Because pipeline corridors are linear, they often cross areas prone to landslides and land subsidence. Geotechnical changes threaten pipeline integrity by potentially causing strain  that exceeds allowable limits. There are techniques to monitor complex geotechnical soil conditions, potential pipe movement, and elevated strain at locations prone to soil displacement. GASCADE’s natural gas transmission pipeline system links suppliers and customers in Germany and is directly connected to major European transit pipelines and LNG terminals. Sections of GASCADE’s network prone to land subsidence have been monitored since pipeline construction. In a joint project, GASCADE and Baker Hughes investigated a 32-inch gas transmission pipeline using the latest ILI technology, including a comprehensive assessment of axial strain (AXISS technology) and bending strain (IMU-based measurement). Data from known, continuously monitored locations were compared to current and previous ILI data. Analysis of current ILI data to detect previously unknown locations affected by land subsidence is presented.
