Abstract
System and method for repairing a pipeline comprising a first pipe wherein a second pipe is pushed in the first pipe by a first device into a first acces s point of said first pipe and wherein said second pipe is also pulled in said first pipe by a second device through a second access point.
Claims (35)
1. A system for rehabilitating a pipeline comprising a first pipe, said system comprising:
a first device coupled to a first portion of a second pipe, wherein said first device is configured to push a length of said second pipe into a first access point of said first pipe;
and a second device coupled to a second portion of said second pipe, wherein, said second device is configured to pull said second pipe through a second access point in said first pipe, said second access point spaced a distance from said first access point.
a first device coupled to a first portion of a second pipe, wherein said first device is configured to push a length of said second pipe into a first access point of said first pipe;
and a second device coupled to a second portion of said second pipe, wherein, said second device is configured to pull said second pipe through a second access point in said first pipe, said second access point spaced a distance from said first access point.
2. The system of claim 1, wherein said first device is an injector or a reel.
3. The system of claim 2, wherein said second device is a capstan, winch, tractor or propulsion jet.
4. The system of claim 1, wherein said second device is a capstan, winch, tractor or a propulsion jet
5. The system of claim 4, wherein said second device is a capstan.
6. The system of claim 5, wherein said capstan is connected to said second pipe with a rope.
7. The system of claim 4, wherein said first device is an injector or reel.
8. The system of claim 1, wherein said first pipe is flooded with a fluid.
9. The system of claim 8, wherein said second pipe has about neutral or minimal negative buoyancy in said fluid.
10. The system of claim 8, wherein said fluid is at least one of a brine and a water-based drilling mud.
11. The system of claim 8, wherein said fluid further comprises a friction reducing fluid.
12. The system of claim 8, wherein said second pipe further comprises a buoyancy control layer.
13. The system of claim 12, wherein said buoyancy control layer is coupled to an exterior of said second pipe.
14. The system of claim 13, wherein said buoyancy control layer has a specific gravity in water of less than about 1.25 g/cm3.
15. The system of claim 12, wherein said buoyancy control layer is as extruded layer on the exterior of said second pipe.
16. The system of claim 12, wherein said buoyancy control layer is deposited on the exterior of said second pipe.
17. The system of claim 15, wherein said buoyancy control layer comprises a thermoplastic foam.
18. The system of claim 1, wherein said second pipe further comprises a buoyancy control layer.
19. The system of claim 18, wherein said buoyancy control layer reduces the coefficient of friction of the exterior of said second pipe.
20. The system of claim 19, wherein said buoyancy control layer comprises a thermoplastic foam.
21. The system of claim 1, wherein a transmitter is mixed to said second pipe to monitor the advancement of the second pipe in the first pipe,
22. A method of rehabilitating a pipeline comprising a first pipe, the method comprising inserting a second pipe into said first pipe; and simultaneously pushing and pulling a length of said second pipe through said first pipe.
23. The method of claim 22, further comprising flooding the first pipe with a fluid.
24. The method of claim 23, further comprising providing said second pipe with a buoyancy control layer.
25. The method of claim 24, wherein providing said second pipe with a buoyancy control layer includes extruding a layer on the exterior of said second pipe.
26. The method of claim 24, wherein providing said second pipe with a buoyancy control layer includes wrapping a layer about the exterior of said second pipe.
27. The method of claim 24, wherein said buoyancy control layer comprises a thermoplastic foam.
28. The method of claim 23, further comprising selecting a fluid such that said second pipe has about neutral or minimal negative buoyancy in said fluid.

33. The method of claim 32, further comprising connecting a capstan to an end of said second pipe by a rope, and operating said capstan to pull said second pipe through said first pipe.
34. The method of claim 33, wherein said injector and said capstan communicate with each other to control the pushing and pulling.
35. A method of rehabilitating a pipeline comprising a first pipe, the method comprising:
inserting a second pipe having a buoyancy control layer into said first pipe, said buoyancy layer comprising a layer of material having a density selected to provide a desired buoyancy to said second pipe; and simultaneously pushing and pulling a length of said second pipe through said first pipe.
35. The method of claim 35, wherein said buoyancy control layer has a specific gravity in water of less than about 1.25 g/cm3.
37. The method of claim 35, wherein said buoyancy control layer comprises an extruded layer on the exterior of said second pipe.
38. The method of claim 35, wherein said buoyancy control layer is deposited on the exterior of said pipe.
39. The method of claim 37, wherein said buoyancy control layer comprises thermoplastic foam.
40. The method of claim 35, further comprising flooding the first pipe with a fluid.
inserting a second pipe having a buoyancy control layer into said first pipe, said buoyancy layer comprising a layer of material having a density selected to provide a desired buoyancy to said second pipe; and simultaneously pushing and pulling a length of said second pipe through said first pipe.
35. The method of claim 35, wherein said buoyancy control layer has a specific gravity in water of less than about 1.25 g/cm3.
37. The method of claim 35, wherein said buoyancy control layer comprises an extruded layer on the exterior of said second pipe.
