For achieving sustained equipment reliability in the long term, and minimizing the potential for unplanned shut-downs, well defined Preventive Maintenance (PM) and Predictive Maintenance (PdM) are a recommended industry practice. The efficacy of these programs is greatly dependent upon identifying critical equipment in Process Units, and establishing, reliability and conditioning monitoring, and operator surveillance programs. Work Practices for establishing these programs need to be established in a cost-effective manner and periodic stewardship of PM compliance is needed. The use of state-of-the-art technology for online equipment health monitoring is a major consideration when maximizing the reliability performance of critical equipment. Becht's Knowledge Based Resources have the expertise to develop and implement such programs.
