Oil storage tank design 1

[The Egyptian lady]

Good day everyone, i need your support in designing oil storage tank 500m3, i was asked to design it half buried. The area we will build it not in earthquake line, any ideas about height, diameter and shell thickness??

You need to know what code you are working to. There are rules for these things.

Atmospheric tanks shall be built in accordance with acceptable good standards of design. Atmospheric tanks may be built in accordance with:

1926.152(i)(1)(iii)(A)(1)
Underwriters' Laboratories, Inc., Subjects No. 142, Standard for Steel Aboveground Tanks for Flammable and Combustible Liquids, 1968; No. 58, Standard for Steel Underground Tanks for Flammable and Combustible Liquids, Fifth Edition, December 1961; or No. 80, Standard for Steel Inside tanks for Oil-Burner Fuel, September 1963.

American Petroleum Institute Standards No. 12A, Specification for Oil Storage Tanks with Riveted Shells, Seventh Edition, September 1951, or No. 650, Welded Steel Tanks for Oil Storage, Third Edition, 1966.

1926.152(i)(1)(iii)(A)(3)
American Petroleum Institute Standards No. 12B, Specification for Bolted Production Tanks, Eleventh Edition, May 1958, and Supplement 1, March 1962; No. 12D, Specification for Large Welded Production Tanks, Seventh Edition, August 1957; or No. 12F, Specification for Small Welded Production Tanks, Fifth Edition, March 1961. Tanks built in accordance with these standards shall be used only as production tanks for storage of crude petroleum in oil-producing areas.

I was asked to design the tank as per API 650. My manager asked me to design it half buried, she prefer to use ST44

I am guessing here that you have been assigned a task on a topic the you know nothing about.

Based on the elementary nature of your questions, I assume that there is no one in your organization to which you can ask questions

There are several good books, papers and forums available to educate yourself on API-650, vertical axis, flat bottomed tank design. These fora contain the accumulation of years of experience from grizzled veterans of tank design.

This is a good place to start .... Buy this book

https://www.amazon.com/Above-Ground-Storage-Tanks-Philip/dp/007044272X

Some important questions that must be answered before an API-650 tank can be designed are:

1) Exact nature of liquids stored including flammability, vapor pressure, design temperatures etc
2) Exact details about foundations, soil conditions and preferred bolting design
3) Venting/ pumpout requirements
4) Seismic/Wind loading conditions, minimum site temperature
5) Your preferred coatings systems
6) Your access requirements to the top and interior of the tank

etc ... etc....

Tell us more about your bizarre requirement for a half buried API-650 tank ...

The manager seems to have changed his mind...errr, I am wrong.
What I mean is, the manager is definitely a 'he'.

Height and diameter of the tank are usually determined by the function of intend use, storage volume, and location and space constrain. Once these parameters are set, you can estimate plate thickness through code provisions.

Egypt,

Anything happening with your tank design ?

...or have you lost interest ?
