Hydrostatic Testing

Hydrostatic testing of pipelines is part of Buckeye’s Integrity Management Program.

Pipeline companies have conducted hydrostatic testing for decades as one method to identify defects or damage to the pipeline that could potentially cause a pipeline leak. A hydrostatic test is a routine test to ensure the integrity of our pipeline. The information below outlines the hydrostatic testing process.

1. The petroleum inside the pipeline is removed and replaced with water. This water contains an environmentally safe green dye to aid in determining the location of a defect, in the event of a leak.

2. The water inside the pipeline is pumped up to a pressure much higher than the normal operating pressure of the pipeline while transporting petroleum. This high pressure is typically held for at least 8 hours.

3. During this test, which will likely occur during the late evening and early morning hours, Buckeye representatives will be conducting visual inspections along the pipeline route. Each Buckeye employee will be wearing a hard hat and will carry a Company Photo Identification Card for safety and identification purposes. If you have any questions, please do not hesitate to speak with one of our representatives.

4. In the event of a sudden leak of water from the pipeline, the pressure will be reduced rapidly and the green water should rise to the surface quickly.

5. In the event of a small leak of water from the pipeline; the pressure will be reduced slowly and the green water may not immediately reach the surface. To locate the leak, Buckeye will excavate the pipeline at determined locations for further investigation and testing protocols.

6. In the event that defects in the pipeline are identified, repairs will be made as soon as possible and the testing will continue until the pressure remains intact for at least 8 hours.  

7. Following the successful completion of the hydrostatic test procedures, all of which is in accordance with U.S. Department of Transportation / Office of Pipeline Safety regulations, the water will be removed from the pipeline. The pipeline will be refilled with petroleum products and the petroleum distribution service to the area will be resumed.

Buckeye is committed to the continued safe operation of its pipelines and ensuring  the efficient and reliable transportation of petroleum products that America needs. Buckeye’s primary focus during any pipeline activity, including hydrostatic testing, is Public Safety and protecting the environment.
