Seagreen reaches another milestone with offshore substation topside installed
Our team supporting the construction of the world’s deepest fixed bottom offshore wind farm, which is also Scotland’s largest, has reached an important milestone with the installation of the offshore substation topside in the North Sea.
The substation forms the backbone of the offshore wind farm. At 40 metres long, 45 metres wide and 15 metres high, the 4,800 tonnes heavyweight topside superstructure accommodates three circuits to generate 1075 MW of electricity.
Vipul Sawe, Petrofac’s Senior Project Director said:
“The safe and successful installation of the substation topside is a significant milestone in the delivery of this important energy transition project for the UK. Everyone involved should be proud of this achievement and the great teamwork and collaboration shown between all partners and parties working together.”
Situated around 27 kilometres off the Angus coast, the Seagreen wind farm is a joint venture between SSE Renewables (49%) and TotalEnergies (51%). At 1.1GW, the wind farm will be capable of generating around 5,000 GWh of renewable energy annually which is enough clean and sustainable electricity to power more than 1.6m UK homes. With the equivalent saving of around two million tonnes of carbon dioxide emissions annually, Seagreen will make a significant contribution to Scotland’s and the UK’s net zero targets.
We are providing the engineering, procurement, fabrication, transportation, offshore installation and commissioning of the High Voltage Alternating Current (HVAC) offshore substation platform. In addition to the topside, this includes the jacket that supports the offshore platform substation, which was successfully installed and secured on the seabed earlier this year. An onshore substation scope with all civil work and major equipment is also included.
