In this month’s Editor’s Notebook, Editor-in-Chief Michael Reed examines the latest legal turn for Enbridge’s Line 5 after an appellate court ruling sent the case to the U.S. Supreme Court, where observers expect a more favorable outcome for the pipeline.

Contributing Editor Stephen Barlas examines how PHMSA is pursuing regulatory changes that could ease pipeline safety requirements. The agency has issued three advance notices of proposed rulemaking as part of the Trump administration’s broader effort to reduce compliance burdens on the energy sector.

Explore how machine learning can help pipeline operators detect and predict metal loss when inline inspection data is unavailable. By analyzing 28 pipeline parameters, researchers developed models that achieved high accuracy in classifying corrosion and predicting depth, providing a promising tool for managing difficult-to-inspect pipelines.

Germany plans to accelerate gas pipeline construction to secure energy supplies for both civilian and military needs. Despite growth in hydrogen infrastructure, reliance on imported natural gas keeps pipelines central to the country’s energy strategy.

Coriolis flow meters provide unmatched accuracy for measuring liquids, gases, and slurries, even under changing viscosity, density, and temperature. Their versatility and low calibration needs make them ideal for demanding oil, gas, and industrial applications.

Mexico confronts a striking energy paradox: increasingly importing oil and gas despite vast domestic resources. Policy challenges, investment barriers, and regulatory issues prevent development of the nation's own supplies, creating opportunities for LNG exports while maintaining import dependence.

Haynesville is undergoing major pipeline expansion as Gulf Coast LNG projects drive record U.S. gas demand. New projects from Momentum, Williams, DT Midstream and others are slated for completion in 2025, boosting takeaway capacity to Louisiana export hubs.

TurkStream, the only major Russian pipeline still delivering gas to Europe, faces an uncertain future as the EU pushes to phase out Russian gas imports by 2027. Analysts warn outcomes could range from extended Turkey-Russia cooperation to the pipeline becoming a stranded asset.

Canada is ramping up oil and gas pipeline construction, including the Trans Mountain expansion and Coastal GasLink, to reduce reliance on U.S. markets and expand exports to Asia while strengthening national energy security.

The Chelsea River Crossing project in Boston marked a turning point for micro-tunneling, with contractors overcoming boulders, groundwater challenges, and long drives to achieve several industry firsts in pipeline construction.

Offshore pipeline risers face extreme fatigue challenges, especially at girth welds. Resonance testing is proving to be a powerful method to verify weld durability and improve the reliability of offshore pipeline systems.

Pipeline & Gas Journal highlights major developments across the global midstream sector, from offshore pipeline approvals in Brazil and expansions in British Columbia to LNG growth in the U.S., Mexico, and Asia. These updates reflect the steady pace of investment in gas infrastructure to meet rising energy demand worldwide.

Decom Engineering has developed the ultra-light C1-16UL chop saw for subsea operations, capable of cutting risers and mooring chains under extreme conditions. The tool’s lightweight design allows efficient ROV deployment, offering improved manageability and performance for offshore projects.

EnerMech has secured a contract from ExxonMobil to deliver a full flowline decommissioning package at the Hoover-Diana development in the Gulf of Mexico. The project marks EnerMech’s first major decommissioning campaign in the region, involving subsea flushing, pigging, and nitrogen operations to safely retire deepwater infrastructure.
