Surface topography and pipeline route selection

Surface topography image and pipeline routes

Oil and gas pipeline routes are absolutely pivotal information. The route that a line has to take is always a trade-off between what you’d ideally like to have and what you have to accept: an ideal oil pipeline would run in a trench across a totally flat surface with constant temperature and no seismic activity. In real life, we have mountains, deserts, heat and cold fluctuations, seismic activity of all sorts, permafrost or rocky outcrops that necessitate raising the line on supports, and other obstacles. (And that’s without mentioning regulatory environment…)

On the one hand, knowing the terrain you have to get across lets you know what kind of pipeline you can have. On the other, knowing the pipeline plans lets you know what kind of geotechnical data you’re going to need to bring it home safely and efficiently.

When you’re researching pipeline route corridor alternatives, you’re equally faced with compromises. You need reliable, accurate surface topography data for the whole potential route corridor. Solid geotechnical data allows correct pipeline route selection and implementation, but getting it by traditional means is costly, time-consuming and environmentally damaging and can run the risk of damaging your local reputation.

PhotoSat elevation image and pipeline route options

 

PhotoSat’s highly accurate, engineering-quality digital surface topography allows you to examine and select multiple pipeline corridors and plan final routes, based on elevation data accurate to 30cm vertically. You can do it without risking survey teams in inaccessible locations or hostile environments. Usable engineering survey data is generated fast, typically within five days. We’ll typically supply our oil and gas clients with an engineering quality 1m topographic grid accurate to 30cm in elevation, 50cm or 1m contours, and a 50cm satellite ortho photo. And after it’s been used to select pipeline routes, the surface topography can be used for all phases of the project, because it’s accurate and comprehensive enough for most engineering tasks.

The accuracy of our surface topography has been proven in many accuracy studies using tens of thousands of ground survey points for comparison. View our proof of accuracy reports for more information. We have completed over 500 projects all over the world.
