoring means.

Abstract: The purpose of the invention is to provide a multi-platform tower that allows production costs to be significantly reduced, since the tower is suitable for different types of turbines. For this purpose, the improvements consist in obtaining a profile which is based on frustoconical sections having various inclinations and which corresponds geometrically with a load envelope obtained from the superimposition of theoretical profiles of respective towers designed specifically for a plurality of different turbines. Given that the lower part of the turbine comprises securing means having a different diameter, it is necessary to include a series of adaptors or reels (4-4?) having a frustoconical configuration and which allow the tower to be adapted to any type of turbine. If necessary, a second adaptor (11), formed consisting of ring in the form of a wedge, could be included, the adaptor modifying the angle of the plane in which the blades rotate, thereby distancing the free end of the blades from the tower.
