Depth of Cover Survey

Maintaining Depth of Cover over your pipeline is critical to the safety and overall risk profile of your pipeline. We have experience depth of cover surveyors to provide this service and allow you to see where you may have poor coverage or expose geotechnical issue that you were previously unaware of.

Topographical Mapping

When you get into hilly and mountainous terrain it is important to understand the true topography and elevation profile of your pipeline. Changes in elevation have a huge impact when running pigs as uphill topography can cause MAOP issues and downhill topography can result in tool over speed issues particularly in gas pipelines. We can survey and prepare topographical maps of you pipeline that help you with your pigging and integrity dig planning.
