Abstract: A floating platform for a wave energy converter (WEC), comprising a hollow body, in which energy converting machinery may be positioned, characterised in that the floating platform has an underside facing the water in use, an upper side facing the opposite direction and a first long-side forming a front and a second long-side forming a back, and two short-sides, wherein at least one aligning means is provided, the aligning means is configured to align the front of the floating platform with the wave front, i.e. perpendicular to the direction of the wave, wherein the front of the floating platform is at least 20 m long.

Abstract: A power take-off apparatus for a wave energy converter of point absorber type, includes a cylinder attachable to a floating device, a piston that reciprocates inside the cylinder and has a piston rod attachable to a mooring, at least one penstock with a first end in communication with a second end of the cylinder through a first opening, and a second end having a second opening, and a housing above a cylinder first end. The housing communicates with the penstock through the second opening and with the cylinder through a third opening in the housing such that the cylinder, penstock and the housing form a closed loop for a fluid in the power take-off apparatus. A water turbine is arranged inside the housing so that working fluid entering the housing from the at least one penstock causes rotation of the water turbine to drive an electrical generator connected thereto.
