Abstract: The paper considers typical examples of depressurization of coils of long-operated sections of pipelines. An example of an incident was considered when, during the construction of a pipeline, crowns of excavator teeth left impact on the coil. Despite such a construction and installation defect, the coil was operated for almost 40 years. There were defined conditions for fatigue fractures by means of experiments and with the use of twodimensional calculated finite element model of 6016 PLANE 2 elements, designed to analyze stress distribution in regions with significant gradients. The features of the crack process development were investigated in the case of formation of an extended cavity in the zone of the pipe welded butts displacement and with a use of a reinforcing cover as the coil repair element.

Keywords: construction defects, repair defects, metallurgic defects, pipeline destruction.

Abstract: The paper shows the analysis of modern approaches to performance of repeated hydraulic tests to ensure the integrity of operated pipelines with growing fissure-like defects and corrosion induced defects. Advantages and disadvantages of different approaches are listed. A possible damaging effect of hydraulic testing is mentioned to be related to a probable crack initiation of pre-critical defects. The number of such cases is insignificant, as only defects within a limited range may be crackinitiated without degradation at the preset pressure. If the defect size exceeds the range, the defect shall be detected; if its size does not meet the range, the defect shall be damped. The article shows that choosing pressure of hydraulic tests depending on the actual cycle of operating pressure, corrosion rate, characteristics of the pipe metal impact strength and cyclic crack resistance, and the value of operating pressure provides a required interval of repeated tests.

Keywords: hydraulic tests, operating pressure, bearing capacity, cycling crack resistance.

Abstract: The paper presents a mathematical model of ATA degradation kinetics in an oil pipeline developed with taking into account the threshold for the degradation termination and the molecular mass distribution function of macromolecules, as well as the dependence of the rate of degradation on the flow velocity, the geometric parameters of the pipeline, and the physical and chemical parameters of raw hydrocarbons. Model parameters were identified on the basis of experimental data obtained at one of the regimes at a constant concentration of the additive. Predictive estimates on other regimes showed a satisfactory correspondence of the theory to the actual situation, which is the first evidence that the mathematical model is adequate.

Keywords: anti-turbulent additives, degradation, degradation termination threshold, testing, mathematical model.

Abstract: In this paper, we present the results of experimental studies on the effect of cold metal deformation on a change in the initial mechanical properties of metal during manufacture of large diameter longitudinal welded pipes of strength class K56 using various molding schemes. Samples were cut of different areas in the sheet metal and from the corresponding zones of pipes made from this sheet metal for the purpose of evaluating the effect of pipe processing on the mechanical and viscosity and plasticity properties of the metal. Changes in the properties of the metal was assessed on the basis of results of tensile testing of flat full thickness samples and impact testing of samples with a V-notch.

Keywords: sheet metal, pipe billet, molding, pipe processing.

Abstract: The application of horizontal directional drilling (HDD) method is widespread in the world practice for construction of underwater passages of main pipelines. In order to assess its economic and technological feasibility, conditions of construction on more than 100 underwater passages were analyzed. Draft power of drilling rigs while dragging the pipeline are considered in order to determine the maximum possible length of an underwater passage for each size of the pipeline. Based on the results of consideration of technical and economic aspects of the pipeline route construction, there were introduced technical and economic limitations of the HDD method application for the construction of underwater passages of main pipelines.

Keywords: horizontal directional drilling, underwater passage, main pipeline, emergency situation, technical and economic limitations.

Abstract: An impact of the activities of Transneft system organizations (TSO) on the development of the constituent entities of the Russian Federation is considered in the article, and the role of tax transfers in the formation of regional and local budgets is analyzed. It is shown how the volume and structure of tax payments have changed during 20122016, with the factors affecting the amount of tax transfers analyzed. Specific taxation aspects of TSO production activities are considered. A consideration is given on the influence of both the tariff policy pursued by the state in relation to natural monopolies in the sphere of oil and oil products transportation through main pipelines and the state tax policy leading o the redistribution of tax payments. The relationship between the reduction of investment opportunities of natural monopolies and the reduction of revenues to the regional budgets from the income tax are described.

Keywords: Transneft system organization (TSO), tax policy, income tax, consolidated group of taxpayers, property tax, the state tariff policy.

Abstract: The article discusses a monitoring algorithm for processes of oil mixture and an approach to calculation of its quality indicators distribution in flow traffic. The mixture process monitoring algorithm consists of several components: a forecast calculation of the oil quality indicators, an analysis of their change, detected deviations between the forecast calculation and actual data, provided recommendations on avoiding deviations. The forecast calculation is conventionally divided into a longterm and short-term ones. The task of the long-term forecasting of quality indicators is reduced to a solution of the classical transportation problem. The present-day scientific sources do not describe setting a task of short-term forecasting of oil quality indicators, and as a consequence, there are no acceptable ways to solve the problem. The task of short-term forecasting of quality indicators can be reduced to a dynamic transportation task with delays, which, when solved, will increase the accuracy and reduce the difficulty making short-term forecast calculations due them being automated.

Keywords: oil, monitoring, oil mixture, flow traffic generation, quality indicators.

Abstract: This article describes the real-life case of the whole journey that MOL Logistics had to take to achieve a properly functioning pipeline leak detection system in a brownfield environment. Taking into account strengths and weaknesses of the available technologies, the pipeline characteristics and the operational circumstances the expert team decided to apply pressure wave method as the main principle and specified the new system performance expectations. Based on the test results the performance of the new system had met the expectations which at the same time means we have reached the technical limits of this method.

Abstract: However, starting in 2011, a new trend has begun to emerge, with product theft events being reported in several areas of Europe, including in countries that had hitherto not been affected. Concawe found that its reporting system for pipeline spillages was not providing a complete picture of the scale of product theft, since it only captured theft events that resulted in a spill.
