Análisis de confiabilidad a la turbina de generación eléctrica lm 2500 ubicada en el campo NPF de la Empresa Repsol Ecuador para establecer un plan de mantenimiento.

Abstract

This paper analyzes the fault occurred in the power generation turbines for the development of reliability teams held in the company REPSOL ECUADOR. a collection of failures occurred in the years 2014 2015 turbines in block 16 North REPSOL field (NPF) was performed. These failures were classified according to the systems which they operate, and so had three systems: fuel system, cooling system and lubrication system. Each one of these systems was performed an analysis of reliability that is encode its elements, define their functions, determine their faults, determine their failure modes, perform a criticality of systems and times established in which they have occurred each of these failures through the calculation of mean time between failures. An analysis was also conducted to determine production losses that had in the years analyzed and economically as has represented the occurrence of failures for both the cost of corrective maintenance as well as for the cost of lost production. With the application of engineering failures are reduced driveability bringing reduced production losses. Once you have the average time between failures applying these in the maintenance program of the company reduces corrective maintenance and this is achieved by increasing the production of barrels of oil. In 2014-2015 22 faults with power cut they took 319 hours, lower production losses of 62,173 barrels to 34,029 barrels analysis.
