Abstract : A series of tests was conducted to evaluate the capability of water mist nozzles for extinguishing fires in engine and generator rooms on U.S. Army watercraft. Three types of nozzles were evaluated: single fluid low pressure, single fluid high pressure and dual fluid (air/water) nozzles. The international Maritime Organization's (IMO) test protocol for halon alternatives in machinery spaces and pump-rooms was used. The tests were conducted in a simulated machinery space 9.1 x 9.1 x 4.6 m. The best performance was obtained with a single fluid high pressure nozzle which was able to extinguish all of the fires in the IMO test protocol except the bilge-fire mist nozzles in the bilge areas.
