PUBLIC ABSTRACT The project will monitor those sections of pipelines in potential geohazard locations and then use the results to (i) gain insights into improving pipeline risk modeling, and (ii) develop fact-based monitoring solutions in geohazard prone locations. SUMMARY AND CONCLUSIONS The project developed a fiber-optic based multi-sensor monitoring system utilizing Distributed Strain Sensing (DSS), Distributed Temperature Sensing (DTS), and Distributed Acoustic Sensing (DAS) and installed them on two pipelines and laboratory tested at two locations. The DTS system was tested using heat tape during and after the installation of the optical cable, and the system performed very well. The DAS sensor system detected both the calibration taps and the noise from the gas leak. The DSS did not perform well.
