Abstract


The safety management is considered to be an effective way to eliminate out accident potentials and help managers adopt proper measures to improve the whole system safety level. In this regard, an integrated framework centered maintenance (SRCM) method has been proposed as a crossing strategy to improve the gas station safety performance with resort to Risk Based Inspection (RBI), Reliability Centered Maintenance (RCM) and Safety Instrument Level (SIL). It benefits from the fusion analysis of equipment risk and instrument grade. That is, we address global-scale concerns that may cause combination effect to the system performance and establish a fusion matrix to estimate the optimal maintenance strategy. An innovative logical judgment has been introduced to model the process of selecting proper maintenance measures. Meanwhile, determine the obvious failure impacts or high-risk factors. Also, Hazard and operability analysis (HAZOP) and layer of protection analysis (LOPA) have been developed to validate the SIL. The integrated framework can be also used to explain the issue of unknowns and uncertainties in reliability analysis and how these issues can be addressed in system components by optimizing component breakdown maintenance.
