China has installed what officials describe as the world’s largest floating offshore wind turbine in deep waters off the country’s southern coast, marking a major step in renewable energy technology.
The project, called the Three Gorges Pilot, was deployed near Yangjiang in Guangdong province by China Three Gorges Corporation. Company representatives announced the installation in a statement released May 3.
The 16-megawatt turbine was designed for offshore areas where water depths make traditional fixed-bottom wind farms difficult and expensive to build. Unlike conventional offshore turbines anchored directly into the seabed, the new system sits on a massive semisubmersible floating platform secured with advanced mooring technology.
Turbine built for deep-sea conditions
The turbine has a rotor diameter of 827 feet (252 meters), while the blade tip reaches more than 886 feet (270 meters) above sea level. Engineers said the platform was developed to withstand harsh marine conditions, including waves higher than 66 feet (20 meters) and wind speeds up to 164 mph (264 kph), equivalent to a Category 5 hurricane.
To stabilize the structure, developers installed a mooring system that combines suction anchors, heavy anchor chains, and high-strength polyester cables. The platform also uses ballast controls and monitoring systems to maintain balance and reduce drifting in rough seas.

Engineers equipped the turbine with a 66-kilovolt dynamic subsea cable designed to move and flex with the floating structure while transmitting high-voltage electricity underwater. The cable uses a wave-shaped design with reinforced armor layers and fatigue-resistant insulation to handle constant motion in the ocean.
Most of the turbine was assembled at Tieshan Port in southern China before being towed offshore for final installation and testing.
The project could expand offshore wind development
At peak operating capacity, the turbine is expected to generate about 44.65 million kilowatt-hours of electricity each year. Based on figures from the U.S. Energy Information Administration, that would be enough to power roughly 4,200 average American homes annually.
The installation highlights growing interest in floating offshore wind technology, which many energy experts see as an important tool for expanding renewable power generation. Large areas of the world’s strongest offshore winds are located in waters too deep for traditional wind farm foundations.
Floating turbines present major engineering challenges because the structures must operate continuously while moving with waves and ocean currents. Engineers must protect turbine components from long-term stress while maintaining stability and safe blade clearance above the water.
Supporters say projects like the Three Gorges Pilot could help open deeper offshore regions to commercial-scale wind energy development, especially in countries with limited shallow coastal areas suitable for fixed-bottom turbines.
