Research of an Economic Evaluation Method of Offshore Oil and Gas Multi-Platform Power System with Life Cycle Cost

Abstract

This paper analyzes the relevant research data of the economic evaluation method of the offshore multi-platform interconnected power system, studies the economic evaluation method of the offshore platform power system, and puts forward the application of the full life cycle cost method to the economic evaluation of the offshore multi-platform power system. The method of quantifying the index is explored, and the variables in the function relation are determined by Delphi method, then the original analytic hierarchy process is improved to calculate the weight. The research results of this paper have been verified by the actual data of multi-platform interconnected power system in Jinzhou 25-1 offshore oil field. The results show that the proposed economic evaluation method of offshore oil and gas field platform power system based on full life cycle cost is effective.
