SSE Renewables and TotalEnergies have installed over 50 jacket foundations at the 1100MW Seagreen offshore wind farm off east Scotland.
The three-legged jacket foundations, each weighing around 2000 tonnes, will play a critical role in safely supporting the wind turbines during Seagreen’s 25-year operational lifespan.
Situated around 27 km off the Angus coast, the £3bn wind farm is a joint venture between SSE Renewables (49%) and TotalEnergies (51%).
When complete, Seagreen will consist of 114 Vestas V164-10.0 MW turbines, the first of which started generating power to the UK national grid recently.
SSE Renewables is leading the development and construction of the Seagreen project and will operate Seagreen on completion for its expected 25-year lifetime.
Installation of the foundations is being carried out by Aberdeen-based Seaway 7.
John Hill, Seagreen’s Project Director, said: “Seeing the jacket installation process reach the halfway point demonstrates successful innovation with the largest ever deployment of foundations using suction caissons in offshore wind.
“Reaching this milestone is a testament to the hard work and determination of everyone involved in the construction of Scotland’s largest and the world’s deepest fixed bottom offshore wind farm.”
The overall turbine foundations installation campaign is supporting over 140 skilled jobs at Port of Nigg.
