    FREDERICIA, Denmark – Ørsted has issued an update on what it claims will be the world’s largest offshore wind farm.

    Heerema’s crane vessel Sleipnir has installed the 8,000-metric ton offshore substation (OSS) at Hornsea Two in the UK North Sea. Ørsted claimed this is the world’s largest AC OSS.

    The reactive compensation station is expected to be installed soon.

    DEME’s jackup vessel Innovation has installed all 165 wind turbine foundations. Its jackup vessels Sea Installer and Sea Challenger are installing the 165 Siemens Gamesa 8-MW turbines. According to Ørsted, two-thirds of the wind turbines have been installed.

    Located 89 km (55 mi) off the Yorkshire coast, Hornsea Two will be Ørsted’s 13th offshore wind farm in the UK. Once it is operational in 2022, the 1.4-GW offshore wind farm is expected to provide power to more than 1.3 million homes in the UK.
