Container Ship Fires Occur Every 17 Days: Lithium Batteries and Hazardous Cargo Remain the Biggest Threat
The global shipping industry is facing an increasing safety challenge as fires aboard container ships become more frequent. According to the latest Allianz Commercial Safety & Shipping Review 2026, a major container ship fire now occurs approximately every 17 days, highlighting the growing risks associated with hazardous cargo and lithium-ion batteries.
Although the total number of maritime losses has declined over the past decade, fires remain one of the fastest-growing causes of serious shipping incidents. Experts warn that the rapid increase in the transportation of lithium batteries, electric vehicles, and other dangerous goods is significantly raising the risk of onboard fires.
Lithium Batteries Under the Spotlight
Lithium-ion batteries have become an essential part of modern trade, powering everything from smartphones and laptops to electric vehicles and industrial equipment. However, they also present unique challenges during transportation.
If damaged, improperly packed, or exposed to excessive heat, lithium batteries can enter thermal runaway—a chain reaction that generates intense heat, toxic gases, and fires that are extremely difficult to extinguish.
Unlike conventional fires, lithium battery fires can reignite even after appearing to be under control, making them one of the most dangerous emergencies at sea.
Misdeclared Dangerous Goods Continue to Be a Major Risk
According to maritime safety experts, one of the biggest problems is the incorrect declaration of hazardous cargo.
When dangerous goods are mislabeled or declared as ordinary cargo, crew members may be unaware of the risks, and containers can be stowed in unsuitable locations. This significantly increases the likelihood of a fire spreading before it can be effectively controlled.
Industry organizations estimate that cargo misdeclaration remains a contributing factor in a substantial number of serious container ship fires worldwide.
More Than 200 Ship Fires Recorded in 2025
The Allianz report recorded more than 200 ship fires worldwide during 2025, making it one of the highest annual totals in recent years.
While not all of these incidents occurred on container vessels, container ships continue to represent one of the sectors facing the greatest fire-related risks due to the enormous variety of cargo carried on board.
As global demand for battery-powered products continues to grow, experts expect the volume of lithium battery shipments to increase significantly over the coming years, further increasing the importance of cargo safety.
Shipping Industry Responds
To reduce the growing threat, shipping companies, classification societies, and international organizations are introducing new safety measures, including:
- Enhanced cargo declaration verification.
- AI-powered cargo screening systems.
- Improved fire detection technologies.
- Updated firefighting procedures for lithium battery incidents.
- Stricter regulations for transporting dangerous goods.
Industry leaders emphasize that preventing cargo misdeclaration is one of the most effective ways to reduce the number of serious fires at sea.
Safety Starts Before the Voyage
Every container loaded onto a ship represents a responsibility shared by shippers, freight forwarders, ports, and carriers. Accurate cargo documentation, proper packaging, and compliance with international dangerous goods regulations remain essential for protecting crews, vessels, cargo, and the marine environment.
Conclusion
Container ship fires are becoming one of the most significant safety challenges facing modern shipping. With a major fire occurring approximately every 17 days, the maritime industry must continue investing in advanced detection systems, stricter cargo controls, and improved crew training.
As the transportation of lithium-ion batteries and hazardous cargo continues to grow, ensuring safe shipping practices will remain a top priority for the global maritime community.
