Van Oord installs first jacket foundation on East Anglian wind farm

Van Oord has finished installing the first jacket foundation on the off shore East Anglia One project.

Scottish Power Renewables commissioned Van Oord as lead contractor responsible for transport and installation of the offshore wind turbine foundations, including logistics and deployment of the equipment.

The wind farm’s 102 three-legged jacket foundations will be installed at depths of 55m in the southern North Sea.

East Anglia One will have the largest number of three-legged foundations ever installed in a wind farm.

Van Oord project director Daan Makkink said: “This project makes our expertise in the installation of foundations even broader. So far only a handful of wind farms have been constructed on jacket foundations. Their number will increase in the years ahead because the ideal locations for wind farms built on monopiles – shallow waters with a relatively flat, firm seabed – are filling up fast.”

The jackets, along with piles for the scheme, were fabricated by Lamprell at yards in Jebel Ali, Hamriyah and Sharjah.

The offshore wind farm is located 45km southeast of the town of Lowestoft. Its 102 Siemens 7MW wind turbines will ultimately deliver a total of 714 MW.

Work on shore has also started with construction of a substation at Bramford in Suffolk. The scheme will nclude 37km of horizontal directional drilling work from 20 locations in order to connect the new wind farm via underground tunnels rather than overhead cables.

Once the wind farm becomes operational in 2020, it will supply green energy to 500,000 households.
