Abstract: A floating platform for wind energy extraction, comprising a structure (S) which is the support for the assembly (P) made up of a wind turbine tower (3), a nacelle (2) and its corresponding rotor blades (1), whereby the support structure (S) is formed by an upper structure (4) which joins the assembly (P) to the floating tank (5), which is, in turn, joined by means of a lower structure (7) to the ballast tank (8), and whereby said ballast tank (8) is configured to control the assembly's centre of gravity and adjust the flotation line by the distribution of mass.
