Demonstrative Safety Assessment of Lng Storage Facility Earthquake Resistance, and Reinforcement of Crisis Management At Lng Receiving Terminals gestion Des Risques Sur Le Site Du Terminal Methanier Et Evaluation De La Resistance Au Seisme Des Reserv

摘要

On January 17, 1995, a powerful earthquake with a seismic intensity of Magnitude 7.2 (Southern Hyogo Earthquake) shook the southern region of Hyogo Prefecture, located in west-central Japan. The quake inflicted serious damage on the residents and properties of the region, resulting in many number of deaths and destroyed structures. Although Kansai Electric Power Co., Inc. and Osaka Gas Co., Ltd., suppliers of electricity and gas in this region, also suffered damages to their distribution facilities and gas piping in the urbanized areas of the region, the LNG receiving terminals did not suffer much damages and could continue their operation. Nevertheless, based on the lessons learned from the disaster, the two companies have improved their crisis management measures in preparation for such disasters. Also, Kansai Electric Power conducted evalautions of the earthquake resistance of the LNG tanks and the results of an experiment to verify the earthquake resistance of a 1/8 scale model tank. The results of this experiment are reported here.
