Abstract: Method for maneuvering a buoyant body of a wave power converter having a mechanical-electric, mechanical-hydraulic or piezo-electric energy converter which is arranged in the sea under the buoyant body, the buoyant body and wave power converter being connected by a wire, and which buoyant body is provided with at least one ballast tank for controlling the buoyancy of the buoyant body, where the method includes, by means of measuring equipment acquiring information regarding wire tension, filling level/pressure in the ballast tank and stroke of the energy converter, and controlling the buoyancy of the buoyant body by supplying/discharging water/air to/from the ballast tank while at the same time adjusting the tension of the wire by operating a winch arranged in the buoyant body. The invention also relates to a wave power plant for executing the method.

Abstract: Wave-power device, with a plurality of floating bodies (12) arranged in at least two parallel rows for vertical movement caused by wave movements. Each floating body is connected to a generator (22) for the generating of electrical energy during the vertical movement. The floating bodies are jointed to a raft (11) which can be relocated on the water and can be moored at an arbitrary place of use. The floating bodies (12) are connected to vertical supporting bars (14), which are held between an upper lattice-like structure (15, 16) and a lower lattice-like structure (17, 18), and each of the vertical supporting bars (14) is connected to an electric generator (22).
