After there was a minor fire on the American aircraft carrier Ford, it was discovered that there was an average of 53 fires annually on American Navy vessels. Most of this occurs during maintenance operations while a ship is in port or a drydock but there are outbreaks, generally minor, of fire on deployed ships. The most common location for fires is in the laundry space. Dealing with laundry fires is the most practiced fire drill at sea because it’s the most common fire event.
From lithium-ion battery cargoes to engine room accidents, fire hazards at sea are more complex than ever before. Shipowners, operators, and insurers are compelled to reconsider the usual solutions. Consider the most common reasons for such fires. Several fires on large car carriers, container ships, and tankers have underlined weaknesses in both cargo handling and onboard systems. Many of these fires originate from a small number of repeatable points of failure. These include mislabelled or incorrectly stowed hazardous goods, electrical malfunctions, fuel system leaks, and contractor or crew error during maintenance or welding. The rise of electric vehicles and lithium-ion battery cargoes has made it difficult to create ways to extinguish such fires that standard fire suppression systems are often unable to handle.
The most frequent events causing onboard fires are hazardous materials not properly described, particularly lithium batteries, flammable liquids, or oxidizers. Then there are engine room fires caused by leaking fuel, lube oil, or hydraulic fluid contacting hot surfaces, plus lack of insulation or maintenance. Electrical failures include overloaded circuits, short circuits, corroded wires, or unsealed connections in humid conditions. Other frequent cause are crew quarters fires and hidden smoldering events in reefer areas or control rooms. These are difficult to detect before ignition while inspection cycles often overlook deteriorating wire conditions
Shipboard work accidents include welding, grinding, or cutting without fire watch, permits, or isolation of flammable materials. Human error leads to expansive claims and delays where training and permit-to-work enforcement are crucial. Then there is poor cargo arrangement with inappropriate dangerous goods placed too closely, as when oxidizers are near items that ignite readily. Improper stowage contributes to rapid spread of fires aboard container ships and RoRo/Roll On-Roll Off vessels.
Galley and crew quarters fires are caused by unattended cooking, grease build-up, or malfunctioning galley appliances. This is especially common on cruise ships and mixed-use vessels with passenger living spaces. These are typically localized but still dangerous; many disable ventilation or spread via ductwork.
While no vessel can eliminate risk entirely, the most effective systems start with improved cargo scrutiny and more intelligent stowage decisions. With real-time monitoring, modern tools and practices are giving shipowners more control than ever before. The strategies below reflect proven methods drawn from incident reports, safety audits, and regulatory best practices.
Fire emergency response exercises include sustained fire containment exercises for the cargo spaces, engine room, and crew or passenger quarters. There should be monthly documented onboard drills. Then there are fire suppression systems; carbon-dioxide fire suppression, water mist systems and foam/water-spray equipment. All this has had an impact on insurance premiums which have gone up fifteen to thirty percent for ships carrying cargoes containing a lot of lithium-ion batteries in electric or hybrid vehicles.
