Indeed, recent studies have suggested overestimation of the pressure drop across a pipeline during design resulting in less...

These systems automatically stop the compressor units and isolate the section of the pipeline to limit environmental damage in the case of a pipeline rupture. Regulations require operators to periodically test compressor stations and maintain the emergency...
