What we do and where.

GPS surveyors for pipeline integrity management

Experience

Why wait for the problems to occur,
when we have the solutions already in place?

Through long experience (our own, plus supervising other surveyors worldwide) we have witnessed all the problems, and we know how to prevent them.

We have a detailed knowledge of the pipeline mapping process - how the pig works, the need for reliable high accuracy GPS, the correlation of in-line MFL data to above ground features. We have the experience to make the mapping work.
