laska has accepted two Stranded Gas Applications that will allow North Slope producers to enter into negotiations on terms to construct natural gas pipelines to the Lower 48. The applications, which suggest that the future for major pipelines to bring natural gas to the U.S. remains bright, also indicate the rising competitive interest in building such a pipeline. Alaska Gov. Frank Murkowski an...

According to statistic data of China in recent years, gas explosion accounted for above 70% in all coal mine accidents. Frequent gas explosion accidents have caused great losses of lives and property. Therefore gas detection and monitoring system is needed to serve as a safety device in coal production. In this paper, an intelligent gas detecting system is designed. This detection instrument ad...

The evolution of a gas shell, swept by the supernova remnant of a massive first generation star, is studied with H2 and HD chemistry taken into account and with use of a semi-analytical approximation to the dynamics. When a first-generation star, formed in a parent pregalactic cloud, explodes as a supernova with explosion energy in the range of 10erg− 10 erg at redshifts of z = 10− 50, H2 and H...

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...

My dissertation concentrates on several aspects of supply chain management and economic valuation of real options in the natural gas and liquefied natural gas (LNG) industry, including gas pipeline transportation, ocean LNG shipping logistics, and downstream storage. Chapter 1 briefly introduces the natural gas and LNG industries, and the topics studied in this thesis. Chapter 2 studies how to ...
