The Dongying Offshore Wind Power Equipment Manufacturing Industrial Cluster is located on the Bohai Bay coast in east China’s Shandong province. Entering the cluster, one can see giant wind turbine towers, hundreds of meters high, stand like a forest, with their blades slowly rotating. At the dock, thousand-ton crawler cranes are steadily lifting the massive towers onto cargo ships. Inside the assembly workshop, production lines are operating at full speed, and workers are conducting final debugging and testing of wind turbine units tailored for different offshore projects.

Leveraging technological innovation, this industrial cluster has established a series of China’s leading public testing and certification platforms that serve the entire industrial chain across the country, providing a solid foundation for the wind power industrial cluster.

In the cluster, a large-scale R&D and testing center for offshore wind power electro-mechanical transmission systems has been established. Its main function is to construct a real-time simulation system that can verify the transmission systems, generators, converters, and main controllers of medium-speed and high-speed offshore wind turbines. This center boasts world leading simulation and testing capabilities.

Currently, the large-scale wind turbine blade testing platform that has been built and put into operation in the cluster can carry out large-scale tests such as fatigue tests and static tests on blades up to 150 meters long, making it the blade testing base with the highest testing capabilities in northern China.

At the Dongying Wind Power Equipment Testing and Certification Innovation Base built in the cluster, all twelve high-capacity wind power test berths and the comprehensive testing center have been completed and put into operation. Nine test units with a total capacity of 119.5MW have been installed and connected to the grid for testing, and adaptability testing is being carried out simultaneously.
