Abstract

Offshore support base location selection is the determination of a strategic site for institution operations. The facility location decision involves institutions seeking to locate, relocate or expand their operations. The Offshore support base location decision process encompasses the identification, analysis, evaluation and selection among alternatives with respect to criteria selecting the best location among many alternatives is a Multi Criteria Decision Making (MCDM) problem. Analytic Hierarchy Process (AHP) was used for selecting the most suitable location for offshore support base in Ghana for subsea engineering companies for the TEN project in Ghana. The related problem includes four possible alternatives and four criteria to evaluate them. The four locations considered are Takoradi port, Atuabo free port, Lagos Deepwater and Offshore Logistics (LADOL), Tema Shipyard, and the main criteria for evaluation are Quayside facility, Water depth, Plot size, and Cost of operation. The result indicated that the Atuabo Freeport Port has the highest net outranking flow of 0.402643 in comparison with the rest of the locations and hence the best offshore based location.
