Oscillating Wave Surge Converter

Technology Description The device is a spring mass oscillating system consisting of two water chambers connected via springs to a buoy that is floating on the ocean surface. This buoy is in addition connected via springs to a mooring buoy below the ocean surface. The spring mass system has a natural oscillating frequency that is equal to or lower than the frequency of the ocean waves. This will result in transfer of energy from the ocean waves into the spring mass system. The energy is extracted from the system by braking the relative movement between the masses. The brakes use braking forces equivalent to the critical damping forces of the mass spring system and convert the braking forces into electrical energy.



Mooring Configuration The device is either installed between 2 mooring buoys which are coupled to anchors at the sea bottom or between a mooring buoy and an onshore mooring point
Optimum Marine/Riverline Conditions The device can be made in different sizes which should be based on the average wave height at the installation sites
