In recent days, outside the Erdaogang area of the Lingang Industrial Zone in Yangkou Port Economic Development Zone, the construction workers of the Jiangsu Coastal Gas Pipeline Project have been working hard to carry out backfilling operations. About 2 meters underground, a huge pipeline can be faintly seen. The diameter of this pipeline is 1,219 millimeters. If the eastern section is laid, it will be 48 kilometers long. At present, the project of this section has been basically completed and is about to be completed. Project Manager Ding Feng told reporters that in the future, the natural gas on the energy island can be transported to the first station in Rudong through pipeline bridge channels. After pressure regulation, it can be sent to various places in the Yangtze River Delta. Under full load conditions, the daily transmission volume can reach 90 million cubic meters, equivalent to the annual gas consumption of 450,000 households.
The Rudong-Changshu-Taicang section of the Jiangsu Coastal Gas Pipeline Project is an important part of the coastal pipeline network trunk line in the Jiangsu Province Coastal Gas Pipeline Special Planning, and it is an important channel for the transportation of LNG gas sources from Rudong, the "energy island", to Changshu, Taicang and other places. Energy Island is currently the largest LNG unloading and transfer base in the Yangtze River Delta region. The China National Petroleum Corporation Jiangsu LNG Receiving Station on the island has built and put into operation six LNG storage tanks, with a total tank capacity of 1.08 million cubic meters and an annual turnover capacity of over 7 million tons. Meanwhile, the Jiangsu Province Liquefied Natural Gas Storage, Transportation and Peak Shaving Project, which started construction in 2020, will build four LNG storage tanks. Once fully operational, the annual unloading and turnover capacity will reach 6 million tons. In addition, the GCL Huidong LNG receiving terminal and the China Resources LNG Receiving Terminal, which have already been located on the island, are also accelerating their preparatory work. After the completion of all four major energy projects, the annual turnover capacity of the entire energy island will exceed 20 million tons.
"The current pipelines are unable to support such a large-scale natural gas transportation. The coastal gas pipeline project in Jiangsu Province is imperative." " Ding Feng told the reporter that as the earliest section to start construction, the Rudong-Changshu-Taicang section has completed welding for 80 kilometers so far, and the Yangtze River shield machine has also advanced for 8 kilometers. This section starts from Sunshine Island in Yangkou Port, lands on the pipeline bridge of the land-island channel in Yangkou Port Area, and then extends southwestward towards the Tongzhou Bay River-Sea Linkage Development Demonstration Zone and Haimen. After crossing the river at Jiangxinsha Farm in Haimen, The terminal stations are Dongbang Distribution Station (Changshu) and Huangjing Distribution Station (Taicang) of Jiangsu Natural Gas Company, with a total pipeline length of 170.8 kilometers and a total investment of approximately 5.34 billion yuan. After the project is completed, it will connect multiple LNG receiving terminals and several gas pipelines along the coast, and be interconnected with the national pipeline network's China-Russia East Line Yongqing-Shanghai, West Line 1 and West Line 2 Shanghai Branch Line. It will also take into account the gas transmission demands of surrounding provinces, achieving intensive utilization of land resources and routing resources.
At present, Rudong First Station, which serves as the starting point of the trunk line, is also in the process of accelerating its approval application and is expected to be ready for construction by the end of this year. The Rudong-Changshu-Taicang section is expected to be put into operation in December 2024. Once the entire line is connected, it will significantly optimize the layout of the natural gas industry in Jiangsu Province, alleviate the supply and demand contradiction of natural gas in central and northern Jiangsu, strengthen the pipeline storage and transportation infrastructure, improve the energy transmission environment in the Yangtze River Delta region, and further enhance the emergency guarantee capacity of the natural gas pipeline network in this region.
