THE EFFECTIVENESS OF "FIRE GAS RECIRCULATION" EXTINGUISHING SYSTEMS ON SHIPBOARD MACHINERY SPACE FIRES. PHASE II

This report details a series of tests conducted at the U.S. Coast Guard's Fire and Safety Test Facility in Mobile, Alabama, to further evaluate the extinguishing capabilities of the machinery space fire gas recirculation network installed onboard the M/V RHODE ISLAND. This additional test program was designed to examine the empirical relationships of certain factors relevant to the combustion environment. As in the previous test series, full scale fires were started in the machinery space of the M/V RHODE ISLAND, which were then successfully extinguished by actuation of the installed fire gas recirculation networks. In addition to parameters evaluated in the first test series, the following three factors are also noted: (1) preburn length vs. control time; (2) free vent area vs. control time; and (3) recirculation volume vs. control time. To perform these tests, additional ventilators, power blowers, and crosslink ducting were installed in the top of the machinery space casing, and additional gas sampling equipment and instrumentation provided.
