The rescue tool is designed to provide in-line assistance to the inspection robot in case of malfunction or problems with battery supply or wireless communication. The rescue tool was demonstrated at Con Edison’s Van Nest facility in October 2016. This activity was successful in that the rescue tool operated as expected to pull the main robotic platform, weighing 1,500 pounds and simulated as stranded, from a 20-inch pipeline.

The technology addresses one of many challenges faced during in-line inspections with tetherless inspection platforms. Full visual and testing instrument access and inspection platform removal are key for proper inspection of the interior of a pipe.

Reduced Operations Cost - In-line inspection is one of the primary methods to ensure pipelines are free of defects or to identify those in need of corrective action. This rescue tool provides inspection personnel with an increased reliability by ensuring the inspection platform can successfully perform its task and be recovered for future use.

Greater Reliability -
