Hywind Demo � In operation since 2009
Hywind is developed and proven by Statoil.
Qualification programme based upon procedures from Oil and gas industry.

The Hywind project started in 2003
Design, tool development, simulations, model testing.

The full scale demo has been operating since September 2009.
Produced more than 15 GWh Experienced wind vel 36 m/s and Hs 9.06 m Continuous measurements on > 200 channels Extensive database for loads and fatigue data

From Idea to Commercial Concept
� � � The technical concept is now proven Next step: pilot parks to demonstrate cost reductions and open markets Large parks 500-1000MW is the end game objective Cost could reach 15-17 �/kWh by 2020

Concept 2003

Model test 2005

Full-scale prototype 2009

Pilot Park, 3-6 turbines
