An installation comprising a wave power apparatus and a support structure therefor

A wave power apparatus (302) includes a plurality of rotationally supported arms (322) , each of which carries a float (324) at its free end, so that a translational movement of the float caused by a wave results in rotation of the arm. The apparatus comprises power conversion means (128,130) for converting power transmitted from the wave to the arms into electric power, e.g. a hydraulic system. The plurality of apparatus is arranged in a row such that a wave passing the row of arms causes the arms to successively pivot with a mutual phase shift. Thereby, an even power output may be achieved, and the need for frequency converters may be reduced or eliminated. Preferably, each arm is connected to a hydraulic cylinder (328) of the hydraulic system, whereby a plurality of arms feed hydraulic medium into the hydraulic motor or motors through common hydraulic conduits (180).
