Wave energy conversion

摘要: Apparatus (10) for harnessing ocean wave energy in a body of water (11) which the apparatus incorporates provision relieving excessive loadings on components conversion system purpose avoiding damage thereof adverse conditions. The includes buoyant actuator (14) and pump (15) anchored within water, typically seabed 13. is operable closed-loop mode wherein fluid at high pressure pumped ashore by (15), extracted as useful work an on-shore plant (17), resultant reduced returned to offshore be re-energised. operably connected tether (19) buoyantly suspended above (15). provided with connection means (61) adapted provide yieldingly resilient between hollow (21) (19). means( 6)1 comprises damping (63) configured maintain substantially rigid until such time loading therebetween exceeds prescribed load whereupon facilitates limited relative movement relieve loading. Additionally, or alternatively, controlling operation dissipation purposes response condition.
