Ocean Harvesting is currently developing generation 6 of its wave energy converter InfinityWEC, in close collaboration with ball screw manufacturer - NSK. A ball screw is a very good actuator providing a high ratio between linear motion and rotation to the generator, high efficiency, low weight and long life. However, ball screws are sensitive to the side forces and bending moments in the PTO caused by the surge motion of the buoy and high speeds that may occur in large waves. This challenge in...

The InfinityWEC wave energy converter has been upgraded with an innovative solution that uses hydrostatic pressure to provide a constant pre-tension force in the power take-off (PTO), reducing size, weight, complexity, and ultimately cost of electricity production (LCoE). upgraded InfinityWEC design In the upgraded InfinityWEC design, the PTO hull is split into two halves, with the top half moving up and down with the buoy, while the bottom half is fixed to the anchor. Similar solutions have b...
