The present disclosure is directed to methods and systems for pipeline rehabilitation. The methods and systems disclosed herein permit the rehabilitation of long lengths of previously installed pipe and minimize the need for creating multiple access points to the pipeline. The disclosed systems and methods are particularly suited for rehabilitating buried and undersea pipelines or pipelines installed in areas of restricted access. |

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS FIG.
1 illustrates an exemplary embodiment of a system 10 for rehabilitating a pipeline comprising a first pipe.
The system 10 comprises a first device 12 that is configured to push a length of a second pipe 14 into a first access point 16 of the first pipe 18.
The system 10 further includes a second device 20 that is configured to pull the second pipe 14 through a second access point 22 in the first pipe 18.
The system 10 operates to push and/or pull the second pipe 14 through the first pipe 18.
During operation, the first pipe 18 acts as a conduit for installing the second pipe 14.
The second pipe 14, once installed, may be utilized to transport fluids in place of the first pipe 18, thereby rehabilitating the pipeline.
The exemplary system 10 permits the rehabilitation of the pipeline with a minimum number of access points in the first pipe 18 comprising the pipeline.
In the illustrated embodiment, for example, two access points 16, 22 are provided in the first pipe 18.
The systems and methods for pipeline rehabilitation described herein, including the exemplary system 10, are particularly suited for rehabilitation of buried and undersea pipeline and other pipelines in which access to the pipeline may be restricted.
In the illustrated embodiment, for example, the first pipe 18 comprising the pipeline is buried underground.
One skilled in the art will appreciate that the systems and methods described herein are not limited to buried or undersea pipelines but instead may be utilized to effect rehabilitation of any installed pipelines.
Likewise, the orientation of the first device 12 and the orientation of the second device 20 relative to the first pipe 18, and in the exemplary embodiment, relative to the ground, may be varied.
For example, the first device 12 and the second device 20 may be oriented to introduce the second pipe 14 at an angle proximate to 90° relative the first pipe 18 as illustrated in FIG.
1, at angle proximate to 0° (i
