ABERDEEN, UK – Petrofac’s team supporting the Seagreen wind farm in the North Sea, 27 km (16.8 mi) from Angus, eastern Scotland, has installed the topsides for the offshore substation.
According to the company, this will be the world’s deepest fixed-bottom offshore wind farm.
The substation is 40 m (131 ft) long, 45 m (147.6 ft) wide and 15 m (49.2 ft) high. Its 4,800-metric ton (5,291-ton) topside superstructure accommodates three circuits to generate 1,075 MW of electricity.
Seagreen is a joint venture between SSE Renewables (49%) and TotalEnergies (51%). It will eventually produce sufficient electricity to power more than 1.6 million homes.
Petrofac is responsible for engineering, procurement, fabrication, transportation, offshore installation and commissioning of the HVAC offshore substation platform.
The jacket was installed earlier this year. The scope of work includes an onshore substation scope with associated civil work and major equipment.
