Scotland Breaks Offshore Wind Records with Powerful Turbines and Innovative Foundations

According to Vattenfall, two offshore wind industry firsts have been achieved over the past two weeks in Scotland. On Monday, April 9, the company announced that it successfully installed the world’s most powerful single turbine — an 8.8-MW behemoth standing 191 meters to blade tip and boasting a nacelle that is larger than the London Eye. The turbine is one of 11 that will be installed at the European Offshore Wind Deployment Centre (EOWDC), also known as the Aberdeen Offshore Wind Farm.

Monday’s announcement is just two weeks after the first of EOWDC’s suction bucket jacket foundations was successfully installed, the first time that foundations of this type have been used at commercial scale.

The EOWDC facility is located in Aberdeen Bay. Vattenfall said that the turbine it installed on Monday is one of two MHI Vestas turbines that have enhanced internal power modes so that they generate more wind energy. The two turbines have each increased from 8.4 MW to 8.8 MW.

Together with the nine 8.4-MW turbines, this boosts the EOWDC’s generation capacity to 93.2 MW.

Gunnar Groebler, Vattenfall’s Head of Business Area Wind, said: “The turbines for the EOWDC, Scotland’s largest offshore wind test and demonstration facility, help secure Vattenfall’s vision to be fossil fuel free within one generation. The EOWDC, through its innovative approach to cost reduction and pioneering technologies, leads the industry drive towards generating clean and competitive wind energy power – one that will reinforce Scotland’s global energy status.”

EOWDC project director at Vattenfall, Adam Ezzamel remarked that Vattenfall is excited to be working with the cutting-edge technology deployed at the site.

“It is remarkable that just one rotation of the blades can power the average UK home for a day,” he added.  

The turbines are being transported from Esbjerg to Aberdeen by Swire Blue Ocean’s vessel, the Pacific Orca, where they will be lifted into position on the installed foundations. The Pacific Orca is believed to be the world’s largest wind farm installation vessel.
