Seal Sensor Network for Point-of-Source Leak Detection


‘Advanced seals’, ‘gaskets’, and  ‘repair patches’ having integrated leak detection sensors are desired to provide capability for point-of-source leak detection across sealed fastened fittings having seals and gaskets, as well as across composite repair patches.  Example uses of advanced seals and gaskets include flanged fittings sealed having o-ring seals, matting surfaces sealed using gaskets, threaded fittings having compression fittings, and valve stem seals. There is a need for advanced seal sensor networks to detect leaks and monitor seal health in pipeline pumping stations, pipeline valves, and pipeline repairs. The seal sensor network could be made-up of seals having integrated sensors that are networked with the capability to communicate state-of-the-system status to distributed intelligent controllers that are placed in both populated and remote locations.  A distributed control architecture using localized control agents is envisioned to provide a robust system topography that does not have the single-point-of-failure vulnerability associated and linkage with centralized supervisory control systems.

Proposals are sought to study, develop and demonstrate new point-of-source leak detection techniques and seal sensor networks for use in hazardous material and gas transmission/distribution pipeline systems.  

Expected Phase I outcomes:

Phase I activities may include research into micro sensing technology capable of being integrated within seals, the development of conceptual designs for seal sensors, the definition of the supporting network topography, and a proof-of-concept prototype to demonstrate the feasibility of a select smart seal concept.

Additional activities in the Phase I report could include establishing whole solution costs, value calculations, detailed technical and market analysis of target applications, market research and analysis of additional potential applications. These activities are designed to provide justification towards a carry-on Phase II effort.

Expected Phase II outcomes:

Phase II outcomes may include product prototyping, testing then designing and building deployable systems followed by analysis/testing in field environments.
