Siemens launches 6 MW direct drive offshore wind turbine

Siemens has been active in the offshore wind power sector since the company installed its first offshore wind power plant in 1991

Amsterdam, Netherlands, November 29, 2011 — Siemens Energy launched its new 6-MW direct drive wind turbine at the European Offshore Wind Energy Conference in Amsterdam, The Netherlands.

The new SWT-6.0 will be available with rotor diameters of 120 and 154 meters and features the Siemens direct drive design with 50 percent fewer parts than comparable geared wind turbines.

Siemens has been active in the offshore wind power sector since the company installed its first offshore wind power plant in 1991.

Since then, Siemens has installed more than 700 offshore wind turbines with a combined capacity of more than 2,000 MW in European waters. In offshore wind power alone, Siemens has an order backlog of more than 1,100 offshore wind turbines with a total capacity of more than 4,000 MW.

The new Siemens 6-MW wind turbine is purpose-built to endure the harshest conditions offshore. This direct drive wind turbine is offered with two different rotor blades. The SWT-6.0-154 features the largest rotor blade in the 6-MW class, using the new B75 Quantum Blade.

The first prototype of the Siemens 6-MW turbine was installed in May 2011 at Høvsøre, Denmark. Siemens is currently in the process of thoroughly testing and validating the performance of the turbine.
