What is 'Pipeline Mapping'

Pipeline mapping using GPS and inertial navigation systems (sometimes called IMU - Intertial Mapping Unit, or INS) enables the accurate location of anomalies and pipeline defects detected in MFL intelligent pig inspection runs. This method will minimise dig time and costs when locating the defects and anomalies.

This work is often generated through pipeline safety regulatory requirements, necessitating in-line inspection, integrity analysis and risk assessment. Many pipeline operators will manage this data using GIS for managing their assets, planning mitigation strategies, and developing integrity plans. Pipeline mapping provides the backbone of such GIS databases, and it is vital that this field data collection is completed in a reliable and accurate way.

The pipeline mapping work is a vital part of any pipeline integrity management scheme. For pipeline operators working in USA, it will help compliance with DOT regulations such as "the Pipeline and Hazardous Materials Safety Administration's Rules on Pipeline Integrity Management in High Consequence Areas for Hazardous Liquid Operators (49 CFR Part 195)."

This website is managed by two GPS surveying companies - Controlwork LLC and Merrett Survey Partnership, who are specialists in the provision of GPS and survey support for pipeline mapping projects worldwide.

Pipeline mapping can also mean (of course) the field mapping required before the design of oil, gas and petroleum pipelines - which is a service we also provide. We can do this using aerial mapping with photogrammetry or airborne laser scanning - Lidar, or ground based in field GPS or DGPS methods.

It can also mean the mapping of assets for GIS database input. Sometimes referred to as database mapping, or GIS mapping.
