In a groundbreaking move towards sustainable energy, China has launched the world’s largest floating wind turbine, the “Qihang,” which promises to significantly reduce carbon emissions and set new standards in renewable energy technology.
The “Qihang” turbine exemplifies a remarkable leap in renewable energy technology. Independently developed by Chinese sate-owned CRRC Corporation Limited, this 20 MW floating offshore wind turbine stands out due to its immense scale and capacity. Its typhoon-resistant design ensures exceptional stability, even in the most extreme weather conditions. With a rotor diameter of 260 metres, equivalent to seven football fields, it sets new standards in size and power. Its 151 metres hub further accentuates its imposing stature, making it the largest floating wind turbine globally. Each turbine avoids the use of about 24,750 metric tons of coal annually, and a reduction of 61,650 metric tons of CO2 per year.
With the development of the Qihang, China solidifies its position as a global leader in the wind energy sector. The country has already surpassed the UK to have the largest installed base of offshore wind turbines. China is rapidly extending its influence in the international wind energy market, particularly in Europe – and this is just the beginning of its international expansion in the off-shore sector.
The Qihang incorporates cutting-edge technologies. Equipped with over 200 test points covering every critical aspect of the turbine—from blades to transmission chains, towers, floaters, and mooring systems—these test points collect data on three-dimensional wind conditions, waves, and six degrees of freedom dynamic response allows for comprehensive performance analysis and efficiency.
