2. The first "million kilowatt-level" offshore wind power base set multiple records

The Three Gorges Yangjiang Shapa Offshore Wind Power Project is located in the sea area south of Shapa Town, Yangjiang City, Guangdong Province. It has a total installed capacity of 1.7 million kilowatts and a total of 269 offshore wind turbines. The project has built 3 sea booster stations, using 220 kV submarine cables. Access to the land-based centralized control center. This project is the first "million kilowatt-level" offshore wind power base in China, and is a pioneer in the development of my country's offshore wind power on a large scale.

The project innovatively used a variety of construction techniques and foundation forms, among which multiple foundation forms such as suction tube jacket, single-column composite tube, core-column rock-socketed jacket, and large-diameter four-pile jacket were used for the first time in China and completed. At present, the jacket foundation of the inclined pile-socketed rock-socketed sea rising pressure station is the only one in the domestic offshore wind power industry. At the same time, the project has set a record of domestic offshore wind power construction speed many times during the construction process.

It is estimated that after the completion of the Yangjiang Offshore Wind Power Project, it will provide 4.7 billion kilowatt-hours of on-grid electricity, which can meet the annual electricity consumption of about 2 million modern households. Compared with coal-fired power plants of the same scale, it can save about standard coal every year. 1.5 million tons of carbon dioxide emission reduction of about 4 million tons will provide strong support for the transformation of the energy structure of the Guangdong-Hong Kong-Macao Greater Bay Area.

6. The drilling rate of the world's first Type Ⅲ single pile breaks a domestic record

Recently, the world's first pressurized drilling vertical roadheader developed by China Jiaotong Tianhe completed the largest offshore rock-socketed single pile drilling in China in just 26 days, setting a new type III single pile drilling record.

The offshore wind power project is located in the sea area of Xiuyu District, Putian City, Fujian Province, and has 19 sets of 7 MW offshore wind turbines. In order to make these giants stand more stable, the researchers designed a hole with a depth of 25.4 meters, which is equivalent to a 9-story building. After the machine pile is driven into the seabed rock, the depth of the rock-socketed hole in the weakly weathered hard rock is 18.4 meters, and the hole diameter is 7 meters.

According to reports, the equipment has a maximum lifting force of 900 tons and a maximum drilling diameter of 10.4 meters (the drilling diameter of mainstream equipment at home and abroad is 4.7-6 meters), and uses an intelligent drilling control system to make the equipment easy to operate and realize drilling. One-click start of construction. Its super-torque drive system can provide power support for rapid excavation. In fully weathered and moderately weathered rock formations, the drilling speed of this equipment can reach 20-40 mm/min, and the drilling speed of slightly weathered and weakly weathered rock formations can reach 10 mm/min. Minutes, comprehensive capacity and drilling speed are ahead of the current domestic and foreign traditional equipment.
