AIV/FIV Screening of a High-Pressure Gas Piping System
Screening small-bore connections downstream of a pressure-letdown station and closing a resonance risk with targeted reinforcement.
01 — ChallengeUnscreened small-bore connections near a letdown station
Piping downstream of a pressure-letdown station had not been screened for Acoustic-Induced Vibration (AIV) or Flow-Induced Vibration (FIV) risk against Energy Institute guidelines, leaving an unknown fatigue exposure at small-bore connections.
02 — ApproachCombined acoustic screening and modal FEA
Acoustic power level screening per EI guidelines identified high-risk connections, which were then carried into modal FEA to check natural frequency against the excitation band from compressor harmonics.

04 — Quantified ResultsBefore / After
| Parameter | Baseline | Result | |
|---|---|---|---|
| Connections in “high likelihood of failure” zone | 4 identified | → | 0 after reinforcement |
| Natural frequency vs. excitation band | within 15% | → | +38% shifted clear |
| Fatigue life at critical weld | <2 years | → | >20 years |
05 — Business Impact
Prevented a probable high-cycle fatigue failure of a type that causes unplanned shutdowns in comparable systems.
