Pipeline Integrity Management

The common thread is an uncommon depth of experience.

Coffman Engineers works closely with our clients to provide a comprehensive integrity management program for their pipeline integrity from technology selection to process support and from data evaluation and defect assessment to dig sheet preparation and complete repair package documentation. If desired, Coffman will provide a complete turnkey solution, including project management of sub contractors involved with related activities such as cleaning, NDE, hot tapping, and repairs. We work with crude oil, gas, or product lines. We have extensive experience dealing with sub-sea and multi-diameter pipelines, "unpiggable" pipelines, and specialized cleaning techniques. We are able to provide the following pipeline integrity services to our clients:
