Artificial intelligence (AI) will be one of the most transformative technologies for business in the next 10 years. Early demonstrations of the power of AI in speech recognition and autonomous driving should remove those doubts.
Asbestos Abatement in Pipeline Repair
There are millions and millions of feet of vintage pipelines in use throughout the United States with an exterior coating that contains asbestos. There is probably an equal amount of footage existing in out-of-use, idled or abandoned pipelines.
Managing Selective Seam Weld Corrosion as Part of Integrity Management Plans
The industry expects that all operators take a robust approach to integrity management, resulting in safe and reliable pipelines. One of the many known threats to pipeline integrity that must be explicitly addressed is Selective Seam Weld Corrosion (SSWC). This article explores ways of reliably assessing pipelines for the threat of SSWC and actively managing SSWC when it is an active threat.
Pipeline Liquids Safety Record Reflects Inroads, Areas of Concern
Nearly 98% of barrel miles in the United States are governed by pipeline safety management systems, according to the American Petroleum Institute (API). That, combined with greater public awareness, means that pipeline integrity and safety are under a greater degree of scrutiny than ever before.
In Situ Pipeline Coating – A Hidden Champion Comes Out Of Hiding
In situ pipeline cleaning and coating offers advantages over conventional methods, particularly if it is possible to coat multi-mile lengths of pipe at a time. Not only rehabilitation of lines suffering from corrosion or deposits, but also in situ internal coating of new lines can offer savings as well as results of high quality and durability.
Innovation Drives World Record Natural Gas Main Renewal
Drivers along the stretch of Central Avenue crossing the Garden State Parkway by the East Orange General Hospital in New Jersey would have noticed the construction crews, excavations, equipment and vehicles in the middle of the street. What he or she would not know is that the project underway was setting a world record.
Libya's El Feel Oilfield Shut Due to Valve Closure
Libya's El Feel oilfield has been shut down due to a valve closure, the head of the National Oil Corporation said on Thursday, in the second stoppage at the southwestern field in consecutive weeks.
How Rotating Equipment Enhances Efficiency in Pipelines
Today, pipeline operators face increasing challenges on multiple sides, from more complex regulatory processes to the need for safer and environmentally friend operations. Baker Hughes has introduced the NovaLT gas turbine family, which is pushing the boundaries of reliability, efficiency and operability in gas turbines range up to 27,000 Hp.
How to Readily Access Accurate Data in Pipeline Integrity Management
In my experience, there are two common complaints from pipeline operators, and they occur at two different stages of the pipeline – one during construction, and the other during operations – but they are at their core the same: access to readily accurate data.
Our World Is Moving – And So Are The Pipelines
Strain assessments and pipeline movement assessments allow operators to identify and mitigate threats presented by geohazards.
Building A Holistic Pipeline Integrity Program
While new pipelines continue to be constructed the world over, the vast majority of them were laid in the 40s, 50s and 60s, often in remote or isolated areas. Today, operators are constantly facing an uphill battle of maintaining infrastructure well past its shelf life.
PHMSA Publishes "Mega" Rule After Nearly A Decade of Work
U.S. transportation officials on Tuesday adopted long-delayed measures that are meant to prevent pipeline spills and deadly gas explosions but don't address recommended steps to lessen accidents once they occur.
Feds Recommend New Requirements After Natural Gas Disaster
Federal officials are recommending stronger nationwide requirements for natural gas systems following last September's natural gas explosions and fires in Massachusetts.

A federal lawsuit accuses a major pipeline company based in Georgia of failing to tell work crews where a major underground pipeline was located before they ruptured the line, touching off a deadly explosion in Alabama.
Hand-Held Device Coats Pipeline Field Joints to OEM-Standards
Tape wrap contends with higher technology pipeline joint coating solutions, in many contexts with a degree of success. Wrapped with skill, tape can offer the requisite protection a pipeline joint needs.
iPIPE Program Assisting in Detection of Pipeline Leaks
Jay Almlie, a principal engineer at the Energy and Environmental Research Center (EERC), talks with P&GJ about his involvement with the intelligent Pipeline Integrity Program (iPIPE), an industry-led consortium focused on advancing near-commercial, emerging technologies to prevent and detect gatheri..
East Africa’s Leakage Incidents Points to Detection Needs
