The final turbine has been installed at a new offshore wind farm in north Norfolk.
All 91 turbines are now in place at the Race Bank wind farm, keeping the project on schedule to be fully operational in early 2018.
The wind farm is being built by Ørsted (formerly Dong Energy).
David Summers, project director for Race Bank at Ørsted, was delighted at the successful installation.
He said: 'This has been one of the more difficult projects to execute with challenging seabed conditions and a complex export cable route. Construction has progressed well and we're right on schedule – this is an important milestone to reach.
'We're looking forward to completing construction and seeing a fully operational wind farm next year that will be capable of powering over half a million UK homes.'
Many of the wind farm's 6MW Siemens turbines feature the first blades to be manufactured at the Siemens blade factory in Hull.
