Elaboración de un plan de mantenimiento basado en la metodología del RCM para activos críticos de la Central Hidroeléctrica de ALAO de la EERSA

Abstract

SUMMARY

The purpose of this curricular integration research was to design a maintenance plan based on the Reliability Centered Maintenance (RCM) methodology for the critical assets of the Alao Hydroelectric Power Plant of EERSA. To develop the maintenance plan, first a criticality analysis was carried out to rank the most critical assets of the power plant. After that, it was based on the detailed process of the "RCM" methodology, which consisted of performing a functional analysis of the physical asset within a current operational background, by answering 7 questions:What are the functions and operating parameters associated with the asset in its current operational context? In what way does it fail to satisfy those functions? What is the cause of each functional failure? What happens when each failure occurs? In what sense is each failure important? What can be done to prevent or predict each failure? What should be done if a suitable proactive task is not found? The information obtained by answering the first 5 questions were compiled in the RCM information sheet, while the RCM diagram and the RCM decision sheet were incorporated to answer and document the last two questions. The application of "RCM" methodology has resulted in a maintenance plan formed by 172 preventive tasks with their respective frequencies and maintenance logistics for all critical systems. It was concluded that, the "RCM" methodology allows the elaboration of successful maintenance plans, since it determines what must be done to ensure that the asset is available in its current operational context. It is recommended to implement the preventive maintenance plan designed in this work.
