Abstract:
A method for sealing a leak in a pipeline used to transport fluid includes positioning a sealing device within the pipeline, moving the sealing device through the pipeline to a leak location, and internally generating an inflation pressure to inflate the sealing device to substantially cover a leak opening and limit release of the fluid from the pipeline.
