Third party damage is as a significant factor in natural gas pipeline failures. 75% of pipeline failures induced by a third party occur immediately following impact. Current inspection techniques are both labor intensive and expensive to implement and they represent only a point in time status. The objective is for a near real time detection and communication system that utilizes the pipe itself, i.e., a “smart pipe”. The industry is calling for an inexpensive rugged process that transmits the state of the pipe. The INEEL is developing a near real time damage detection and location system that utilizes resistive traces applied to the wall of the pipe, which detects damage by measuring the strain state of the pipeline. This data will also allow for efficient repairs and emergency response. The technique employed is a network of thermally sprayed resistive traces deposited on either the interior or exterior wall of the pipeline. The ability of a thermally sprayed resistive trace to detect damage is due to the unique manner in which a porous metal changes resistivity when placed under strain.

The gas industry has an excellent safety record in operating high pressure transmission pipelines. Nevertheless, it is important that pipeline operators have an understanding of the possible consequences of an accidental gas release, which may ignite, in order to help manage the risks involved. This paper describes two full scale experiments, conducted as part of a research programme into the consequences of pipeline failures, undertaken by an international collaboration of gas companies. The experiments involved the deliberate rupture of a 76km length of 914mm diameter natural gas pipeline operating at a pressure of 60 bar, with the released gas ignited immediately following the failure. Instrumentation was deployed to take detailed measurements, which included the weather conditions, the gas outflow, the size and shape of the resulting fire, and the thermal radiation levels. The results provide important data for the validation of mathematical models, used in developing risk assessment methodologies, and in establishing those standards and design codes for gas pipelines that are risk based.

This article discusses why Russia replaced the South Stream project with the TurkStream by changing its route and name, and why Turkey is involved in a project on the North-South line although it plays a vital role in the Trans-Anatolia Natural Gas Pipeline (TANAP) project in the southern gas corridor. The article first examines the Russia-Ukraine natural gas crisis. It then moves to analyze the reasons behind Russia’s changing of the name and the route of the South Stream project. After exploring Turkey’s involvement in the project, the article concludes by arguing that both countries adopted a win-win approach toward the project that Russia has gained a significant tariff advantage and freedom from the EU third-party-access rule. The article claims that although both Russia and Turkey have different perspectives on some issues in international politics, they can develop their cooperation with a win-win approach in the TurkStream project.

Ready Access

Broadly stated, the objective of the National Third Party Access Code for Natural Gas Pipeline Systems is to promote competition in natural gas markets. For the National Access Code to achieve this objective in a meaningful way, it must allow prospective gas suppliers to gain ready access to pipeline systems.This paper considers two particular aspects of the National Access Code which may cause difficulties for new gas suppliers who wish to compete with incumbent gas aggregators. The first issue relates to the ease with which a new gas supplier can identify what spare capacity is available in a pipeline. The second issue is what type of capacity a new gas supplier can hope to obtain.

Subject The decision to restart the TurkStream natural gas pipeline from Russia to Turkey. Significance The agreement on August 9 between Russian and Turkish Presidents Vladimir Putin and Recep Tayyip Erdogan to resume the TurkStream project relaunches their partnership in the energy sector. This had been frozen as a result of Turkey's shooting down of Russian Su-24 jet last November. Impacts Turkey could start importing up to 15.75 bcm additional natural gas under the Black Sea by 2019. Such a reduced amount compared with the original plan would seem to allow room in the Turkish gas market for rival suppliers. TurkStream could be extended into the EU only if the European Commission and Gazprom compromise on third-party access to the pipeline.

Abstract Transportation of natural gas from gathering station to consumption centers is done through complex gas pipeline network system. The huge cost involved in transporting natural gas has made pipeline optimization of increased interest in natural gas pipeline industries. In the present work a lesser known application of Ant Colony in pipeline optimization, has been implemented in a real gas pipeline network. The objective chosen is to minimize the fuel consumption in a gas pipeline network consisting of seven compressors. Pressures at forty-five nodes are chosen as the decision variables. Results of Ant Colony Optimization (ACO) have been compared with those of GAMS that utilizes ‘Generalized gradient principles’ for optimization. Our results utilizing ACO show significant improvement in fuel consumption reductions. Similar procedures can be adopted by researchers and pipeline managers to help pipeline operators in fixing up the pressures at different nodes so as the fuel consumption in compressors gets minimized.

The implementation of fault detection techniques in industrial systems for process monitoring has proven to be a useful tool to process operators supervising the plant’s operation conditions. As plants become more instrumented, more data is available for fault detection applications, if they are capable of demonstrate anticipation and low false alarm rates. A regional Natural Gas transportation system deals with these types of drawbacks. While the improvements are carried out, some effort should be done in order to improve the safety in operations. In this paper a data-driven technique was used to detect fault conditions along the pipeline, sectioning it in five partitions to increase the detection sensibility. To overcome the lack of quality in data, simulation software intended to gas controllers training and pipeline operation was used to simulate leaks scenarios. Some historic data with high quality is also used to create normal operation condition models by means of Principal Component Analysis. All simulated faults were detected in a reduced time gap and recent events related to third-party actions showed the tool proficiency to detecting faults in real time. In addition, it considers a fault normalized index per section indicating the fault persistence and aggressiveness in a single plot.
