From the history of the problem of oil transportation and storage. Contribution of Shukhov V.G.

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.

Cost-effectiveness analysis of tank and base foundation diagnostics without paintwork removal

The article describes the particular qualities of application of a cylindrical steel tanks' and base foundation technical inspection method without removal of a protective covering. The model is formed and the basic parameters of an estimation of economic efficiency of carrying out of diagnostics are determined. The economic efficiency of application of the modern method of vertical steel tank examination is estimated. The high economic efficiency of the new technological method is substantiated in comparison with the traditional method. It is established that the advantage of using the innovative diagnostic method in comparison with the traditional method is fully manifested when it is necessary to maintain a large fleet of tanks. It is calculated that, given the design parameters, the savings in the use of the method proposed by the authors in the long term are 1773.2 million rubles compared with traditional. The use of a new technological method - the technology of diagnosing vertical steel tanks without removing the protective coating, allows to reduce the total cost of conducting diagnostics with a discount of 8.7 times. Dependences were obtained of the discounted volume of expenses on acquisition of the equipment and the subsequent diagnostics of vertical steel tanks on the operation time of the vertical steel tanks.

Improving proposals for design standards of vertical cylindrical steel tanks for oil and oil products storage

The calculation of subsidence points along the contour and in the center of the tank bottom is complicated in the case of erosion on inhomogeneous, subsidence, damaged soils, mules, flooded and seismically dangerous areas. The article analyzes the most dangerous geological phenomena, processes and complicated geotechnical conditions for the territory of Ukraine. The method of an artificial base arrangement with improved properties due to vertical reinforcement by soil cement elements is considered. Techno-economic comparison of the proposed variant with the usual pile variant of foundations (subsidence soils, estimated seismic intensity of 9 points) has been carried out. Probabilistic analysis of the artificial base has been carried out and the corellation between the probability of its failure from the percentage of reinforcement has been determined.
