Abstract: By conducting research and analysis on fire prevention and control technologies for Ro-Ro new energy vehicle (NEV) ships at home and abroad in recent years, this study sorts out the major technological advancements in early fire detection and early warning, fixed fire suppression technologies, and emergency response technologies/equipment for Ro-Ro NEV ship fires. It summarizes the key challenges that still need to be addressed, including the single means of detection and early warning, delayed response, low efficiency in extinguishing deep-seated fire sources with high re-ignition risk, lack of multi-level comprehensive prevention and control strategies, and inefficient application of emergency response equipment. Corresponding solutions are proposed, such as enhancing early detection and early warning technologies, promoting the development of multi-agent combined fire suppression systems and new fire-extinguishing agents, and strengthening multi-level protective and response technologies/equipment. This study aims to provide technical guidance for fire prevention and control of Ro-Ro NEV ships and contribute to the safe development of the industry.
