Rapid phase transition of LNG.

Summary

Large quantities of LNG are being transported by sea from remote gas fields to distant markets. The transfer of LNG to and from an LNG carrier whilst loading or unloading, provides the potential for spillage of LNG onto water to occur. Under certain conditions, the vaporisation rate produced can be so high that physical explosions, termed rapid phase transitions (RPTs), can occur. These RPTs can generate air and underwater blast pressures which could damage adjacent plant or structures. BG and Gaz de France have been engaged in research into the factors influencing the occurrence and the possible consequences of RPTs. This research has been conducted on a collaborative basis with other organisations. It is now possible to provide a description of RPT phenomena and of the possible hazards presented by RPT events involving LNG or other cryogenic liquids.
