The first suction bucket jacket foundation has been installed for Vattenfall’s European Offshore Wind Deployment Centre (EOWDC) in Aberdeen Bay.
The successful installation of the first suction bucket jacket foundation for the 11-turbine EOWDC took place this weekend - a UK offshore wind first.
Using the 25,000tn Asian Hercules III floating crane which arrived earlier this year, the 77m tall, 1,800tn steel jacket foundation was installed in just 15 hours at the £300M project.
It is believed that EOWDC is the first offshore wind project to deploy the foundations at commercial scale, with each of the 11 steel jacket foundations installed without noise or vibration.

Vattenfall’s EOWDC project director Adam Ezzamel said: “The first installation of the suction bucket foundations is a major accomplishment for the EOWDC project team, our contractors and the offshore wind industry. Suction bucket jacket foundations - which can each be installed with a single offshore lift, virtually without noise and within a matter of hours - bring considerable environmental benefits. They are lowered into the water where the upturned buckets are rapidly embedded into the seabed to create a secure foundation for installation of the world’s most powerful wind turbine later this spring.
“By enabling faster and smarter installation, the technology will drive down offshore wind costs considerably, provide a further foundation option at challenging sites, whilst also allowing an easier and complete decommissioning. These foundations are the first visible structures offshore for the EOWDC which we hope will go some way to help establish the North-east as a centre for offshore wind innovation.”

Jean Morrison, chair of Aberdeen Renewable Energy Group (AREG) added: “The EOWDC has always intended to be a pioneering development and the use of the suction bucket jacket foundations is a great example of fresh innovation in the offshore wind sector. This is another exciting stage for the project with first visibility of the structures offshore as the project moves closer to its operational phase.”

When completed the 92.4MW EOWDC will be Scotland’s largest offshore test and demonstration facility. It will trial next generation technology will generate the equivalent of 70% of Aberdeen’s domestic electricity demand and annually displace 132,977 tonnes of CO2. Each turbine will be capable of powering about 7500 homes a day.
Fugro completed the ground investigation work for the project in April 2016.
