Piping Material Selection for Firewater Systems on Offshore Platform using the Multi Criteria Decision Making Method

Abstract

The aim of this research is to evaluate the piping material selection using Multi-Criteria Decision- Making (MCDM) methods for a firewater system in offshore oil and gas industries. This study uses Cambridge Engineering Selector (CES) software, Analytical Hierarchy process (AHP) and The Technique for Order of Preference by Similarity to Ideal Solutions (TOPSIS) technique from MCDM to determine the weight factor and material ranking respectively. Results of the study would conclude that Glass Reinforced Epoxy (GRE) material ranked the most optimal pipe material selected for a firewater system.
