Fire safety of ships is a key issue as evacuation and extinguishment is more difficult at sea than it would be on land. There is therefore a long tradition and regulations in place to maintain the fire safety of ships. The current shift to more sustainable transport solutions has now led to the introduction of lithium-ion batteries for ship propulsion. These can offer significant benefits in terms of reducing greenhouse gas and particulate matter emissions. They also introduce new risks, however. When damaged, li-ion batteries may go into thermal runaway, a state that produces significant amounts of heat combined with flammable and toxic gas. This is a challenge, and safety is one of the key questions asked when introducing battery propulsion at sea. Extinguishment of battery fires is a piece of the puzzle when it comes to enabling safe battery propulsion at sea. Fire suppression systems are used today for such applications, yet no standard test method exists to evaluate their performance. This work proposes an approach that may be used to evaluate such systems and that can be used as input towards the development of a test method. Specifically, a test method aimed at evaluating the performance of fire suppression system under critical battery failures and at lowering the risk for module-to-module propagation. The test method designed here performed well and sustained the 18 tests that were done. Overall, repeatable test conditions were obtained that allowed for the performance of fire suppression systems to be investigated. All fire extinguishing systems had a positive impact in some position but not all points and it was not possible to draw any conclusion on their ability to mitigate the risk for module-to-module propagation. The tests showed that mitigating this can be possible with careful design of systems and perhaps combinations of different means. |
