Pipeline movement describes any change in a pipeline’s position, alignment, or curvature — caused by soil settlement, thermal expansion/contraction, seismic events, landslides, erosion, or third-party construction activity.

Pipeline movement describes any change in a pipeline’s position, alignment, or curvature — caused by soil settlement, thermal expansion/contraction, seismic events, landslides, erosion, or third-party construction activity. Undetected pipeline movement can lead to excessive bending strain, coating damage, joint failure, and ultimately pipeline rupture.

Monitoring pipeline movement is a critical component of integrity management, particularly for pipelines crossing geotechnically active areas, river crossings, or slopes. Traditional monitoring methods require excavation or ground survey — both expensive and disruptive.

EMPIT’s CMI technology enables non-invasive pipeline movement tracking through repeated aboveground surveys. By comparing high-resolution 3D pipeline position data over time, CMI identifies displacement, curvature changes, and strain accumulation — providing early warning of structural risk. Movement data feeds directly into operators’ integrity management systems for risk-based maintenance planning.
