The deposition of solids, such as asphaltenes, scale and wax, in production systems can cause challenges to oil and gas producers.

Operating, Installation Considerations For Pipeline Composite Repairs

Composite repairs are no longer new to the pipeline integrity world. A significant body of work has been developed over the last several decades characterizing their performance and developing guidelines for end-users.

Buried Pipe Failures Dependent on Soil Stiffness, Too

Performance limits and potential failures must be identified for buried pipe design. Chief among those are excessive deformations of the pipe, wall buckling and collapse.

Causes, Effects and Solutions for Damaged Pipelines

The United States has more than 2.5 million miles (4 million km) of pipelines dedicated to liquid and natural gas. Although many are unaware, this large network provides a lifeline to everyday activities like pumping gas, generating electricity and even heating a home.

Canadian Agency Determines Corrosion Caused 2018 Enbridge Gas Pipeline Blast

An explosion and fire in 2018 along an Enbridge Inc natural gas pipeline in northern British Columbia was caused by corrosion, Canada's Transportation Safety Board (TSB) said on Wednesday.

ExxonMobil Proposes Framework for Methane Regulations

ExxonMobil today released a model framework for industry-wide methane regulations that includes specific guidance related to transmission pipeline blowdowns between compressor stations.

Hot Tapping, Flow Stopping for Odd-Sized Pipes

Mainline Control Systems (MCS), in conjunction with Kleiss & Co., is offering utilities the technology and tooling to tap and stop flow on vintage piping materials and nonstandard-inch sized pipes.

Pipeline Integrity Management – Past, Present, Future

Before what was once a quiet middle-class suburban neighborhood in San Bruno, Calif. had cooled into silence, a decade-long response in the U.S. pipeline industry was already underway, focusing on the molecules making up modern large-diameter pipe and the densely populated areas in which these energy highways traverse.

AI Use in Improving Product Quality, Operational Processes

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.
