The mapping information is incorporated into the inspection data report and can be integrated into Geographical Information System (GIS). INS data combined with DGPS control points digitally builds a 3D virtual pipeline route tailored to XYZ coordinates of pipeline features and anomalies (longitude, latitude and altitude). The challenge of getting available pipeline information aligned and synchronized as well as mapping the pipeline route is met by running the in-line inspection tools with in-built Inertial Navigation System (XYZ Mapping Unit). These records have been prepared in different formats representing a huge volume of data in “chaotic” state. On the contrary other pipelines may have too many records that have been accumulating for decades. Thus the owners and operators of some of those pipelines are not sure where exactly the pipeline route is – they know exactly only where the pipeline starts and ends.ĭue to lack of this knowledge the pipelines can be easily damaged by third parties (for instance during excavation works). The history of construction and maintenance records may no longer be available. Pipelines need to be mapped – this is the axiom for the modern pipeline industry.īy now many pipelines that have been built within last 50 years are still in service. ![]() XYZ mapping data is synchronized with inspection run info into a single database that can be viewed, analyzed and represented using LIN SOFT package. We install INS units on any type of inspection tool, thus we combine XYZ mapping with geometry, corrosion or crack detection surveys performed with Caliper, MFL, TFI or UT inspection tools. LIN SCAN provides XYZ mapping services for all pipeline sizes.
