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...

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...

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...

Submarine pipelines are appropriate method for transmission of oil and gas from sea bed. Free spans may occur due to the natural uneven seabed or by under-scouring. Vortex Induced Vibration (VIV) can happen in such free spans at high Reynolds number. Resonance occurs if the frequency of vortex shedding is close to the pipeline’s natural frequency leading to its fatigue that can break the pipeli...

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...

Title of dissertation: A STOCHASTIC EQUILIBRIUM MODEL FOR THE NORTH AMERICAN NATURAL GAS MARKET Jifang Zhuang, Doctor of Philosophy, 2005 Dissertation directed by: Professor Steven A.

This paper presents a game-theoretic analysis of multimarket competition with capacity investments, applied to international gas markets. It identifies a strategic advantage of «focused» pipeline gas producers (e.g., Gazprom) over «diversified» multimarket exporters of liquefied natural gas (e.g., Qatar). Based on this, the paper examines the spillover impacts of the Fukushima nuclear accident ...
