The U.S. General Electric (GE) announced this week the launch of its new wind 4.1-113, a machine of the class of 4 megawatts, optimized for use at sea, and meant to provide a higher level of reliability.
“GE has signed an agreement with Göteborg Energi to provide the 4.1-113 wind turbine with service contract, for installation in the port of Gothenburg in Sweden in the second half of 2011,” GE also said at the annual EWEA (European Wind Energy) conference.
This project is supported by the Swedish Energy Agency through its technology program, demonstrates his interest in offshore technology advanced.
“We are proud to announce the next step in our strategic plan for the offshore industry. Our wind 4.1-113 is our most advanced technology. It is the only direct drive wind turbine designed exclusively for offshore, “said Victor Abate, vice president of renewables at GE Water & Power. “Göteborg Energi is an excellent partner and we receive with gratitude the support of local authorities for our project. ”
With fewer moving parts, technology allows direct transmission of a simple design and reliable with redundant capability and integrated part of the main components, to maintain reliable operation of the turbines offshore technology eliminates the direct transmission parts gear costly, reducing operating expenses, and is based on an innovative modular approach to maximize the repair in situ and reduce the need for maintenance vessels of large size.
In addition, the tapered design of 4.1-113 is optimized to maximize energy capture. It is based on the evolution of the direct transmission model 3.5 MW offshore wind turbine, direct drive. GE says that “the basic design work since 2005 on a coastal site in Norway, in a harsh environment with high winds and severe turbulence. It also stems from solutions developed for the park land from GE, including GE’s advanced solution for load control, which reduces the forces transmitted to the machine and minimize the costs of foundation.”
GE has also joined the Chalmers Wind Energy Center to help shape the landscape of Swedish wind power. Approximately 50 new jobs will be created by 2016 following GE’s investment in the country.
This project in the port of Gothenburg is part of the GE strategy in Europe, which represents an investment of 340 million euros in its offshore activities.
