Product Engineering Assessment of Subsea Intervention Equipment Using SWARA-MOORA-3NAG Method

Abstract

Oilfields must increase their production due to the current price of oil barrels. The sale of these oilfields by big companies enabled new companies to enter the exploration and production segment of brownfields to increase oil and gas production through subsea intervention projects. However, these projects require specific product development that involves technical requirements that the engineering department must analyze. This research aims to apply the SWARA-MOORA-3NAG multicriteria decision analysis (MCDA) method in analyzing the technical proposals of subsea intervention equipment for ordering suppliers according to the engineering requirements defined at the initial stage of the projects of an oil and gas company. The research methodology was divided into five stages: (1) identification of the problem through observation of the current process and interviews with engineers; (2) data collection through bibliographic research in the Scopus database; (3) problem modeling; (4) proposition of the solution with the application of the SWARA-MOORA-3NAG method; and (5) analysis of the results found. The application of the SWARA-MOORA-3NAG method brought a new ordering of suppliers to the analyzed case, enabling comparison between the method previously used by the engineering department and the method proposed by this research, emphasizing that the MCDA methods can be inserted into the analysis processes of technical proposals in the engineering department of the company analyzed.
