In one embodiment, a modular bi-level storage and transport assembly (MTA) includes an upper rigid layer and a lower rigid layer and an adjustable support mechanism, coupled to the upper and lower rigid layers. Furthermore, the support mechanism is operable to expand to increase the distance between the layers, expanding the MTA and forming a space for a containment vessel, and to contract to reduce the distance between the layers, collapsing the MTA.

In one embodiment, a method for restraining a containment vessel within a modular bi-level storage and transport assembly (MTA) includes placing a containment vessel between an upper and lower rigid layer of the MTA, using an adjustable support mechanism to collapse the distance between the rigid layers, restraining the containment vessel, and mating the MTA to a matching MTA.
