The world’s most powerful single offshore wind turbine has been installed by Vattenfall in waters off the coast of Scotland.

The turbine is the first of 11 to be deployed at the European Offshore Wind Deployment Centre (EOWDC) in Aberdeen Bay.

The turbine is one of two that have been significantly enhanced with further internal power modes which have increased output from 8.4 MW to 8.8 MW – the first time an 8.8 MW model has been deployed commercially in the offshore wind industry.EOWDC project director Adam Ezzamel

Together with the nine 8.4 MW turbines, this substantially boosts the EOWDC’s output to 93.2 MW and allows the facility to produce the equivalent of more than 70 per cent of Aberdeen’s domestic electricity demand.

The installation of the turbine this week comes less than two weeks after the first of the EOWDC’s suction bucket jacket foundations was successfully installed. The EOWDC is the first offshore wind project to deploy the foundations at commercial scale and Vattanfall said that pairing them with the world’s most powerful turbines represents another industry first.

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.”

MHI Vestas has specially designed the V164-8.4 MW and V164-8.8 MW turbines which all have a tip height of 191 metres. Each blade is 80 metres long and the 164 metre rotor has a circumference larger than that of the London Eye.

EOWDC project director at Vattenfall, Adam Ezzamel, said: “The first turbine installation is a significant achievement and credit to the diligence and engineering know-how of the project team and contractors. For it to be one of the 8.8 MW models makes it an even more momentous moment because it further endorses the EOWDC as a world-class hub of offshore wind innovation.

“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 averagWorld’s most powerful offshore wind turbine is installede UK home for a day.”

MHI Vestas chief operations officer, Flemming Ougaard, said, “We are very pleased to have installed the first of 11 turbines at Aberdeen Bay. Our collaboration with Vattenfall not only provides clean wind energy for the UK, but also is an important opportunity for us to gain valuable experience with several different technologies. We look forward to the successful installation of the remaining turbines.”

 

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.

Jean Morrison, chair of Aberdeen Renewable Energy Group, said: “The EOWDC is leading the way in terms of innovation for the offshore wind sector and will help enable the next generation of offshore wind. It’s a real coup for the region to have the world’s most powerful turbines on its doorstep and cements Aberdeen’s position as a major global energy city. It also will lead us to a greener future.”
