Aker to develop Scotland’s first offshore wind underwater substation

2021-10-12 Aker Offshore Wind

Aker Offshore Wind has outlined plans to utilise Scotland’s first offshore wind underwater substation as part of its bids for major offshore windfarms.

The multi-million subsea innovation would be developed, manufactured, and supplied in Scotland by Aker Solutions and provide major export opportunities for Scottish businesses.

Substations – which help move the energy created by wind turbines into homes and businesses – are traditionally installed above sea level but moving them down to the seabed brings several reliability and cost benefits. For example, the seawater can be used as a natural cooling system, while reliability is increased through stable temperatures, fewer components and no rotating parts. In addition, operational costs can decrease by less maintenance and reduced material use. 

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 could deliver up to 6,000MW of energy in the Outer Moray Firth. It would be by far the UK’s biggest wind energy development and power millions of homes with renewable energy.

Aker Offshore Wind’s heritage and experience working in the North Sea with subsea technology means it would create jobs, economic opportunity and deliver major environmental benefits. Aker Solutions, a sister company of Aker Offshore Wind and a key supplier to UK wind projects, is a frontrunner in developing subsea substations and related power system designs. The company would support the delivery of substations from its Aberdeen facilities.
