Thermal exposure from burning leaks on LNG hoses: experimental results

This report summarises a series of tests on thermal impact to the surrounding from damaged Liquefied Natural Gas (LNG) hoses pressurized to approximately 10 bar. The results of temperatures of insulated surfaces, incident heat flux and flame dimensions are reported. For the design scenarios of 1" and 2" hoses (test 4 and 7) the distance to an incident radiant heat flux of 15 kW/m2 is 2 and 4 m, respectively. The equivalent distance to 5 kW/m2 is 3 and 9 m, respectively.
