Growing Safety Concerns Over EV Battery Fires at Sea
As the global shipping industry adapts to the rapid rise of electric vehicles (EVs) in cargo, the American Bureau of Shipping (ABS) has taken a crucial step forward by advancing its fire modelling capabilities to better assess and manage the unique risks posed by lithium-ion batteries transported by sea. The new developments are part of ABS's broader strategy to enhance safety standards as the maritime sector faces unprecedented challenges from the increasing transportation of battery-powered vehicles.

The move reflects growing concern over the fire hazards linked to EV batteries, which, if not properly managed, could have catastrophic consequences aboard ships and in port facilities.

The Rise of EV Shipping Brings New Safety Imperatives
The surge in global demand for electric vehicles has led to a parallel increase in the volume of EVs shipped across continents. Car carriers, roll-on/roll-off (Ro-Ro) vessels, and container ships are now frequently transporting thousands of EVs per voyage.

While this represents an important evolution in the auto industry and global logistics, it also introduces new safety risks that traditional fire safety systems on vessels were not designed to handle. Lithium-ion batteries, which power most EVs, pose a significant fire and explosion hazard if damaged or improperly stored.

The unique nature of battery fires—including the risk of thermal runaway, intense heat, toxic gas release, and re-ignition—requires a fundamental rethinking of maritime fire safety.

ABS Leads Industry Response with Scientific Fire Modelling
ABS, one of the world's leading classification societies, is taking the lead in addressing these challenges through advanced scientific fire modelling. By using computational simulations, ABS is now able to better understand the behavior of fires involving lithium-ion batteries in enclosed spaces such as car decks or cargo holds.

These models allow safety engineers to predict:

• How quickly a fire could spread
• The amount of heat and toxic gases generated
• The effectiveness of different suppression systems and ventilation designs
• The structural impact on ships in the event of a battery fire

This data-driven approach enables the design of more robust safety measures, tailored to the specific risks of transporting electric vehicles and battery-powered cargo.

Collaborative Efforts with Industry and Academia
ABS’s work on fire modelling is part of a collaborative initiative that brings together shipping companies, port authorities, battery manufacturers, and academic researchers. By combining real-world case studies with laboratory testing and advanced computer simulations, the goal is to establish industry-wide best practices for managing the fire risks associated with EV transport.

This approach reflects the growing consensus that no single entity can tackle the safety challenges of battery-powered cargo alone. Cross-sector collaboration is essential to develop effective solutions that are both technically sound and economically feasible.

Regulatory Momentum Building for EV Cargo Safety
The maritime industry is also witnessing a regulatory shift as classification societies, insurers, and governments recognize the need for updated safety standards. International Maritime Organization (IMO) guidelines are being revisited, and new recommendations specific to the carriage of EVs are under discussion.

ABS’s fire modelling work is expected to play a key role in informing these evolving regulatory frameworks by providing evidence-based insights into how fire risks can be mitigated without hindering the growth of green transport and trade.

Ports and Logistics Hubs Face Similar Challenges
The risk of EV battery fires extends beyond ships to port terminals and logistics hubs where thousands of electric vehicles are stored and handled. As part of its broader fire risk research, ABS is also advising port authorities on how to improve fire detection, containment, and emergency response protocols related to EV cargo.

These measures are especially crucial in large-scale automotive export-import terminals, where the density of vehicles and proximity to fuel and infrastructure could amplify the impact of an uncontrolled fire.

Driving Innovation in Fire Detection and Suppression Systems
The advancement of fire modelling by ABS is also stimulating innovation in fire suppression technology. Traditional CO₂-based systems or water deluge systems used on vessels may not be fully effective against lithium-ion battery fires.

New solutions under exploration include:

• Aerosol-based suppression agents
• Water mist technologies
• Smart sensors for early thermal detection
• Specialized fireproof containment zones within ships

ABS’s modelling helps evaluate these systems under simulated real-world conditions, accelerating the development and adoption of new safety technologies.

A Critical Step Toward Sustainable and Safe Maritime Transport
As the global shipping industry commits to decarbonization and embraces the transport of electric and hybrid vehicles, ensuring the safety of such cargo has become a non-negotiable priority. The advanced fire modelling capabilities developed by ABS represent a critical step in bridging the gap between innovation and safety.

By providing science-based risk assessment tools, ABS is helping shipowners, designers, and regulators make informed decisions that protect lives, cargo, and the environment without compromising on sustainability goals.

Preparing for the Electric Future of Shipping
The rapid rise of electric vehicle transportation by sea is reshaping the maritime landscape, introducing both opportunities and new challenges. ABS's leadership in advancing fire modelling underscores the industry's proactive approach to managing EV battery risks, ensuring that as shipping moves toward a greener future, safety remains firmly at the forefront.

With continued collaboration, technological innovation, and regulatory evolution, the maritime sector is laying the groundwork for a safer, cleaner era of global trade.
