Geotechnical hazards are ground-related risks that can cause pipeline movement, deformation, or failure — including landslides, soil subsidence, seismic activity, frost heave, soil liquefaction, river erosion, and slope instability.

Geotechnical hazards are ground-related risks that can cause pipeline movement, deformation, or failure — including landslides, soil subsidence, seismic activity, frost heave, soil liquefaction, river erosion, and slope instability. These hazards are a leading cause of pipeline integrity threats, particularly for buried pipelines crossing varied terrain.

Geotechnical risk assessment is essential during pipeline routing, design, and throughout operational life. Key concerns include differential ground settlement causing bending strain, slope movement displacing pipeline sections, and seismic loading exceeding design parameters.

EMPIT’s CMI technology directly addresses geotechnical pipeline risks through non-invasive aboveground inspection. CMI detects pipeline movement, bending strain, depth of cover changes, and out-of-straightness conditions — providing operators with precise data to monitor geotechnical threats and plan remediation. Repeated CMI surveys enable pipeline movement tracking over time, supporting risk-based decision-making for pipelines in geotechnically active areas.
