The final turbines have been installed at the Walney Extension offshore wind farm.
The project off the coast of Cumbria features 87 turbines with a total capacity of 659MW, making it the world’s largest offshore wind farm. The record was previously held by the 630MW London Array wind farm.
Turbines from two different manufacturers were used for the project.
MHI Vestas supplied 40 of its 8MW V164 turbines, which were upgraded to deliver a maximum power output of 8.25MW.
Siemens Gamesa provided 47 of its 7MW SWT154 turbines. The Walney Extension is the first wind farm in the world to use the new model.
The project is jointly owned by Orsted (50 per cent) and the Danish pension funds PFA (25 per cent) and PKA (25 per cent).
Walney Extension programme director at Orsted, Andrew Cotterell, said: “We’re delighted to announce that all 87 turbines have been installed. It’s thanks to the hard work of all the teams involved, both within Orsted and our partner contractors, that we have successfully reached this significant milestone on schedule.
“We are now focussed on completing construction and looking forward to seeing the world’s largest wind farm brought safely into commercial operation later this year.”
The wind farm is expected to become operational in the second half of 2018.
