First jacket foundation installed at Seagreen

Monday, October 11 2021

Wind energy – Seagreen

The first wind turbine jacket foundation has been installed at the 1.1 GW Seagreen, Scotland’s largest and the world’s deepest, fixed bottom offshore wind farm, SSE Renewables said.

Two jackets operated by main contractor Seaway 7 made their way on a barge from Global Energy Group’s Port of Nigg in the Highlands of Scotland to the site 27 kilometres off the coast of Angus, arriving on Wednesday, 6 October.

The barge was met by the Saipem 7000 – the semisubmersible crane vessel which is used to lift each of the 2,000-tonne jackets.

The maiden voyage marked the start of works for the 1.1GW Seagreen Wind Farm project site, a £3bn joint venture between SSE Renewables and TotalEnergies.

The installation campaign marks the first-ever gigawatt-scale deployment of suction caisson technology to fix offshore wind turbine foundations to the seabed.

Several barges will work in continuous rotation with each other carrying two jackets from Nigg to the offshore site before returning to Nigg for replenishment. Each journey from Nigg out to site will take approximately 36 hours depending on the weather.  

More than 50 people are involved each time the barges head out to site including the on-shore team, ballast engineer, tug captain, crew, riggers, welders, tow master and pilot.
