Gestión del mantenimiento de cables subterráneos de media tensión en el sistema eléctrico del Bloque 31 operado por Petroamazonas EP.

Abstract

The medium-voltage underground cable maintenance management system in Block 31, was developed in Orellana province, Aguarico canton. This investigation was exploratory and descriptive. We know this system is used to distribute electrical energy in the most of oil enterprises, that is why it is important to manage its maintenance efficiently to extend its lifespan without affecting the surroundings and to ensure the staff. In this investigation, we used preventive and predictive techniques of our environment. Internal audit and survey were also considered to determine the current maintenance situation. A level of effectiveness of 43% was gotten, but it was no acceptable. The impact of a failure in the system was evaluated. Some alternatives were set out to manage its maintenance by means of a maintenance plan and in closed loop system. After implementing the management model, effectiveness increased up to 78.95%. Reliability also increased from 47.4% up to 78.1%. It is concluded that these results are acceptable. It is recommended to continue with the improvement process and to monitor the indicators proposed in this investigation permanently.
