Reliability–Centered Maintenance Using Reliability Parameters on Gas Compressors

The main objective of reliability-centered maintenance is the cost-effectiveness of the maintenance strategy. These strategies, rather than the different components of reliability-centered maintenance being applied independently, are optimally integrated to take advantage of their respective strengths to optimize equipment reliability and life-cycle costs. The article uses reliability parameters to define the type of maintenance strategy and time to perform maintenance on gas compressors. This article presents a methodology using the gas compressor's reliability parameters to model reliability-centered maintenance procedure for the gas compressors. The approach is based on reliability parameters gotten from the liner regression carried out on the gas compressors. The shape parameter (β) from the Weibull linear regression shows that most components in the two gas compressors were experiencing early failure with their β < 1 and the distribution that best fits the data is the lognormal distribution, whose parameters are the shape parameter (σ') and the scale parameter (µ').
