Unwanted Night Moves

Whenever the subject of internal corrosion in pipelines comes up, it rekindles some unpleasant memories from my extensive time as a pipeline company spokesperson. Being part of an emergency response team for over 12 years was rewarding in many ways, but there was always an uneasy feeling when the phone would ring in the middle of the night.

Damage Tolerance Testing of Small-Diameter Pipelines

Internal and external corrosion, as well as third-party damage such as dents and gouges, are the main causes of pipeline failures worldwide. When such damage is detected by direct inspection, or in-line inspection methods, a decision to replace, repair, or accept and monitor must be made.

Over-Pressure Protection for Natural Gas Distribution Systems

Over-pressure protection equipment, or systems, are critically employed to ensure a single point of failure cannot result in exceeding the system MAOP.

Houston-based Remote Operations Center (ROC) connects operators to their data and provides an offsite monitoring workforce that can improve efficiency while reducing risk. It is the only third-party provider solely focused on executing control center services for liquid and gas pipeline operators.

Combined Flaws Represent Key Danger to Pipelines

Sergey Zubin, chief engineer of Transneft Diascan, discusses the importance of detecting “combined flaws,” or those that occur in close proximity on the pipeline, with Pipeline & Gas Journal.

Advanced Analytics Can Help Boost Pipeline Performance

Leveraging existing operational data as well as new data sources available as part of a digital transformation can provide great opportunities to significantly improve performance through better asset reliability, efficiency and safety performance.

Section of Keystone Pipeline Shut Down after Leak

TransCanada Corp said a stretch of its Keystone crude oil pipeline from Nebraska to Illinois remained shut down on Monday after a leak was discovered last week near St. Louis, Missouri.

Remote, Real-Time Monitoring Prevents Potential Problems

With utilities adding more and more residential and commercial endpoints to their distribution systems, the need to prevent and detect leaks has never been more challenging – or more critical. Thankfully, advanced technologies have emerged that allow utilities to harness new capabilities such as data analytics and remote monitoring to stay on top of leaks and address them before they create significant safety issues.

Thieves Siphon Whole Pipelines; Mexico to Ship Gas on Trains

Fuel thieves in Mexico have grown so bold they are drilling illegal taps under warehouses in big cities and siphoning off the entire contents of pipelines, Mexico's President Andres Manuel Lopez Obrador said. He cited one pipeline carrying gasoline that thieves had drilled into so many times they had siphoned all the fuel in the duct.
