Siemens installs offshore wind turbine SWT-7.0-154 prototype

Siemens today revealed that it has installed the offshore wind turbine SWT-7.0-154 as a prototype.

The company announced the sales launch of SWT-7.0-154 at the EWEA Offshore trade show in Copenhagen.

Siemens is aiming for serial production within two years.

The field testing of the 7-megawatt (MW) offshore machine in Osterild, Denmark, mainly focuses on the upgraded generator and the enhanced electrical system. Siemens is using the majority of other components of the Siemens SWT-6.0-154 – including the rotor with its outstanding diameter of 154 meters.

Siemens said that the 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.

“Based on the 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,” said Morten Rasmussen, head of Technology at Siemens Wind Power and Renewables Division.

In a statement, Siemens said the new design and low weight reduces offshore infrastructure, installation and maintenance costs. Cranes and installation vessels available today will be sufficient for its installation.

The new Siemens offshore machine will 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.
