Monitoring the spatial position of the pipeline is one of the objectives of the integrity maintenance program. Landslides, ground movements in permafrost conditions, and seismic activity are just some of the causes of pipeline displacement and, as a result, the appearance of strain areas.
The XYZ surveys offered by NGP are performed by means of high-precision navigational equipment of its own design. The mapping inspection can be carried out as a part of caliper survey as well as during the inspection with the magnetic or ultrasonic inspection tools. As a result of the survey our Customers receive accurate data about the spatial location of the pipeline used, among others, for the assessment of the stress condition of the pipeline segment.
XYZ final report also contains coordinates of defects and features of the inspected facility, which makes localization on site during verifications and repair works easier.
