Risk analysis for fire and explosion accidents on chemical tanker under fuzzy-AHP approach

To enhance the safety of maritime transportation, a risk analysis method is conducted for fire and explosion accidents involving dangerous goods at sea. It begins by categorizing dangerous goods based on their distinct characteristics and then identifies five key risk factors: human, ship, cargo, environment, and management. Then, risk evaluation is made based on fuzzy-AHP, the evaluation index system of primary and secondary risk factors is established, and the weight and risk evaluation value of each risk factor are calculated by integrating expert scores. Finally, the qualitative and quantitative risk analysis is summarized, and the corresponding countermeasures and suggestions are put forward from five aspects according to the existing safety management problems.
