This PHMSA SBIR focuses on the development of a new multi-channel cased in pipe design with internal support structure that will allow access along its entire axial length while adequately securing the carrier pipe to the containment pipe. When combined with the Seal Sensor System (proposed separately), this technology will allow a Smart Pipeline Network having integrated sensor networks that provide for continuous real-time monitoring of leaks and system health. In this program, concepts and designs will be developed for a multi-channel cased pipe design that improves monitoring and lends itself to the incorporation of networked sensing system capable of sensing the pinpoint location of a leak, as well as monitoring structural health. In Phase I, the scope will include the development of a cased multi-channel pipe for use with petroleum-based liquids, with Phase II expanding the scope to include development of a system for use with natural gas.
