Development and Design of a Floating Type Ocean Current Turbine System

Ocean currents are expected as future renewable energy resources. Recently various ideas are studied all over the world to utilize the power of this ocean current for generation of electricity. Application of various types of turbines has been proposed for this purpose, but very little examples have been reported with regard to actual demonstration in the natural ocean current environment.The Kuroshio Current which flows through near Japan coast is one of the strongest ocean currents in the world. To utilize this plentiful energy, we developed the floating type ocean current turbine system “KAIRYU” under the support of NEDO (New Energy and Industrial Technology Development Organization), and we completed the 100 kW order turbine demonstration test in the natural Kuroshio Current.In this paper, we report design methodologies and the results of the test. Especially we focus on the structural design to enable stable flotation in the water, the control of weight distribution and the center of flotation for balance, and the pressure-resistant design of the shell structure to secure water-tightness in the deep sea.
