The invention relates to a system for mooring or anchoring wind turbines at sea, which consists of radial-blade, horizontal-axis wind turbines disposed on a vertical or horizontal pontoon or float submerged below the orbital depth, or close thereto, and which are moored by cables or chains to concrete blocks, or anchored by anchoring elements or bolts to the sea bed or lake bed. The wind turbines are constantly and automatically directed, in the manner of a wind vane, by the action of the wind and the water current and are vertically and horizontally stabilised, the wind turbine shafts driving electric generators, air compressors or hydraulic pumps. The vertical pontoon consists of a tubular element having a cylindrical shape or an oval cross-section with an aerodynamic profile. The horizontal pontoon is disc-shaped with an aerodynamic profile. Both types of pontoon are hollow and filled with air or a plastic polymer foam.
