RISK MANAGEMENT IN OIL PIPELINES AND GAS PIPELINES
International Oil Spill Conference Proceedings, 1995ABSTRACT Several methods have been developed by Dutos e Terminais do Centro-Oeste e São Paulo, a subdivision of Petrobrás's Transportation Department, to guarantee the mitigation of identified risks in pipeline installations, using a managerial approach rather than the traditional technical approach.

DESULPHURIZATION OF GAS AND CORROSION CONTROL IN PIPELINES
Proceedings of Middle East Technical Conference and Exhibition, 1981ABSTRACT The need to develop a national source of energy linked with gas contracts specifications, environmental and corrosion problems have brought SNEA to develop its own gas desulphurization process. This had lead to a big sulphur production and a new source of revenues, as well as licence selling.

Leak monitoring system for gas pipelines
IEEE International Conference on Acoustics Speech and Signal Processing, 1993An approach and a solution to the continuous leak monitoring problem in underground gas pipelines are presented. This approach places permanent monitoring units along the pipeline. These units detect acoustic signals in the pipeline and discriminate leak sounds from other man-made or natural nonleak sounds that can occur.

Access to Pipelines in Competitive Gas Markets
Journal of Regulatory Economics, 2003In this paper we provide the normative benchmark characterizing the optimal allocation of resources in a gas network. By duality, we determine the consumer and producer prices, at each node of the network, which decentralize this allocation with competitive actors.

Modeling the dynamics of flow in gas pipelines
IEEE Transactions on Systems, Man, and Cybernetics, 1984The description of nonstationary one-dimensional flow of a nonideal gas in a pipe is treated with the goal of developing a mathematical description of flow and pressure (density) dynamics adequate for creating a simulation model of large pipeline networks, the analysis starts from Newton's equation of motion.

Watching Brief at Sharpness to Lydney Gas Pipeline, Sharpness to Lydney Gas Pipeline
2004This report details the findings of a permanent-presence archaeological watching brief which took place during construction of the c. 3.7km long Transco Sharpness to Lydney Gas Pipeline in Gloucestershire. The pipeline runs north west from an undesignated minor road near Sharpness, beneath the River Severn, to the A48 north east of Lydney.

Transients in Gas-Condensate Natural Gas Pipelines
Journal of Energy Resources Technology, 1998Liquid condensation in natural gas transmission pipelines commonly occurs due to the thermodynamic and hydrodynamic imperatives. Condensation subjects the gas pipeline to two-phase transport. Neither the point along the pipeline at which the condensate is formed nor the quantity formed is known a priori.

Flow Equations for Natural Gas Pipelines
Transactions of the American Society of Civil Engineers, 1958In use of various equations in pipe line design, practice is to apply Pipeline Efficiency factor; three equations most widely used for design are given; use of equations in operation study and capacity testing; difference between flow equation; determining behavior of resistance coefficient.

On the Pricing of Natural Gas Pipeline Capacity
Manufacturing & Service Operations Management, 2010Pipelines play a critical role in matching the supply and demand of natural gas. The pricing of their capacity is an important problem in practice for pipeline companies and the users of this capacity, which include shippers such as natural gas merchants, producers, and local distribution companies.

Management of Pipeline Dents and Mechanical Damage in Gas Pipelines
Volume 2: Integrity Management; Poster Session; Student Paper Competition, 2006This paper describes an approach used by Duke Energy Gas Transmission (DEGT) to manage dents and mechanical damage as part of its overall Integrity Management Plan (IMP). The approach provides guidance in the process for evaluating deformation anomalies that are detected by high resolution magnetic flux leakage (HR-MFL) and multi-channel geometry in ...
