Van Oord has installed the final jacket foundation for the East Anglia One offshore windfarm in the UK
It also transported and installed all 102 foundations for the project, making this the largest number of three-legged jacket-type foundations installed on any offshore project.
Due to be completed in 2020, East Anglia One is expected to supply the equivalent of more than 630,000 British households with green electricity.
Van Oord said most of the installation work took place in water depths of more than 40 m in the North Sea at a location where conditions are challenging, currents are strong and underwater visibility minimal.
The company developed a pile-driving template to install the foundations in these conditions. The Van Oord team used the template to drive the piles for each of the jacket foundations into the seabed.
The first turbine blade for the 714-MW East Anglia One offshore windfarm was completed in February 2019.
The blade was manufactured by Siemens Gamesa at its factory at Green Port Hull and is the first of 306 to be manufactured at the site.
The £2.5Bn (US$3.2Bn) East Anglia One project will see 102 Siemens Gamesa turbines installed, each with a capacity of 7 MW.
