Support structure for shortened cryogenic transport trailer
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.
1. A cryogenic dewar comprising:
an inner tank;
an outer tank; and
a plurality of trunnion mounts,
wherein front trunnion mounts of the plurality of trunnion mounts are coupled between a front half of the inner tank and a front half of the outer tank, and
wherein rear trunnion mounts of the plurality of trunnion mounts are coupled between a rear half of the inner tank and a rear half of the outer tank;
a support stiffener coupled between a first portion of an inner surface of the inner tank at a first trunnion mount of the front of trunnion mounts and a second portion of the inner surface of the inner tank at a second trunnion mount of the front of trunnion mounts;
a reinforcement element connected to the support stiffener and extending away from the first trunnion mount to a further area of the inner surface of the inner tank outside of the first portion of the inner surface;
the first trunnion mount comprising a plurality of pie-shaped reinforcing pads welded to each other and to an outer surface of the inner tank to reinforce a connection of the first trunnion mount to the outer surface of the inner tank, the pads spaced from each other to provide a welding area therebetween to strengthen the connection of the first trunnion mount to the inner tank; and
a doubler support at a base of the first trunnion mount on the pads and peripheral to the first trunnion mount to support the first trunnion mount.
2. The cryogenic dewar of claim 1 , wherein a top trunnion mount of the front trunnion mounts and a top trunnion mount of the rear trunnion mounts are mounted between a top of the inner tank and a top of the outer tank, wherein a bottom trunnion mount of the front trunnion mounts and a bottom trunnion mount of the rear trunnion mounts are mounted between a base of the inner tank and a base of the outer tank, wherein a road side trunnion mount of the front trunnion mounts and a road side trunnion mount of the rear trunnion mounts are mounted between a road side of the inner tank and a road side of the outer tank, and wherein a curb side trunnion mount of the front trunnion mounts and a curb side trunnion mount of the rear trunnion mounts are mounted between a curb side of the inner tank and a curb side of the outer tank.
3. The cryogenic dewar of claim 1 , wherein the first trunnion mount is located on a road side of the cryogenic dewar and the second trunnion mount is located on a curb side of the cryogenic dewar.
4. The cryogenic dewar of claim 1 , wherein the inner tank and the outer tank are aluminum tanks.
5. The cryogenic dewar of claim 1 , wherein one or more of the trunnion mounts comprise eight inch outside diameter aluminum tubing.
6. The cryogenic dewar of claim 5 , wherein the eight inch outside diameter aluminum tubing extends through at least a portion of a wall of the outer tank.
7. The cryogenic dewar of claim 1 , wherein one or more of the plurality of trunnion mounts comprise at least one fiberglass support.
8. The cryogenic dewar of claim 1 , wherein a length of a trailer upon which the cryogenic dewar is mounted is less than thirty-five feet.
9. The cryogenic dewar of claim 8 , wherein the trailer is an aluminum trailer.
10. The cryogenic dewar of claim 8 , wherein the trailer further comprises a hydraulic cryogenic off-loading system.
11. The cryogenic dewar of claim 1 , further comprising one or more patch plates coupled to the outer surface of the outer tank adjacent to each of the plurality of trunnion mounts.
