Real-time models and associated applications have been widely used to support the safe and effi cient operation of pipelines from within the confi nes of the pipeline operations environment. Commercial systems have also been independently implemented to manage the business relationships between gas suppliers, shippers, transporters, and end users; however, the direct interchange of information ...

Article history: Received: 27.08.2014. Received in revised form: 08.12.2014. Accepted: 11.12.2014. Pipelines are of major importance for transport of natural gas, but a lot of the current in-service pipelines are in wear-out phase. Safe and reliable operations of these pipelines are related to economic development and social stability. It is of great importance and practical significance to stu...

We propose a merchant-regulatory framework to promote investment in the European natural gas network infrastructure based on a price cap over two-part tariffs. As suggested by Vogelsang (2001) and Hogan et al. (2010), a profit maximizing network operator facing this regulatory constraint will intertemporally rebalance the variable and fixed part of its two-part tariff so as to expand the conges...

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...

Adhesion (cohesion) and agglomeration properties of gas hydrate particles have been a key to hydrate management in flow assurance in natural gas pipelines. Despite its importance, the relevant data in the area, such as the surface energy and the interfacial energy of gas hydrates with gas and/or water, are scarce; presumably due to the experimental difficulties involved in the measurements. Her...

This paper provides a description of the different databases and various influencing factors in the development of a tool to estimate the failure rate of cross-country pipelines. The databases available cover a number of different materials transported: crude oil and liquid products, and natural gas. The various databases give excellent base data to estimate the likelihood of failures of cross-...

Corrosion has been identified as the major problem to the pipeline industry. It single-handedly contributes to over 50% failure of global pipeline system and also cost the industry trillions of dollars annually on prevention and correction. However, as knowledge in corrosion science and engineering advances, the basic knowledge decreases. This work is prepared to study natural gas pipeline corr...

Liquefied natural gas (LNG) terminals, one of the lifeline facilities, need to be protected by a proper seismic design against extreme earthquakes. An LNG terminal consists of a series of process facilities that are connected by pipelines of various sizes. Boil-off gas (BOG) compressor is one of the critical process facilities whose failure will cause the functional failure of the LNG terminal....
