Transco Pipeline Hydrostatic Testing

 Hydrostatic Testing

Hydrostatic pressure testing is one of several methods Williams uses to reconfirm the structural integrity and safety of its natural gas pipeline. Hydrostatic testing involves removing the natural gas from the line, then filling a pipeline segment with water until it is at a pressure that is higher than the pipeline will ever operate with natural gas. This allows Williams to validate the safe operating pressure of the pipeline and ensure that the line is structurally sound.

Schedule

In late August and September Williams will be performing hydrostatic testing of various segments of its Transco pipeline, including segments located in Louisiana, North Carolina, South Carolina, Georgia and Alabama.

 

Duration

Each test is expected to last about 15 hours. The pipeline pressure is continuously monitored for the duration of the test. You may also see Williams and/or contract personnel patrolling the pipeline right of way during the testing process.

 

Safety Precautions

Out of an abundance of caution, Williams is requesting for the general public to remain clear of the pipeline right of way when possible during the testing period. You may notice signage in the vicinity of the test warning pedestrians to remain clear of the pipeline right of way while the test is underway. In the event a problem occurs during a hydrostatic test, we will have personnel standing by to respond. Once the hydrostatic test is complete, the signage will be removed. Test water will be disposed of properly and the line will be returned to service.
