Abstract

A condition monitoring system for a pressure vessel includes at least one vibration monitoring probe coupled to at least one pressure vessel component. The system also includes at least one computing device that includes a memory device configured to store data associated with the at least one vibration monitoring probe. The computing device also includes at least one input channel configured to receive the data associated with the at least one vibration monitoring probe. The computing device further includes a processor coupled to the memory device and the at least one input channel. The processor is programmed to determine a deterioration of the material condition of the at least one pressure vessel component by comparing at least a portion of the data associated with the at least one vibration monitoring probe with predetermined vibration parameters.
