oil and gas transmission pipelines are critical items of infrastructure in providing energy sources to regions and countries. steel pipes are commonly used which can be subject to both internal and external corrosion. this paper presents an advanced nondestructive inspection technique for detection of oil-gas pipeline corrosion defect. the pulsed eddy current (pec) method has been successfully ...

Pipelines play a critical role in matching the supply and demand of natural gas. The pricing of their capacity is an important problem in practice, both for pipeline companies and shippers, the users of this capacity, including natural gas merchants, producers, and local distribution companies. This paper conducts a normative analysis of how pipeline capacity should be priced by each of these p...

Because of the continuous growth of electric energy consumption and the trend with electric lines of high voltages energy transport and metal pipelines which compose the transport of the fluids and liquid or gas hydrocarbons in the same corridor, the parallelism and the proximity of the power lines and the metallic pipelines become increasingly common. Consequently, it was an increasing concern...

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 ...

recent years have brought a great deal of expansion to the economic systems of developing countries. although they serve as vital link of economic activities, the transportation network of these countries have not grown proportionally. since transportation investments is a a substantial portion of the national budget, a good knowledge of each mode's various characteristics is essential, wh...

Peter Bauer, ABB Automation, USA, and Billy Mann, West African Gas Pipeline Company Ltd, discuss the importance of SCADA system integrity to the West African gas pipeline. Gas operators are finding the need for more and more advanced technology to keep up with their data collection and processing requirements. This includes data from smart field devices, increasingly sophisticated control syste...

Arguably, the natural gas transmission pipeline infrastructure in Iran represents one of the largest and most complex mechanical systems in the world. The optimization of large gas trunk lines known as IGAT results in reduced fuel consumption or higher capability and improves pipeline operation. In the current study, a single-objective optimization was conducted for Khormoj compressor station o...
