Benchmarking, Pig Tracking, and Dig Staking

Bolin Enterprises helps our customers maintain the integrity of their pipelines with our Benchmarking, Pig Tracking, and Dig Staking services. Our reliable methods help prevent costly mistakes. With more than 30 years in the industry, Bolin has experience you can trust..

Benchmarking

Benchmarking and establishing accurate and repeatable Above Ground Marker (AGM) locations are crucial steps for maintaining the integrity of your pipeline. These allow for the successful investigation of anomalies identified by the In-Line Inspection (ILI) Tool. Bolin Pig Tracking and Benchmarking technicians are highly skilled and understand the importance of accurate benchmarking and documentation prior to the tool run and box deployment and activation during the tool run.

Successful deployment and accurate placement of AGMs results in efficient measurement and marking of the anomalies to be investigated, whether tape-chained in or through the use of GPS coordinates from the ILI Tool vendor. Taking this step can save you tens of thousands of dollars by increasing the efficiency of the excavation crew and inspector.

Bolin Benchmarking and Pig Tracking technicians gather sub-centimeter GPS coordinates for the benchmarked locations and follow our customer’s policies for establishing, marking, and identifying the benchmark location.
