Análisis de mantenimiento aplicando ingeniería de la fiabilidad en los tanques de almacenamiento de combustible diésel utilizados para la generación de energía en la Empresa Petroriental S.A.

Abstract

To carry out a maintenance analysis applying reliability engineering in the thanks for storing diesel which is used to generate energy for the blocks 14 and 17 at Petroriental S. A. For this, it was necessary to collect the technical information of 23 tanks. With the information, an analysis of the functions of tank elements was carried out in order to establish their anti-funtions (fail- ures), which led to detect the cause for such failures; this is known as failure mode. After ob- taining the previous analysis, it was necessary to make the calculations to determine the time in which each failure of the thank elements occurs which is also known as average time between failures. Due to the time calculated the inspections planned to the tank elements were carried out before a failure could occur again, these inspections were based on the items mentioned in the API 653 norm for reconstruction, alteration, and modification of tanks. For the structural system, an average time of 144 hours was obtained between failures of the rings element with the highest value and the accessories system in which the sink element reflects a higher time between failures with 24 hours. With the research carried out, it is concluded that the average time between failures increases since it is taken into account that the failure could be avoided, therefore inspections and preventive maintenance tasks are carried out. It is recommended that Petroriental company implements this maintenance plan base on the reliability in both, block 14 and 17.
