Global engineering company Siemens Wind Power has secured a type certificate for its SWT-3.6-130 onshore wind turbine from DNV GL.

Global engineering company Siemens Wind Power has secured a type certificate for its SWT-3.6-130 onshore wind turbine from DNV GL.

The certification establishes that the SWT-3.6-130 complies with all the requirements of the international wind turbine standard IEC 61400-22 for conformity testing and certification.

Siemens Wind Power's global product & technology type certification head Jonas Stenzel said: “Type certification of wind turbines is vital for securing financing of new windfarm 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. Their technical expertise helps us raise our own quality level and they were able to streamline the type certification procedure, allowing us to meet the deadlines for an 800MW project opportunity.”

The SWT-3.6-130 is the second product developed by Siemens in the Onshore Direct Drive category, which features large blades in comparison to previous turbines. The blades also weigh much less than earlier turbine models and the company claims its new turbine has the ability to deliver 19% higher annual energy production in low winds than the D3 Mk I.

DNV GL's type certification service line leader Christer Eriksson said: “We have been working with Siemens since their earliest days in windpower. 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.”

The certification process for the SWT-3.6-130 began with the certification of the prototype installed at Høvsøre, Denmark. It is currently available in heights of 85m, 115m and 135m.
