ASME International Pipeline Geotechnical Conference, Bogota
The pipeline risk factors associated with natural forces include:
- Landslides and mass movement
- Tectonics/seismicity — including fault crossings and liquefaction
- Hydrotechnical — including river scour and channel migration
- Erosion and upheaval displacement
- Geochemical — including karst and acid rock drainage
- Unique soil structure — including residual and sensitive soils
- Desert mechanisms — including dune migration
- Volcanic mechanisms
- Freezing of unfrozen ground
- Thawing of permafrost terrain
These forces have become critical in the integrity management of pipelines due to the occurrence of failures causing loss of human life and damage to the environment. These risk factors are known as Geohazards resulting from natural processes of a geotechnical, geological, hydrological, or tectonic origin that represent potential threats usually induced during the pipeline construction and operations.
