Ocean wave power generation systems - Ocean wave power generation systems capture kinetic and potential energy from sea waves to produce electricity. These systems use mechanical or hydraulic converters and are increasingly seen as reliable, predictable alternatives to wind and solar energy.

Ocean wave power generation systems are comprehensive setups designed to harvest the energy from surface ocean waves and convert it into electrical current that is delivered to a customer or the main grid. These systems comprise three essential functional components. Firstly, the wave energy collector, which is the primary structure that interacts with the waves (e.g., a buoy, a hinged raft, or a fixed column) to capture their energy.

Secondly, the power take-off (PTO) system, which is the internal machinery that transforms the chaotic, low-speed, high-force mechanical energy of the collector's motion into regular, high-speed rotary or linear motion suitable for a generator. 

Thirdly, the mooring and transmission infrastructure, which includes robust anchors, dynamic subsea cables capable of handling movement, and a static export cable that runs from the array to the shore connection point. The efficacy of an ocean wave power system is judged by its ability to survive storm events, operate reliably for long periods without intervention, and maximize energy capture across a wide spectrum of wave conditions. Successful deployment requires detailed site assessment, advanced marine engineering to manage hydrostatic loads, and regulatory approval for both marine navigation and subsea cabling routes.
