PIPELINE LEAK SEALING SYSTEM AND METHOD

摘要

A system for sealing a leak within a pipeline for transporting fluid includes a sealing device that is deployable to seal the leak. The sealing device includes a flexible wall formed into a substantially tubular shape defining an opening, and an internal frame coupled to the flexible wall and configured to control a movement of the flexible wall by applying a force to the flexible wall, wherein the movement of the flexible wall moves the sealing device through the pipeline. The system also includes a sensor assembly configured to monitor a pipeline condition and send a signal representing the pipeline condition, and a control module configured to receive the signal and control the force applied by the internal frame based on the signal.
