Assessing the integrity of nitrogen-filled pipelines with ILI tool runs
Assessing the integrity of idled lines can present unexpected challenges – particularly when it comes to running inline inspection (ILI) tools through the nitrogen that is used to monitor idle lines for leaks and as a blanket to protect them from corrosion.
How root cause analysis helps prevent future problems
It was a relatively straightforward redesign of some piping to improve the functionality of a metering and pig launching station. The project included designing a pressure equalization runaround – a one-inch line to divert product around a 16-inch valve to allow refilling of the pig trap. We developed the design to meet regulatory requirements, client standards and operations preferences, and provided the drawings to the client’s construction team. We supported the client during construction, helping to resolve a couple of issues and answering several questions along the way. But the runaround posed no problems.
