LNG incidents

The LNG industry is currently facing challenges obtaining approvals for new receiving terminals. A factor of concern at public meetings relates to the potential hazards associated with marine transport accidents or terrorist events. Therefore, DNV Consulting was involved in a number of studies on LNG in 2004. These used Phast to look at the consequences of LNG marine incidents and compare various LNG decision making approaches.

Consequences of LNG Marine Incidents
The LNG industry is currently facing challenges obtaining approvals for new receiving terminals. A factor of concern at public meetings relates to the potential hazards associated with marine transport accidents or terrorist events. The purpose of this study is to develop a range of well conceived maximum credible failure cases from accidental or terrorism causes and to predict hazard zones using a well validated model. While additional experimental trials may be warranted, current results are of sufficient confidence to draw valid conclusions.

LNG Decision Making Approaches Compared
Hazard zones associated with LNG handling activities have been a major point of contention in recent terminal development applications. Debate has reflected primarily worst case scenarios and discussion of these. This paper presents results from a maximum credible event approach. A comparison of results from several models either run by the authors or reported in the literature is presented. While larger scale experimental trials will be necessary to reduce the uncertainty, in the interim a set of base cases are suggested covering both existing trials and credible and worst case events is proposed. This can assist users to assess the degree of conservatism present in quoted modelling approaches and model selections.
