French engineering company Alstom have announced the completion of their at-sea installation of its new-generation offshore wind turbine, the 6MW Haliade 150, located off Ostend Harbour at the Belwind site in Belgium.
The turbine, the largest offshore wind turbine ever installed in sea waters, boasts a 78 metre tower, a nacelle that stands 100 metres above the waves, blades over 73 metres in length, and pillars sunk over 60 metres into the seabed to support the mammoth construction.
As a result of its impressive specifications, the Haliade sports a yield 15% better than existing offshore turbines, allowing it to power approximately 5,000 households on its own.
“This project with Belwind asserts our technological leadership and our innovative abilities,” said Alstom Wind Senior Vice-President Alfonso Faubel. ”The installation of our turbine which is simple, robust and efficient thus contributing in boosting the competitiveness of offshore wind energy.”
The Haliade operates without a gearbox, instead working with direct drive, and due to a permanent-magnet generator there are fewer mechanical parts inside the device, which not only makes it more reliable but also helps to minimise operating and maintenance costs faced by traditional offshore wind turbines. Given the specific expertise necessary to not only maintain a wind turbine, but one located offshore in likely-stormy waters, reducing operating and maintenance costs is a necessity many companies are striving towards.
“Belwind’s tried and tested expertise in completing offshore projects and setting up wind farms has helped Alstom to perform the installation work in sea waters under the best possible conditions,” said Belwind chairman Wim Biesemans. “We are convinced that Alstom’s innovative wind energy technology will contribute in providing one of the future solutions to ensure clean, reliable and efficient energy.”
