A plant, generator and rotating member for the production of power from currents in a body of water, comprising a fixedly mounted of floating structure, and a plurality of replaceable generator units ( 750 ) supported by the structure and which are driven by the water currents. The structure comprises arms ( 615, 720, 730 ). The rotating member ( 400 ) comprises a plurality of member sections ( 410 ) rotatably mounted on a shaft ( 405 ) between an end piece ( 407 ) and a tip ( 406 ). The generator comprises a contra-rotating rotor ( 550 ) and stator ( 800 ) connected to respective shafts ( 500, 820 ) and hearings, where the stator frame ( 800 ) is axially supported ( 810 ) on the first shaft ( 500 ) and the first shaft ( 500 ) at one end thereof is axially supported ( 810 ) on the stator frame. The generator according to the invention can be used for the production of electric power, and as an electromotor for the production of mechanical rotational energy.
