In 1996, the Federal Energy Regulatory Commission (FERC) established criteria it uses when evaluating proposals for marketbased rates by natural gas pipelines. Since that time, a number of significant developments have occurred, both in markets for natural gas transportation and in economic tools for marketpower assessment. This article will review the current approach for measuring interstate ...
Recently, with large-scale use of natural gas and massive constructions of gas pipelines, more and more public concern is focused on pipeline leakage. The leakage caused by holes on gas pipelines generates economic losses to gas companies and causes risks to the environment and sometimes accidents. In order to detect and locate pipeline rupture immediately, the leakage detection method plays a ...
The occurrence of the severe slugging phenomenon in multiphase pipelines can cause serious and troublesome operational problems within the receiving process facilities. This paper describes: the pipeline operability studies on the Dunbar to Alwyn multiphase pipeline regarding riser-induced severe slugging; the control scheme selected to prevent this phenomenon; and the subsequent operating expe...
Here, we uncover the load and fault-tolerant backbones of the trans-European gas pipeline network. Combining topological data with information on intercountry flows, we estimate the global load of the network and its tolerance to failures. To do this, we apply two complementary methods generalized from the betweenness centrality and the maximum flow. We find that the gas pipeline network has gr...
Many different wireless sensor nodes for gas pipeline leak detection and location has been proposed but still there are challenges particularly on environmental issues and signal accuracy. This paper discusses theories and environmental constraints for wireless sensor nodes, a case study of Dar es Salaam Tanzania and finally presents a design and simulation results of the proposed wireless sens...
Nowadays, centrifugal compressors are commonly used in the oil and gas industry, particularly in the energy transmission facilities just like a gas pipeline stations. Therefore, these machines with different operational circumstances and thermodynamic characteristics are to be exploited according to the operational necessities. Generally, the most important operational parameters of a gas pipel...

Nowadays, the stress analysis mostly aimed at general buried pipelines. And few of the gas pipelines in tunnel (especially under the seismic action) were analyzed. Therefore, it is necessary to analyze the stress distribution of gas pipeline under seismic action in tunnel. In this paper, CEASAR II software was used to establish the stress model of China-Myanmar XX tunnel pipeline under seismic ...
