World's most powerful commercial wind turbine successfully installed

11.04.2018

A hat-trick of offshore wind industry firsts has been achieved within a fortnight in North-east Scotland after the world’s most powerful single turbine was successfully installed on April 9th for Vattenfall’s European Offshore Wind Deployment Centre (EOWDC). The turbine is the first of 11 to be deployed at the facility in Aberdeen Bay. Two turbines will have a capacity of 8.8 MW, the other nine will have a capacity of 8.4 MW

The Output of EOWDC will be at 93.2 MW. This allows the facility to produce the equivalent of more than 70% of Aberdeen’s domestic electricity demand.

Monday’s feat of engineering comes less than two weeks after the first of the EOWDC’s game-changing suction bucket jacket foundations was successfully installed. The EOWDC is the first offshore wind project to deploy the foundations at commercial scale and 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 80m long - slightly taller than Aberdeen’s Marischal College – and the 164m rotor has a circumference larger than that of the London Eye’s.

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 8.8MW 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 average 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 (AREG), 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.”

Slowly but surely the floating offshore wind energy sector is becoming more and more important, particularly because of the fact that the number of locations with shallow waters suitable for fixed-bottom foundations is limited. Floating wind is turning into a highly scalable future energy source because the wind resource in deep waters is extensive and offers a significant potential for marine renewable energy development and growth to many countries.

Developers commissioned a little over 45GW of onshore wind turbines globally in 2018 compared with 47GW a year earlier. Just four manufacturers accounted for more than half, or 57%, of the machines deployed: Denmark’s Vestas, China’s Goldwind, GE Renewable Energy of the U.S. and Spain’s Siemens Gamesa.
