Operating in its element

Bold tern involved in the completion of the worlds’ biggest offshore wind farm

In February 2020, it was one year ago that Bold Tern left the port of Hull in the United Kingdom with the first load of turbines for the world’s largest offshore wind farm installed to date: Hornsea One. Approximately one year later, the wind farm became fully operational.

In September 2019, Fred Olsen Windcarrier’s jack-up installation vessel Bold Tern successfully installed its last turbine on Hornsea One. Bold Tern installed 91 out of the 174 turbines at a distance of 120 km from shore, making Hornsea One the furthest offshore wind farm that has ever been built.

The Bold Tern had been installing turbines in tandem with DEME’s Sea Challenger. Whereas the Sea Installer participated in the transition piece installation campaign. All three vessels are GustoMSC NG-9000C design jack-ups. A fourth jack-up, GMS Endeavour, a GustoMSC NG-2500X design, has been functioning as a modern offshore hotel to support the commissioning activities from an in-field location.

Hornsea One

Hornsea One is an offshore wind farm located off the Yorkshire coast within the Hornsea Zone in the southern North Sea. At 1.2GW, the project will be the world’s biggest offshore wind farm commissioned to date and the first offshore wind farm to have more than 1GW of capacity. The wind farm will have a lifespan of about 25 years and will power approximately one million UK homes.
