First field trials of a Digital Displacement® wind-turbine transmission

24th January 2013. Artemis’s parent company Mitsubishi Heavy Industries (MHI) has announced the start of test operations at Yokohama of a ‘large-scale wind power generation system that adopts a hydraulic drive train in place of the earlier gear-driven system’.

Artemis engineers have had the privilege of working with their Japanese colleagues in building this, the biggest yet, Digital Displacement® transmission (DDT®).

The tests, which are taking place within an existing MWT100 wind turbine whose gearbox transmission has been replaced by the DDT®, are the next step in creating a commercial 7 megawatt class offshore wind turbine named SeaAngel.

The first SeaAngel is due to be installed in Scotland during 2013, and two further machines with floating foundations have been ordered by the Japanese government for operation off Fukushima.

Development work on the DDT® for large offshore wind-turbines is supported in the UK by BIS (Department for Business, Innovation and Skills) through the Technology Strategy Board (TSB). Earlier stages of development at Artemis were supported by Carbon Trust and by DECC (Department of Energy and Climate Change).

Mitsubishi work in Japan is supported by the Japanese government through NEDO (New Energy and Industrial Technology Development Organization).
