升顶成功！实现毫米级精准就位

Group 1 - The Jiangsu Huadian Ganyu LNG receiving station, the first LNG project involving a state-owned power enterprise, has successfully completed the gas pressure topping operation for its first storage tank [1][3] - The project is designed to construct three LNG storage tanks, each with a capacity of 220,000 cubic meters [1] - Once operational, the project is expected to supply 4.2 billion cubic meters of natural gas annually [1] Group 2 - The topping operation, known as "gas topping," is the most complex and challenging phase in the construction of LNG storage tanks [3] - The operation involves four high-power specialized fans that continuously output stable airflow to lift a nearly thousand-ton "steel cap" to the top of the storage tank, achieving millimeter-level precision [3]
