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.

SCADA Operations Controlled Remotely

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.

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.

Lawmakers Urge US Agency to Bolster Pipeline Cybersecurity

Two Democratic lawmakers urged the Department of Homeland Security to better protect U.S. oil and gas pipelines from cyber-attacks, after a report they requested detailed a lack of federal oversight of the critical conduits.

Government

Change of Class Location Draws Opposition Citizen organizations and state regulators are opposing interstate pipeline efforts to convince federal regulators to provide an alternative to the class location system, which requires pipelines to take steps when there is population growth around a pipeli..

Assuring Integrity of Polyethylene Gas Pipeline Systems

To maximize benefits, gas transporters continue to push polyethylene pipe design with more demanding applications, larger diameters and higher operating pressures. The risk of rapid crack progression and variables affecting performance must be considered when increasing the diameter and wall thickness of PE pipe.

Columbia Gas’ Merrimack Valley Accident: Fallout Just Starting

Federal and state agencies immediately jumped into action to uncover causes and preventative lessons that might be learned from the fatal September explosions, but other investigations could have implications for pipeline operations far beyond Massachusetts.

Senstar

Senstar introduced the FiberPatrol FP7000 fiber-optic pipeline integrity monitoring system for both gas and liquid-carrying pipelines. It can also be used for fence-mounted intrusion detection.

Interstate natural gas transmission companies are committed to minimizing methane emissions. This article explains methane emission sources for the transmission and storage sector and the basis for emissions commitments that INGAA members have voluntarily adopted.

GE's Avitas Gains First BLVOS Approval after Shell Oil Study

Avitas Systems, a GE venture, received the first civil approval to fly an unmanned aerial vehicle with radar beyond visual line of site (BVLOS) after a successful study with Shell Oil, marking an important step toward long-range pipeline monitoring with drones.

Thermon

Thermon introduced its TraceNet™Genesis Control & Monitoring System, a new solution for managing heat-trace circuit performance on process lines, tanks and instrumentation. The system allows instant access to comprehensive information, including circuit performance history, fault analysis, and circuit drawings.

A review of the four main leak detection methods and their abilities to overcome the unique challenges of crude oil gathering networks and produced water pipelines.

Drones: Flights of Fancy or Future of the Energy Industry?

As wildfires again ravaged much of California and other western states, energy industry responders could hardly imagine how their counterparts dealt with similar disasters just a few years ago without drones.

Strategy Shaped by Volatility

Among major supply factors, deferred maintenance continues to challenge global production. Maintenance is especially critical in basins with aging asset infrastructure, as recently evidenced by the crack in the North Sea Forties pipeline.

Insuring Against Liabilities Can Be Tricky

Despite the great overall success of the American energy industry, problems do exist and happen on a near-daily level. While rail accidents occur with more regularity, pipeline spills can actually have more devastating effects.

Leak Detection Going to the Dogs

Dogs can perform a multitude of services including protection, therapy, rescue, and tracking to name a few. They can be trained to detect virtually anything, including pipeline leaks.

Pipe Pressure Before Explosions was 12 Times too High

The pressure in natural gas pipelines prior to a series of explosions and fires in Massachusetts last week was 12 times higher than it should have been, according to a letter from the state's U.S. senators to executives of the utility in charge of the pipelines.

Official: Pressure Sensors Focus of Gas Explosions Investigation

The investigation into the Boston-area natural gas explosions is partially focused on pressure sensors that were connected to a gas line that was being taken out of service shortly before the blasts, the head of the National Transportation Safety Board said.

California Jury Finds Plains All American Guilty in Oil Spill Trial

A California state jury found Plains All American Pipeline guilty of criminally fouling state waters or harming wildlife in a 2015 oil spill along the Pacific Coast.

Pipeline Digs Get Assist From PMO

Performing direct assessments to verify a pipeline’s MAOP is not new, but as federal regulations become more stringent, the volume of digs will increase significantly, and operators need to keep up with the pace.

More Skin in the Game: New Technology to Find, Fix Leaks

Technology has not only helped re-energize the natural gas sector of the global energy economy, but also led to safety advancements, such as methane-detection systems continuously monitor and alert operators to a significant leak.
