Super burning! The world's first anti-typhoon floating offshore wind turbine "settled" in Yangjiang, Guangdong
2021-07-15 15:21:12

At 11:28 on July 13, China Three Gorges New Energy (Group) Co., Ltd. (stock abbreviation "Three Gorges Energy", stock code "600905") invested and constructed China's first floating offshore wind power platform, equipped with the world's first Typhoon-resistant floating offshore wind turbines, forming the "Three Gorges Pilot", were successfully installed in the Shapa million-kilowatt offshore wind farm in Yangjiang, Guangdong. This means that China's floating wind turbines and basic platforms with completely independent intellectual property rights are moving forward. The exploration pace of the acquisition of far-reaching wind energy resources.


This floating offshore wind turbine and platform is located in the South China Sea, with a stand-alone capacity of 5.5 MW. It is led by Three Gorges Energy and is independently developed by the Three Gorges Group Shanghai Survey, Design and Research Institute and other scientific research institutions through the "integration of production, education and research" mode, as well as domestic wind turbine manufacturers It is of positive significance to promote the upgrading of my country's offshore wind power high-end equipment manufacturing and tap the potential of far-reaching offshore wind energy resources.

It is reported that floating offshore wind power is expected by the industry as "the main technology for the development of far-reaching offshore wind power in the future" and has been explored in many countries and regions. Compared with traditional wind turbines fixed on the offshore seabed, floating turbines can realize the vision of deploying wind turbines in far-reaching seas. While obtaining stable and high-quality wind power resources in far-reaching waters, they will not affect the nearshore fishery, aquaculture, navigation and navigation. Other related industry activities. However, it is not easy to follow the waves and deep sea. The global floating offshore wind power generally faces difficulties in technology, cost and low maturity of the industrial chain.

Since 2018, relying on the relevant scientific research projects of Guangdong Province, the relevant enterprises of the Three Gorges Energy Joint Industry Chain have successively overcome the conditions of frequent typhoons, complex sea conditions, and harsh waves, such as anti-typhoon wind turbines, semi-submersible foundations and mooring systems, dynamic cable design, The key technologies of floating offshore wind power such as integrated installation and towing, integrated installation of wind turbines and platforms, and the main solutions are all domestic independent core technologies.

The height of the hub center of the "Three Gorges Leader" is about 107 meters above sea level, which is equivalent to the height of nearly 37 floors of residential buildings; the diameter of the impeller is 158 meters, which is equivalent to the width of three Boeing 747s side by side; the sweeping area of the wind wheel is equivalent to three standardized football field. The basic platform and wind turbine are designed according to the extreme wind, wave and current conditions that occur once in 50 years. The displacement of the floating platform is about 13,000 tons, which is equivalent to the displacement of a 10,000-ton giant ship. To this end, the installation team has continuously optimized the construction technology, created the first high-precision suction anchor that can be positioned to 0.01 meters in the country, and overcomes the integrated towing of large-capacity wind turbines under complex sea conditions, and the integrated positioning of wind turbines and platforms.

The "Three Gorges Pilot" is planned to be put into operation at the end of 2021, and will deliver 16.5 million kilowatt-hours of clean electricity to the Guangdong-Hong Kong-Macao Greater Bay Area. At the same time, it will reduce standard coal consumption by 5,100 tons and carbon dioxide emissions by 13,800 tons. The application provides valuable experimental data and optimization space. In the long run, it is an inevitable trend for offshore wind power to move from offshore to far-reaching waters. As the main body of the implementation of the new energy business strategy of the Three Gorges Group and the current new energy listed company with the highest A stock market value, Three Gorges Energy carries the historical mission of "playing a leading role in promoting the upgrading of the clean energy industry" and will continue to focus on floating wind power research and development , Strengthen forward-looking scientific research work, help the development of China's far-reaching offshore wind power projects steadily and far-reaching, contribute to the Three Gorges power for the high-quality expansion of China's clean energy, and help achieve the goal of "carbon peak and carbon neutrality".

Adopting Mingyang Intelligent's world's first anti-typhoon floating offshore wind turbine

The project is designed by Shanghai Survey and Design Institute, Wison Offshore is responsible for the construction of the foundation platform, and Guangzhou Salvage Bureau is responsible for the offshore construction.

The wind turbine hoisting and installation work was completed by Sinopec Shipping Company's own 1250-ton crawler crane at the terminal of Maoming Port in Guangdong. From the open site to the towering wind turbine, from the 1250-ton crawler crane assembly, unloading, shifting to the completion of hoisting, after 6 days and 5 nights of continuous operation, the hoisting project department uses superb hoisting technology and reasonable overall arrangements to boost wind power Project construction progress. On July 9th, with the final three-bladed hub and the nacelle docking steadily at high altitude, the world's first anti-typhoon floating offshore wind turbine was successfully hoisted.

On July 11, the world's first anti-typhoon floating offshore wind turbine "Three Gorges Pilot" set off from Maoming Port, Guangdong, under the guidance of a tugboat, arrived at Yangjiang Offshore Wind Farm and began to install mooring cables.

On July 13, the world's first anti-typhoon floating offshore wind turbine was successfully installed in Yangjiang, Guangdong.

This is China's first floating offshore wind turbine to be launched into the sea, ushering in a new era of floating offshore wind power in China, and is also a major milestone for China's offshore wind power to enter the deep sea.

2. Preparation of permanent mooring line

On May 25, the first domestic offshore floating wind turbine permanent mooring line independently developed and produced by Juli Rigging successfully passed the acceptance.


On June 7, the permanent mooring line for offshore floating wind turbines was laid underwater at the Yangjiang project site in Guangdong, laying a solid foundation for the subsequent installation of the floating foundation platform for offshore wind turbines.
