Importance of Management of Change in Alarm Modifications

February 2016, Vol. 243, No. 2

For process plants and gas pipeline networks, it is essential to manage change when making modifications to alarms and alarm systems. Management of change (MoC) should, therefore, be a fundamental process within the alarm management lifecycle. It is widely recognized throughout the process industries that making changes to assets can be prone to error. This is equally true for energy pipelines and managing alarms across a distributed network of pipelines, often over vast distances with multiple aboveground installations (AGIs). Indeed, some pipeline accidents and incidents have been attributed to poorly executed or unapproved changes. Making […]

Mobile Inspection Forms Cut Time, Maximize Accuracy of Audits

February 2016, Vol. 243, No. 2

Recordkeeping increasingly is the linchpin for the safe, reliable construction and operation of energy pipeline systems. In both the aftermath of natural gas pipeline incidents and in the attempts to develop a more sophisticated safety culture that employs technology advances to expand preventive maintenance, accurate, up-to-date and accessible inspection records are a risk-management necessity. This has required a technology and a mindset transformation of sorts for the oil and gas industry. Emerging from more recent federal and state regulatory responses to pipeline failures, some catastrophic in their effects, there has been a renewed emphasis on […]

Top 10 Cybersecurity Vulnerabilities for Oil and Gas

February 2016, Vol. 243, No. 2

With the exploitation of new cost-effective operational concepts, use of digital technologies and increased dependence on cyber structures, the oil and gas industry is exposed to new sets of vulnerabilities and threats. Cyberattacks have grown in stature and sophistication, making them more difficult to detect and defend against, and costing companies increasing sums of money to recover from. DNV GL recently delivered a study to the Lysne Committee that reveals the top ten most pressing cybersecurity vulnerabilities for companies operating offshore Norway. They are also applicable to the industry at large. An  international DNV GL […]

Does Aligning Cybersecurity, Process Safety Approaches Reduce Risk?

February 2016, Vol. 243, No. 2

Cyber-attacks are more hostile and frequent than ever. We’ve all heard news stories about how intellectual property and private information have been stolen by hackers. When this happens, it can be costly in some cases and embarrassing in others. However, for industrial operations, the stakes are much higher. It is absolutely essential we protect industrial operations from cyber-interference to avoid any compromise to the safety and security of the plant, its people and the environment. A recent news story published on Bloomberg.com described a 2008 explosion at an oil pipeline, identifying a cyber-attack as the […]

AP Investigation: US Power Grid Vulnerable to Foreign Hacks

SAN JOSE, Calif. (AP) — Security researcher Brian Wallace was on the trail of hackers who had snatched a California university’s housing files when he stumbled into a larger nightmare: Cyber-attackers had opened a pathway into the networks running the United States power grid.

Retrofitting Customized Valves, Actuators for Pipeline Monitoring Stations

November 2015, Vol. 242, No. 11

Oil and gas engineers face a major problem in accurately and reliably measuring and monitoring the various fluids that are introduced into oil pipelines from well site pumping stations. A thorough understanding of both the oil separation process and the properties of valves and actuators is required to correctly specify a system that will sufficiently measure and monitor these various types of fluids. Also, the conditions downstream from each well are different, requiring valves and actuators to be highly customized to their specific role in the process.

Appalachian Midstream Operators Face Myriad of Challenges

November 2015, Vol. 242, No. 11

This has been a busy year of new challenges and issues facing the Appalachian oil and gas industry as rig count in the Appalachian Basin and elsewhere is down substantially compared to the previous two years.

A significant challenge ahead for shale developers in a lower price environment is to continue to be active in finding land, drilling wells and getting the natural resource to market. This article concerns our most recent report, published in May, on the issues and challenges facing midstream operators in the Appalachian Basin.

ROSEN Rolls Out Mobile Pipeline Diagnostics Units

ROSEN rolled out its much-anticipated R3 Service – which stands for responsive, rapid and reliable – before a large gathering of inquisitive industry executives and operators Oct. 28 in Houston.

At the center of the new service is a fleet of high-end mobile diagnostics units capable of carrying all the diagnostic equipment necessary to sites throughout the United States.

New Integrity Solutions Facing Many Same Old Problems

October 2015, Vol. 242, No. 10

The protection of oil, gas and refined product pipelines against natural events such as earthquakes, hurricanes and tsunamis, not to mention human actions including construction excavations, illegal tapping and terrorist sabotage, is an ongoing concern for operators around the world.

However, in the United States, the top three causes of pipeline failure reported by the Pipeline and Hazardous Materials Safety Administration (PHMSA) are construction excavations, corrosion and equipment failure (Figure1).
