Blast Waves Produced by Rapid Phase Transition of LNG on Water

Massive offshore and onshore storage of LNG have addressed the public concerns on all possible hazards on people and other installations either onshore or on ship. A discussion on blast waves produced by rapid phase transition of LNG on water covers risks related to the release of large amount of LNG; possible accidental scenarios; the phenomenon of Rapid Phase Transition (RPT); use of an acoustic model to define explosion pressure and total energy produced by the RPT of LNG; significant impacts to public safety and property from accidental spills; and acoustic evaluation of pressure wave produced by the rapid phase transition of LNG released accidentally on water. This is an abstract of a paper presented at the 42nd Loss Prevention Symposium (New Orleans, 2008).
