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.

Abstract: A semi-submersible platform (1), having at least two longitudinal floating box structures (2), the box structures (2) having solid side walls (3, 4) defining a central channel (5) that extends from a bow end (6) to a stern end (7) of the platform (1); at least one beam (10) transversely coupling the box structures (2); and at least one stabilizer aileron (11) that extends transversely below the lower edges (9) of the box structures (2).

Abstract: The invention relates to a device for recovering the energy of sea waves comprised of a floating structure comprising:—a rigid structural element (1) maintained floating on the sea thanks to at least one buoy or floater referred to as structural (2, 2?), and—at least one mobile floater (3, 3?) with regards to the structural element and cooperating with a means of generating recoverable energy (4; 14, 15, 16) under the effect of the movement of the waves, said means (4; 14, 15, 16) being fixed to the structural element. According to the invention, at least one mobile floater (3, 3?) is connected to the structural element by at least one rigid arm (5, 5?) mounted rotatingly around an axis substantially parallel to the surface of the sea and said means of generating energy (4; 14, 15, 16) is directly or indirectly linked to said rigid arm.

Abstract: A device for recovering the energy of sea waves, which comprises at least one floating structure intended to float on the surface of the water. Said floating structure carries at least one member (2) suspended above the surface of the water, the structure of which is designed to generate recoverable energy through the variation in height of the surface of the water relative to said member, under the effect of the ascending and descending movement of the waves. Application to recovering wave energy.
