Onboard Fire Incidents on Naval and Commercial Vessels at Sea

Summary

A minor fire aboard the American aircraft carrier USS Ford prompted a review revealing that U.S. Navy vessels experience an average of 53 fires per year, with most occurring during maintenance operations in port or drydock and the most common location being laundry spaces. Beyond military vessels, commercial ships including large car carriers, container ships, and tankers face increasingly complex fire hazards driven by factors such as mislabeled hazardous cargo, electrical malfunctions, fuel system leaks, and crew or contractor errors during maintenance. The growing prevalence of electric vehicles and lithium-ion battery shipments has introduced a particularly dangerous new challenge, as standard fire suppression systems are frequently inadequate to combat such fires. Common causes also include engine room fires from leaking fluids contacting hot surfaces, overloaded or corroded electrical systems, smoldering fires in refrigerated cargo areas or control rooms, and unsafe hot work practices like welding without proper fire watches or permits. These recurring vulnerabilities are compelling shipowners, operators, and insurers to fundamentally reconsider conventional fire prevention and suppression approaches across the maritime industry.
