What's Happening?
The International Union of Marine Insurers (IUMI) has issued updated guidance warning of explosion risks associated with electric vehicle (EV) fires on roll-on/roll-off (ro/ro) ships. EV fires pose a significant challenge due to the high temperatures and toxic fumes emitted during thermal runaway. These fires can self-ignite or be triggered by nearby heat sources, making them difficult to extinguish. IUMI recommends using fixed firefighting systems early to prevent the fire from overwhelming the system. However, the gases emitted from EV fires, including hydrogen, can be explosive when mixed with air, posing additional risks during firefighting efforts.
Why It's Important?
The guidance from IUMI highlights the growing concern over the safety of transporting EVs on ro/ro ships. As the popularity of EVs increases, the maritime industry must adapt its safety protocols to address the unique challenges posed by EV fires. The potential for explosions adds a layer of complexity to firefighting strategies, necessitating careful consideration of ventilation and extinguishing procedures. This issue is critical for shipowners and operators to ensure the safety of their vessels and cargo, as well as the protection of crew members.
Beyond the Headlines
The design of modern PCTCs, with wide-open deck layouts, presents additional challenges for firefighting and stability. The risk of cargo shift due to wet decks can lead to serious consequences, emphasizing the need for tailored firefighting strategies. The maritime industry must balance effective fire suppression with maintaining vessel stability, particularly in adverse weather conditions.
