Abstract

This research implements Risk Based Inspection (RBI) as an analytical method to perform risk assessment to gas dryer instrument. The risk assessment is performed by determining the probability of failure and consequence of failure from gas dryer instrument. The risk level can be determined by mapping the risk onto risk matrix. The damage factors identified to occur in gas dryer instrument are internal thinning and external corrosion. The probability of failure is found to be 3.51 x 10-6 failure/year, which fall under category 1. While the consequence are of failure was found to be 5,056.88 ft2, which fall under category C. Therefore the risk level posses by gas dryer instrument was found to be 1C. The remaining life of the instrument gas dryer is expected to be 243.5 years. The risk Is expected to reach the risk target after 27 years of operation.
