Flow Induced Vibration (FIV), and the related problems of pulsation and Acoustic Induced Vibration (AIV), are induced by flow and pressure fluctuations in piping systems and can lead to accelerated fatigue failure if not properly identified and mitigated. In this case, our client was anticipating dead-leg pulsation, due to high multiphase flow past a dead-leg entrance, and needed to understand its magnitude, fatigue life implications, and whether it could be mitigated.
In this case we were able to confirm that despite initial assessments, pulsation was not going to cause accelerated fatigue failure, saving our customer the considerable expense of re-designing the component.
