E001 Earthquake Analysis and Design Issue of an Offshore Gravity Based LNG Terminal in High Seismic Environment F.F. Tajirian* (Chevron Energy and Technology Company) SUMMARY This paper addresses several earthquake design and analysis challenges encountered during the preliminary design phase of a large offshore gravity based (GBS) LNG storage and regasification facility. The structure was to be located in a zone of high earthquake activity. The concrete structure was rectangular in plan and measured 160 m by 103 m in approximately 25 m of water. The procedures used to perform soil-structure interaction (SSI)analysis were summarized. A new procedure using distributed
