New Wave Power Device Will Attach to Offshore Wind Turbine

We’ve profiled different methods of generating power from the waves on a number of occasions, and usually there’s one commenter who suggests that someone develop a solution that attaches to offshore wind turbine towers. Well, your pleas have been answered (or maybe those comments were plants...). Green Ocean Energy Ltd has announced that it has developed the Wave Treader:Mounted to Turbine Base, 500 Kilowatts Each
Based off the Aberdeen, Scotland-based company’s Ocean Treader, the Wave Treader is designed to mount onto the tower of an offshore wind turbine:

The Wave Treader concept utilizes the arms and sponsons from Ocean Treader and instead of reacting against a floating Spar Buoy, will react through an Interface Structure onto the Foundation of an Offshore Wind Turbine. Between the Arms and the Interface Structure hydraulic cylinders are mounted and as the wave passes the machine first the forward Sponson will lift and fall and then the aft Sponson will lift and fall each stroking their hydraulic cylinder in turn. This pressurizes hydraulic fluid which is then smoothed by hydraulic accumulators before driving a hydraulic motor which in turn drives an electricity generator. The electricity is then exported through the cable shared with the Wind Turbine.

Each Wave Treader is rated at 500kW and can turn to face into the waves to ensure optimal power generation. The first full-size prototype is expected to be built later this year, with commercial versions being made available in 2011.
