... surveillance should be performed. The methods presented here estimate the relative order of magnitude of measurement error/leak and have been validated on double blind simulated data. measurement uncertainty leak detection Proceedings of the 2024 15th International Pipeline Conference IPC2024...

... of conservatism. Consequently, there have been positive impacts on cost optimization associated with pipeline risk management, both in risk analysis studies and in mitigating potential consequences through improved emergency response resources. oil spill leak detection environment risk analysis loss...

... Abstract Slurry pipelines can be used to move ore or waste material across large distances. The nature of slurry means that conventional mass-flow and statistical based leak detection systems are poorly suited to leak detection. External Leak Detection Systems (LDS) based on Distributed Fiber...

... Abstract Most pipeline control systems use some sort of autonomous leak detection system as a safety feature. Among the pipeline leak detection techniques, state observers stand out as the most sophisticated and promising technique. But its use has been inhibited as the dynamic models employed...

... completed a comprehensive research project to help operators assess the performance of various external leak detection technologies when identifying the presence of liquid hydrocarbon products on the surface of water in a controlled lab environment. Some of these results are presented in this paper...

... 07 04 2011 This paper describes a new approach of data source fusion based on process fusion entropy for leak detecting of product pipelines. Data sources are either single-channeled or multi-channeled: single-channeled data sources can be structured or semi-structured process steady...

... is analyzed and velocity of NPW was revised. By means of Newton-Cotes integration method location formula is modified. The real experimental results show that the improved located formula made location accuracy from 2.5% to 1.0%. Leak detection ICA Noise elimination Axial temperature drop NPW...

... the role of the dynamic simulator in the leak detection system; Sections 2, 3 and 4 present the three units that constitute the algorithm respectively: a network calibration, a monitoring system, and a leak location and quantification routine. Section 5 illustrates the algorithm performance...

... 10 12 2008 This paper describes field trials for two different technologies (built in two commercial products) for leak detection, location and quantification systems (LDS). Modified Compensated Volumetric Balance was tested against SPRT Statistical Analysis, and the obtained results...

... 10 12 2008 This paper describes experiences with an improved equation of state (EOS) for ethylene for an existing real time pipeline model. The main scope of the model is leak detection, batch, contaminant and pig tracking. Altogether the pipeline model includes transportation...

... Transient Hydraulics Slack Flow Pressure Regulation Leak Detection There are many existing liquid transmission pipelines that have significant changes in elevation along their route, making them susceptible to operating at “slack flow” conditions. Slack flow occurs in a pipeline when...

... rarefaction-pressure wave leak detection localization applied research In China, the rarefaction-pressure wave techniques are widely used to diagnose the leakage fault for liquid pipelines. Many leaking propagating assumptions, such as stable single-phased flow hypothesis and none...

.... This paper shall present an automated leak detection system (i. e., without human intervention for shutting pumps down) for a short (approximately 6 kilometres long), 6 inch., liquid ammonia pipeline located at the city of Cubata˜o, state of Sa˜o Paulo, Brazil, within the bounds of a fertiliser producer...

... 07 10 2008 Oil and gas transportation pipelines are the key equipment in petroleum and chemical industry. At present, with the increase of transportation task in oil fields, real-time leak detection system becomes a demand that petroleum companies need to safeguard routines...
