Abstract: A wave energy plant that includes a semi-submersible platform provided with at least one longitudinal casing that extends from a bow to a stern of the platform and a wave energy machine mounted on the platform. The machine includes a gantry transversely mounted on the casing on the bow of the platform, floats are arranged so as to enable the wave energy to be converted into mechanical energy, i.e. at least one primary float and at least one secondary float, longitudinally offset relative to the primary float and a transformer. The platform includes at least one stabilizer aileron extending transversely within the lower edges of the casings of the platform.

Abstract: Wave power generator (1), which has a semi-submersible platform (2) with at least one longitudinal box (4) that extends from a bow (7) to a stern (8) of the platform (2). The platform (2) has at its bow (7) a stabilizing aileron (12) that extends transversely below a lower edge (9) of the box (4), and at its stern (8) a flotation beam (11) integral with the box (4). A wave energy converter machine (3) is mounted on the platform (2), which includes a gantry (17) mounted transversely on the box (4) at the bow of the platform (2), at least one float (18) that allows the transformation of the wave energy into mechanical energy, the float (18) mounted on an arm (20) mounted in rotation on a shaft (21) integral with the gantry (17), and a converter (23) of mechanical energy from the float (18) into hydraulic energy.
