Precise and reliable production of rotor blades is essential for the quality of the blades and thus for the service life and the possible energy yield of a wind turbine. Due to the high level of manual labor in the production process, the rotor blades often have defects which can develop into serious damage during operation. According to estimates by experts, approx. 4 out of 5 damage events in the field are related to the production process. As independent experts we perform inspections during blade production directly at the manufacturer’s site on behalf of the operator and prepare a complete documentation of any deviations in quality.
