Estimation of Failure Probability Using Fault Tree Analysis and Fuzzy Logic for CO2 Transmission

Ahmed Ali Baig and Risza Ruzli
Abstract—In this paper a methodology is presented to estimate the probability of failure of CO2 transporting pipeline. The causes of failure are analyzed using Fault Tree Analysis (FTA) and the scope of study is emphasized on the puncture or holiday formations in pipelines due to corrosion eventually leading to leakage of CO2 . For new systems the ambiguity in data or unavailability of failure data is one of the key problems encountered. Therefore a methodology is presented in this paper that uses expert’s elicitation and converts it into crisp failure data using Fuzzy Logic approach. The combination of FTA with fuzzy logic will help in artificially generating the unavailable data. The puncture scenario of some existing CO2 pipelines is also presented in this paper.

Index Terms—Corrosion, CO2 pipeline, corrosion simulation, fuzzy set theory, fault tree analysis.
