StatoilHydro Inaugurates Floating Wind Turbine Hywind Pilot

Published: 08-Sep-2009

StatoilHydro ASA (StatoilHydro) has inaugurated its full-scale floating wind turbine Hywind pilot in the North Sea on September 8, 2009. The floating wind turbine has been delivered within budget and on schedule. Hywind comprises a 2.3 MW wind turbine installed on a traditional floater of the kind previously used for such applications as production platforms and offshore loading. The turbine has been manufactured by the Siemens Wind Power company in Denmark.

“Today, we’re inaugurating the pilot facility which could help floating wind turbines to make an important contribution in the longer term to meeting the world’s big demand for energy,” says Margareth Øvrum, executive vice president for Technology & New Energy (TNE) in StatoilHydro.

StatoilHydro is investing about NOK340 million in the project, with Enova providing NOK59 million. The latter is a state-owned company which promotes environment-friendly changes to energy production and use in Norway.

France’s Technip built the floater and Nexans produced and laid the power cable to land.

Following assembly in the Åmøy Fjord near Stavanger, the Hywind pilot was towed in June 2009 to a location 10 kilometres south-west of Karmøy island for a two-year test period.

“Floating wind power remains an immature technology, and the road to commercialisation and full-scale construction of wind farms will be long,” says Øvrum.

“Our goal with the Hywind pilot to test how wind and waves affect the structure, learn how the operating concept can be optimised and identify technology gaps.”

Hywind:

The tower is 65 metres high, supporting rotors 80 metres in diameter.

The floater has a draught of 100 metres, and is attached to the seabed by a three-point mooring spread.

Hywind is suitable for water depths of 120-700 metres.

The whole structure weighs 5,300 tonnes.

The pilot is to be tested over two years.

No serious health, safety or environmental incidents have occurred during the Hywind development.
