The existing method of pipeline monitoring, which requires an entire pipeline to be inspected periodically, wastes time and is expensive. A risk-based model that reduces the amount of time spent on inspection has been developed. This model not only reduces the cost of maintaining petroleum pipelines, but also suggests an efficient design and operation philosophy, construction method, and logical insurance plans. The risk-based model uses analytic hierarchy process (AHP), a multiple attribute decision-making technique, to identify factors that influence failure on specific segments and analyze their effects by determining the probabilities of risk factors. The severity of failure is determined through consequence analysis, which establishes the effect of a failure in terms of cost caused by each risk factor and determines the cumulative effect of failure through probability analysis. The technique does not totally eliminate subjectivity but improves upon the existing inspection method. The entire methodology has been illustrated by case study application of a 1,500-km crude oil pipeline in the western part of India.
