UK The first of eleven turbines has been installed at the innovative test and development wind farm off the Scottish shore.

Vattenfall’s European Offshore Wind Deployment Centre (EOWDC) is a test and development centre located in Aberdeen Bay, in North-east Scotland. On Monday, 9 April, the first 8.8 megawatt turbine from MHI Vestas was deployed, making it the world’s most powerful commercially installed wind turbine.

“The first turbine installation is a significant achievement and credit to the diligence and engineering know-how of the project team and contractors. We are very excited by the cutting-edge technology deployed on all the turbines and it is remarkable that just one rotation of the blades can power the average UK home for a day,” says Vattenfall’s project director Adam Ezzamel.

Less noise with giant buckets
The EOWDC wind farm features several ground-breaking innovations for offshore wind industry. Notably it uses suction bucket jacket foundations for the turbines instead of piling the foundations in to the sea bed, which is the normal procedure. The suction bucket method is virtually noiseless which minimises the disturbance on sea wildlife.

When water is pumped out of the suction buckets, they sink in to the sea bed sediment. For decommissioning, water is pumped back in to retrieve the entire structure.  

The EOWDC wind farm will consist of 11 turbines with a total output of 93.2 megawatt. The annual production is the equivalent of 70 percent of Aberdeen’s electricity demand.

Gunnar Groebler, Vattenfall’s Head of Business Area Wind, said: “The EOWDC, through its innovative approach to cost reduction and pioneering technologies, leads the industry drive towards generating clean and competitive wind energy power and help secure Vattenfall’s vision to be fossil fuel free within one generation”
