A Japanese consortium has unveiled a 7MW oil pressure drive-type wind turbine for the experimental Fukushima floating offshore wind project following the completion of its assembly works.

The project is being sponsored by Japan’s Ministry of Economy, Trade and Industry.

Mitsubishi, Mitsubishi Heavy Industries, the University of Tokyo, Marubeni, Japan Marine United, Mitsui Engineering & Shipbuilding, Nippon Steel & Sumitomo Metal, Hitachi, Furukawa Electric, Shimizu, and Mizuho Information & Research have formed a consortium to work on the project since March 2012.

Turbine installation for the project was performed at Onahama port on a three column semi-sub floater, which will be moved to the testing area soon.

The 7MW oil pressure drive-type wind turbine is the largest of its kind in the world.

The second term under this phase of the construction has been outlined by Mitisbushi, which will involve assembling of 5MW downwind-type floating wind turbine and its connection to the undersea cable.

"The 7MW oil pressure drive-type wind turbine is the largest of its kind in the world."

The consortium is already working on the 5MW turbine, with its chains and anchors having been procured and production of its high-voltage riser cable completed.

Mitsubishi and partners expect to complete delivery of the facility from Onahama and its mooring operation in the testing area by the end of this month.

Electric work and commissioning for the 7MW turbine have been scheduled to be completed by mid-September. A demonstration operation for the turbine is likely to start in mid-December.

The project involves installation of three floating wind turbines and one floating power substation off the coast of Fukushima in Japan.

The first phase of the project involved installation of a 2MW floating wind turbine installation along with a 25MVA floating substation and undersea cables.

This second phase will include addition of these two 7MW and 5MW wind turbines.
