A study developing the dry powder fire extinguishing system inside the simulated machinery spaces of small ship was performed. Fire tests were conducted inside the compartments having volume $8m^3,\;4.5m^3\;and\;2.9m^3$ respectively. The openings and fans were established on the walls of the compartments. Diesel oil was used for the test fuel. In addition fire extinguishing nozzles using dry powder were installed downward at ceiling and horizontally at the wall or conner. All fires in the test were extinguished under system activation and there was no reignition.

Developed and conducted a performance test of the Water mist system that is satisfied with the requirement of a fire test requiring Class 3 Engine Mock-up exceeding net volume $3,000m^3$ as per IMO's MSC/Circ. 668 Appendix B(Test method for fire testing equivalent water-based fire-extinguishing systems for machinery spaces of category A and cargo pump rooms).Even though fuel atomizing was continued for 15 sec. after stopping of the system according to the test method relating to the atomizing fire type, no fire was reignited. This result shows the excellence of the system. There was no damage to the contents of the system after the test.
