“…26 A pipeline integrity analysis based on the novel computerized techniques local to a pipeline company was developed focusing on the effects of the induction and earth conduction on the structural durability of concerned pipeline system. 27 A numerical analysis of oil slurry transportation through pipeline systems was conducted through utilization of the CFD tools by the application of FLUENT 6.3 software. The obtained results related to the fluid pressure drop were compared with the experimental data and were found to match closely with the experimentally determined results.…”

Pipeline systems serve a crucial role in an effective transport of fluids to the designated location for medium to long span of distances. Owing to its paramount economic significance, pipeline design field have undergone extensive development over the past few years for enhancing the optimization and transport efficiency. This research paper attempts to propose a methodology for flexibility analysis of pipeline systems through employing contemporary computational tools and practices. A methodical procedure is developed, which involves modeling of the selected pipeline system in CAESAR II followed by the insertion of pipe supports and restraints. The specific location and selection of the inserted supports is based on the results derived from the displacement, stress, reaction, and nozzle analysis of the concerned pipeline system. Emphasis is laid on the compliance of the design features to the leading code of pipeline transportation systems for liquid and slurries, ASME B31.4. The discussed procedure and approach can be successfully adjusted for the analysis of various other types of pipeline system configuration. In addition to the provision of systematic flow in analysis, the method also improves efficient time-saving practices in the pipeline stress analysis.

In this paper a generalized fundamental solution using the boundary element method to solve the Helmholtz equation is proposed. It is observed that the commonly used fundamental solution is only valid for good conductors since the capacitive effect of the considered medium is always neglected.By the use of the well-known Lorentz gauge condition a fundamental solution which incorporates the phase as well as the attenuation transmission coefficients is derived by the authors. Next, a model is developed using this proposed fundamental solution for modelling a coating layer of a buried pipeline. Subsequently, a model of a buried coated pipeline in close proximity to a high voltage power line is developed and numerically implemented.Finally, the model is used to simulate two configurations in order the verify the proposed general fundamental solution of the boundary element method for electromagnetic field problems. Hereby, its validity is proven and it is shown that the generalized solution and related model can be used for industrial applications.

“…The work in [19] focused on determining the induced voltage on different parts of pipes laid along ultra-high voltage power lines. An analysis of the effects resulting from the proximity of high-voltage electrical networks and pipelines is presented in [20]. The results of a study on the effect of the electromagnetic interference of 750 kV AC power lines on several underground pipelines are presented in [21].…”

Modeling the Effects of Electromagnetic Interference from Multi-Wire Traction Networks on Pipelines

The 25 kV traction network creates highly intensive electromagnetic fields. These fields affect the long conductive structures located near railway lines and can induce voltage, posing a danger for maintenance personnel. Typical examples of such structures are pipelines, which are used to transport liquid and gaseous products. In addition to compromising electrical safety, the induced voltage can result in dangerous densities of corrosion currents in pipe insulation defects. Therefore, the determination of the induced voltage and current in the pipes is undoubtedly relevant. An analysis of existing literature on the electromagnetic compatibility of traction networks and pipelines indicates that important aspects regarding the effects of traction networks and high-voltage power lines on extended conductive structures have been addressed. However, these works do not present a unified method to determine the induced voltage on parts of the structures and the current flowing through the pipeline. Such a method could be based on a technology that models the operation of electric power systems in phase coordinates. This paper presents the development of a method and the results of the studies aimed at modeling the voltage induced by complex traction networks. The developed digital models make it possible to adequately determine the induced voltage created by multi-wire traction networks and the current flowing through the pipes. Using these models, one can make an informed decision regarding the appropriate measure to ensure the safety of personnel working on these structures, as well as the development of corrosion prevention methods and measures.
