Disclosed are systems and methods for a fluid transportation system having a first flexible tube with an inner wall. The fluid transportation system also has a second flexible tube with an outer wall. The second tube is located inside the first tube and a standoff is located between the inner wall of the first tube and the outer wall of the second tube. The first flexible tube is configured to transport a first fluid and the second flexible tube is configured to transport a second fluid. The first and second flexible tubes are configured such that the first fluid isolates the second fluid from an ambient environment, and the first fluid can be monitored for leakage.

1. A fluid transportation system comprising: a first flexible tube having an inner wall and configured to transport a first fluid;a second flexible tube having an outer wall and configured to transport a second fluid, wherein the second tube is located inside the first tube;a standoff located between the inner wall of the first tube and the outer wall of the second tube;a distribution device comprising: a chamber comprising chamber walls that are configured to define a path for a flow of the first fluid through the distribution device, wherein the second end of the first flexible tube is coupled to the chamber and the first flexible tube is located external to the chamber,a first fluid port configured to provide an opening for the first fluid to enter the chamber, anda second fluid port, located external to the first fluid port, configured to provide an opening for the second fluid to enter the second flexible tube; anda manifold including: a first portion that is located inside the chamber, wherein the second end of the second flexible tube is coupled to the manifold and the second flexible tube is located external to the chamber; anda second portion that is located outside the chamber. 2. The system of claim 1, wherein the first and second tubes are configured in a rolling loop. 3. The system of claim 1, wherein the standoff extends substantially radially from the outer wall of the second tube to substantially center the second tube within the first tube. 4. The system of claim 1, wherein the standoff extends from the outer wall of the second tube toward the inner wall of the first tube. 5. The system of claim 1, wherein the standoff is fastened to both the inner wall of the first tube, and the outer wall of the second tube. 6. The system of claim 1, wherein the standoff is integral with the second tube. 7. The system of claim 1, wherein the standoff is integral with the first tube. 8. The system of claim 1, further comprising: a third flexible tube having a first end, a second end, and an inner wall configured to transport a third fluid, and fastened to the first tube;a fourth flexible tube having a first end, a second end , and an outer wall and configured to transport a fourth fluid, wherein the fourth tube is located inside the third tube; anda second standoff located between the inner wall of the third tube and the outer wall of the fourth tube, 9. The system of claim 8, wherein, the manifold is coupled to the second end of the fourth flexible tube, and the second end of the third flexible tube is coupled to the chamber of the distribution device. 10. The system of claim 8, wherein the third flexible tube and the fourth flexible tube are configured such that the third fluid isolates the fourth fluid from an ambient environment. 11. The system of claim 8, wherein the first end of the third flexible tube is configured to move relative to the second end of the third flexible tube. 12. The system of claim 1, wherein the standoff extends along the outer wall of the second tube, substantially parallel with a centerline of the second tube. 13. The system of claim 1, wherein first and second flexible tubes are configured such that monitoring of the first fluid detects a breach of the second tube. 14. The system of claim 1, wherein the first tube is fastened to the second tube. 15. The system of claim 1, further comprising a pressure monitor configured to monitor a fluid pressure in the first tube. 16. A lithographic apparatus comprising the fluid transportation system of claim 1. 17. The system of claim 1, wherein the first end of the first flexible tube is configured to move relative to the second end of the first flexible tube. 18. The system of claim 1, wherein the first flexible tube and the second flexible tube are configured such that the first fluid isolates the second fluid from an ambient environment.
