This PHMSA SBIR focuses on the development of a Seal Sensor System. When combined with the Pipe and Repair Sensor System (proposed separately), this technology will allow for a Smart Pipeline Network having integrated sensor networks that provide for continuous real-time monitoring of leaks and system health. In this program, sensor-seals having both sealing and force sensing functionality, as well, as smart-seals having integrated leak detection micro-sensors will be further developed and adapted for pipeline use. Concepts and designs will be developed for a networked seal sensing system capable of sensing the pinpoint location of a leak or impending leak, as well as sensing state of the seals. In Phase I, the scope will include the development of a Seal Sensor System for use with petroleum-based liquids, with Phase II expanding the scope to include development of a system for use with natural gas. During this program a network topography and control architecture will be developed that provides for (non-centralized) distributed intelligent control without a single point of failure vulnerability. Expertise in local area processor-based networks and TCP/IP web-based networking will be used to develop system concepts for a wide area Smart Pipeline Network supported by existing internet infrastructure.
