Mejoramiento del plan de mantenimiento en las unidades móviles de prueba en la Empresa SERTECPET S.A. aplicando la metodología de la optimización del plan de mantenimiento

Abstract

The objective of this technical project was to improve the maintenance plan in the mobile test units (MTU), at SERTECPET S. A. company, located in Puerto Francisco de Orellana canton, (El Coca), applying the Maintenance Plan Optimization (PMO) methodology. During the initial stage the maintenance area was evaluated by means of the "Maintenance Effectiveness Survey (EEM)", which was applied to the maintenance personnel and obtained a score of 225.38/300 points, which determines that the maintenance area at SERTECPET S.A. Company, is in a category of good maintenance practice level. For the maintenance plan improvement was applied the PMO methodology that contains 9 steps. The collection of maintenance tasks was carried out, then the failure modes were defined, debugging and coding of failures, evaluation of the failure consequences, maintenance tasks definitions, and finally approval and implementation of this information. In addition, the tasks were grouped according to their frequency to facilitate the information obtained. Then, maintenance resources were defined, such as spare parts, materials, tools and personnel, for the proper execution of maintenance activities corresponding to logistics. During the final stage, training was conducted on the applied methodology, generating new knowledge and skills in the company's personnel. It is concluded that through the application of the (PMO), duplicity in certain tasks within the current maintenance plan was reduced by 16% and new failure modes were also taken into account. It is recommended to perform timely periodic evaluations of the effectiveness and efficiencies of the maintenance tasks.
