A German inspection firm is to certify a Chinese-designed offshore wind turbine. TUV Nord will perform type certification on Sinovel’s 6 MW wind power system that will help the company expand into international offshore wind markets. 

TÜV NORD claims the turbine will be one of the first Chinese-designed offshore wind power systems with internationally recognised type certification.

The Sinovel SL6000 prototype wind system has a 6 MW capacity and a ‘high speed squirrel cage asynchronous’ generator. The rotor, with a 128m diameter, has a swept area of 12,868sqm.

TÜV NORD explains that in order to demonstrate product quality Sinovel wishes to achieve certification from an independent party.

Lars Sitzki, head of TÜV NORD wind power services in Hamburg, Germany, said: "With the support of our colleagues at TÜV NORD China, we have identified considerable demand for internationally recognised certification in China. Such certification enables manufacturers like Sinovel to demonstrate compliance with international standards. This is essential in order to play a part in global wind farm projects."

The certification process involves a series of stages, including a design assessment, a type test and product monitoring. The first step is the design assessment, which will involve TÜV NORD critically reviewing the parameters that Sinovel’s engineers have calculated. In addition, some of the components undergo testing. The final part of type certification involves production monitoring. This will involve TÜV NORD conducting inspections at Sinovel and its component suppliers to make sure that the products comply with the designs and quality requirements. 

TUV Nord said: “The certification body determines whether the turbine is able to withstand stress and yields the specified output.”
