Scotland’s Largest Offshore Wind Farm Entering Home Stretch

75 per cent of the jacket foundations have been installed at the Seagreen offshore wind farm, according to the latest social media update by one of the project’s developers, SSE Renewables.

So far, there are 89 jacket foundations and 74 wind turbines installed at the project’s construction site.

The three-legged jacket foundations, each weighing around 2,000 tonnes, are being placed in depths up to 58 metres off the Angus coast.

Besides being the largest Scottish wind farm, Seagreen is also the world’s deepest project of this kind using bottom-fixed foundations.

Installation of the foundations is being carried out by Aberdeen-based Seaway 7 with the first jacket installed in October last year.

The GBP 3 billion (approx. EUR 3.6 billion) project, located 27 kilometres off the coast of Angus in Scotland, will comprise 114 Vestas 10 MW turbines, all of which are expected to be operational in the first half of 2023.

The wind turbines are being transported from Vestas’ turbine marshalling base at Able Seaton Port in Hartlepool and installed at the site by Cadeler’s wind farm installation vessel, Wind Orca.

A couple of months ago, the wind farms’ developers, SSE Renewables and TotalEnergies, received a go-ahead from the Scottish Ministers to increase the combined capacity of the Seagreen offshore wind farm from 360 MW to 500 MW, bringing the project’s total installed capacity to 1,575 MW.
