50 out of the 114 Vestas V164-10.0 MW turbines have been installed at the 1.1 GW Seagreen offshore wind farm, Scotland’s largest and the world’s deepest fixed-bottom offshore wind farm.
(OW) 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.
Wind Orca, which replaced her sister vessel Wind Osprey on the project, is assisted during the installation by the service operation vessel Acta Centaurus, and the crew transfer vessels, HST Harri and HST Euan.
The first wind turbine was installed at the site some 27 kilometres off the Angus coast in early December. This marked the first time a wind turbine with a double-digit megawatt capacity was installed offshore Europe.
Seagreen delivered first power to the Scottish grid in late August.
The turbine installation programme is running in parallel with the ongoing foundation installation campaign, which is being run by Seaway 7 out of Scotland’s Port of Nigg.
The project’s latest Notice of Operations (NOO) shows that 62 wind turbine jacket foundations have been installed at the site so far. A jacket foundation designated for the deepest location within the project site is planned to be installed at 59 metres below sea level in December.
The GBP 3 billion project, owned by SSE Renewables and TotalEnergies, is expected to be fully operational in the first half of 2023.
SSE Renewables (49 per cent) is leading the development and construction of the Seagreen project on behalf of the partnership with TotalEnergies (51 per cent) and will operate Seagreen on completion for its expected 25-year lifetime.
Once operational next year, the 1.1 GW wind farm will be capable of generating around 5,000 GWh of renewable energy annually which is enough electricity to power more than 1.6 million UK homes.
