Abstract: A series of 16 tests have been conducted at the Naval Weapons Center involving the spill and ignition of liquefied natural gas (LNG) on water. Two kinds of fires have been studied namely, pool tires and vapor cloud fires. The principal objective of the tests was to measure the thermal radiation output of LNG fires on water, and to study their main physical characteristics. The quantities of spilled LNG varied between 3 and 5.5 m3 with spill durations from 30 to 250 s. Thermal radiation from the fires was measured using wide-angle and narrow-angle radiometers and a spectrometer. Based on the corroborating radiation data from independent measuring instruments, a mean value of 210 kW/m2 has been obtained for the flame emissive power in the pool fire on water experiments. From the spectral record the fiame temperature is estimated to be 1500 K. While Ihis radiating temperature is higher than previously expected, much of this radiation is from water and carbon dioxide.
