Abstract—In this study, the sound power level of the gas piping system was determined at the sources of vibration and at each discontinuity using the criteria of sound power level limit curves and the Likelihood of Failure (LOF). A detailed finite element model of the connection was developed, and a random acoustic field equivalent to the acoustic power level calculated by generating and applying a pressure field on the walls and summing up the stresses resulting from excitations. This study would help minimise or avoid physical pipe modification, reducing the offshore plant shutdown time while enhancing the safety of the plant. Also, modifications such as alteration in pipe size (diameter and thickness) should be implemented to reduce the Acoustic Induced Vibration (AIV) effects to an acceptable level.
