Modeling Effective Maintenance Strategy using Reliability Centered Maintenance with Risk Maintenance

Abstract

This study was done with the aim of modeling effective maintenance strategy using reliability centered maintenance with risk maintenance. The primary data obtained were analyzed partly in the MS excel and MATLAB computational environment in line with the modeled equations of reliabilityand maintainability condition of a selected rotodynamic system (pump) of a selected petrochemical firm in Rivers State. The maintenance strategies were selected from scheduled maintenance (SM), condition-based maintenance (CbM), Proactive Maintenance (PrM) and design-out modification (DoM) maintenance alternatives. The analyses for ranking of the maintenancealternatives for eachcomponent of the pump showed that, the best alternative for
bearing is scheduled maintenance (SM), the best alternative maintenance strategy for impeller condition-based maintenance (CbM), the best maintenance alternative strategy for mechanical seal is proactive maintenance (PrM), and the best maintenance strategy for shaft is proactive maintenance (PrM).
