With incidents like the Morning Midas<\/em> fire<\/a> continuing to underscore the risks of EV-related car fires aboard ship, operators are urgently seeking more effective solutions. A new brine-based firefighting system, developed by Skansi Offshore in close cooperation with Knud E. Hansen, is claimed to offers a simple, robust and environmentally responsible answer.<\/p>\n The system is operational aboard Faroese ship operator Smyril Line\u2019s RoPax ferry Norr\u00f8na<\/em>,<\/a> and is scheduled for installation on two new RO\/RO vessels currently under construction.<\/p>\n Unlike traditional fire suppression methods \u2013 which act from the outside and often fail to extinguish the core fire \u2013 the brine-based firefighting system targets the battery directly from inside the vehicle. In the event of a fire, one window is penetrated, and cold, saturated brine is delivered directly into the vehicle. This allows the fluid to pool around the battery compartment, rapidly cooling the cells, limiting oxygen exposure, suppressing flammable materials, and even short-circuiting and depowering the battery.<\/p>\n \u201cWe believe this system sets a new standard,\u201d says Finn Wollesen, managing director, Knud E. Hansen USA Inc. \u201cIt\u2019s low-tech in the best way \u2013 reliable, proven, and easily maintainable. Most importantly, it addresses the real issue: Heat\u2013 not just the flames, but the fire inside the battery.\u201d<\/p>\n In a full-scale fire test conducted in the Faroe Islands, the brine-based firefighting system is reported to have extinguished a fully developed EV fire in under one hour, including response times etc. In contrast, lithium-ion battery fires often burn for 24 hours or more when left to self-extinguish, and can reignite multiple times.<\/p>\n \u201cMost systems act externally,\u201d says Frederik Jonassen, lead engineer, brine systems. \u201cOurs delivers cold brine inside the car, as close to the battery pack as possible. It cools, displaces flammable gases, and helps short-circuit and depower the battery. The high salinity also absorbs heat efficiently and limits fire spread. It\u2019s an elegant way to break the thermal runaway process before it escalates.\u201d<\/p>\n The post New brine-based firefighting system developed to counter EV car fires<\/a> appeared first on Marine Log<\/a>.<\/p>\n<\/div>\nProven performance<\/h4>\n
