INSAR MONITORING OF PIPELINE ROUTES

In this study, we discuss the use of InSAR-SBAS deformation time-series analysis as part of an early warning technique to monitor the safety of oil pipelines on different terrains. We focus on an oil spill in a wetland area and identify potential risks along a new pipeline route. We analyzed 153 RADARSAT 2 InSAR images for both sites. Our results show that the InSAR deformation monitoring can be used to investigate sites along pipeline routes. Integrating InSAR deformation measurements with existing geotechnical, thermal and climatic information will provide an early warning technique to prevent potential pipeline rupture in geologically risky areas. The 4-day InSAR rapid revisit from the RADARSAT Constellation Mission (RCM) will increase the acquisition for monitoring surface deformation along these high-risk pipeline routes.
