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 first trunnion mount of the plurality of trunnion mounts comprising a plurality of pie-shaped reinforcing pads welded to each other and to an outer surface of the inner tank by a plurality of welds 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, the plurality of welds being received in the welding area to strengthen the connection of the first trunnion mount to the inner tank.
2. The dewar of claim 1 further comprising 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.
3. 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 trunnion mounts and a second portion of the inner surface of the inner tank at a second trunnion mount of the front trunnion mounts;
a reinforcement element connected directly 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; and
wherein the first trunnion mount comprises 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.
4. The cryogenic dewar of claim 3 , 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.
5. The cryogenic dewar of claim 3 , 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.
6. The cryogenic dewar of claim 3 , wherein one or more of the trunnion mounts comprise eight inch outside diameter aluminum tubing.
7. The cryogenic dewar of claim 6 , wherein the eight inch outside diameter aluminum tubing extends through at least a portion of a wall of the outer tank.
8. The cryogenic dewar of claim 3 , 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 further comprises a hydraulic cryogenic off-loading system.
10. The cryogenic dewar of claim 3 , 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.
11. The cryogenic dewar of claim 3 , wherein the pads are spaced from each other to provide a welding area therebetween to strengthen the connection of the first trunnion mount to the inner tank.
12. The cryogenic dewar of claim 11 , further comprising 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.
13. The cryogenic dewar of claim 3 wherein the support stiffener comprises an L-shaped aluminum member.
