China’s state-owned CRRC Corporation, renowned for its high-speed trains that can reach speeds of 280 mph, has ventured into a new industry: offshore wind turbines.
A new standard for offshore wind turbines. CRRC recently launched Qihang, the world’s largest floating wind turbine. This impressive structure features a tower that stands at 495 feet tall and has a rotor with an 853-foot diameter. For context, the Trump World Tower in New York City is 861 feet tall.
Qihang sets a new standard in offshore wind energy, with only China competing against itself in this sector. With a capacity of 20 MW, Qihang surpasses the previously deployed floating wind turbines from Envision Energy (16.6 MW) and Dongfang Electric (18 MW), both introduced in 2024. However, Qihang will soon be outdone by Mingyang Wind Power’s upcoming 22 MW model.
Like a high-speed train. The Qihang wind turbine boasts a maximum rotational speed comparable to that of CRRC trains. It can generate up to 62 GWh of energy annually, which is enough to power 37,000 homes per turbine.
The Qihang turbine’s design is a remarkable example of modular architecture. It supports several power configurations and adapts to different floating platforms and mooring systems. Constructed from materials that can endure extreme conditions, such as typhoons, it features more than 200 sensors on its blades, structures, drive systems, and moorings for comprehensive monitoring.
First test unit. On Oct. 10, 2025, the first Qihang turbine left CRRC’s factory in Sheyang, Eastern China. In December, it arrived in Dongying, 300 miles away, and was transported to the testing site at Guangli Port using self-propelled modular barges.
By Jan. 11, the turbine was fully assembled and began a rigorous testing and certification phase before its final offshore transfer and connection to the power grid.
China’s dominance. China has now surpassed Europe in offshore wind power installations, overtaking the United Kingdom to become the world leader in this sector. The development of these massive floating turbines further solidifies this global leadership.
Only Chinese companies are currently developing turbines larger than 20 MW due to the logistical challenges faced in other regions. Floating technology allows for wind power generation in deeper waters farther offshore, facilitating the decarbonization of the power grid without affecting the coastal landscape.
