Siemens Energy has begun field-testing the new 154-meter rotor for its 6 MW offshore wind turbine in Osterild, Denmark. According to the company, the turbine is equipped with the world's longest rotor blades, which measure 75 meters.

In May 2011, Siemens installed the first prototype of its SWT-6.0-154 wind turbine, which had a 120-meter rotor, and it has been operating for well over a year. However, the serial version of the 6 MW turbine will use a 154-meter rotor, Siemens says.

According to the company, the turbine's gearless drive technology gives it a compact design, and the nacelle weighs just 200 tons. In addition, the blades are up to 20% lighter than blades manufactured with traditional methods, according to Siemens.

The company has already signed agreements to deploy the new SWT-6.0-154 turbines. In July, Siemens entered a deal with DONG Energy for the delivery of 300 SWT-6.0-154 turbines, which will be used for wind projects off the coast of the U.K.

The company will soon install two more SWT-6.0 prototypes at Gunfleet Sands, a British offshore wind power plant. This will be the first time that the Siemens 6 MW wind turbine will be tested offshore, the company notes. Both machines for this project will be equipped with the 120-meter rotor.
