The £2.5bn project will feature 102 Siemens-built wind turbines to generate electricity required to power over 500,000 average UK households.
Under the contract, Navantia will fabricate 34 jackets at its shipyard in Fene, Spain while Windar will build the jacket piles at its facilities in Avilés, Spain.
Said to be one of the largest of its kind, the wind farm is planned to be fully-operational by 2020.
Located approximately 43km off the Suffolk Coast in the southern North Sea, the East Anglia One project is scheduled to be commissioned in 2020.
Navantia chairman José Manuel Revuelta said: “This contract consolidates Navantia as a key player in the offshore wind industry and highlights the company's aspiration to expand its participation in East Anglia One by increasing the number of jackets to be built in Fene and winning the offshore substation tender process.”
The contract is expected to enable Navantia and Windar to maintain jobs at their respective facilities, providing nearly 850,000 man-hours between March 2017 and June 2018.
Iberdrola is seeking consent to build 1,200MW East Anglia Three wind farm, which if approved would bring the total capacity at East Anglia could to 2,000MW.
The project is expected to contribute to the UK’s goal to reduce greenhouse gas emissions by 34% by 2020 and at least 80% by 2050 as part of its Climate Change Act 2008.
