Pipeline displacement caused by natural phenomena, such as ground movement and elevation changes, compromises the integrity of a pipeline. Excessive tensile strain can cause a direct rupture of a pipeline, while excessive compressive strain can cause local wrinkling, often resulting in imminent buckling. Such deformations ultimately cause pipeline failures that results in lost product and environmental damage.

Due to its use of high-resolution INS data acquisition and ability to leverage leading-edge software products, NDT Global’s Atlas INS is the most reliable means of measuring changes in the shape of a pipeline caused by external forces. With a single Atlas INS inspection, a potential high-strain area can be located discriminating field bends.

Performing Atlas INS inspections periodically, ensures the monitoring potential displacement of pipelines enabling the alignment of two inspections (odometer distance adjustment) and direct Run-on-Run comparison of curvatures and strain to accurately pinpoint the location of the displacement. The pipeline displacement between the two INS inspections is obtained by comparing the vertical and horizontal strain at the same points on the pipe.

NDT Global has the ability to align two inspections to detect slight changes (≥0.10%) in the strain over time, and accurately pinpoint pipeline movement locations.
