The oil pipelines have a strategic importance in the energy supply of the European Union (EU), especially given the fact that in the next two decades the crude oil will continue to be a dominant energy source, accounting for approx. 30% of the primary energy consumption, along with a reduction in the petroleum product consumption and growth in renewables. Europe has a widespread network of oil pipelines of approx. 22,5 thousand kilometres (without Russia), connecting refineries to import oil ports or to land-based crude oil sources. The refineries of the Central Eastern Europe are supplied mainly from the Druzhba oil pipeline. Recently, these refineries have diversified their crude oil supply routes and sources, by sea imports from the North Sea, the Middle East, Canada and others (Poland) or by the TAL – IKL oil pipelines (Czech Republic) and the JANAF oil pipeline (Hungary, Slovakia and the Czech Republic). Given the insufficient diversification of crude oil supply precisely of the Central Eastern European region, particularly the landlocked countries (and refineries respectively), the EU has envisaged, among the projects of common interests, also six connection oil pipelines with terminals. At the same time, they are the only pipelines planned to be constructed in Europe and financed by the oil companies’ funds. The oil pipeline and storage companies, as well as other oil companies, have a social responsibility as regards the energy supply, yet also a responsibility as regards their successful performance and development, thus investing considerable funds into modernisations, upgrades, protection, safety and security, etc. The oil pipeline companies hastily modify their strategies by expanding business and becoming more and more transport-storage-energy oriented, and by investing in the flow reversal of oil pipelines and connection pipelines, storage capacities, as well as in enhancement of efficiency and flexibility of oil pipeline and storage infrastructures.

Aim: The paper discusses cases in which a refusal by an energy enterprise to connect other enterprises to the network is treated as a prohibited abuse of the enterprise's dominant position and, equally, will represent behavior prohibited by art. 12 of the Treaty on the Functioning of the European Union and by art. 9 par. 2 item 2 of the Competition and Consumer Protection Law as well as legal consequences of such refusal. It is important to pinpoint such cases since the EU sectoral regulation does not provide for obligating any undertakings which manage and operate oil pipelines to enter into contracts with other undertakings such as contracts on connecting into their network or contracts on providing crude oil transfer services. Conditions for accessing oil pipelines and selling their transfer capacities are determined by the owners of the networks: private oil companies in the countries across which the pipelines are routed. These conditions are not governed by the EU law.  Furthermore, the very obligation of connecting other entities to own network by energy undertakings operating in the oil transfer sector in Poland will only arise from generally applicable provisions of the Polish competition law.  Design / Research methods: The purpose of the paper has been reached by conducting a doctrinal analysis of relevant provisions of Polish and EU law and an analysis of guidelines issued by the EU governing bodies. Furthermore, the research included the functional analysis method which analyses how law works in practice. Conclusions / findings: The deliberations show that a refusal to access the network will be a manifestation of a prohibited abuse of a dominant position and will be a prohibited action always when the dominant's action is harmful in terms of the allocation effectiveness. It will be particularly harmful when delivery of goods or services objectively required for effective competition on a lower level market, a discriminatory refusal which leads to elimination of an effective competition on the consequent market, a refusal leading to unfair treatment of consumers and an unjustified refusal. Originality / value of the article: The paper discusses the prerequisites which trigger the obligation to connect entities to own network by energy undertakings operating in the oil transfer sector. The obligation has a material impact on the operations of the oil transmitting undertakings, in particular on those who dominate the market. The regulatory bodies in the competition sector may classify a refusal of access to own network by other enterprises as a prohibited abuse of the dominant position, exposing such undertakings to financial consequences.Implications of the research: The research results presented in the paper may be used in decisions issued by the President of the OCCP and in judgement of Polish civil courts and EU courts. This may cause a significant change in the approach to classifying prohibited practices to prohibited behavior which represent abuse of the dominant position. The deliberations may also prompt the Polish and EU legislator to continue works on the legislation.

A mathematical model is established for the preheating commissioning process of waxy crude oil pipelines. The governing equations are solved by the finite volume method and the finite difference method. Accordingly, numerical computations are made for the Niger crude oil pipeline and the Daqing-Tieling 3rd pipeline. The computational results agree well with the field test data. On this basis, fluid temperature in the process of the preheating commissioning is studied for single station-to-station pipeline. By comparing different preheating modes, it is found that the effect of forward preheating is the best. Under different preheating commissioning conditions, the optimal combination of outlet temperature and flow rate is given.

A significant part of the oil consumed in the world is transported from production and processing sites to consumers via tankers and pipelines. According to experts' forecasts, the demand for oil and petroleum products in the coming years will be significantly higher than in 2020. In Russia, the oil transportation market is developing in several directions. The main directions are investing in pipeline transport and improving the design of tanks for storing oil and petroleum products. The article considers the contribution of the great Russian engineer V.G. Shukhov to the solution of the problem of oil transportation and storage and in general to the development of the oil industry. In the article "Oil Pipelines" (1884) and in the book "Pipelines and their application in the oil industry" (1894), V.G. Shukhov gave precise mathematical formulae for describing the processes of oil and fuel oil flowing through pipelines, creating a classical theory of oil pipelines. He is the author of the projects of the first Russian main pipelines: Baku-Batumi with a length of 883 km (1907) and Grozny-Tuapse with a length of 618 km (1928). Shukhov V.G. designed and then supervised the construction of oil pipelines of the companies "Branobel", "G.M. Lianozova and sons" and the world's first heated fuel oil pipeline. Working in the oil fields in Baku, Shukhov V.G. developed the basics of lifting and pumping oil products, proposed a method of lifting oil using compressed air — airlift, developed a calculation method and technology for the construction of cylindrical steel tanks for oil storage facilities.

Operation Parameters

Based on the technological requirements related to waxy crude oil pipeline transportation, both unavoidable and avoidable destroyed exergy are defined. Considering the changing characteristics of flow pattern and flow regime over the course of the oil transportation process, a method of dividing station oil pipelines into transportation intervals is suggested according to characteristic temperatures, such as the wax precipitation point and abnormal point. The critical transition temperature and the specific heat capacity of waxy crude oil are calculated, and an unavoidable destroyed exergy formula is derived. Then, taking the Daqing oil pipeline as an example, unavoidable destroyed exergy in various transportation intervals are calculated during the actual processes. Furthermore, the influential rules under various design and operation parameters are further analyzed. The maximum and minimum unavoidable destroyed exergy are 381.128 kJ/s and 30.259 kJ/s. When the design parameters are simulated, and the maximum unavoidable destroyed exergy is 625 kJ/s at the diameter about 250 mm. With the increase of insulation layer thickness, the unavoidable destroyed exergy decreases continuously, and the minimum unavoidable destroyed exergy is 22 kJ/s at 30 mm. And the burial depth has little effect on the unavoidable destroyed exergy. When the operation parameters are simulated, the destroyed exergy increases, but it is less affected by the outlet pressure. The increase amplitude of unavoidable destroyed exergy will not exceed 2% after the throughput rises to 80 m3/h. When the outlet temperature increases until 65 °C, the loss increase range will not exceed 4%. Thus, this study provides a theoretical basis for the safe and economical transportation of waxy crude oil.

Oil Pipelines

For a new buried heated oil pipeline, the temperature field of the surrounded soil is natural. Therefore the temperature is usually low in this case. For the waxy crude oil whose pour point is higher than the ground temperature, if the new pipeline transports such oil directly after heating, crude oil may gel in pipeline because its temperature decrease dramatically due to heat exchange between the fluid and the surrounded soil. Hence, in practical situation hot water is often used to warm up the pipelines for most of the new long-distance buried pipelines. Crude oil transportation is determined after the soil temperature field around the pipeline is sufficiently high and the inlet water temperature meets the requirement.

Major Consideration

The idea to construct a pipeline from Suez to the Mediterranean (SUMED) was initially raised before the 1967 War. With the closure of the Suez Canal following the war, the pipeline could offer a less expensive route for Gulf oil. However, the pipeline was inaugurated only in 1977, following three wars and debilitating negotiations between Egypt and foreign institutions. This article analyzes the motives for the project as well as the reasons for the long delay in its implementation. Anticipated financial profits were a major consideration for both the governments concerned and the oil companies. Yet the project was launched only after the parties involved realized that its construction also entailed significant political advantages and after the security risks were eliminated. In recent years, SUMED and the Suez Canal have become major transportation routes for crude oil, transforming Egypt into an actor in the oil market.

This paper addresses the specific issues of transient leak detection in crude oil pipelines. When a leak occurs immediately after pumps are switched on or off, the pressure wave generated by the transients dominates the pressure wave that results from the leak. Traditional methods have failed to detect such leaks. Over the years, NWO has developed and implemented various leak detection systems both in-house and by commercial vendors. These systems work effectively under steady-state conditions but they are not able to detect leaks during transients. As it is likely for a leak to develop during transients, NWO has decided to have the ATMOS Pipe statistical leak detection system installed on their pipelines. This paper describes the application of this statistical system to two crude oil pipeline systems. After addressing the main difficulties of transient leaks, the field results will be presented for both steady-state and transient conditions.

Consumption Prediction

Abstract Energy consumption prediction plays an important role in pipeline operation regulation and energy management. Accurate energy consumption prediction is helpful to make important decisions, including unit commitment, batch scheduling, load dispatching, energy consumption target setting, etc. The energy consumption of crude oil pipeline is mainly the electrical energy of pump unit. The average annual electrical energy consumption of China’s crude oil pipelines accounts for more than half of the annual operating cost of pipelines. Therefore, the prediction of electrical energy consumption of crude oil pipelines is critical. The energy consumption prediction of crude oil pipelines is very complicated. Firstly, it depends on the variables related to operation parameter, crude oil physical property parameter, environmental parameter and equipment parameter. Secondly, its nonlinearity is strong. Thirdly, the available samples are too little. Through the study on the monthly operation data collected by the Supervisory Control And Data Acquisition (SCADA) system and energy consumption analysis, the turnover and the electrical energy consumption is selected as input variable and output variable, respectively. The support vector machines (SVM) is introduced to predict the monthly electric energy consumption of crude oil pipelines driving oil pumps. However, the generalization capability of SVM is highly dependent on appropriate parameter setting, such as penalty coefficient and kernel parameter. The selection of the optimal parameters is critical to achieving good performance in the learning process. Therefore, in order to improve the generalization ability, GridSearchCV was adopted to optimize the hyperparameters of SVM. Taking a crude oil pipeline from Qinhuangdao City, Hebei Province to Fangshan District, Beijing as an example, the actual operation data for four consecutive years (48 months) are used for this study. The data are divided into training set and test set by stratified sampling method, which consist of 28 samples and 20 samples respectively. The mean absolute percentage error (MAPE), root mean square error (RMSE), mean absolute error (MAE) and coefficient of determination (R2) on the test set are 3.42, 21.64, 14.31 and 0.94 respectively. Compared with other five state-of-the-art prediction methods in predictive accuracy, the result shows that GSCV-SVM has the best performance in the case of small samples, and the prediction results are in good agreement with the actual data.
