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.

Lawsuit: Poor information about pipeline led to fatal blast

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

Barely one year after the commissioning of East and Central Africa’s only refined oil transportation pipeline in Kenya, leakages have been reported, raising concerns about the ability of existing government agencies to monitor the safety of oil infrastructure at a time when similar projects have been unveiled across the region.

Slam-Shut Technology for Ultra-Low-Pressure Protection

Natural gas is an abundant fuel used for both industrial and residential energy and is one of the few energy sources delivered directly into our homes. Because it’s also a flammable, potentially explosive fluid, natural gas utilities and distribution companies are required to prioritize safety and devote focus to their protection systems to prevent over-pressurization accidents, even for systems operating at extremely low-pressure levels (< 1 psi).

Clean-Up of Polish Section of Druzbha Pipeline Could Take a Year

The operator of the Polish section of the Druzbha oil pipeline said on Tuesday that it could take up to a year to completely clean its part of the network.

Produced Water Spills into Missouri River Tributary

Cleanup is underway after 21,000 gallons of brine oilfield wastewater leaked from an underground pipeline in western North Dakota and into an unnamed tributary of the Missouri River, the state Health Department said Monday.

Flow Meter Provides Dual Measurements in Single Body

The Transus Instruments UIM-4F Duo natural gas custody transfer ultrasonic flow meter consists of two independent fiscal flow measurements in a single flow meter body, enabling enhanced condition-based diagnostics in a space saving, compact package.

Emerson

Emerson released the Micro Motion 4200 2-wire loop-powered Coriolis transmitter, a new design that makes it possible to replace existing two-wire flow devices with minimal effort and without incurring additional power or cabling costs. The device can accommodate the largest line size (4-inch) of any..

Looking to Lessen Fluctuating Flow Problems in Measurement

Good measurement practices suggest flow measurements should occur without instabilities or pulsations in the flow. Even minor inaccuracies in the measurement of high value products can lead to significant financial exposure over extended periods of time.

Using Computational Fluid Dynamics When Equipment Fails

The importance of accurate measurement cannot be under-estimated. In 2012, the oil price was above $100 per barrel, but only a year later, as oil prices began to decline, the average price of a barrel of crude oil was $91, dropping to $42 by 2015.

Pipeline Leaks Produced Water in North Dakota

About 8,400 gallons of produced water has spilled in Stark County, N.D., because of a pipeline leak, officials said.

Druzhba Pipeline Flows to Poland Resume after Shutdown

Oil flows to Poland through the Druzhba pipeline resumed on Thursday after being suspended on Wednesday evening due to the discovery of contaminated oil, Polish pipeline operator PERN said.

Ashcroft

The Ashcroft® T6500 stainless steel, solid front pressure gauge is now available with the XRA overpressure option. This feature adds an overpressure mechanism that restricts the motion of the Bourdon tube after the specified full-scale value is reached. As a result, the gauge can withstand up to 400..

Modeling and Prediction of Black Powder Erosion of Gas Pipelines

Black powder is composed of different forms of iron sulfide (FeS), iron oxides (Fe3O4, FeOOH) and iron carbonate (FeCO3), mechanically mixed or chemically combined with any number of contaminants, such as salts, sand, liquid hydrocarbons, metal debris, and even naturally-occurring radioactive material (NORM).

Reducing Leakage Risks Using Advanced Digitalization

Stricter regulations, price volatility, and emerging technologies are disrupting conventional operational approaches in today’s midstream pipeline industry; even transport demand has never been greater. Therein lie both challenges and opportunities.

Measuring Crack Defects with Sub-Millimeter Accuracy

Ultrasonic crack technology, using piezoelectric transducers, is a proven and widely used solution for crack and crack-like defect detection in liquids pipelines. Over the past 20 years, only minor developments and improvements in this area were offered to pipeline operators.
