Pipeline

Clean Energy Fuels has started injecting renewable natural gas into the pipeline from its $85 million South Fork Dairy facility in Texas. The project, one of the nation’s largest RNG plants, processes 300,000 gallons of manure daily and will generate millions of gallons of low-carbon fuel each year.

Targa Resources is acquiring Stakeholder Midstream for $1.25 billion, adding 480 miles of Permian gas pipelines and expanding its sour-gas treating and carbon-capture operations. The deal strengthens Targa’s Permian position and adds $200 million in annual free cash flow.

Allseas will install more than 320 miles of deepwater oil and gas export pipelines for Enbridge in the U.S. Gulf of Mexico, expanding subsea capacity and supporting future production growth.

North Dakota’s Bakken Shale continues to produce more than 1 million barrels per day, but analysts say future growth hinges on technology advances, enhanced oil recovery, and stronger infrastructure investment.

Incorrect internal diameter specifications in insulating gasket kits can cause electrical bridging and galvanic corrosion at pipeline flanges. Saudi Aramco engineers explain how proper bore sizing and torque control are critical to maintaining electrical isolation and long-term integrity.

Pipeline operators are turning to thermal insulative coatings (TICs) to combat corrosion under insulation (CUI) and prevent heat loss. These advanced coatings provide long-term protection, improve energy efficiency, and eliminate moisture-trapping insulation systems prone to corrosion and failure.

A new reliability study from Universidad Nacional de Colombia analyzes how slow crack growth (SCG) and burial design variables—such as soil class, depth of cover, and trench width—affect the long-term performance of HDPE pipelines. Using Monte Carlo simulations and machine learning, researchers identify key factors influencing pipeline failure risk.

Pipe-in-pipe (PiP) systems are moving beyond offshore use and emerging as a safer, more efficient option for transporting LNG, LPG, ammonia and hydrogen onshore. Combining advanced insulation, structural strength and real-time leak detection, modern PiP designs deliver reliability across complex and cryogenic environments.

Emerson’s clamp-on ultrasonic flowmeters measure natural gas volume and composition without process penetrations. By calculating compressibility, molar mass and BTU value in real time, the non-invasive systems provide accurate, low-maintenance solutions for gas quality and flow monitoring across pipeline networks.

McDermott has safely wrapped up subsea pipeline installation and heavy-lift work for Sarawak Shell’s FaS development offshore Malaysia, marking more than one million safe work hours and reinforcing its role in Asia’s offshore infrastructure build-out.

Elevation Midstream has extended the open season for its DJ South Gathering crude pipeline, giving shippers until Jan. 15 to secure capacity on the planned system connecting Adams and Arapahoe Counties to key delivery points in Weld County. The project aims to boost crude gathering reliability across Colorado’s DJ Basin.

CRC Evans has secured a major contract for Saudi Arabia’s Master Gas III Pipeline Phase 3, delivering welding and construction on a 56-inch, 150-km pipeline. The award strengthens the company’s growing presence in the Middle East and highlights its advanced welding technologies and long-term role in the region’s gas infrastructure buildout.

Mozambique has awarded a 30-year concession to state-owned firms ENH, CFM, EDM and HCB to build and operate LNG terminals, storage facilities, and the 865-km Rompco pipeline.

Prospera Energy has completed three pipeline replacement and integrity projects across its Cuthbert and Hearts Hill fields, enabling injector and producer wells to return to service ahead of its 2025–26 winter capital program.

Pipeline & Gas Journal’s new Editor-in-Chief, Tyler Campbell, outlines his vision for deeper technical coverage across pipeline integrity, digital technologies and operational best practices — and invites industry professionals to share their expertise.
