JAPAN: The Marubeni-led consortium working on the Fukushima offshore wind farm demonstration project has announced that construction of the three-column semi-sub floating platform supporting the 7MW turbine has been completed.

The consortium also announced that construction of the 7MW Mitsubishi SeaAngel, using a hydraulic drivetrain, is in progress at Mitsubishi Heavy’s Yokohama Dockyard and Machinery Works.

Undersea cables are in production at the Chiba Works of Furukawa Electric, and preparation is under way to connect the cables to the 66kV floating power sub station.

The chains are expected to be laid along with the anchors by late August, with a similar timing seen for the shipping, laying and burying of the undersea cable.

Work on mounting the turbine on the three-column semi-sub floater at Onahama Port in Fukushima prefecture is expected to take place from early December. The mounting of the turbines is seen as vital to the second stage of the project.

The SeaAngel turbine is outside the scope of the MHI Vestas joint venture, which is focused on the 8MW V164 turbine, although the SeaAngel's drivetrain could be transferred to the V164 at some stage.
