Number of Course shell designed to API 650
Number of Course shell designed to API 650
(OP)
Can anyone advise how to calculate the number of course shell required in a Tank design based on the 1 foot method described in API 650?
Thanks,

A 48 foot high tank has 6 courses (6 times 8' = 48')
A 40 foot high tank has 5 courses (5 times 8' = 40')
etc.
The tank capacities are adjusted by the number of courses and the diameter of the tank.
prognosis: Lead or Lag

If it's a new tank, you consider what steel you can get. I've seen some foreign situations where the available steel was 1.5m, for example.
If it's a small tank and all the shell will be the same thickness, it won't matter in the design, and one- 32' course would be the same as eight 4' courses. If the courses differ in thickness, that's not the case.
