Abstract

The maintenance and conservation of oil equipment in Ecuador is of great importance for its optimal operation. Technological advancements and the increasing complexity of technical systems have led to the search for alternative maintenance strategies that allow predicting the behavior of machines. For this reason, the present study aims to determine the Reliability Indices of the Two-Phase Separator (Crude Desalter) V-320 of Block 12 Petro Ecuador based on the Weibull Distribution. The methodology used was an analysis of equipment downtime due to failure based on its logbook. From 2010 to 2023, there were 21 corrective maintenance data points, from which the time of proper operation was extracted for analysis. All data points were used for this study, and they were linearized on the Weibull logarithmic sheet to determine two parameters: α (characteristic life parameter) and β (scale or shape parameter), which are parameters of the Weibull distribution. The calculation of the α and β parameters resulted in 5588 h and 1.29, respectively, allowing us to predict the probability of proper operation (reliability) or malfunction (unreliability) over a specific period, which can vary according to the equipment maintenance planning needs. It is concluded that the Weibull analysis is a predictive maintenance tool applied to estimate the probability based on measured data.
