GeoSea has installed half of the monopile foundations at the Hornsea Project One offshore wind farm in the UK.
The company's jack-up vessel Innovation installed the first of 174 foundations at the site offshore the Yorkshire coast at the beginning of the year.
EEW SPC produced all the monopile foundations for the 1.2GW project, with EEW OSB manufacturing 86, Bladt Industries 68, and Steelwind Nordenham with the Teesside-based Wilton Engineering 20 transition pieces.
Hornsea Project One will comprise 174 Siemens Gamesa 7MW turbines connected to three offshore substations and a reactive compensation substation (RCS).
Ørsted recently signed an agreement to sell 50% of the 1.2GW offshore wind farm to Global Infrastructure Partners (GIP).
The companies plan to have the project fully operational in 2020, when it will become the world's largest offshore wind farm.
