Abstract
A storage system is provided that includes a primary container, a first insulation layer, a secondary container, a secondary bottom, and a second insulation layer. The primary container has a primary bottom. The first insulation layer is disposed below the primary bottom. The secondary bottom is disposed below the first insulation layer and the secondary container. The secondary bottom has an expansion joint configured to permit the secondary bottom to expand and/or contract independently from the secondary container. The second insulation layer is disposed below the secondary bottom. In the event of LNG leaking from the primary container, the second insulation layer is protected from LNG contact by the secondary bottom. The carbon steel liner located on the outside face of the concrete wall remains vapor tight and liquid tight in the event of any amount of LNG leaking from the primary container.
