Description: 

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

 

IHI Corporation is developing a floating type oceanic current turbine system. The fundamental research and development were launched at 2011, and the demonstration was finished in 2017.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. From 2018 to 2020, the oceanic current turbine system will be demonstrated at eight sea areas for more than one year each.

Location: 

The intitial development from 2014-2017 was located in Kuroshio Current in Ocean, 100 m in depth, Kuchinoshima (Island), Toshima Village, Kagoshima Prefecture. Water current velocity was be 1.5 m/s.

 

The upcoming oceanic current turbine system demonstrations will be located off Kamaishi (Iwate Prefecture), Awashimaura Village (Niigata Prefecture), Kabeshima of Karatsu City (Saga Prefecture), Hisakajima of Goto City (Nagasaki Prefecture), Kabashima of Goto City (Nagasaki Prefecture), Enoshima and Hirashima of Seikai City (Nagasaki Prefecture), Kuchinoshima and Nakanoshima of Toshima Village (Kagoshima Prefecture), and Kumejima (Okinawa Prefecture). 

Process Status: 

IHI is preparing the demonstration.

IHI Ocean Current Turbine is located in Japan.
