Pipeline Design, Operation & Maintenance (Pipeline Committee)

GPA Midstream’s Pipeline Design, Operation & Maintenance group is responsible for technical matters concerning pipeline design, operation and maintenance. The committee studies gas, liquid, and multi-phase flow pipeline design (mechanical, materials, instrumentation) including construction, testing, integrity, leak detection, welding practices, NACE requirements, regulatory compliance, mapping and GIS, optimization, and modification. The committee is also responsible for software used in pipeline design, including pipeline simulators and leak detection. Work includes pipeline pressure regulation, safety devices and control room operations but does not include pipeline custody transfer measurement, product sampling and analysis, material testing, permitting or gas distribution systems. This committee meets twice per year, usually in April and October. View the Pipeline Design, Operation & Maintenance Committee Charter.
