First Westermost 6MW in the water

Dong and Siemens hailed a landmark in the offshore wind sector today as they revealed the first 6MW turbine has been installed at the UK’s Westermost Rough project.

The turbine is the first of 35 Siemens 6MW machines that will be installed at the site off eastern England.

Westermost Rough is the first commercial deployment of the Siemens turbine, which will eventually be assembled in the UK at the German company’s new plant in Hull.

Duncan Clark, Westermost Rough programme director at Dong Energy said: "This is the first time we have installed the Siemens 6MW turbine with a 154-metre diameter rotor on a commercial scale following smaller demonstration projects, and it represents a step change in our ability to provide more energy output from fewer turbines."

Siemens Wind Power CEO Michael Hannibal added: "Only a few days after our D6 wind turbine obtained its final certification it is in place for commercial operation. We are very proud to achieve this milestone on the way to enhancing efficiency and lowering the cost of offshore wind energy with our innovative direct drive technology."

Turbines are being installed by A2Sea’s Sea Challenger vessel.

The 210MW project is due to be completed and operating next year. It is 50% owned by Dong, with other half split between the UK's Green Investment Bank and Japan's Marubeni.
