..." 5 ft. or half of the diameter of the larger vessel, whichever is greater."...

Well, no, that rule results in different distances for different sizes.

Sorry but that document pertains only to LPG storage within the legal jurisdiction of the United States. You must contact the authority in your region for the correct answer, not an engineering blog. Nonetheless, the US document is a very good guide for anywhere. If your jurisdiction does not have any guidelines on LPG storage then I would follow this guide if I were you.

Please advise location of tanks.

Warnings to the local population about unsafe storage tanks must be made!!!!!!!

No, but a search engine such as Google certainly can.

Google can give out warnings to others in the vicinity of what stupid people are doing?

Cripes that's gotta eat up at least 95% of their computing resources alone.

Consult the applicable local standards and regulations as it really depends on the application, size and country.

22m is not small. Are you are working on a request for tender or something? Is this even for a fixed site or for a ship?

Some on CR4 may laugh but it wouldn't surprise me if this was for a tender proposal based on some of the previous questions from left-field we get on CR4. Potentially very dangerous.

You really need paid experts to advise you. Getting it wrong could cause serious safety and legal problems.

If you study HSE NEBOSH IOG curse, then the distances and all the other good info you require are in that course. I paid good money to take this course, to impart FOC!

The rule for within the United States of America is already given. In ISIS controlled areas, the rule is to place the tanks in intimate contact, so that when the first one goes off, they all explode.

You would have to be pretty slow to miss a conspicuous 22m LPG tank slowly being constructed on or near a sensitive site. These things are not exactly easily portable (see one of the previous "Caption this" on CR4).

Tongue in cheek!!!!

Does this mean that if one tank is 10 ft diameter and the other is 22m, then 5ft spacing is OK?

Sorry, re-read post 1 and that's clear. Can't mark this evanas off topic since it has been submitted.

I think you are spot on. Unless this on a cargo ship, where space footprint is in high demand, why put them near at all?

<...minimum safe gap...> for what eventuality? Sliding a piece of paper between them? Flying an aeroplane between them?

For legal, practical, and deemed safe storage of LPG, I thought that was clear from the thread title....doh!

Probably far enough that a lightening strike on one tank causing a flame, followed by a B.L.E.V.E. would not also set off the adjacent tank, say about 1 mile.

Why can't you interpret that from the previous installation's design documents?
