The world’s largest floating offshore wind development will be installed off the coast of Scotland after the application has been granted a marine licence by the Scottish Government. 

Statoil propose developing a pilot park of five floating 6 MW turbines-  with a generating capacity of 135GWh of electricity each year – about 15 miles offshore from Peterhead. It is expected that the Hywind Scotland development could power up to 19,900 houses. 

Unlike conventional turbines, Hywind turbines will be attached to the seabed by a three-point mooring spread and anchoring system. 

The turbines will be connected by an inter-array of cables and an export cable will transport electricity from the pilot park to shore at Peterhead. 

The Carbon Trust believes that floating wind concepts have the potential to reduce generating costs to below £100/MWh in commercial deployments, with the leading concepts such as Hywind, with even lower costs of £85-£95MWh. 

John Swinney, Scotland’s Deputy First Minister, said: “Hywind is a hugely exciting project – in terms of electricity generation and technology innovation – and it’s a real testament to our energy sector expertise and skilled workforce that Statoil chose Scotland for the world’s largest floating wind farm. 

“The momentum is building around the potential for floating offshore wind technology to unlock deeper water sites. The ability to leverage existing infrastructure and supply chain capabilities from the offshore oil and gas industry create the ideal conditions to position Scotland as a world leader in floating wind technology.” 

Irene Rummelhoff, Statoil executive vice-president for New Energy, said: added: “Floating wind represents a new, significant and increasingly competitive renewable energy source.

“We are proud to develop this unique project in Scotland, in a region that has optimal wind conditions, a strong supply chain within oil and gas and supportive public policies.”

“Statoil’s objective with developing this pilot park is to demonstrate a commercial, utility-scale floating wind solution, to further increase the global market potential.”
