- Abstract
- An investigation of the hazard of spillage of liquefied natural gas (LNG) onto water is descried. About 2000 gallons of LNG were consumed in various tests. The initial vaporization rate of LNG following spillage was found to be 0.037 lbs/ft2 sec; when the spill was confined, this vaporization rate was moderated after about 20 seconds by the growth of an ice layer on the water surface; when the spill was unconfined, a coherent ice flow was not observed and the vaporization rate was essentially time-independent. The maximum diameter (in feet) of the spreading LNG pool was found to be given by 6.3 W1/3 where W is the weight of LNG in pounds.
