Assessment of the Reliability of Different Components of Fuel Measurement Systems Used in Angola

Abstract

The present work aims to assess the reliability of the different fuel measurement systems used at SNLD filling stations. As objectives, it is intended to propose a methodology for selecting the types and models of pumps to be used and when to replace them. The assessment of the risks in the replacement of a pump and the impact on the environment will also be examined. Although the discussion on pumps is not new in Angola, there are no published records on this subject, particularly in the selection of types and models of systems to be used and when to replace, using the different scientific tools. For the analysis of these equipments and their reliability, weibull distribution, ANOVA analysis and computational tools of probability and statistics with excel were used. The analysis by these two methods made it possible to certify the results obtained. A benchmarking was carried out at the filling stations of SNLD, Pumangol and Sonangalp to compare the quality of some services. The results achieved were discussed during the internship held at Petrotec. As a result, the components that have the most impact on the maintenance system of the different pumps, the causes of the faults and their respective costs were identified. The most vulnerable components identified are errors in the display, heating in the engine and malfunction of electrovalves.
