DONG Energy senior programme director Duncan Clark said: “Due to the scale of the project, Hornsea Project 1has changed the way we are doing offshore wind projects.

"With EEW SPC we will get the monopiles we need from one supplier that we really can rely on."

In total 91,800 tonnes of steel will be manufactured by EEW SPC for this order from March 2017 through to April 2018. The foundations for the 7MW turbines will have a diameter of up to 8.1 metres.

EEW SPC CEO and managing director Heiko Mützelburg said: "With this prestigious project we are able to achieve another milestone in the development of EEW SPC.

With the completion of the monopiles for Hornsea Project 1 we will have both directly and indirectly produced over 600 foundations for DONG Energy.

Moreover, we are delighted about the renewed confidence in us and are proud that we have been selected to also provide the foundations for the world‘s largest offshore wind farm in the future.”

DONG Energy Structures Procurement director Maria Lindhoff Kjær said: “Based on our long-term collaboration, EEW SPC have proven that they are ready to take on the manufacturing of the full scope of 116 monopile foundations for Hornsea Project 1.”

Due to be operational in 2019, Hornsea Project 1 will be the first offshore wind park which will have a capacity of more than 1 GW.

The wind farm, with 174 wind turbines in total, will be installed off the Yorkshire (UK) coast covering an area of 407 km² and is intended to deliver electricity for well over one million households.
