Yancheng, Jiangsu: 3 largest LNG storage tanks in the world in the Yellow Sea New Area

On September 7th, in the Binhai New District of Yellow Sea New District, Yancheng City, Jiangsu Province, three single -seater area of ​​about 1 standard football field and LNG (liquefied natural gas) storage tank dome rose to a 60 -meter -high tank roof through air pressure to 60 meters high. 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 reach 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 will build a total of 220,000 cubic meters of storage tanks and 6 largest 270,000 cubic meters of storage tanks in the world. 2.5 million cubic meters.

This time the tank dome 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 in 10,000, 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 Sea Oil Vitamin Group and the head of Yancheng "Green Port" project, said that the design and construction of 270,000 cubic meters of LNG storage tank overcome the stability analysis of large span thin -shell structure, ultra -high shear wall seismic design, and seismic design, and super high shear wall shock anti -earthquake design, Flexible constraints and carrier capacity calculation of piles. 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.

Yang Yong, deputy general manager of China Sea Oil and Electricity Group, said that China Sea 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. Yancheng "Green Green The 270,000 cubic meter storage tanks in the second phase of the "Phase of the Port" are 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.
