Safety Assessment of LNG Terminal Focused on the Consequence Analysis of LNG Spills

Abstract The consumption of natural gas worldwide will almost double by 2030 and the rate of increase is 2.3% per year. Demand is projected to grow most rapidly in Africa, Latin America and developing Asia. Meanwhile, the percentage of the global demand on primary energy will increase from 21% in 2002 to 25% 2030. Gas-resources will increase in global demand and proven reserves are now equal to about 66 years of production at current rates. Cumulative investment needs for gas-supply infrastructures to 2030 will amount to $2.7trillion, or about $100 billion per year. Therefore, LNG is and has been an important, reliable part of the world energy infrastructure for almost 40 years. To understand safety issues and hazard characteristics in LNG terminals, we find out possible accidents scenarios come from historical data and incident-tree analysis for LNG release. Then, the resultant accident scenarios have been modelled with varying tank-capacities and hole-sizes; the consequence analysis has been performed to discuss relevant safety issues.
