Abstract:

The 2002 Office of Pipeline Safety (OPS) regulations requiring the inspection of all transmission pipelines, including those that are now deemed “unpiggable”, triggered the search for technologies that would make the inspection of unpiggable pipelines possible. This document presents the final report for a program focusing on the completion of the research, development and demonstration effort, which was initiated in 2001, for the development of two robotic systems for the in-line, live inspection of unpiggable transmission and distribution natural gas pipelines. Two robotic platforms have been developed and commercialized as a result of this effort: (a) Explorer II (Explorer 6-8), which carries a remote field eddy current (RFEC) sensor for the inspection of 6” and 8” unpiggable pipelines, and (b) Explorer 20-26 (TIGRE), which carries a magnetic flux leakage (MFL) sensor for the inspection of 20” to 26” unpiggable natural gas pipelines. This work allowed certain design enhancements for the Explorer II system, as identified through the field demonstrations that the systems underwent, as well as the development of commercial grade defect sizing algorithms for the RFEC sensor. This work also completed the development of the TIGRE system, a robotic device for the inspection of 20” to 26” unpiggable natural gas pipelines, which carries a magnetic flux leakage (MFL) sensor for the detection of defects. Through this program a series of five field demonstrations in dead and live pipelines was carried out, culminating with the commercialization of the technology.
