9. Issued the first GWO blade maintenance training service certificate in Asia

On May 25, 2021, authorized by the global wind energy organization GWO, Jianheng Certification Center issued GWO BR (Blade repair training) to Goldwind Technology Co., Ltd. Offshore Wind Power Training Center (abbreviated as "Goldwind Technology Offshore Wind Power Training and Training Center") The blade maintenance training service certification certificate, the qualification achieved the "zero" breakthrough in the GWO blade maintenance training service module in Asia, providing guarantee for the domestic wind power industry to train blade operation and maintenance talents, and helping the industry to standardize and develop healthily.

Blade quality issues are related to the two important indicators of wind turbine reliability and power generation. In recent years, with the rapid development of the industry, the stock and incremental scale of wind power blades have become larger and larger, and there has been a huge market demand for blade operation and maintenance services. In the absence of professional inspection and maintenance, minor damage to the blades will gradually evolve into major damage. In severe cases, it will cause accidents such as the collapse of the wind turbine tower, resulting in huge economic losses. At the same time, the current blade service market is chaotic, and the skill level of operators is uneven. Standardized training of blade operation and maintenance personnel has become the top priority of the industry.
