Development and Demonstration Test for Floating Type Ocean Current Turbine System Conducted in Kuroshio Current

Ocean current known as Kuroshio Current flows in the vicinity of Japanese coastal area is the one of strongest ocean current all over the world. In order to realize power generation utilizing the Kuroshio ocean current, IHI has been developing the floating type ocean current turbine system. In this study, we have carried out technical development of the floating type ocean current turbine system, engineering, and construction of design rated output 100kW turbine demonstration prototype named `Kairyu' in IHI. With using this Kairyu, the world first demonstration test in Kuroshio Current area located off Kuchinoshima Island of Kagoshima prefecture was conducted and completed on August-2017. As a result, we achieved installation procedure feasibility, submergence height and attitude stability in operating condition with control, and power generation output, and so on.
