NOVELTY - The turbine (1) has flap units (4) rotatably or movably attached to the turbine such that position of the flap unit is individually adjustable between closed position and open position in response to pressure in water around the flap unit and independently of tabs. The flap units are arranged wholly or partially outside each other in a radial extent of a flap turbine's rotation axis. Turbine arms (7) are provided with respective pendulum arms on-which the flap units are rotatably or movably mounted on the pendulum arms.    USE - Flap turbine for use in a power plant (claimed) i.e. submerged power plant, for converting kinetic ocean energy from ocean waves, tides and currents.    ADVANTAGE - The turbine increases energy levels inside the plant for all three forms of kinetic ocean energy and exploits kinetic ocean energy from surrounding areas. The turbine accelerates seamass and prolongs power component of motion. The turbine is designed with better energy production during periods of low incidence in an efficient manner. The turbine maintains the kinetic ocean energy movement cycles under sustained and incremental energy conversion and increases overall efficiency. The turbine reduces utilization under dangerously large ocean waves and reduces energy loss when transferring ultimately energy. The turbine prevents unwanted reflection of energy from sea waves through incremental energy conversion, secures stable electricity production regardless of fluctuating energy rates and ensures operational and maintenance conditions. The turbine reduces and eliminates a need for sea cabling.
