Vessel Fires Increase in Numbers and Severity

Why It Matters

The accelerating fire risk threatens maritime safety, drives up insurance liabilities and could disrupt global supply chains, prompting tighter cargo declaration and regulatory action.

Key Takeaways

• Lithium‑ion batteries driving up ship fire incidents
• Misdeclared scrap metal often hides batteries, causing fires
• UK brigades see 4.8 battery fires daily, up 147%
• Two container fires surpassed $10 million insurance retention

Pulse Analysis

The surge in lithium‑ion battery fires reflects the broader electrification of global trade. As electric vehicles, consumer electronics and energy storage systems flood ports, shippers increasingly load batteries—often concealed within scrap metal or misdeclared cargoes—onto vessels not designed for such hazards. Existing classification systems, like the IMDG Code, allow certain battery‑laden goods to be labeled non‑dangerous, creating gaps that insurers and regulators are now scrambling to close.

For insurers, the financial stakes are climbing rapidly. Gard’s report of two container fires breaching a $10 million retention underscores the potential for catastrophic losses. Premiums for marine hull and cargo policies are expected to rise, and insurers are demanding stricter compliance documentation and real‑time monitoring technologies. Ship operators, in turn, face higher operational costs as they invest in fire‑suppression equipment, crew training, and cargo verification processes to mitigate the risk of thermal runaway incidents.

Looking ahead, the industry is likely to adopt more robust verification mechanisms, including mandatory battery‑energy disclosures, enhanced scanning of bulk cargoes, and tighter enforcement of the IMSBC Code for scrap metal shipments. Collaborative efforts between classification societies, insurers, and port authorities could standardize best practices, while emerging sensor technologies promise early detection of temperature anomalies. These steps aim to curb the fire trend, protect maritime assets, and preserve the reliability of global supply chains.
