Abstract

A vertical pipe deployment system that includes a flexible pipe deployed vertically in a non-linear manner. A first clamp couples to and supports the flexible pipe. A second clamp couples to the flexible pipe. The second clamp laterally changes a direction of the flexible pipe as the flexible pipe descends vertically between the first clamp and the second clamp.

First claim

What is claimed is:

1. A vertical pipe deployment system, comprising:
a flexible pipe deployed vertically in a shaft in a non-linear manner, wherein the flexible pipe comprises a first pipe section, a second pipe section, and a pipe connector that couples the first pipe section to the second pipe section;
a clamp, wherein the clamp is secured around the flexible pipe; and
a bolt, wherein the bolt secures the clamp to a wall of the shaft to enable the clamp to support weight of the flexible pipe in the shaft.

2. The vertical pipe deployment system of claim 1 , comprising:
another clamp, wherein the other clamp is secured around the flexible pipe; and
another bolt, wherein the other bolt secures the other clamp to another wall of the shaft to enable the other clamp to support weight of the flexible pipe in the shaft.

3. The vertical pipe deployment system of claim 2 , wherein:
the clamp is secured around the pipe connector in the flexible pipe; and
the other clamp is secured around the first pipe section in the flexible pipe.

4. The vertical pipe deployment system of claim 3 , wherein:
the clamp comprises:
a plate having an aperture, wherein the bolt is secured through the aperture to facilitate securing the clamp to the wall of the shaft;
arms that extend out from the plate; and
a connector plate secured to the arms, wherein the connector plate comprises a protrusion that matingly interlocks with a groove on the pipe connector to facilitate securing the clamp to the pipe connector; and

the other clamp comprises:
a wire loop disposed over the other bolt that is secured to the other wall of the shaft; and
a wire mesh connected to the wire loop and disposed around the first pipe section in the flexible pipe, wherein the wire mesh is configured to contract around the first pipe section due to weight of the flexible pipe to facilitate securing the other clamp to the first pipe section.

5. The vertical pipe deployment system of claim 3 , comprising:
a further clamp secured around the second pipe section in the flexible pipe; and
a further bolt, wherein the further bolt secures the further clamp to the other wall of the shaft to enable the further clamp to support weight of the flexible pipe in the shaft, wherein distance between the clamp and the other clamp differs from distance between the clamp and the further clamp.

6. The vertical pipe deployment system of claim 1 , wherein the flexible pipe is deployed vertically in the shaft to form a sinusoidal wave pattern.

7. The vertical pipe deployment system of claim 1 , wherein the flexible pipe is deployed vertically in the shaft to form a spiral pattern.

8. A vertical pipe deployment system, comprising:
a flexible pipe configured to be deployed vertically in a shaft in a non-linear manner; and
a plurality of clamps each configured to be bolted to a corresponding wall of the shaft and secured around the flexible pipe to facilitate supporting weight of the flexible pipe in the shaft, wherein each clamp in the plurality of clamps is vertically offset and laterally offset from a neighboring clamp in the plurality of clamps.

9. The vertical pipe deployment system of claim 8 , wherein the vertical offset and the lateral offset between neighboring clamps in the plurality of clamps are uniform along a length of the flexible pipe.

10. The vertical pipe deployment system of claim 8 , wherein the vertical offset and the lateral offset between neighboring clamps in the plurality of clamps are non-uniform along a length of the flexible pipe.

11. The vertical pipe deployment system of claim 8 , wherein:
a first clamp in the plurality of clamps is configured to be secured around a pipe connector in the flexible pipe; and
a second clamp in the plurality of clamps is configured to be secured around a pipe section in the flexible pipe.

12. The vertical pipe deployment system of claim 11 , wherein:
the first clamp in the plurality of clamps comprises:
a plate having an aperture, wherein a bolt is configured to be secured through the aperture to facilitate securing the first clamp to a corresponding wall of the shaft;
arms that extend out from the plate; and
a connector plate configured to be secured to the arms, wherein the connector plate comprises a protrusion configured to matingly interlock with a groove on the pipe connector in the flexible pipe to facilitate securing the first clamp to the pipe connector; and

the second clamp in the plurality of clamps comprises:
a wire loop configured to be disposed over another bolt that is secured to a corresponding wall of the shaft; and
a wire mesh connected to the wire loop, wherein the wire mesh is configured to be disposed around the pipe section in the flexible pipe and to contract around the pipe section due to weight of the flexible pipe to facilitate securing the second clamp to the pipe section.

13. The vertical pipe deployment system of claim 11 , wherein:
the pipe connector connects the pipe section to another pipe section; and
a third clamp in the plurality of clamps is configured to be secured around the other pipe section in the flexible pipe.

14. The vertical pipe deployment system of claim 13 , wherein distance between the first clamp and the second clamp differs from distance between the first clamp and the third clamp.

15. A method of deploying flexible pipe, comprising:
bolting each of a plurality of clamps to a corresponding vertical surface of a shaft such that each clamp in the plurality of clamps is vertically offset and laterally offset from a neighboring clamp in the plurality of clamps; and
deploying the flexible pipe vertically in the shaft in a non-linear manner at least in part by securing the flexible pipe to the plurality of clamps such that the plurality of clamps support weight of the flexible pipe deployed in the shaft.

16. The method of claim 15 , wherein deploying the flexible pipe vertically in the shaft comprises deploying the flexible pipe vertically in the shaft to form a sinusoidal wave pattern.

17. The method of claim 15 , wherein deploying the flexible pipe vertically in the shaft comprises deploying the flexible pipe vertically in the shaft to form a spiral pattern.

18. The method of claim 15 , wherein the flexible pipe comprises a plurality of pipe sections connected via one or more pipe connectors.

19. The method of claim 15 , wherein deploying the flexible pipe vertically in the shaft comprises:
securing a first clamp in the plurality of clamps around a pipe connector in the flexible pipe; and
securing a second clamp in the plurality of clamps around a pipe section in the flexible pipe.

20. The method of claim 19 , wherein:
securing the first clamp in the plurality of clamps around the pipe connector in the flexible pipe comprises matingly interlocking a protrusion on the first clamp with a groove in the pipe connector; and
securing the second clamp in the plurality of clamps around the pipe section in the flexible pipe comprises disposing the pipe section within the second clamp and using weight of the flexible pipe to contract the second clamp around the pipe section.
