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...

With the growth of electricity generation from gas energy gas pipeline reliability can substantially impact the electric generation. A physical disruption to pipeline or to a compressor station can interrupt the flow of gas or reduce the pressure and lead to loss of multiple gas-fired electric generators, which could dramatically reduce the supplied power and threaten the power system security....

With the rapid development of natural gas pipeline, the safety of natural gas pipeline is paid more and more attention to. This paper presents a new safety assessment model based on fault tree and fuzzy neural network. Firstly, in the light of fault tree theory, fault tree analytical figure is established for buried natural gas pipeline system and the index system is established about buried na...

Thanks to recent progress in satellite-based remote sensing technologies and object oriented image analysis, as well as to the availability of new very high-resolution sensors, it is now possible to design gas pipeline monitoring systems, as has been demonstrated by the co-funded European “PRESENSE Pipeline REmote SENsing for Safety and the Environment” project. In parallel, the European Space ...

When a natural gas pipeline ruptures, the adjacent upstream and downstream automatic control valves (ACV) should close quickly to prevent leakage or explosion. The differential pressure set point (DPS) at each valve location is the main criteria for value setting in ACV actions. If the DPS is not properly adjusted, the ACV may mistakenly close or it may not take any actions at a proper ti...

Detection of Metal Defects on Gas Distribution Pipeline by Remote Field Eddy Current (RFEC) Using Finite-Element Analysis — It is necessary to find out whether there are metal defects on underground gas distribution pipelines without excavation in order to establish safety strategies for replacement or maintenance. The metal defects are classified into general corrosion, stress corrosion cracki...

There must be few other situations where there are eager purchasers of natural gas (India and Pakistan), willing suppliers of natural gas (Turkmenistan, Iran, Qatar and Oman), and yet, no pipeline. The distances involved are modest, and techno-economic viability appears straightforward. This paper examines in detail the policy, technology, and economics of an overland pipeline supplying natural...

During the period of Anatolian Seljuks, a great importance was given to the urban development as the economic, political or military centers with a synthesis of Islamic, Turkish, Byzantine and Persian cultures. Special care was taken of the introduction of public services, especially the health services that have never been neglected. Seljuks have considered medicine of utmost importance and ha...

This special report looks at the use of natural gas pipeline compressor stations on the interstate natural gas pipeline network that serves the lower 48 States. It examines the compression facilities added over the past 10 years and how the expansions have supported pipeline capacity growth intended to meet the increasing demand for natural gas. Questions or comments on the contents of this art...
