Study on Fire Risk of Pure Car Carrier Vessels Carrying New Energy Vehicle

Along with the prosperity of the global new energy vehicle transportation market, the safety problems during the shipping of new energy vehicles begun to appear. Once a fire accident occurs in a new energy vehicle transported by ship, this accident is very difficult to dispose of and the resulting loss will be great. Based on the transport characteristics of those ships, the risk factors that may cause fire accidents in the shipping process are identified, the fire risk evaluation model of the car carrier is established, and the entropy weight TOPSIS method is applied in ranking the risk level of the factors in the model for fire risk assessment. The result shows that in Level 2 indicators, Operator mistake is the most likely cause of ship fire accidents, which means ship personnel management should be strengthened. Besides, in Level 3 indicators, the failure of lithium batteries in new energy vehicles is the most essential factor for car carriers to focus on in their fire accident prevention efforts. The results of this paper can help improve the maritime safety management of car carriers and can also provide some guidance for the risk prevention of fire accidents during the transportation of other ship categories.
