AKER Offshore Wind has unveiled plans to utilise its offshore wind underwater substation as part of its bids for major offshore wind farms.
The firm said that the ‘multi-million’ subsea innovation would be developed, manufactured and supplied in Scotland – offering ‘major’ export opportunities for Scottish businesses.
Substations are traditionally installed above sea level, but Aker explained that moving them down to the seabed brings several reliability and cost benefits – such as the seawater being used as a natural cooling system, and increased reliability through stable temperatures, fewer components and no rotating parts.
The project would be delivered as a part of the ScotWind licensing process, for which Aker Offshore Wind has teamed up with Ocean Winds to submit a series of floating bids which it said could deliver up to 6,000MW of energy in the Outer Moray Firth.
The firm added that it would be ‘by far’ the UK biggest wind energy development and power millions of homes with renewable energy.
Sian Lloyd-Rees, MD of Aker Offshore Wind UK, said, “This is a world-leading innovation that would be developed, manufactured and supplied in Scotland. Both the Aker group and Ocean Winds have the necessary heritage and experience to deliver this at scale. We know the benefit is there – it will revolutionise how energy is produced and present Scotland with the opportunity to export genuinely innovative technology to the rest of the world.
“This technology would be supported by tens of millions of investment and work would start next year. It’s a proven technology that we are now using to ramp up the role of renewables in Scotland. Our vision is for the UK to become a global leader in floating offshore wind, contributing to our net zero mission with green energy at scale. Through innovation, we have the opportunity to implement new technology in the ScotWind leasing round, making Scotland and the UK a global leader in subsea solutions for floating offshore wind and exporting the technology around the world.”
“Ocean Winds has worked at the cutting edge of technological innovation to deliver world-leading reductions in the cost of offshore wind energy generation at our Moray East project with innovations from foundation construction to turbine interconnection,” said Dan Finch, managing director of Ocean Winds UK. “The development of subsea substations is another major step forward in terms of using world leading energy technology from our partners, Aker. It will enable construction of windfarms in areas of the seabed which are too deep for fixed substation foundations, therefore facilitating access to cost-effective sites worldwide, even in very deep waters.
“By including this proposal in our Scotwind bid, we can position Scotland at the front of the world’s offshore wind market, with a new, innovative technology, offering the economic opportunities associated with a new product with global demand prospects.
“Our two groups bring together considerable experience of working in the North Sea environment and delivering and operating offshore wind generation, giving us an unrivalled heritage from which to deliver innovation such as this at commercial scale.”
