Abstract

Reliability Centered Maintenance (RCM) is a methodology that aims to preserve the equipment’s functions prioritizing applicable and effective maintenance tasks, based on safety, environmental, operational and economic factors, in this order of importance. The purpose of this work is to apply the RCM in a set of specific equipment of Itaipu Binacional: the Emergency Diesel Generator Groups. Thereunto, A bibliographic review was carried out about the principles of RCM and the current maintenance systematic of Itaipu. Then, the methodology implementation study was organized in five steps: (i) system selection and information collection; (ii) Failure Mode, Effects and Criticality Analysis; iii) significant functions selection; (iv) applicable and effective tasks selection; (v) maintenance plan elaboration. The result obtained represented a proposal to change a current maintenance plan in the company by another plan, structured in the RCM concepts and with expectancy of improvement in the main maintenance indicators.
