Efficient High-Performance with Sliding Concrete Walls and Integrated Liner
Composite concrete cryogenic (C3T) walls are constructed of prestressed concrete panels that are vertically prestressed and circumferentially wrapped with prestress wires encased in shotcrete. A non-structural carbon steel liner, whose sole function is to provide a liquid and vapor barrier, lies between precast, prestressed panels and the shotcrete layer. The liner is under biaxial compression and not in direct contact with the LNG, which makes it less susceptible to thermal shock.
