NOVELTY - The plant comprises in-line arrays (1-10) of SWEC sub modules (11) self-adjusted for tide levels. The sub modules utilizes dual-action piston pumps, provided with a common solid shaft, which capture energy not only during rise of the waves to the peak but also during fall of the waves to the trough. Logically controlled hydraulic systems enable intelligent collection of hydraulic outputs of such arrays. Each sub module also incorporate cylindrical floats and ballasts. An automatic level control adapts system height to tide level and submerges for self-preservation during weather events.    USE - Sea wave energy plant for producing electrical energy for grid consumption from ocean waves. Can also be used for delivering seawater under significant pressure for use in desalination systems.    ADVANTAGE - The plant includes SWEC sub-modules employing dual-action piston pumps for capturing energy during rise and fall of waves, and logically controlled hydraulic systems to collect hydraulic outputs of arrays of such sub-modules, reducing pulsation associated with wave power, while allowing the plant to accept waves from any direction without adjusting the system or float layout. The cylindrical floats are made from existing pontoon or float products, ensuring cost effective production. The cylindrical shape of each float enables capture of energy of waves from any direction without need for alignment. The height of each float in the float and ballast combination can be set to maximum of half of that of available wave height at desired location to efficiently capture maximum energy from the waves rise to the peak. The effective ballast weight is half of the effective float value to equally power the down stroke in the fall of the waves to the trough. The float, ballast and any related structure can be made from standard plastic pipes, which have high resistance to seawater and can be produced, procured and replaced in affordable manner. The use of hydraulic accumulators also enables reduction in pulsation.    DESCRIPTION OF DRAWING(S) - The drawing shows the perspective view of a power plant.
