On January 11, "Qihang," the world's most powerful floating offshore wind turbine, was successfully installed in Dongying, Shandong, marking a significant milestone for CRRC in the exploration of ultra-large offshore wind turbines.
Qihang is a 20MW floating offshore wind turbine independently developed by CRRC, with a power output of 20 megawatts. The turbine features a wind rotor diameter of 260 meters, a sweeping area equivalent to over seven standard football fields, a blade tip speed matching that of a high-speed train, and a hub height of 151 meters. Each unit can generate up to 62 million kilowatt-hours of clean electricity annually, saving about 25,000 tons of coal and reducing carbon dioxide emissions by approximately 62,000 tons.
Qihang integrates multiple innovative control technologies, offering four core advantages: high intelligence, system modularization, full-chain collaboration, and exceptional stability. It incorporates various intelligent control, sensing, and detection technologies. The design further enhances the unit's flexibility and efficiency by modularizing key system interfaces and structural components. With its floating stability design that is resistant to waves and winds, it features customized components with low failure rates, high fault tolerance, and strong vibration resistance, and extensive experimental validation ensures safe, stable, and reliable operation. Furthermore, CRRC has established a complete wind power equipment supply chain, supporting leadership in product performance and core technology.
The Qihang turbine is engineered to significantly increase customer profitability, reduce the levelized cost of electricity (LCOE), and set new standards in the wind power industry.
