DNV GL and Siemens Wind Power (Siemens) today announced that the Siemens SWT-3.6-130 Onshore Direct Drive Platform wind turbine has been successfully type certified by DNV GL. This certification confirms that the new turbine complies with all the requirements of the international wind turbine standard IEC 61400-22 for conformity testing and certification.
The SWT-3.6-130 is the 2nd generation of wind turbine from the Onshore Direct Drive Platform. It features larger blades than previous generation of wind turbines, giving a rotor diameter of 130 meters. Thanks to this and additionally technical innovations and developments throughout the wind turbine, the SWT-3.6-130 will according to Siemens deliver 18-19% higher annual energy production across wind speeds than the previous model SWT-3.2-113 of the first generation of direct drive wind turbines. Siemens Wind Power offers the turbine with various hub heights.
As wind power has become mature and widespread, wind farm developers are facing the prospect that the sites with the best wind conditions have already been developed. They now have to investigate locations with less optimal wind conditions. To help them develop such sites cost-effectively, Siemens created its new Onshore Direct Drive Platform that maximizes yields in low- to medium- winds.
“Type certification of wind turbines is crucial for securing financing of new wind farm projects. Hence, it is an important factor in time to market for new turbines. “We have a more than 20-year working relationship with DNV GL’s wind experts. This experience and knowing the internal processes on both sides helps a lot to streamline the type certification procedure, allowing us to meet our given tight deadlines” said Jonas Stenzel, Head of Global Product & Technology Type Certification for Siemens Wind Power.
“We have been working with Siemens since their earliest days in wind power. We are very proud to support them in their continuous efforts to deliver more efficient wind turbines to move the industry forward. Through an efficient type certification process, we help Siemens demonstrate they can deliver compliant products on time and provide trusted, independent certification for a hassle-free market entrance,” said Christer Eriksson, Service Line Leader for Type Certification.
The certification process for the SWT-3.6-130 began with the certification of the prototype installed at Høvsøre, Denmark. The type certification included evaluation of the design supported by tests and measurements as well as inspections. Following the finalization of the type certification process, the official certificate has been handed over to Siemens at the WindEnergy Hamburg exhibition on the 28th September 2016.
