Orsted has installed the final Siemens Gamesa 6.3MW turbine at its 573MW Race Bank wind farm off the Norfolk coast of the UK.
Commissioning work at the project is ongoing, with the wind farm expected to be fully operational in early 2018.
“This has been one of the more difficult projects to execute with challenging seabed conditions and a complex export cable route,” said Race Bank project director David Summers.
The project is the first to feature blades made at Siemens Gamesa's £310m factory at Hull's Alexandra Dock.
Approximately half of of the blades to feature at the project were made on Humberside and Siemens Gamesa Renewable Energy managing director Clarke MacFarlane said the locally-made kit marked “a turning point” for the UK renewable energy industry
A2Sea jack-up Sea Installer started installing the project's 91 turbines in May and will now return to the Danish port of Esbjerg for demobilisation.
