Frequencies of leaks increase with aging pipelines and environment factors. Consequences of leaks can be severe because population densities near pipeline routes have increased and also because of environmental concerns. Thus, the uncertainty concerning when and where leaks would occur becomes a major consideration in identifying the leak-prone segments. This paper presents a statistical method based on the Bayes? theorem, to assess the probability of leaks for different portions of a pipeline system as a function of significant characteristics. The illustrated case study, in which this method was applied successfully, describes a Bayesian diagnostic model and its application to a cast iron gas pipeline system.
