This paper presents an advanced pipeline monitoring system designed to detect and locate leaks and third-party interference (TPI) incidents across a wide variety of pipeline geometries and transported fluids. The system leverages Vibroacoustic Technology (VT), offering real-time asset monitoring and integrity assurance. Over the years, VT has been...

This study presents the development and qualification of sour‑grade API X60 steel for 16”–24” LSAW pipes for the Dos Bocas Refinery project. Production employed KR desulfurization, vacuum degassing, and strict casting controls to minimize inclusions and segregation. Two chemistries were evaluated: DOE‑1 (w/o Ni/Cu) and DOE‑2 (with Ni/Cu)...

In 2023, an oil and gas operator in the East China Sea needed to upgrade its 28 inch gas export pipeline (GEP), including modifications to the pig launcher and associated pipework on one offshore production platform. The 345-kilometer GEP transports natural gas from the offshore platforms to the onshore processing terminal and is one of the...

There is a wide public acknowledgement that the path to Net-Zero requires the deployment of Carbon Capture, Utilization, and Storage (CCUS) at an industrial scale. Realizing a CCUS value chain requires transporting dense CO2 by pipeline over long distances to storage or users. Currently, the CO2 pipeline landscape consists of just over 7,000...

As oil and gas operations transition into deeper waters and more technically demanding basins, the integrity of subsea infrastructure has never been more critical. This article examines the role of hydrostatic testing and fluid preservation as a proactive asset-protection strategy. While hydrotesting is a standard verification of mechanical...

In the technical area of the energy industry, the business processes have been adapted to the issues of planning, construction and operation. The product development of information technology for Asset Management has also been supported by technologies to support construction activities and maintenance using Geographic Information Systems (GIS). In...

JULY 11, 1933 – JUNE 11, 2025 Robert “Bob” Eiber was called home on June 11, 2025, at the age of 91 in Columbus, Ohio. Born July 11, 1933, in Cleveland to Harry and Grace Eiber, Bob lived a life defined by kindness, humility, and quiet accomplishment. He will be deeply missed as a devoted husband, father, grandfather, and friend. Known for his...

Pipeline operators are managing more complexity using infrastructure that was designed for simpler operating conditions. Decarbonization, new products and higher expectations for safety and commercial accuracy are changing how pipelines are used. In many cases, operators cannot add instrumentation or redesign assets, but smart software and advanced...

The pipeline industry is at a turning point. In Europe, the course is being set for a future hydrogen backbone, existing networks are being prepared for decarbonization projects, and CO₂ transport chains are being planned. At the same time, the Asia-Pacific region is developing at a rapid pace, characterized by offshore projects and regionally...

Determining the minimum wall thickness for supercritical CO₂ pipelines requires consideration of multiple factors: internal design pressure, ductile fracture arrest, and dynamic pressure surges. While the design thickness for internal pressure can be readily calculated using ASME B31.4, the impacts of ductile fracture and surge pressures (similar...

Hydrocarbon energy remains essential to the global economy, with pipelines being the most efficient way to transport these resources. However, rising demand, aging infrastructure, and shifting operational conditions increase the risk of failures that can disrupt supply chains. To ensure reliability, proactive risk management is crucial...

Cathodic Protection (CP) systems are essential to mitigate corrosion in buried pipelines; however, naturally occurring telluric currents induced by geomagnetic disturbances can significantly impact CP performance. This study presents an analysis of PSP fluctuations along an approximately 200 km section of Pipeline A traversing Gujarat and Madhya...

When designing pipelines for transporting CO2 in dense-phase, the complex decom-pression behavior places high demands on the material toughness. However, due to the small number of full-scale burst test results in CO2 available to date that addition-ally encompass only a narrow envelope of geometries and material properties, it is difficult to...

The progressing energy transition and a fast buildup of the hydrogen pipeline backbone will play a major role in achieving net zero targets. The conversion of existing pipelines for the transport of hydrogen will play a key role in achieving the targets, which introduces new challenges for pipeline owners and operators. Pipeline repurposing...
