An Investigation of Corrosion Risks in the Oil and Gas Pipelines Using Analytical Hierarchy Process and Fuzzy Analytical Hierarchy Process

The products of crude oil and gas can be considered as the main backbone of the global economy. The oil and gas industry has faced many potential risks and problems when the oil and gas is pumped into the pipelines during the production, transportation, and processing. Although experts are solving these problems; some have been difficult to resolve and remained as a complex issue. Among these problems, were the issues of corrosion in the oil and gas pipelines. Risk assessment of the oil and the gas pipelines is considered as the core content of the integrated management of the entire pipelines. This paper aims to assess the risks of corrosion in the oil and gas pipelines in Sabratha platform and Wafaa field. First, the Analytical Hierarchy Process (AHP) is used to identify the risk rate of the different types of corrosion. Second, the technique of Fuzzy Analytic Hierarchy Process (F-AHP) is also used to identify the risk rate of the different types of corrosion. The comparison between the classical (AHP) and the (F -AHP) indicate that the results of both techniques were close.
