(91d) Safety Assessment of Lined Rock Cavern LNG Storage Tank

The natural gas consumption is expected to grow significantly in the next decades. The need for building LNG import terminals with significant storage capacity is quite often a critical aspect due to restriction of land in the area of interest and environmental constraints. A new concept for the storage of LNG in underground mined rock caverns is considered as very efficient in term of land occupation, environmental and visual impact at ground surface, safety and cost.

This paper presents risks associated in project developing of a Lined Rock Cavern System and discusses their risks mitigation.
