A method and arrangement for converting kinetic energy of ocean currents into rotatory energy, using at least one turbine (1) of so-called Savonius type which is arranged to extend substantially vertically from a buoy (2) anchored in such a way in an ocean current that it cannot rotate with the turbine and driving an electric generator (6) or another rotary machine. At the bottom of the turbine (1) a counterweight (8) is provided to retain the turbine (1) substantially vertically at normal speed of the ocean current but to permit it to assume an inclined position when subjected to temporarily increased current speeds, thereby protecting the turbine from harmful flexural stresses and protecting the rotary machine (6) from being overloaded. |
