Floating Offshore Wind Turbines

China rolled out the world's largest single-unit floating offshore wind turbine in October 2025 — a 16MW direct-drive unit with the world's largest rotor diameter, deployed in waters over 50 meters deep off Guangxi province. Mingyang Smart Energy followed with plans for a 50MW twin-head floating platform (Ocean-X concept), which would be the largest wind turbine ever designed.

Floating offshore wind unlocks a vast resource: most of the world's best offshore wind sites are in waters deeper than 60 meters, where traditional fixed-bottom turbines cannot be installed. Floating platforms, moored to the seabed with cables, can access these deep-water sites. China's South China Sea, with strong sustained winds and depths exceeding 100 meters, is a prime target. China Huaneng Group and Mingyang are leading the push.

The technology addresses a specific gap in China's renewable energy portfolio: onshore wind and solar face land-use constraints, while fixed-bottom offshore wind is limited to shallow coastal waters. Floating wind could add hundreds of gigawatts of capacity in the South China Sea, Taiwan Strait, and East China Sea — areas with dual energy and geopolitical significance. China's manufacturing cost advantage in turbines, platforms, and installation vessels gives it a structural edge as the global floating wind market scales.
