Résumé
In the marine industry, machinery failure has been cited as the foremost cause of shipping incidents. No matter how well designed, marine machinery systems will not remain safe and reliable if not properly maintained. The challenge in the industry is how to maintain such complex systems. One of the major problems is the selection of an appropriate maintenance strategy for the various components of the system. In deciding on the appropriate maintenance strategy, a thorough risk analysis must be carried out to identify the most critical components of the various systems. Different techniques such as failure mode effect analysis (FMEA) have been used in the industry to prioritize risk of failure modes. The classical failure mode and effect analysis employed by the industry has been criticized as having some flaws, which include subjective risk prioritization and lack of comprehensive evaluation. This study presents an enhanced FMEA methodology for risk assessment in marine machinery systems. By integrating two Multi-Criteria Decision-Making (MCDM) tools—Fuzzy Analytic Hierarchy Process (FAHP) and Fuzzy Technique for Order of Preference by Similarity to Ideal Solution (FTOPSIS)—the proposed methodology addresses the limitations of the traditional FMEA. The FAHP method refines the weight allocation process for risk factors using expert judgment while accounting for uncertainty, and FTOPSIS ranks failure modes based on their proximity to ideal solutions. The involvement of multiple subject matter experts (SMEs) ensures diverse perspectives, improving the robustness of the analysis. The practical findings of this paper demonstrates that traditional RPN can mis-prioritize failure modes. The FAHP-FTOPSIS approach provides more targeted, expert-driven insights, and reinforces the need for advanced methodologies in critical, high-stakes marine engineering applications where failure prevention is crucial.
