To improve the reliability of offshore launch propellant filling systems and mitigate potential hazards in the case of data and knowledge scarcity, a weighted Failure Mode and Effect Analysis (weighted-FMEA) methodology is proposed. A detailed hazard identification framework is proposed to identify potential failure modes of the systems. The Best Worst Method and a comparative matrix is then combined to unify the differences between systems and components. Subsequently, the grey theory is used to mitigate the subjectivity/uncertainty of experts’ judgment. Critical failures and corresponding preventive actions are recommended based on the analysis results. The superiority of the proposed model is confirmed by a comparison analysis with existing methods. Overall, the proposed weighted-FMEA model helps to prevent accidents and ensures the safe operation of offshore propellant-filling systems.
