Seek a design example for a 150,000 cubic meter crude oil storage tank

A 150,000 cubic meter storage tank that has been built in a certain location in the country has an inner diameter of 100 meters and a wall height of 21.8 meters; it features a double-disk structure. Its net weight is 2,800 tons. The steel plates used in the critical parts are imported SPV490Q steel plates, while the rest are made from domestic Q235-B material. The oil tank is equipped with a weight-type wax-scraping mechanism.

A friend upstairs needs ready-made examples; thanks for continuing to post.

150,000 cubic meters? That’s amazing. If anyone has such information, it’s also a trade secret.

The requirements are not high; I just hope to see a rough calculation process, preferably one based on API650. Thanks for continuing to post!

China’s first enterprise standard for large storage tanks, jointly developed by China University of Petroleum, was released 2009-4-6 10:16:54 【News from our site】Recently, the first domestic set of guidelines for the design of steel welded floating roof oil tanks with a capacity of 100,000 to 150,000 cubic meters, which were developed jointly by the School of Storage, Transportation and Construction Engineering at China University of Petroleum (East China) and the Science and Technology Engineering Company of China National Petroleum Corporation’s Changqing Oilfield, passed expert review. The review experts unanimously agreed that these design specifications fill the gap in the design standards for steel floating roof oil tanks with a capacity of 100,000 to 150,000 cubic meters, both domestically and internationally, and hold guiding significance and great reference value for the optimized design of large-scale storage tank projects in China. 　　According to experts, there have been no unified design standards for large steel floating roof oil tanks with a capacity of 100,000 to 150,000 cubic meters, both domestically and internationally. In May 2008, the Science and Technology Engineering Company of China National Petroleum Corporation’s Changqing Oilfield commissioned China University of Petroleum (Huadong) to carry out research on a technical development project for the structural safety optimization design of large floating roof oil tanks. Taking into account the construction of oil tanks with a capacity of 100,000 to 150,000 cubic meters in China, the research team began by examining the particularities and complexities associated with the design of large-scale storage tanks, and conducted a comprehensive and in-depth study of the standards, materials, structure, and safety aspects of such large floating roof tanks. Following 10 months of in-depth research, the design specifications for steel welded floating roof oil tanks with a capacity of 100,000 to 150,000 cubic meters were established. 　　After review, the evaluation expert group concluded that the \"Design Specifications for Steel Welded Floating Roof Oil Tanks with a Capacity of 100,000 to 150,000 Cubic Meters\" features a reasonable overall framework, comprehensive content, correct calculation formulas, and clear organization. The design methods for such tanks, along with the corresponding requirements for manufacturing and inspection, are clearly defined. Additionally, specification dimensions for three types of large-scale tanks – with capacities of 100,000 cubic meters, 125,000 cubic meters, and 150,000 cubic meters – have been established; this represents the first enterprise standard of its kind for large-scale oil tanks in China.

Could you be more specific about the information on floor 6? What are the relevant standards, and when will it be published?

There are no real-world examples, but you can refer to books such as \"Design of Tank Structures\" and \"Design and Management of Oil Depots\". These were our textbooks during university, and they contain information related to the design of oil tanks. The knowledge in them is sufficient to help you design a 150,000-gallon oil tank. If it were a real-world case, you would need to take into account differences between the north and south, the different types of substances used, wind conditions, and many other factors. . . So I suggest you refer to books instead. .

To date, Daqing has completed the construction of two storage tanks with a capacity of 150,000 cubic meters, and eight more are under construction. However, the first two tanks have some defects, mainly related to errors in the stress analysis of their outer shell plates. The specific calculation process is still kept confidential at this stage and cannot be disclosed.
