For the first time in the world!The three largest LNG storage pots in the world are rising simultaneously in Binhai Port

"3, 2, 1, start!" At 9:20 on September 7, in the Yanyan Binhai Port Industrial Park of Yellow Sea, 3 single -seater area of ​​about 1 standard football field and LNG (LPG natural gas weighing nearly 1,200 tons (liquefied natural gas ) Storage tank dome began to rise to 60 meters high through air pressure. This is the first time in the world's 370,000 cubic meters of LNG LNG storage tanks synchronized, marking my country's oversized LNG storage tank design and construction technology and project management to the world -class level.

China Sea Oil Yancheng "Green Port" is the largest LNG receiving station project in the world's largest construction scale. The first phase of the project started on June 9, 2021 Constructed 4 220,000 cubic meters of storage tanks and 6 largest in the world. 270,000 cubic meters of tanks, a total of 2.5 million cubic meters.

The top -top is the one with the most technical difficulty and the highest safety factor requirements during the construction of the storage tank. Compared with the previous 220,000 cubic meters of storage tanks, the weight of the dome increased by 20%, and the area increased by nearly 1,000 square meters, and the three storage tanks rose simultaneously. High requirements.

According to Li Deqiang, deputy commander of the "Green Port" project of China Sea Oil Yancheng "Green Port" project, technicians through the four major systems of balanced orientation, storage tank sealing, littering power and intelligent monitoring, in real time monitoring and accurate control of storage tanks when the top of the tank is raised. Parameters such as air pressure, rate, offset degree to ensure the safety and stability of the gas ascending. The entire process of raising the dome, the dome rotation deviation does not exceed 0.12 degrees, and the horizontal offset does not exceed 7 %, which fully meets international standards. As the core equipment of the LNG industry chain, the LNG storage tank is costly costly, with high requirements for safety, and the design and construction process is very complicated. It is one of the cutting -edge technologies in the energy field.

Li Feng, deputy chief engineer of China Haiyou Gas and Electricity Group and the party secretary and general manager of Jiangsu LNG, said that the design and construction of 270,000 cubic meters of LNG storage tank overcome the stable analysis of large span thin -shell structure, ultra -high shear wall seismic design, and flexible piles. Restriction of carrier capacity calculations and other problems. The successful rise of the three storage tanks this time not only proves that my country's oversized LNG storage tank design and construction technology has reached the world -class level, but also accumulated rich experience for the large -scale and massive construction of the LNG storage tank.

China Sea Oil Yancheng "Green Port" is a national natural gas production supply and storage system construction and interconnection key planning project. After all commissioning and operation at the end of 2023, the LNG annual processing capacity will reach 6 million tons, which is equivalent to 8.5 billion cubic meters of gas and natural gas 8.5 billion cubic meters. It can be for about 28 months for people's livelihood for people's livelihood.

"The Yellow Sea here has become a blue ocean, and 100,000 tons of freight ships can be directly entered." Xu Bin, deputy secretary of the party committee of Jiangsu LNG, said that the port dredging project as an important single project in the construction of the "Green Port" project of Yancheng The construction period is nearly 9 months, mainly for nearly 820,000 square meters of port pools, 1168 meters into port channels, and 3827 meters of main channels. 1.2 times. There are many difficulties in the construction of the project, the difficulty of dredging, poor excavation, poor natural conditions, and severe recovery. The transportation distance is 15 kilometers. It is the longest dredging project of domestic single -shipping spacing. To this end, the project department has invested in several large flagship muddy ship represented by the "Hao Hai Long" wheel and the "Hang Jun 6008" wheel. At present, it marks that the current port ponds and main channels of China's "Green Port" Port in China Oil Salt City have met the world's largest 270,000 cubic meters of LNG transport ships.

"Successful!" At 10:48, Yang Yong, deputy general manager of China Oil and Electricity Group, announced the results of the construction. He told reporters that the first LNG outer wheel on September 26 will enter Binhai Port, China Oil Yancheng "Green Green "Energy Port" will be officially put into production. According to Yang Yong, China Oil is actively promoting the planning and construction of large, large LNG storage tanks. Zhuhai, Ningbo and other places also have 1170,000 cubic meters of storage tanks are under construction. Wanli -cubic meter storage tank is also accelerating the preliminary work. It is estimated that by the end of 2025, the new LNG reserve capacity will be 5.67 million cubic meters, which is equivalent to reaching a gaseous and natural gas of more than 3.5 billion cubic meters, which can further enhance my country's natural gas emergency supply capacity and contribute to the "sea oil power" to ensure national energy security.
