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...

In this paper, we use the Global Gas Model to analyze the perspectives and infrastructure needs of the European natural gas market until 2050. Three pathways of natural gas consumption in a future low-carbon energy system in Europe are envisaged: i) a decreasing natural gas consumption, along the results of the PRIMES model for the EMF decarbonization scenarios; ii) a moderate increase of natur...

The paper shows a comparison between two intervention methods for interconnecting gas transmission pipelines within natural system. One implies shutdown of pipelines, while the other one in-service pipelines. Each method is described in detail along with main technological issues, as well related advantages and disadvantages. procedures imply special working techniques such welding or hot tappi...

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...

An Ant Colony Optimization (ACO) algorithm is proposed for optimal tree-structured natural gas distribution network. Design of pipelines, facilities, and equipment systems are necessary tasks to configure an optimal natural gas network. A mixed integer programming model is formulated to minimize the total cost in the network. The aim is to optimize pipe diameter sizes so that the location-alloc...

Introduction: The safety of the Unites States’ natural gas supply is of prime importance since 30% of the energy produced in the country is derived from it. Natural gas is supplied through a million miles of vast pipeline network [1]. Pipeline companies have an impressive safety record due to the proactive role of standards and inspection of pipelines. Since the pipelines are getting old, there...

Regulatory authorities in many countries are moving away from prescriptive approaches for keeping natural gas pipelines safe. As an alternative, risk management based on a quantitative assessment is being considered to improve the level of safety. This paper focuses on the development of a simplified method for the quantitative risk assessment for natural gas pipelines and introduces parameters...

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...
