Vibration analysis of offshore piping systems under maintenance and modification projects.

Abstract

Piping vibration failures have been one of the major causes of downtime, fatigue failures, leaks, high noise, fires and explosion in petrochemical plants. Normally excessive vibration levels occur from pulsation of mechanical source. Also, oil and gas fields in offshore have developed in more challenging environment area. According to the harsh environment, the offshore structures will face a lot of challenged in engineering and maintenance. Especially in the wave loading which has high cyclic loading so it will accumulate damage on piping system and lead to fatigue failures. In order to prevent the vibration failures we to define the majors causes of vibration failures in offshore piping systems and find the effective technical solutions to modify the piping system due to its regulations and requirements base on currently standard.
