Dear members,
A problem has come up about the vibration of a 48", 600# LNG export pipeline and a connected 24" line near the pig launcher . It has been found that if the flow rate is increased, there is severe vibration on this branch line, and it is reduced if the flow rates decrease. How to simulate this kind of problem of flow induced vibration in Caesar-II.

The compressor driving the flow is about 200m away and is connected to this system by underground lines. Therefore, I think the transmission of the compressor induced vibration is not a contributing factor towards the vibration problem.
