... Abstract Analysing the leak detection sensitivity for a particular system, or predicting how operational transients influence it, are common challenges for leak detection professionals. An empirical approach can be followed: modeling the pipeline system, including all the inaccuracies due...

... Abstract In the recent decades, new leak detection technologies for hydrocarbon pipelines are emerging constantly, and conventional technologies are evolving to achieve better performance. It gives pipeline operators a good chance to detect leaks in the early phase and protect the environment...

... ABSTRACT Noise is prevalent in all pipeline instrumentation and measurement system data and has been shown to affect Computational Pipeline Modeling (CPM) based leak detection (LD) systems in practice. Noise present in data can be random or repetitive, occurring continuous or in isolated...

... ABSTRACT: Leak detection systems come in many "flavors", each with distinct advantages, disadvantages and sometimes unique features and capabilities. Needless to say, performance and cost vary greatly as well. It can be a daunting task to decide which technology to invest in for a specific...

... also matters. Leak detection systems that rely on prompt identification of the rarefaction wavefront at critical locations may siginificantly lower risk posed by pipeline rupture. Local leak detection is often tied to Excess Flow Valves that shut automatically when the flow exceeds a threshold value...
