(P&GJ) — The Colorado Air Quality Control Commission (AQCC) recently adopted rules aimed at increasing repair inspections and leak detection at oil and gas facilities throughout the state. While these new guidelines do not affect midstream directly, there are implications for the sector due to the growing emphasis on carbon-capture and related pipelines.

(P&GJ) — The natural gas industry greeted the permitting reform bill Congress passed and President Biden signed with something short of enthusiasm to say the least.

By their nature, non-intrusive pig signallers do not require a nozzle hole for any type of welded fitting, whether it be a 'counter flange' or a direct fitting like a threadolet. They are simply secured to the pipeline. Simultaneously, this approach saves costs on welding, non-destructive testing, and eliminates the risk associated with potential hydrocarbon leak paths.

(P&GJ) — The U.S. Pipeline and Hazardous Materials Safety Administration (PHMSA) proposed a rule in May that included significant measures to reduce emissions from pipelines and other midstream infrastructure.

(P&GJ) — Following is a listing of some of the longest transportation routes on the continent of Europe as of July 2023. This third such report will be broken down into two sections, gas and liquids (oil and products), which will be updated in each of our September issues going forward.

(P&GJ) — Following the attack on the Nord Stream 2 Pipeline a year ago, NATO’s Secretary General Jens Stoltenberg discussed the protection of critical infrastructure with NATO’s members. He made a special point of reaching out to German leaders and to Denmark’s defense minister, since this is the country closest to the damage.

(P&GJ) — ASME B31.8, ASME B31.4, and CSA Z662 have well-deserved international reputations as best-in-class, evidenced by their frequent reference by documents within other jurisdictions. However, the standards don't contain explicit requirements to address the design, construction and operational challenges presented by transporting gaseous hydrogen at transmission pressures.

(P&GJ) — For linear projects such as pipelines, dealing with the unexpected should be expected. The best preparation for these surprises is to partner with a team structured for close collaboration between the real estate and engineering disciplines as well as everything in between.

(P&GJ) — Thermal flowmeters are riding the surge of gas flow measurement in both renewable and traditional natural gas applications, according to a new study from Flow Research, “The World Market for Thermal Flowmeters.”

(P&GJ) — An objective was to determine residual stress values corresponding to target probabilities, such as the 90th percentile. Every reference reviewed reported maximum stress levels, but only one-third of the references presented other residual stresses as they vary with position in the pipe.

(P&GJ) — Based on its R&D experience, Skipper NDT decided in 2019 to address pipeline geolocation and strain assessment using UAS. This effort has provided a 2.2-kg and a 160-cm wide embedded system that can be easily mounted on any UAS.

(P&GJ) — With the skyrocketing cost of fuel, the value of any mistakes made while loading and unloading liquid natural gas (LNG) carriers is increasing. This makes it even more important for plant and instrumentation managers to have access to the most accurate measurement tools.
