Additional Functionalities Of Model Based Leak Detection Systems To Improve Pipeline Safety And Efficiency
Additional Functionalities Of Model Based Leak Detection Systems To Improve Pipeline Safety And Efficiency
The main purpose of a l eak detection system is of course the reliable and sensitive de tection and localization of leaks in a pipeline. Nevertheless certain systems such as those that are based on a pipeline model (e.g. E-RTTM based system, i.e. extended real-time transient model) deliver additional information of the pipeline operation and...

Real-Time Gauge Positioning And Inspection During Pigging Operations In Gas Pipelines

Real-Time Gauge Positioning And Inspection During Pigging Operations In Gas Pipelines
Real-Time Gauge Positioning And Inspection During Pigging Operations In Gas Pipelines
This paper presents a procedure for continuous real-time positioning and tracking of a Pipeline Inspection Gauge(PIG) travelling within a pipeline, by exploiting the pressure transients it generates during the displacement. In fact, the PIG produces recognizable sounds when crossing the welding dents and while sl iding against the pipe walls. This...

the Covid 19 pandemic has overwhelmed us all like a tsunami - unwanted, unanticipated and therefore completely surprising. It has plunged the global economy from a high into a deep crisis in a very short time. Nearly all areas of social and economic life have been affected and have to switch to standby or abort in the shortest possible time - or...

An Exploratory Data Analysis Of Pipeline Coating Degradation

An Exploratory Data Analysis Of Pipeline Coating Degradation
An Exploratory Data Analysis Of Pipeline Coating Degradation
Pipeline coatings can be constructed from a multitude of materials, all of which aim to provide a physical barrier between a pipeline and the external environment. Naturally, understanding the degradation characteristics of these different coating materials is critical, as with the onset of coating degradation comes metal degradation, i.e...

Editorial: An interesting pipeline year lies ahead

Editorial 6-2019
Editorial 6-2019
The pipeline community do not usually think in terms of individual years - the projects are usually too long-term for that. But some individual years are special. 2020, for example, will be interesting in various respects. On the one hand, legal disputes about specific projects are moving into the next round. Coastal GasLink, for example, continues...

Are we filling the pipeline with a capable “Next Generation Workforce?”
“For the first time in the history of mankind, there are four generations in the workforce. There are 35 million Traditionalists (Silent Gen) and 84 million Baby Boomers, the largest number of workers, which began to retire in 2010-11. There are 68 million Generation Xers and 79 million Generation Yers (Millennials as they are better known). There...
