Рассматривается вопрос о выборе оптимального плана эксплуатации технологического участка магистрального нефтепровода при различных производительностях. В качестве критерия оптимальности принимается минимум суммарных денежных затрат на оплату потребляемой электрической энергии. При изменении планов поставок нефти приходится решать вопрос, является ли новый вводимый режим оптимальным, какова будет величина требуемой дополнительной или неизрасходованной электроэнергии, какие поправки требуется вносить в заявку на электроэнергию. В этой связи определение корректного способа вычисления и сравнения энергопотребления при планировании режимов работы магистрального нефтепровода для разных, изменяющихся планов перекачки является актуальной и важной задачей. Предлагается двухэтапный алгоритм определения оптимального графика работы технологического участка нефтепровода путем решения задачи линейного программирования, сформулированной таким образом, чтобы учесть все особенности расчета стоимости потребленной электрической энергии. Приводится пример расчета с использованием предлагаемого алгоритма. The article considers the issue of choosing the optimal operating schedule for the technological section of the main oil pipeline at various pumping capacities. The optimality criterion is the minimum of total monetary expenses for payment of electric energy consumed for the oil pumping process. It is necessary to decide whether the new regime being introduced is optimal, what amount of additional or unspent electricity will be required, and how much it is needful to adjust the electricity demand when changing oil-pumping plans. In this regard, determining how to correctly calculate and compare energy consumption when planning the operation modes of the main oil pipeline for different, changing pumping plans is an urgent and important task. A two-stage algorithm for determining the optimal operating schedule of the oil pipeline technological section is proposed. The proposed method consists in solving a linear programming problem formulated in a way that takes into account all features of calculating the cost of consumed electrical energy. An illustrative example of calculation using the proposed algorithm is given.

The relevance of the study is substantiated by the fact that when managing the processes of oil transportation through main pipelines, it becomes necessary to determine and select the optimal operating modes of the oil pipeline units, taking into account the fuzziness of some part of the initial information. In this regard, solving the problem of multi-criteria selection of effective operating modes for an oil heating station for a hot oil pipeline system, which is often described in a fuzzy environment, based on the apparatus of fuzzy set theories, is an urgent scientific and practical problem. A method for the synthesis of models in the conditions of fuzzy output parameters of the object has been developed, with the help of which fuzzy models of the investigated oil heating station of the main oil pipeline have been built. Based on the modification and combination of various optimality principles, mathematical formulations of the problem of multi-criteria selection of effective operating modes for an oil heating station in a fuzzy environment are obtained. By modifying and adapting the principles of guaranteed results and equality in a fuzzy environment, a heuristic method has been developed for solving the formulated problem of selecting object's operation modes using the initial fuzzy information. The proposed heuristic method for multi-criteria selection in a fuzzy environment is based on the use of the experience and knowledge of the decision-maker. The proposed approach is implemented in the formulation and solution of the problem of multi-criteria selection of operating modes of the oil heating station in Atyrau of the Uzen-Atyrau-Samara main oil pipeline. As a result of the application of the proposed method, an improvement in the degree of fulfillment of a fuzzy restriction on environmental impact was achieved by 2 %, as well as the optimal values of the operating parameters of the object were improved: the temperature was reduced by 1.85 % (5.67 K), pressure – by 0.04 % (kPa) and fuel consumption – by 2.9 % (0.0002 kg/s). The obtained results have confirmed the effectiveness of the proposed approach to solving the assigned tasks.

The procedure for action in cases of a threat or an accident at oil pipeline transport facilities is defined in the relevant plans for emergency spillage prevention and response – ESPR. The purpose of the article is to analyze the requirements of the legislation in the field of development and approval of ESPR. The specifics of ESRP development at trunk pipeline facilities in Russia are noted, the US experience in combating oil and oil products spillage is presented. The problematic issues in the development and approval of ESRP, relevant for the domestic system of main oil pipeline transport, have been considered. It was established that the Federal Law No. 207-FL, adopted in July 2020, fundamentally changed the outdated and required revision approach to the coordination and approval of ESRP. At the same time, further work is needed to create a regulatory framework that establishes requirements for ESRP, as well as to improve ESRP, taking into account modern methods of predicting accidents, identifying emergencies, risk-oriented approaches to planning measures to localize and eliminate accidents, the specifics of operating organizations.

The problem of determining the repair sections of the main oil pipeline is solved, basing on the classification of images using distance functions and the clustering principle, The criteria characterizing the cluster are determined by certain given values, based on a comparison with which the defect is assigned to a given cluster, procedures for the redistribution of defects in cluster zones are provided, and the cluster zones parameters are being changed. Calculations are demonstrating the range of defect density variation depending on pipeline sections and the universal capabilities of linear objects configuration with arbitrary density, provided by cluster analysis.
