Description: 

Demonstration Research of Ocean Energy Power Generation (Ocean Current Generator in the Sea (Subsea floating Type)

 

A consortium of IHI Corporation, Toshiba Corporation, the University of Tokyo, and Mitsui Global Strategic Studies Institute is developing a floating type oceanic current turbine system. The fundamental research and development were launched at 2011, and the field demonstration was planned from 2014.The floating type oceanic current turbine system consists of two turbines (0.05 MW x 2 with the turbine diameter of 11 m) which rotate in different directions so that the rotary torque generated by turbine rotation is cancelled. The turbine system is moored from the anchor installed on the sea bottom, and is suspended at underwater in operation. The depth of the sea is around 100 m, and the turbine system is installed at 30-50 m below sea surface. It can be floated up to the sea surface for maintenance.

Power Generation Using the Kuroshio Current provides some additional information.

Location: 

Kuroshio Current in Ocean, 100 m in depth, Kuchinoshima (Island), Toshima Village, Kagoshima Prefecture. Water current velocity will be 1.5 m/s.

Process Status: 

Towing test of the turbine was carried out in July 2017. Turbines were moored for 1 week in August 2017.

IHI Ocean Current Turbine is located in Japan.
