Abstract The study for the natural gas pipeline system (NGPS), particularly about resilience evaluation, is still in its early stages. Resilience a hot point most important aspects of security assessment. An integrated simulation model presented assessing supply NGPS, incorporating topological and operational circumstances. This takes different forms disruptions into consideration. Analysis don...

Abstract There was a west-east gas transmission pipeline nearby the Yanmenguan DC grounding electrode. In order to assess electromagnetic interference of electrode on pipeline, an simulation model established. The earth potential analyzed. effects insulation layers and joints were investigated. It can provide theorical support for pratical operation pipelines.

offshore pipelines used for oil and gas transportation are often buried to avoid damage from fishing activities and to provide thermal insulation. thermal expansion and contraction of the pipeline during operation can lead to lateral or upheaval buckling. a safe buried pipeline design must take into account a reliable evaluation of soil uplift resistance and pipe embedment depth. while the cost...

in this study a pseudo comprehensive carbon footprint model for fossil fuel power plants is presented. parameters which their effects are considered in this study include: plant type, fuel type, fuel transmission type, internal consumption of the plant, degradation, site ambient condition, transmission and distribution losses. investigating internal consumption, degradation and site ambient con...

Recently, the API X100 steel has emerged as an important pipeline material for transportation of crude oil and natural gas. At the same time, the presence of significant amounts of hydrogen sulfide (H2S) in natural gas and crude oil cause pipeline materials to corrode, which affects their integrity. In this study, the effect of H2S concentration on the corrosion behavior of API X100 in 3.5% NaC...

Pipeline systems are vital infrastructure to national economy, and are widely used for transporting liquid and gas matter, such as oil, natural gas, water and chemic materials. However, effective and efficient management of pipeline systems are challenging, due to its mere lengths and the diverse deployment environments. Wireless sensor network (WSN) consists of a large number of sensors, which...
