Abstract

Quantitative risk assessment (QRA) on protocol that allows maximum 96 40ft heavy LNG containers carried by a single ship in a dock was performed using applications EFFECTS and RISKCURVES, to investigate the hazard while loading and unloading ships exclusively carrying liquefied natural gas (LNG) tank containers in a dock. Through analyzing typical accident scenarios, the simulation predicted the range of the accident impact. Individual and social risk levels during loading and unloading were calculated to determine the hazard level while loading and unloading ships exclusively carrying LNG tank containers. The results show that the individual and social risk levels while loading and unloading ships exclusively carrying LNG tank containers are acceptable and meet the requirement of existing regulations.
