Only a few months after its sales launch at the EWEA Offshore trade show in Copenhagen, the new Siemens offshore flagship wind turbine of the type SWT-7.0-154 has now been installed as a prototype.
The planned field testing of the 7-megawatt (MW) offshore machine in Østerild, Denmark, mainly focusses on the upgraded generator and the enhanced electrical system.
The majority of other components are equal to the proven technology of the Siemens SWT-6.0-154 – including the rotor with its outstanding diameter of 154 meters. This latest edition of the D7 product platform can produce 32 million kilowatt hours of clean electricity under offshore wind conditions, enough energy to supply up to 7,000 households.
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.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
