CODE-376-23 (SI Units): Refrigerated Liquefied Gas Containment for Concrete Structures—Code Requirements and Commentary

Abstract:

This code provides minimum requirements for design and construction of reinforced concrete and prestressed concrete structures for the storage and containment of refrigerated liquefied gases (RLG) with service temperatures between +40 and –325°F. The principles listed herein are applicable to concrete foundations of double-steel tanks subject to the approval of the owner. Container design shall include the design of the container wall, its foundation (footing and floor slab), the concrete portions of its roof, and the bund wall, whenever applicable. Available in hard copy or electronic format. Keywords: bund wall; commissioning; cryogenic; damage stability; decommissioning; earthquake design levels; fatigue; float out; floating storage unit; foundation heating; gravity base structure; impact loads; liners; liquefied natural gas; liquid stratification; permanent ballast; purging; refrigerated liquefied gas; reinforcement (cryogenic); tanks; thermal corner protection
