Twin rotors bring 15MW offshore turbine closer

Twin rotors bring 15MW offshore turbine closer

Eize de Vries talks to the German consultancy's owner and director, Sönke Siegfriedsen, about design, testing and plans for future commercialisation . The striking super-compact drive SCDnezzy2 twin-rotor concept represents a radical vision of what large-scale floating offshore power plants could look like by 2025. It incorporates several prominent innovations, starting with two downwind turbines centre-to-centre, closely interspaced at only one full rotor diameter plus two metres. The two-bladed rotors counter-rotate to balance the opposing Coriolis forces acting upon them. Another distinctive feature is that the relative rotor blade position during operation are offset by 90 degrees, meaning that the blades of one rotor are in a horizontal position when the other is vertical. This aims to minimise the rotor blade interactions that cause tip vortices-related performance l...
