At 22:13 on July 15th, at an altitude of 115 meters in the South China Sea, Shapa Town, Yangjiang City, Guangdong Province, with the precise docking of the F34 fan impeller and the engine room, the project was invested and constructed by China Three Gorges New Energy (Group) Co., Ltd. Asia’s largest single-capacity offshore wind farm under construction-the Three Gorges Guangdong Yangjiang Shapa Offshore Wind Power Project has a wind turbine hoisting capacity exceeding 1 million kilowatts, marking the country’s first million kilowatt offshore wind farm from a blueprint to reality.

It is understood that the Three Gorges Shaba project has a total of 5 phases planned, with a total installed capacity of 1.7 million kilowatts, installation of 269 offshore wind turbines, construction of 3 offshore boosting stations, and 220kV submarine cables connected to the onshore centralized control center. After the project is fully completed, it can provide about 4.7 billion kilowatt-hours of on-grid power annually, which can meet the annual power consumption of about 2 million households. Compared with coal-fired power plants of the same scale, it can save about 1.5 million tons of standard coal each year and reduce carbon dioxide emissions. Approximately 4 million tons will provide strong support for the transformation of the energy structure of the Guangdong-Hong Kong-Macao Greater Bay Area.
Geological conditions are the difficulty of offshore wind power development. Faced with challenges such as complex sea geological and climate environment, difficult construction technology, and high-strength construction organization, the Three Gorges Sand Bar project innovatively uses a variety of construction technologies and basic forms, among which suction canisters Jackets, single-column composite cylinders, core-column-type rock-socketed jackets, large-diameter four-pile jackets and other foundation forms are used for the first time in China, and the only inclined pile-socketed rock-socketed sea rising pressure station conduit for offshore wind power in China has been completed. Frame foundation. At the same time, during the construction process of the project, the construction “window period” was fully grasped, and the technology was continuously optimized and the work efficiency was improved. From the hoisting of 18 units in March this year, to the hoisting of 22 units in April, and then to the hoisting of 31 units in May, the speed of fan hoisting continued. Refresh the domestic offshore wind power construction speed record.
China has a natural advantage in the development of offshore wind power, with a coastline of 18,000 kilometers and a usable sea area of ​​more than 3 million square kilometers. The offshore wind energy resources are abundant. The concentrated and large-scale development of offshore wind power will effectively improve the efficiency of sea area resource utilization and reduce projects. Construction and operating costs.
