Main construction of China’s first far-reaching floating offshore wind power platform has been completed in Qingdao, East China's Shandong Province on Monday, CCTV reported. The platform will be world's first offshore wind power project in water depths exceeding 100 meters with an offshore distance exceeding 100 kilometers.
The platform will be installed in seas 136 kilometers offshore from Wenchang, South China’s Hainan Province. When put into operation, the project can generate 22 million kilowatt hours of electricity annually and reduce the carbon dioxide emissions by 22,000 tons.
The platform is financially backed and constructed by China National Offshore Oil Corporation (CNOOC), and is designed with the capacity to resist high winds and waves in the sea area. It can resist super typhoons with a maximum of level 17 and above and wind speed of 84 meters per second, according to CNOOC.
By optimizing the scale of the platform, adding efficient damping structure and other technical innovations, the tilt the floating wind power platform under the action of extreme typhoons is less than 10 degrees, which can effectively prevent fan blades being damaged by waves, according to Hua Bin, the project’s manager.
The project is China’s first to have independently developed and constructed far-reaching offshore floating wind power with internationally advanced level in investment per megawatt, steel per megawatt, among other indicators.
China's installed capacity of offshore wind power has continued to expand with accumulated installed capacity reaching 32.5 million kilowatts by 2022, remaining the world's largest in installed capacity of offshore wind power.
The country is also accelerating the development of offshore wind power to more remote sea areas. Currently, China's floating offshore wind power installed capacity ranks the fourth in the world. It is expected that by 2026, the accumulated installed capacity is expected to exceed 500,000 kilowatts.
