Site Documentation


PureHM can complete sub-decimeter above-ground marker (AGM) site documentation to improve inline inspection (ILI) anomaly location and analysis.

Improved AGM locations allows for more accurate ILI results

Through decades of pig tracking experience, PureHM has developed expertise in sub-decimeter site documentation of AGM locations. PureHM can accurately survey new AGM locations before an ILI project begins, or re-survey existing AGM locations to improve accuracy. Improved AGM location accuracy helps operators save money by improving the accuracy of ILI data, which ultimately reduces the cost of
post-ILI repairs. This service can be done in conjunction with the deployment of AGMs for remote tracking projects, or independent of an ILI project before it occurs.
