【Major Industrial Equipment in the Chemical Industry】461 – The tallest and heaviest offshore wind turbine jacket in Asia from 2021
Thread Content
At 12:00 on May 9, 2021, as the four main hooks of the vessel \"Xinzhenfu 7\" were slowly lowered, the jacket of the offshore step-up substation for the **Dian Tou Jieyang Shenquan No.1 offshore wind power project was successfully and smoothly placed on the seabed of the South China Sea. **The Jieyang Shenquan-1 Offshore Wind Farm, operated by Power Investment, is located in the eastern Guangdong region of the South China Sea. Its planned total installed capacity is 315.5 MW, with 53 wind turbines in total; it also includes a 220kV offshore step-up substation and an onshore centralized control center. The waters where the wind farm is located are deep and have strong waves, which imposes very high requirements on offshore structures. The jacket foundation of the offshore substation is 61 meters high, 40 meters long, and 39 meters wide, with a weight of 3,500 tons; it is currently the tallest and heaviest offshore wind turbine jacket in Asia. On May 7, the vessel “Xinzhenfu 7” entered the construction area and anchored there. With the careful organization and active coordination of the on-site project team, various challenges were overcome, including limited space on the transport vessels, strong currents and large waves in the construction area, as well as the fact that the lifting height was at its limit. After 48 hours of continuous effort, the jacket for the offshore substation of the **EP Power Jieyang Shenquan-1 Offshore Wind Project was successfully installed. This project marked the first time that the vessel \"Xin Zhenfu 7\" successfully completed the jacket installation task in the waters of Guangdong.
Great! The tallest and heaviest offshore wind turbine jacket in Asia
**The first batch of 5 5.5-megawatt wind turbines at the Jieyang Shenquan-1 offshore wind project operated by Power Investment Guangdong Company have been connected to the grid for power generation. **The Dian Tou Shen Quan 1 offshore wind power project has a capacity of 315.5 megawatts; 16 wind turbines with a capacity of 7 megawatts each and 37 turbines with a capacity of 5.5 megawatts each are planned to be installed, and the project is set to be connected to the grid at full capacity this year. Once operational, the project is expected to supply 1 billion kWh of clean electricity to society each year, saving 300,000 tons of standard coal consumption, and reducing CO₂ emissions by 780,000 tons, dust by 31 tons, sulfides by 108 tons, and nitrogen oxides by 154 tons ； It creates more than 1,000 jobs in the surrounding area.
