1. The first floating installation of a sea fan in China!

Recently, the C54-station wind turbine nacelle of the Changle Offshore Offshore Wind Farm Project in Fujian Province, which was constructed by the General Contracting Branch of China Communications First Aviation Company, successfully completed the installation of the C54 station wind turbine cabin. This installation uses a crane vessel for floating installation. This is the first domestic The installation of large megawatt wind turbines floating offshore, this technological innovation will greatly promote the construction innovation of the offshore wind power industry.

The wind turbine nacelle hub installed this time has a center height of 120 meters, a weight of 510 tons, and a unit capacity of 10 MW. It is currently the largest commercial offshore wind turbine in China.

5. Electric wind power self-developed 100-meter offshore wind power blades went offline smoothly

On September 1, Shanghai Electric Wind Power Group independently developed the 100-meter-class wind turbine blade S102 successfully rolled off the production line. The blade is 102 meters long and is designed in accordance with GL2015 and IEC61400-5 standards to meet the offshore category I typhoon wind area. The off-line of the blade marks the official entry of electrical wind power into the era of offshore wind power 100-meter blades!

The research and development of S102 blades adopts a variety of high-precision technologies, which greatly guarantees and improves the working efficiency and stability of the blades, and reflects the strong technical research and development capabilities of electric wind power.

6. Zhenhua Heavy Industry launched the world's largest piling ship

On August 31, the launching ceremony of the 140-meter piling ship "Yihangjin Pile 1" built by Zhenhua Heavy Industries was held at Qidong Offshore. "Yihangjin Piling 1" is currently the world's largest piling vessel. The ship is 124 meters in length, 39 meters in width, 8 meters in depth, and 142 meters in height. The maximum pile length that can be driven is 118 meters + water depth and weighs 700 tons. , The pile foundation with a diameter of 6 meters is suitable for the construction requirements under the severe sea conditions in the open sea. It is used for the construction of offshore wind power high-pile cap piles, jacket piles and large beam pile foundations, and it is sealed and towed in the unlimited navigation area.

After completion, it will become a dedicated piling engineering ship with the highest piling frame height, the largest piling capacity, and the strongest wind and wave resistance in the world.

7. The foundation construction of the Yudean Yangjiang Shapa offshore wind power project is completed and the grid will be connected to the grid at the end of the year

It was learned from the China Railway Bridge Bureau on August 31 that on that day, the foundation construction of all wind turbines for the Yudean Yangjiang Shapa Offshore Wind Power Project was successfully completed. The project plans to connect all wind turbines to the grid for power generation by the end of 2021.

The project is a key construction project in Guangdong Province and one of the most difficult offshore wind power projects in China. The Yudean Yangjiang Shapa Offshore Wind Power Project is located in the sea area southeast of Shapa Town, Yangxi County, Yangjiang City, Guangdong Province, covering an area of approximately 48 square kilometers. The total installed capacity of the project is 300 MW. One wind turbine with a single capacity of 5.5 MW and 46 wind turbines with a single capacity of 6.45 MW are selected, with a total investment of approximately RMB 6 billion.
