Fukushima Forward

The first Mitsubishi 7MW wind-turbine with a Digital Displacement® transmission (DDT) is currently on test at the Hunterston test-site near Glasgow – a land-based facility that has been created to test prototypes of wind-turbines that are intended to operate offshore.

The second 7 MW Mitsubishi DDT machine is destined to operate as a floating wind-turbine in deep water 20km off Fukushima in Japan. The turbine has now been assembled at the port of Onahama and mounted onto a three-column semi-submersible floating structure.

UnknownThis will be the largest wind-turbine of any kind in Japan and the largest floating wind-turbine in the world.

A 2MW turbine is already operating at the Fukushima offshore site. Both projects have been instigated by the Fukushima Wind Offshore Consortium, which comprises trading house Marubeni,  Mitsubishi Heavy Industries, Hitachi and the University of Tokyo.

For both of the 7MW wind-turbines, Artemis supplied all of the computer-controlled low-pressure valves, manufactured the associated electronics and wrote the software for the control of the Digital Displacement® transmission.

Nikkei Asian Review have published a comprehensive account of the Fukushima project and a GettyImages website shows more images of the Fukushima wind-turbine.

The upper photo shows one of the electronics and control cabinets for the Fukushima wind-turbine on test at Artemis. The lower photo, taken at the port of Onahama by an Artemis engineer who is based in Japan, shows the Fukushima turbine mounted onto one of the three buoyant legs of the floating platform.
