Pipeline Mapping Services: We offer pipeline mapping services worldwide and provide services ranging from field mapping to high accuracy GPS networks that enable high quality adjustment of the in-pipe intertial navigation data.

Pipeline Mapping is a specialised part of Merrett Survey Partnerships worldwide survey services. As well as data collection in the field, we offer data processing services and act as consultants, providing training for pipeline operators in GPS, Survey and Geodesy.

Merrett Surveys have vast experience providing GPS surveys for AGM (Above Ground Marker) locations associated with IMU based pipeline mapping. We have skills to optimise the accuracy of your mapping system. Detailed reports enable crews to set out AGM's accurately and swiftly.

Field mapping required before the design of oil, gas and petroleum pipelines 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.

Prior to (or after) construction of a pipeline, an airborne LiDAR survey allows for the identification of off-line concerns such as rivers, streams, ditches and buildings and provides an accurate portrayal of ground conditions along the pipeline.

We also provide terrestrial laser scanning services, laser scanning is often used in oil and gas plants for clash detection.

We also provide pipeline asset surveys and can incorporate this data into a GIS for a variety of uses such as class location risk analysis. 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.
