We determine the pipeline’s depth-of-cover using a variety of instruments which are coordinated via differential GPS to provide the X-Y-Z location of a pipeline and the topography above it. This is a Safety Inspection of pipelines so that Pipeline Operators are given the confidence of knowing that their lines are covered and safe to the public.
It is an Abnormal Operating Condition (AOC) to have exposed or suspended pipelines at navigable waterways or on shore near the banks. Our survey will gather information from sources to help us determine the difference between burial depth and the natural elevation of the land around it. That difference is the depth-of-cover.
As operators require the Depth-of-Cover surveys with their 5 year DOT surveys, we are a unique provider of these across waterway crossings.
