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]

Core Viewpoint - The Jiangsu Huadian Ganyu LNG receiving station project, a key national natural gas infrastructure initiative, has completed the pressure topping operation of its first storage tank, enhancing regional gas supply flexibility and reliability while optimizing the energy structure in the Yangtze River Delta [1][2][3] Group 1: Project Overview - The project is located in the Ganyu Port area of Lianyungang, Jiangsu, and is the first land reclamation project approved since the establishment of the Ministry of Natural Resources, as well as the first subsea gas pipeline project in Jiangsu [1][2] - The project plans to construct three LNG storage tanks, each with a capacity of 220,000 cubic meters, and is a strategic layout for enhancing natural gas security and optimizing energy structure in Jiangsu [1][2] Group 2: Construction and Capabilities - The construction is undertaken by China Nuclear Engineering Group's subsidiary, CNNC No. 5 Company, which is the only enterprise in the group capable of integrated construction and installation of storage tanks and has leading capabilities in low-temperature storage tank construction in China [1][3] - CNNC No. 5 Company has achieved significant milestones, including being the first in China to export complete low-temperature storage tank construction technology and completing its 100th low-temperature storage tank with this project [3] Group 3: Environmental and Economic Impact - Upon completion, the project is expected to supply 4.2 billion cubic meters of natural gas annually, which accounts for 13.7% of Jiangsu's annual natural gas consumption, sufficient to meet the monthly gas needs of approximately one month for Jiangsu residents [2][3] - The project will also reduce carbon dioxide emissions by over 30 million tons annually, equivalent to planting 80 million trees, and will stimulate the development of upstream and downstream industries such as ports, shipping, engineering construction, and equipment manufacturing [2][3]
