Geohazards

High-pressure gas pipelines often cross potentially unstable slopes under static and/or seismic conditions. Consequently, their structural integrity may be detrimentally affected by Permanent Ground Displacements (PGDs) due to landslides, leading to pipe failures. Since pipeline rerouting is often unfeasible due to various techno-economic...

Most operators are aware of the threat that geohazards present to pipelines routed through hilly terrain or subsidence areas and those at river crossings. A range of management systems and tools is available to investigate and address these risks. Climate change is having an increasing but unpredictable impact on the development of pipeline...

Over the past decade, CENIT has strengthened its risk-informed approach to managing pipeline geohazards, focusing on early warnings for hydrometeorological threats. With a network of 90 monitoring sensors along pipeline rights-of-way, the system provides near-real-time data on rainfall and river levels, enabling proactive responses. By integrating...
