The disclosed floating power plant is an ocean (10) placed flotation cylinder shaft (1) having a turbine and inlet cones section (2) affixed so as to let a fluid column (3) move up and down through the turbine (2). The fluid column (3) is forcefully driven through the turbine (2) by two piston sections (4 & 5) connected by piston rods (6). The piston sections (4 & 5) are kept near stationary by the pressure plate (7) and alternately compresses the fluid (3) against either side of the turbine (2) as the floatation cylinder shaft (1) moves up and down with the changing ocean wave surface (8) through buoyancy of the flotation chambers (11). Suspension (9) helps pull the turbine (2) in the downward direction. During high-pressure compression fluid (3) is bled off to a high-pressure hydraulic system (16). Low-pressure fluid is returned again during the low-pressure cycle (17). The upper piston section (4) is open to the vent (12) and can be vented to the open air. Rotation of the turbine (2) is transferred through the axle (13) to the gearbox and generator room (14). The power plant is kept in position by hydraulic control jets (15).
