The company has so far procured an agreement with Denmark's DONG Energy for 300 of the 6-MW turbines for use in projects off the coast of the UK. Siemens is expected to install two more SWT-6.0 prototypes in the UK Gunfleet Sands project, marking the first time that the Siemens 6-MW wind turbine will be tested offshore. Both turbines for that project will be equipped with the 120-m rotor.
