Morning KP

my understanding is:

1/ to assess a tank , AN EXISTING tank I mean you use appendix B of API 653

2/ to assess the piping stress, the supports ( where you might need spring supports, to assess the loads on the tank nozzles..then you have to conduct pipe stress studies with Caesar or something similar ..and include the settlement in the loads
Stress according to B31.3
Tank nozzle loads according to appendix P of API 650 ..Which is already implemented in Caesar

Well, my opinions only ..probaly someone can correct or confirm

thanks to all
