The new Siemens offshore wind turbine of the type SWT-7.0-154 has now been installed as a prototype. The planned field testing of the 7 MW offshore machine in àƒËœsterild, Denmark, mainly focuses on the upgraded generator and the enhanced electrical system.
The majority of other components are equal to the technology of the Siemens SWT-6.0-154 — including the rotor with its 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.
The prototype in àƒËœsterild, Denmark was installed only a few months after the product launch at EWEA Offshore trade show in Copenhagen.
In May 2011, Siemens installed the first prototype of its direct drive offshore wind turbine.
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.
