[Haichuan Chemical Salary News] Approval granted for 10 LNG storage tanks with a capacity of 200,000 cubic meters for the Tianjin Nangang LNG emergency reserve project

The project will be constructed in three phases. The first phase will establish a preliminary emergency supply system, including 1 LNG unloading terminal, 1 LNG vessel berth, 4 storage tanks as well as gasification facilities and loading infrastructure; the pipelines leading to Beijing will be fully completed, with the goal of finishing construction by the end of 2022； The second phase involves the construction of 4 storage tanks, with the goal of completing the work by the end of 2023 ； The third phase involves the construction of 2 storage tanks, with the goal of completing the work by the end of 2024. Beijing Gas plans to establish an independent company to be responsible for the investment, construction, and operation of the Tianjin Nangang LNG project. By providing services such as unloading, storage, gasification, loading, and transportation of gas, the company will charge fees for gasification, liquid processing, and pipeline transportation, in order to cover the total costs and taxes and achieve a reasonable return on investment.

The total investment amount for the project is 20.13 billion yuan, of which 19.26 billion yuan is allocated to construction costs, 840 million yuan to interest during the construction period, and 30 million yuan to working capital. Beijing ** will provide 30% (RMB 5.78 billion) in grant funds free of charge for the project construction. Beijing Gas plans to raise the funds required for the construction of the Tianjin Nangang LNG project through its own capital and low-interest loans from financial institutions. Based on Beijing’s functional positioning for this project, as well as the promised price adjustment mechanism and the subsidy policy for the cost difference in LNG procurement, Beijing Gas can achieve a reasonable return on investment under the emergency supply guarantee framework, thereby meeting its requirements regarding investment returns.

The Nangang Industrial Zone is part of Tianjin’s \"Dual Cities, Dual Ports\" urban spatial development strategy; it is located in the southeastern part of the Binhai New Area, 45 kilometers away from the downtown area of Tianjin, 40 kilometers from Tianjin Airport, and 20 kilometers from Tianjin Port. The industrial zone is structured as \"one area, one belt, and five parks,\" featuring a favorable ecological environment, complete infrastructure, and an excellent investment climate. Faced with the new circumstances, the development zone will further implement the scientific outlook on development, uphold the spirit of \"pioneering innovation for continuous progress and striving for excellence to achieve greatness,\" and work hard to turn it into an important platform for driving the city’s economic development and its primary engine of growth.

It was learned from the Tianjin Development Zone that as of now, major projects in the Nangang Industrial Zone such as Zhongsha, Huadian, BoHua VCM, BoHua Utility Support, Beijing Gas, Sinopec’s LNG Phase II, and Huntsman have all resumed operations. This year is a critical period in the construction timelines of major projects such as Nangang’s integration of industry and information technology, the Zhongsha project, and Huadian’s projects. To succeed in the fight against the epidemic, starting from New Year’s Eve, a comprehensive inspection was carried out on 47 construction projects in the Nangang industrial area, involving a total of 1,042 people. Special attention was paid to those who entered the area daily, in order to prevent the spread of the epidemic and ensure that isolation requirements were properly followed. In mid-February, the Nangang Construction Services Center took the lead in drafting the \"Guidelines for Resuming Construction Work in the Nangang Industrial Zone.\" It provided on-site guidance for resuming projects, arranged accommodation for construction workers, and helped establish isolation points for construction sites, thereby giving businesses peace of mind. As the provider of heat, electricity, and steam for the Nangang Industrial Zone, the construction timeline of the Huadian project directly determines whether other major projects can be put into operation on schedule. “How many workers will arrive tomorrow, and is further isolation required? Is the isolation area ready? ”Qiu Shengming, the grid officer for this project, asked in detail. The Bohua VCM project is the starting point of the industrial chain for these relocation projects; it has the tightest schedule and faces the greatest pressure to resume operations. Meng Jingbo, the officer in charge of this project, visits the VCM site every day to oversee the resumption of work: “How much epidemic prevention supplies have been prepared?” How many days will the masks last? How many people live in one room of the staff dormitory? You can’t have everyone eat together in the cafeteria” ； The Zhongsha project was originally scheduled to go into operation by the end of this year. Since the project did not have a residential area, employees returning from other places could not find a place to live. Lei Yutian, the project’s grid manager, took immediate action and secured accommodation and isolation facilities for the Zhongsha project by using apartments in the central area.

Big move! It can be considered a strategic reserve project; if we take advantage of this drop in crude oil prices, we’ll make a huge profit. But it’s not too late to start building it now.

This project is indeed quite large; typical LNG storage tanks come in quantities of two or four, while this one has ten – making it a super-project. Moreover, the 200,000-cubic-meter cryogenic tank is also the largest of its kind

According to available information, this has been localized in China. ========================= On November 3, 2016, in Nantong, Jiangsu, an aerial view showed the T-1204 storage tank – the largest single-tank LNG storage tank in China with a capacity of 200,000 cubic meters (gray in color) – which was successfully put into operation for the first time. The storage tank is a full-volume concrete tank; it is the largest LNG storage tank in China to be independently designed and constructed. The total weight of the tank body is 165,000 tons, with a nominal volume of 223,000 cubic meters and an effective storage capacity of 200,000 cubic meters. On November 3, 2016, in Nantong, Jiangsu, China’s first LNG storage tank with a capacity of 200,000 cubic meters—the T-1204 tank as part of the Jiangsu LNG Phase II project—began to receive liquid and was put into operation successfully on the first attempt. This marks the full completion and commissioning of Jiangsu LNG Phase II project, which is of great significance for the gas supply for production and daily use in the Yangtze River Delta region, the stable operation of the West-to-East Gas Transmission pipeline network, as well as the development of China National Petroleum Corporation’s offshore strategic transportation routes. According to Tang Kai, deputy general manager of CNPC Jiangsu LNG Co., Ltd., the second phase of Jiangsu’s LNG project began construction in September 2013. The T-1204 storage tank in this second-phase project is a full-volume concrete tank; it is currently the largest LNG storage tank of its kind in China. The total weight of this tank is 165,000 tons, with a nominal volume of 223,000 cubic meters and an effective working volume of 200,000 cubic meters. The storage tank is equipped with a floor-mounted electric heat tracing base; the cylindrical concrete outer tank has a diameter of 86.4 meters and a height of 44.2 meters ； The inner tank has a diameter of 84.2 meters and is made of domestically produced Ni9 steel and low-temperature insulation materials ； The tank roof is a circular arch-shaped steel structure; the center of the roof is 56 meters above the bottom surface inside the tank, and its weight is approximately 1,000 tons. To put it vividly, a large A380 aircraft with a length of 76 meters can be easily fitted inside the tank. Phase 1 came online in May 2011, with 3 LNG storage tanks with a capacity of 160,000 cubic meters each being built, as well as a dedicated terminal capable of handling LNG ships with a capacity of 125,000 to 267,000 cubic meters. To date, the receiving station has unloaded LNG from 127 ships, totaling 11.6 million tons, and has exported over 16 billion cubic meters of natural gas. After the commissioning of the second phase, the total storage capacity of the 4 tanks at the Jiangsu LNG receiving station reaches 680,000 cubic meters ； The unloading capacity reaches 6.5 million tons per year ； The gasification capacity reaches 10 million tons per year ； The normal gas transmission capacity ensures 30 million cubic meters per day, while the maximum daily transmission capacity can reach 40 million cubic meters per day. In addition to innovative design and construction, the storage tank features domestically produced construction technologies and materials, thereby establishing its own intellectual property rights. The company has actively promoted the independent research, development, and construction of large-scale LNG storage tanks, as well as the research and application of domestic production for ORVs (open-type vaporizers) and SCVs (immersed combustion vaporizers). In close collaboration with the EPC contractor China Global Engineering Corporation, it initiated research on LNG storage tank construction technologies in 2012. Key technical challenges were overcome, including those related to the stability calculation of the steel reticulated shell on the top of large storage tanks during construction, numerical simulation of the stability of concrete outer tanks under abnormal load conditions, and stability simulation calculations under static and seismic load conditions for the inner tanks. Both the tank construction technologies and materials were made domestically produced, resulting in the creation of proprietary intellectual property rights ； By collaborating with relevant research institutions and manufacturers, China’s first set of SCV gasifiers was developed, featuring the application of four key technologies such as \"U-shaped turbulent heat exchange flow field stability technology\" and \"double-helix burner structure design technology\" ； The organization overcame four major challenges related to China’s first fully domestically produced large-scale ORV open-type vaporizer: the design and manufacturing technology for aluminum alloy finned tubes optimized for efficient heat transfer in low-temperature two-phase flow, the low-energy welding technology for low-temperature tube bundles, and the technology for preparing composite joints for tube bundles. These solutions were successfully applied and passed relevant evaluations, thereby breaking the technical monopoly held by foreign companies.
