Proyecto de mejoramiento del plan de mantenimiento, empleando la técnica del mantenimiento centrado en confiabilidad de un grupo electrógeno WARTSILA VASA12V32LN y sistemas auxiliares en la planta de generación Yuralpa bloque21.

Abstract

Whit the implementation of the “Maintenance Plan Improvement Project, employing a reliance centered maintenance of the Wartsila VASA12V32LN generator group and auxiliary systems in the Yuralpa Power Plant, block 21”, located in the Chonta Punta Parish of the Napo Province, we aim to guarantee the reliance of the generating group, mitigating the recurring error modes that come about by un-programmed stops of the equipment, furthermore, its geographical location makes it more critical due to its reclusion to the Electric Petroleum System (EPS). The type of investigation used in this study is descriptive, with a documented method, the management software was based on the of the MAXIMO OIL & GAS Company and usable-life records of the equipment. The result of the application of the reliance centered maintenance (RCM), is the optimization of 79 maintenance tasks that were in the original plan of 39 focused tasks to mitigate hidden errors, which correspond to 50.63% of resource saving in space parts, labor hours and to reduce the risk of loss of crude oil production. Parting from a preliminary study of the number of errors, the critical analysis of the group is applied to the systems that conform the group, considering aspects of occurrence, exposure and consequence, determining that equipment in within the classification of Critical Asset, in a similar vein a critical analysis of the systems that conform the group is applied, establishing to the systems of: fuel, high temperature cooling, and lubrication which are found in a critical and intolerably high level. An analysis of fails and effects modes was developed (AMFE), the standardization of fail modes according to the 14224 ISO standard, critical fail mode analysis, selection of new tasks according to the SAE JA 1012 standard, duly noted in the decision files of the RCM. For which it is recommended to include new maintenance tasks in the management system in pro of assuring its compliance.
