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, often used in oil
and gas plants for clash detection.

We carry out 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 use GIS for managing their assets,
planning mitigation strategies, and developing integrity
plans. Pipeline mapping provides the data for the GIS,
and it is vital that 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)." |
