Ductile fracture propagation control in modern high strength steel pipeline for transportation of high pressure natural gas with H2 and CO2 contents: arrest requirements evaluation by numerical tool and full-scale testing verification
Ductile fracture propagation control in modern high strength steel pipeline for transportation of high pressure natural gas with H2 and CO2 contents: arrest requirements evaluation by numerical tool and full-scale testing verification
One of the most severe accidents which could occur in a gas transmission pipeline involves the linepipe wall failure and subsequent fracture initiation, which may evolve in a long running fracture propagation if the material toughness properties are not adequate. The most acknowledged approach for ductile fracture propagation assessment is the...

Application of Pipeline QRA Methodologies to Hydrogen Pipelines in Support of the Transition to a Decarbonised Future

Application of Pipeline QRA Methodologies to Hydrogen Pipelines in Support of the Transition to a Decarbonised Future
Application of Pipeline QRA Methodologies to Hydrogen Pipelines in Support of the Transition to a Decarbonised Future
Hydrogen is expected to play a key role in the decarbonised future of energy. For hydrogen distribution, pipelines are seen the main method for mass transport of hydrogen gas. To support the evaluation of risk related to hydrogen pipelines, a revised QRA methodology is presented based on currently available and industry accepted guidance related to...

Opportunities to Access the Benefits of High-Frequency Welded (HFW) Pipes for a Wider Scope of Oil and Gas Industry Applications

Opportunities to Access the Benefits of High-Frequency Welded (HFW) Pipes for a Wider Scope of Oil and Gas Industry Applications
Opportunities to Access the Benefits of High-Frequency Welded (HFW) Pipes for a Wider Scope of Oil and Gas Industry Applications
In recent years, many papers have been published describing the advantages and disadvantages of the high-frequency welded (HFW) and seamless (SMLS) carbon and low-alloy steel (LAS) pipe manufacturing processes for the oil and gas industry. However, there are few published papers that compare these different manufacturing processes in a way that...

Versatile technology for Leak Detection, Third Party Interference and Integrity Assessment applications: Vibroacoustics

Versatile technology for Leak Detection, Third Party Interference and Integrity Assessment applications: Vibroacoustics
Versatile technology for Leak Detection, Third Party Interference and Integrity Assessment applications: Vibroacoustics
Leak detection, TPI (Third Party Interference) and asset integrity are crucial topics in pipeline monitoring, although they often require costly procedures and systems. In order to support the pipeline integrity management, Eni S.p.A, in collaboration with Solares JV, developed the e-vpms® (Eni Vibro-acoustic Pipeline Monitoring System). This...

Real-Time Networks: Gas Data, Demand and Network Modelling
The gas industry in Great Britain has experienced fundamental change over the last 20 years and is continuing to change rapidly. There has been a reduction in indigenous supply, with an acceleration in the connection of new unconventional sources through biomethane supplies and the potential for hydrogen blending in the future. These changes are...

Application of Distributed Fiber Optic Sensing for Pipeline Integrity and Security

Application of Distributed Fiber Optic Sensing for Pipeline Integrity and Security
Application of Distributed Fiber Optic Sensing for Pipeline Integrity and Security
Even the smallest leak can have devastating consequences. The protection and monitoring of pipeline infrastructure is critical to the continued performance of the pipeline. Loss of integrity, through accidents or malicious activity, can have a significant impact on the environment, on reputations and on finances. Distributed Fiber Optic Sensing is...

BIL enquiry portal contributes German pipeline safety
A highly developed society naturally believes that it has elimi nated its risks. Insurances, traffic information, social systems, legislation, and finally all kinds of regulations weigh us down in a cor set of security of our own actions, which can hardly lead to negative consequences. Infrastructure and pipeline security is a valuable asset, on...

Stress Corrosion Cracking (SCC) Susceptibility Screening Enhancement

Stress Corrosion Cracking (SCC) Susceptibility Screening Enhancement
Stress Corrosion Cracking (SCC) Susceptibility Screening Enhancement
Stress Corrosion Cracking (SCC) is a wel l- known threat to the integrity of oil and gas pipelines. SCC is a damage mechanism that typically results in axial cracks on pipelines due to simultaneous action of tensile stress, potent environment (soil, coating, electrolyte etc.), and the pipeline material (poor microstructure). Small cracks are in...

Novel Classification Of Leak Detection And Third-Party Intrusion Enabling Best-In-Class False Alarm Rate

Novel Classification Of Leak Detection And Third-Party Intrusion Enabling Best-In-Class False Alarm Rate
Novel Classification Of Leak Detection And Third-Party Intrusion Enabling Best-In-Class False Alarm Rate
We demonstrate PrismaFlowTM’s best in class events det ection and classification capabilities accompanied by negligible False Alarm Rate (FAR). A 35 km long pre-depl oyed optical cable inside a conduit was used as the sensor. Originally deployed for communication purposes, the optical cable, running along the infrastructure, was placed along highly...

Detecting Illegal Tappings – A Research Case Study
Illegal hot tapping and product theft is a problem for pipeline operators all over the world. As criminals use a wide range of different instal lations and are in many cases able to adopt t heir ways of siphoning and stealing to the pipeline conditions a research project had been started by GLD, together with another service company and two...

Leak & Theft Detection Strategies: Integrating Established And Innovative Technologies
Pipeline leak and theft detection can be done through various technologies. There is no si ngle best method as each pipeline is different and ideally, it is best to integrate several different methods within any detection system. Two of the most popular and established methods are flow balance and negative pressure wave, however, both have their...
