Hydrocap Energy Seacap
Energy from the waves is absorbed through the vertical movements of a floating buoy that slides up and down a fixed column. The power is transferred via hydraulic jacks to generators, which are situated on a dry deck where the power can be directly used for other activities or exported back to shore via a cable. No critical moving part is situated below the waterline, the buoy itself is made of two half-rings that can be build in a regional shipyard, assembled, towed to location, separated and towed back to land with ease for accidental repair if necessary or periodical inspection. The entire system rests on a column that is fixed to the seabed, typically at depths of 25 to 60meters (plus an allowance for tidal compensation). Survivability is ensured, as the buoy may be disconnected and ballasted to safe depths when necessary then reconnected when operating limits return.
