With respect, your client appears to be an idiot to give the design of such a vessel to a company which has never done it before. That list is basically all the design aspects you need to look at and you're coming onto an internet forum to find it out??

I suggest you subcontract this to a suitably experienced and qualified company and then try and learn some key items from them.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

LittleInch is, as always, correct.

It appears that neither you or your client have any experience with Horton spheres or LPG storage.

Most LPG storage tanks are NOT Horton spheres ...... This should tell you something.

At least your smart enough to know that you don't know. That is a HUGE mark of intelligence, but you should sub this out to an experienced company and try to learn from them.

Since Horton spheres are design in accordance to ASME pressure vessels according to manufacturers listed on the internet, The National Board may have in their archives information pertaining to some of your inquiries and the ASME pressure vessel code would be an additional resources dealing with the construction of such sphere.
