oscillating bodies
oscillating bodies are the more diverse group of WECs. this group brings together all of those conversion devices that harness the wave energy through a body usually a floater or a buoy, which is forced to maintain an oscillatory movement i.e., a heave roll or pitch motion. oscillating bodies are either floating or bottom fixed devices designed to exploit the more powerful deep water wave regimes. in general they are more complex than OWCs, in particular as regards the power take off (PTO) systems. in fact the many different concepts and methods to transform the oscillating movement into electricity have given rise to many different PTO systems, e.g., hydraulic generators with linear hydraulic actuators, linear electric generators, piston pumps, etc
