Purpose – The purpose of this paper is to explore how change is brought about in quality governance of Baltic maritime oil transportation. Design/methodology/approach – This qualitative case-study sought to understand the underlying mechanisms of quality governance. The paper analyzed versatile empirical material (including expert interviews) to uncover how a particular constellation of public and private, binding and voluntary, internal and external quality standards impacted the process of institution building for quality management in Baltic oil shipping. Findings – The paper shows that emergence of quality practices in oil shipping is associated not only with the development of shipping industry as a whole, but also with the dynamics within the energy value chain. The findings suggest that alignment between rules and incentives is specific to a combination of given natural, political and economic contexts as well as physical infrastructure which set applied limitations upon the governance process and, eventually, impact the set of quality governance mechanisms available for use. Research limitations/implications – The paper shows that collective action is contextually-bound, thus the mechanisms of quality shipping governance can essentially differ from one locality to another. This implies that local solutions can be found to problems conventionally identified as global. Practical implications – Paper’s findings question the applicability of “one-size-fits-all” approaches to policy-making and calls for more targeted regulation. The research also stresses the role of technical modernization in prompting actual change in regards to quality practices. Originality/value – This research claims that transition to sustainable transportation systems requires institutions that are capable of linking actors and contexts in a way that balances supply and demand for quality.

Purpose This paper aims to analyse the key trends in oil delivery and production and evaluate the capacities of crude oil transportation systems in the Western European region. Design/methodology/approach To meet these goals, qualitative data analysis was used to assess the contribution of countries in the region to the total crude oil production and delivery, the changes in concentration of crude oil deliveries and refineries’ capacities, the capabilities of the regional crude oil transportation system and the trends in crude oil supplies and processing from 2005 to 2015. Findings The study established that from 2013 to 2015 oil supply to the region’s refineries increased and generated additional stress on the transportation and refining infrastructure. Research limitations/implications This study examined the aggregate values of crude oil production, crude oil deliveries and refining capacities. In practice, different refineries are set to process certain types of crude oil. It is possible to use the described approach with a certain crude oil grade. Practical implications When developing the programmes for crude oil supply to refineries, it is vital to take into account the capacities of refineries and the capabilities of the crude oil transportation systems. Originality/value The study suggests that the region’s infrastructure has the necessary reserves to operate for the next few years without additional investments.

Transportation of oil via main pipelines often requires the need for a permanent or periodic dumping of some part of the flow for further shipment of crude oil to oil refineries or filling stations. The application of such technology leads to a change in the operating mode of oil pumping stations and the oil transportation system in general. In case of emergency, an analogue of dumping is an oil leak from the pipeline in a case of violation of its integrity. Resetting a part of the flow is accompanied by a change in a liquid flow ahead of and behind the discharge point, which inevitably leads to a redistribution of pressures at the inlet and outlet of transitional petroleum pumping stations. Increasing of pressure at the output of the stations may lead to the violation of the pipeline strength; reducing of input shoring may cause cavitation operating modes of the equipment. Therefore, the study of the impact of discharges on the parameters of the operation of oil transportation systems in order to ensure their reliable, safe and economically efficient functioning is a relevant point of this area. For this purpose, based on the proposed calculated algorithms implemented in the software, the authors conducted the research on the impact of periodic oil discharges on the redistribution of hydraulic flows, energy losses at the bends, pressure at the inlet and outlet of oil pumping stations, as well as the volume of trunk oil pipelines capacity. The approbation of the proposed elaboration is carried out by defining the operational parameters of processing in functioning of oil and transport system «Druzhba» at the Mozyr-Tukholsky pass, which runs throughout the territory of Ukraine. Based on the analysis of the obtained results it was established that, depending on the volume of a discharge, the location of the limiting area, which limits the entry capacity of the trunk pipeline in general, might be changed. At the same time, the bend, ahead of which the part of oil is discharged, is not always limiting. Increasing the volume of a discharge leads to growing capacity of the pipeline at the area ahead of the point of discharge in the case when the limiting pipeline bend is behind the discharge point. If such a bend is located on the pipeline ahead of the discharge point, the increasing discharge does not affect the capacity of the initial area of the pipeline.

The actual scientific and practical task, which consists in the analysis of existing and development of new methods and methods for assessing the technical condition of main oil pipelines, which will ensure safe automated management of the oil transportation system, is researched. It has been determined that in conditions of intensive aging of fixed assets of oil transportation systems and financial constraints, comprehensive technical diagnostics of main oil pipelines becomes the most effective means ensuring the reliability and safety of the entire oil transportation system. That is why the development of new and promising means of control and management on the basis of artificial intelligence is an actual scientific and practical task, the results of which identify the main scientific problems that require further research.

Modern oil transportation systems are characterized by a complex hydraulic structure and geometric configuration, and often require the need for a permanent or periodic pumping or dumping part of the oil flow. The implementation of such transportation technology necessarily leads to changes in the operating conditions of oil pipelines and in accordance with the need to regulate the operation of oil pumping stations. Consequently, determining the patterns of the impact of the process of dumping the part of the oil on the energy parameters of the operation of oil transportation systems is an extremely important task.The influence of periodic dumping the part of oil on the energy efficiency of the operation of main oil pipelines was studied. The impact of volume of discharges on the consumption of power on pumping oil in the system of the main oil pipeline was analyzed. It has been found that with the increase the volume of discharges, the specific consumption of electricity for oil pumping decreases.Based on the carried research, the recommendations on the selection of reliable, safe and optimal pumping modes in terms of cost of electricity for the operation of oil pipelines "Druzhba" in the direction of Mozyr - Brody - Tukholsky pass with periodical partial oil dumping on LPDS "Brody".

In prehistoric ages, mankind needed transportation but not transportation systems. In recent times, accompanying the development of human activities, the importance of transportation and transportation systems has increased more and more. By the word "transportation", the author means the spatial transfer of human beings, materials and articles and by the word "transportation system", he means a system of structures, facilities, and equipment effectively transferring human beings, materials and articles. So, highway systems, railway systems, air transportation systems, marine and river transportation systems, water supply and sewage systems and fuel and oil transportation systems are included as transportation systems.
