Seawind expects to install the first demonstrator of the two-blded 6.2MW turbine off Norway in 2018

The Seawind design picks up from technology developed by US space agency NASA from the 1980s, abandoned when oil prices fell and superseded by the three-blade designs pioneered in Denmark.  

Launched at the WindEurope and RenewableUK trade show in London (6-8 June), the upwind turbine has a rotor diameter of 126 metres, but, according to CEO Martin Jakubowski, there is ample room to scale up to a rated capacity of 10MW and a 160-metre rotor diameter.

A concrete gravity-based foundation, capable of operating in water depths of up to 50 metres, is part of the package, although floating foundations could be used in later developments.
