Landslides are a risk to buried gas pipeline infrastructure, but these risks particularly difficult assess given the complex nature of landslide movements. This paper presents portion research conducted at University Manitoba where pipelines within active areas were monitored over 4 year period. Two locations examined in western Assiniboine River Valley shallow natural runs parallel valley slop...

Pipeline transportation of multiphase products, such as gas and oil mixtures, exhibits complex varying flow regimes: a result, analytical approaches or conventional methods cannot accurately describe the composition propagation characteristics fluid mix inside system itself. We address an issue by presenting methodology, driven data applied to real case history, where basic pressure transients ...

A novel electromagnetic-based method is presented for monitoring elemental sulfur deposition within a natural gas-carrying pipeline. The deposited behaves as superstrate layer above sensing microstrip patch antenna that optimally placed on the inner wall of gas Increasing thickness by alters resonance behavior, which can be monitored externally using vector network analyzer. effect uneven or bu...

Worldwide consumption in oil and natural gas is expected to lead all other energy sources in the next 20 years. The oil & gas pipeline network will constantly expand placing greater demand on operators to ensure any integrity threats to these pipeline systems are accurately and reliably identified. What are the main integrity threats to pipelines? There are many such as third-party damage, exte...

the purpose of this study is environmental risk assessment of pipelines in case study conducted in the 9th national gas pipeline in lorestan province (iran). the study employed the indexing method for investigating the risk through the muhlbauer method. geographic information system is also used to develop the maps corresponding to the environmental risks and to map the relative risk scores and...

This paper simulates transient compressible adiabatic gas flows in a long pipeline following a catastrophic failure using an implicit high order finite difference scheme as a discretisation technique for convective terms. A rupture is assumed to be occurred accidentally at a distance from the feeding point of a pipeline where the pipeline being divided into two distinct sections, high and low p...

Leak detection systems are a fundamental part of the management system associated with any long distance pipeline. Such systems are necessary to avoid or reduce environmental and economical losses in case a leak develops in the pipeline. There are several solutions, with different efficiency and cost-effectiveness, for this problem. One of the most appealing is the use of software based leak de...
