Dear experts,

I would like to do dynamic analysis in CAESAR II, here few types of dynamic analysis are available in CAESAR II, Like model, earthquake, relief, water hammer, harmonic and time history analysis,

The line size is 12 inch and it is connected with the heat exchangers, the line service is liquid only, here we have control valve (ball valve) for flashing perpose,also we have two gate valves, one is before control valve another one is after control valve, the 12 inch line is getting high vibration this vibration is transferred to structure, it is also vibrating.

Kindly advise me which dynamic analysis is suitable for this kind of problem.

How to retify the above problem,

This line has sufficient pipe supports, I guess there is no issue on support point of view. Total 7 meters pipe length we have 3 nos. Of supports are already available.

And also Here no two phase flow, no pump and no compressor, Here I guess this is purely flow induced vibration only.
