The SGS Wind Energy Technology Center (WETC) in Tianjin, China was awarded a contract to conduct full-scale Wind Turbine Blade Testing for one of the world's leading component suppliers in the wind turbine industry on June 30, 2011.
During their operational life wind turbine blades are subjected to highly demanding forces and wind turbine blade failures can have a severe impact on safety, turbine downtime and public exposure. In order to validate the lifetime of the blades and minimize the risks from design flaws and manufacturing defects, one of the world's leading component suppliers to the wind turbine industry, looked for a reliable inspection, verification, testing and certification company.
On June 30, 2011, the SGS Wind Energy Technology Center (WETC) in Tianjin, China, the first third-party testing center for wind turbine blades in Asia, was awarded a contract to carry out full-scale Wind Turbine Blade Testing
Throughout the entire contract, SGS will carry out frequency, static and fatigue tests of a new blade design in accordance with the IEC-61400-23 standard. During frequency testing, SGS's team of highly-skilled engineers measure rotor blade displacement and analyze the natural frequencies of the blade, whereas during static testing blade deflection and strains are measured at pre-determined locations for all required loading directions. For fatigue tests, an exciter saddle with linear masses is mounted to the rotor blade and the dynamic load distribution and amplitude are adjusted to represent 20 years of cyclic field loads.
Applying a wide portfolio of services for Wind Turbine Blade Testing, the SGS Wind Energy Technology Center will provide the project owner with comprehensive certification testing, in compliance with IEC-61400-23, to ensure the best quality of the new wind turbine blade design.
