Wave Energy in the North Sea


The only reciprocating movement of large parts is the piston in its house, providing effficient hydraulic power transfer and turning the slow wave motion into high pressure and rotational speed for optimum generator output. Any potential damaging load is caught in the hydraulic system with pressure control valves for safety, lowering the risks of anchored devices and the need for extremely strong connections as this is a form of active mooring. Unlike most of its competitors, the Slow Mill is engineered to let big waves pass overhead. When the wave force is greater than the upward capacity, the floater submerges a bit and lets the wave partially roll over while continuing to generate full power. Due to the smart construction and constant tension on the connection to the anchor, snap loads are avoided, further decreasing wear, tear and fatigue while contributing to a long and save life at sea.
