LNG INCIDENT IDENTIFICATION: A COMPILATION AND ANALYSIS BY THE INTERNATIONAL LNG IMPORTER’S GROUP

摘要

Safety in LNG Operations has been of utmost importance to the industry since its inception. The International LNG Importer’s Group (GIIGNL) first began a comprehensive study of incidents relating to the global LNG industry in 1992 and has recently updated its work during 2001 to include all incidents reported up to that time. The work has been undertaken by a Study Group comprising representatives from GIIGNL Member companies in the USA, Europe and Japan who obtained data from all the GIIGNL Members. The goals of the study were as follows: rn1. To identify actual incidents of LNG or vapor release for possible inclusion in the hazard analysis of new, modified, or existing facilities. rn2. To advise on the severity of the identified LNG incidents to assist in evaluation of their importance and potential consequences. rn3. To provide information on the circumstances under which the identified LNG incidents occur (and their frequency where possible) to assist in the evaluation of their relevance to the particular LNG facility under review. rnIncidents have been categorized by type, function being performed, and severity. A frequency and trend analysis has been performed on the data presented in order to identify trends and draw conclusions. rnThe general trend is for a decrease in the relative number of events where significant amounts of hydrocarbons are released. This indicates continual improvement in mitigation measures and procedures at facilities.
