碩士 / 國立臺灣海洋大學 / 運輸科學系 / 99 / Over the past decade, liquefied natural gas in Taiwan has increased in popularity, as a result the number of transport ships carrying liquefied natural gas has increased. However, this gas is kept at ultra-low temperature of -162 ℃ and when exposed to room temperature can cause the liquid to leak into the atmosphere creating a dangerous vapor cloud. If the vapor cloud encounters fire, then this will cause a huge explosion, making the LNG container ships potentially dangerous. Understanding the cause of this type of accident is particularly important .This study using the major hazard evaluation of the accidental explosion when the ship’s liquefied natural gas leaked determines the impact of the explosion in regards to the extent of the spread of the fire. First using the vapor cloud TNT-equivalency methods, the result equals to the equivalent of solving the explosion of tons of TNT explosive; then getting the radius of the death range 、the serious injuries, the minor injuries and property damage .
This research can be used in the future for liquefied natural gas ships, to understand the impact of explosions caused by accidental leaks to help with the assessment of the evacuation of personnel, in order to reduce personnel casualties.
