| Siemens installs prototype of its 7-megawatt offshore wind turbine ![]() In May 2011, Siemens installed the first prototype of its direct drive offshore wind turbine, while in the meantime the direct drive wind turbine has become the benchmark in the offshore wind industry. "The installation of the 7-MW version is an exciting step in its further development", says Morten Rasmussen, Head of Technology at Siemens Wind Power and Renewables Division. "Based on the reliable technology and supply chain of our six megawatt machine we have improved our flagship wind turbine with stronger permanent magnets, optimized generator segments and upgraded converter and transformer units. With only these minor changes we expect to get it ready for serial production within only two years." The gearless drive technology permits a compact design: Using Siemens' Direct Drive technology the SWT-7.0-154 is the lightest turbine of its class. The combination of robust design and low weight reduces offshore infrastructure, installation and maintenance costs. Today's cranes and installation vessels will be sufficient for its installation. With the SWT-6.0-154 Siemens experienced a tremendous success of its direct drive offshore technology. Gearless Siemens turbines have been selected for around ten projects. The first of them are already in operation. The new Siemens offshore machine will strongly contribute to lowering the levelized cost for offshore electricity: The SWT-7.0-154 model yields nearly 10 percent more power than its predecessor at comparable operational costs. Due to the upgraded electrical system it provides increased reactive power capabilities, important for grid code compliance. Advanced technology based on a proven platform will assure high reliability and maintainability. write your comments about the article :: © 2015 Construction News :: home page |
