On December 19, the pneumatic jacking operation for the first storage tank at the Jiangsu Huadian Ganyu LNG receiving station was successfully completed. It is reported that this project will enhance the flexibility and reliability of gas supply in the region, further improve the **single-gas-network infrastructure**, optimize the energy structure of the Yangtze River Delta, and provide strong impetus for the region’s green transformation. The project calls for the construction of 3 LNG storage tanks with a capacity of 220,000 cubic meters each. It will be funded and built jointly by Huadian Jiangsu Energy Co., Ltd., a subsidiary of China Huadian, and various foreign companies, with CNNC Fifth Engineering Company, a subsidiary of China National Nuclear Corporation, responsible for the construction work. Located in the Ganyu Port Area of Lianyungang, Jiangsu, the project is a key strategic move for Jiangsu to enhance its natural gas supply capabilities and optimize its energy structure. The roof-raising phase is the \"crucial moment\" in the construction of LNG storage tanks, featuring the most complex processes and the greatest difficulty in operation. “It mainly involves fitting the oversized roof, which has been assembled on the ground, over the tank’s walls; this is equivalent to the final roofing phase in the construction of high-rise buildings. ”Yang Xiaobing, deputy general manager of the Chemical and Natural Gas Engineering Division at China National Nuclear Fifth Corporation, explained. “To securely place this steel “cap,” which has an area equivalent to one football field and a weight comparable to that of nearly 700 passenger cars, onto a storage tank over 50 meters tall, we relied on our independently developed pneumatic jacking technology. ”Hu Kuwu, the project manager at China National Nuclear Fifth Corporation, explained, \"It can be likened to blowing up a balloon: four high-power specialized fans generate a steady stream of air, using air pressure to lift this massive structure weighing nearly a thousand tons into the air, thereby achieving precise positioning at the millimeter level.\" ” As the contractor, CNNC Fifth Engineering Company is the only enterprise within the CNNC Group that possesses the capabilities for \"integrated construction of storage tanks\" and \"integrated construction of tanks across entire plants and stations.\" It is a leading player in the field of low-temperature storage tank construction in China, and it was also the first Chinese company to bring its complete set of low-temperature storage tank construction technologies abroad. The company holds an international leadership position in terms of integrated construction capabilities for low-temperature storage tanks, and it has the expertise and experience to carry out constructions using the \"double-top lifting\" and \"triple-top lifting\" methods. The successful completion of this pneumatic jacking project for the first storage tank marks the 100th low-temperature storage tank constructed by CNNC Fifth Company. It is reported that once this project is put into operation, it will supply 4.2 billion cubic meters of natural gas per year, which accounts for 13.7% of Jiangsu Province’s annual natural gas consumption; this amount is sufficient to meet the natural gas needs of the residents in Jiangsu Province for about one month ； At the same time, it reduces carbon dioxide emissions by over 30 million tons each year, which is equivalent to planting 80 million trees. This helps to promote the development of related industries such as ports, shipping, construction, and equipment manufacturing. It also provides a stable supply of clean energy for industries like petrochemicals in the Ganyu Port Industrial Zone, thereby contributing to Lianyungang’s efforts to develop a high-value economic hub as well as green and low-carbon industrial clusters. https://www.cpnn.com.cn/news/yq/202512/W020251219525081978337.jpg https://www.cpnn.com.cn/news/yq/202512/W020251219525082827562.jpg
