Dear Shahid,

Find below my comments:

1. Your purpose for doing this analysis is not logical. The analysis of already failed, deformed and dislocated piping does not make any sense, Neither it can be performed correctly through CAESAR II. However, if you want to find out the root cause of problem, it makes sense. Then you have to model original piping with original isometrics and go on.

2. Giving gap in +y support, where it is not resting will also not serve the purpose as normal project based pipe support span length is much much less than CAESAR II failure results. For example, project spec says that horizontal span in 20 pipe is 12 meters. However, your CAESAR II results will show that 20" pipe will not fail even if the span becomes 35 meters.

3. I am sorry but imposed displacement in your case is entirely incorrect approach. It is normally used for equipment thermal displacement.

4. Similarly removing axial stop in between two loop will show no significant results.

Now what you have to do..

1. Do analysis as per original isometrics using CASEAR.
2. Review CAESAR II results for any failure
3. Observe the deformed support to find any difference in original isometrics and site condition.
4. Diagnose the issue , modify the iso, if required. And ask construction team to construct as per your design.
5. You may also check from your process department about probability of happening of any slug, surge, pressure fluctuation in your line.
