Propuesta de implementación del mantenimiento centrado en la confiabilidad para los turbocargadores ABB VTR 354, usados en los motores WARTSILA VASA 16V32 L.N. de la empresa AGIP OIL Ecuador

Abstract

It is Reliability Centered Maintenance (RCM) for turbochargers ABB VTR 354, used in the V32 engines Wärtsilä VASA 16 LN of Company Agip Oil Ecuador, which is located in the province of Pastaza, in block 10; due to demand of electric energy for operation of the equipment required for transport, treatment and pumping of oil, Wärtsilä engines are about a reliability over 96% and an availability over 98%; These key performance indicators are set by the company and the manufacturer; However, in the study period, between 2011 and 2014, the indices of performance engines were of 94% of reliability and 97% of availability, which caused production and economic losses for the company. Applying the methodology of Reliability Centered Maintenance for turbochargers ABB VTR 354, which are used to repower engines, a new maintenance plan was proposed, the same being applied to equipment with the current operational context, improving equipment performance, reliability over 97% was increased and the availability over 98.5% of the engines, it extends the useful live of the equipment, the probability of failure is minimized and avoid its consequences, it increased safety and environmental integrity. This methodology is technically feasible because the cost of implementation is less than the cost of lost production that represents the functional equipment failure; it recommends following the Plan of Reliability Centered Maintenance proposed and evaluate the results, so to present it as a pilot program for critical equipment company.
