The cryogenic dewar may further include one or more longitudinal stiffeners coupled to the inner tank at locations of stress that provide resistance to such stress. The inner vessel may include a combination of longitudinal stiffeners to allow the dewar to meet governmental imposed regulations on strength and safety of the dewar without increasing the weight of the dewar or to increase the amount by weight of cryogenic liquid that can be transported under governmental imposed regulations, or both, by, with the addition of longitudinal stiffeners, simultaneously increasing the grade of the material of the inner tank.

  • Publication number: 20230204160
    Abstract: A cryogenic dewar may include an inner tank and an outer tank. The cryogenic dewar may further include a plurality of trunnion mounts. A first four of the trunnion mounts may be coupled between a front half of the inner tank and a front half of the outer tank. A second four of the trunnion mounts may be coupled between a rear half of the inner tank and a rear half of the outer tank. The trunnion mount may be further strengthen with a plurality of pie-shaped reinforcing pads welded to each other and to an outer surface of the inner tank.
