Authors: Shershneva M V , Bodenko E M 
Published: February 2022

Abstract
The relevance of the problem under study is due on the one hand to the need to reclaim disturbed areas formed as a result of construction activities, on the other hand to the need to find useful use of demolition products of buildings and structures. The purpose of the work is to study the possibility of using multimodal logistics for the use of demolition products in the reclamation of disturbed areas, using the example of granite quarries. Geoecological, technological and economic forecasting of multimodal logistics of urban agglomeration demolition products will allow to develop the most optimal schemes of their useful use. As a result of research, mathematical models have been developed for predicting the formation of a transport and logistics chain for the removal of demolition products from objects. For the first time, a scheme has been developed for choosing a method of moving demolition products depending on the range of the burial place for making substantiating decisions on their removal in the process of designing measures for the reclamation of granite quarries from the point of view of geoecological and economic expediency. It is scientifically justified to use demolition products as fillers of spent granite quarries for temporary storage, partial or complete filling with subsequent reclamation of spent quarries. The materials of the article can be useful for the development of technological solutions for the reclamation of disturbed areas using demolition products of buildings and structures.

Abstract
The management of industrial safety and occupational health associated with oil and gas production is one of the vital components of the oil and gas industry, since it is well known that most conditions of operation, processing and storage of chemicals and end products pose a serious threat to technological and environmental safety, as well as health and life of people. The main danger is posed by potential explosions and fires occurring in the places of storage and transportation of oil products, which requires constant improvement of safety methods in the industry.
Hierarchical Representation of Decision-Making in Chartering a Vessel on a Voyage Charter
Authors: Kiseleva E V , Stepanets V E , Pilyugin A G , Valkova S S 
Published: February 2022

Abstract
This paper presents a decision-making method (analytic hierarchy process) for choosing a charter option by means of a subjective preference vector. Analytic hierarchy process (AHP) is a rather general methodology for solving a broad range of weakly structured decision-making problems that combines a fairly simple mathematical method with the manager’s knowledge, experience, and imagination. This paper investigates AHP application by a manager who is not an expert in chartering. To describe the method, the paper presents a case study of chartering a vessel to freight bulky, heavy cargo.
Technology of Water Purification from Hydrogen Sulphide and Its Utilization
Authors: Tereshchuk V S , Rakov D L 
Published: February 2022

Abstract
The article discussed a technology for cleaning natural reservoirs from hydrogen sulphide to improve the environment. The choice of research methods was to organize the creation of an airlift due to the electrolysis of seawater. To purify seawater from hydrogen sulphide, electrolysis with the release of hydrogen and oxygen is used. The released gases create an airlift effect, due to which the hydrogen sulphide rises to the surface, where it is captured for further separation. By-products of the electrolysis of seawater, chlorine and sodium, due to their good solubility in water, are converted into alkali and acid and, as a result of the neutralization reaction, return to the reservoir. The paper also discusses the features of the electrolysis of seawater. The use of the proposed approach will improve the ecological situation and, in particular, will lead to an increase in fish stocks and in the restoration of the red algae population.

Wastewater Treatment for Mercury and Arresting Mercury Contaminants Movement Within Industrial Soil
Authors: Fuchs S L , Filatov V Y , Devyaterikova S V 
Published: February 2022

Abstract
We have proposed optimal methods of treating both the waste- and stormwater for metallic and soluble mercury within the soil of mercury-based chlorine- and sodium-hydroxide production sites. The problem has been solved by combining physical, chemical and physicochemical treatment methods. Through the use of various filtering materials, coagulants and flocculants followed by sorption through AB-17-8 and Lewatit TR-214 ion exchangers, the level of mercury within wastewater has been decreased by about 99.9%. Demercurization of mercury-contaminated areas to the complete extraction of metallic mercury has been carried out by draining and the subsequent transfer of water-based compounds into a stable form through chemical immobilization without any prior soil removal. To achieve the aforesaid result we have treated the soil with stearic-acid salts solutions, which resulted in almost complete arrest of mercury within the soil.
Application of Demolition Products of Buildings and Structures to Ensure Reduction of Concentration of Heavy Metal Ions in Man-Made Soils at Construction Facilities
Authors: Shershneva M V , Bodenko E M 
Published: February 2022

Abstract
The article considers the problem of soil contamination in St. Petersburg with heavy metals. It has been shown that the degree of contamination is such that soils lose their ability to self-clean and can be attributed to technologically modified soils. Geochemical barriers are required to reduce the concentration of heavy metals. Based on the principle of A.I. Perelman, it is shown that the most promising wastes of the construction industry for use in geochemical barriers are silicate-containing wastes from demolition of buildings and structures. Capacity of heavy concrete and aerated concrete in relation to some heavy metals is determined in the work. The absence of selectivity of wastes to various heavy metals is shown. The formula for calculation of the life of the geochemical barrier taking into account its size, capacity and amount of contamination coming with melted and rain drains is proposed. The life of the geochemical barrier is calculated to prevent the migration of iron ions in the form of a railway embankment, which amounted to 47 years, provided that granite crushed stone is completely replaced by heavy concrete.
Clustering of Marine Vessel Trajectory Data for Routes Planning through Water Areas with Heavy Traffic
Authors: Grinyak V M , Shulenina A V , Devyatisilnyi A S 
Published: February 2022

Abstract
The article is devoted to the problem of ensuring the safety of vessel traffic. One of the elements of the traffic organization in areas with heavy navigation is the system of establishing the routes of vessels. This system is a set of restrictions imposed by a certain traffic pattern and rules adopted in a particular water area. The paper considers the problem of planning a transition route for water areas with heavy marine traffic. The planning of the vessels transition route during the movement of the water area with established routes must be carried out taking into account the specified restrictions. A possible way to identify these restrictions is to isolate the movement patterns of a particular sea area from the retrospective information about its traffic. Model representations of such a problem can be formulated on the basis of the idea of clustering the parameters of traffic. The route planning problem model is based on finding the shortest path on a weighted graph. Several ways of constructing such a graph are proposed: a regular grid of vertices and edges; a layered ore random grid of vertices and edges; vertices and edges based on retrospective data. The weight of the edges is proposed to be set as a function of the “desirability” of a particular course of the vessel for each point of the water area, taking into account the identified movement patterns. The paper discusses possible clustering methods and makes a choice in favor of subtractive clustering.
Geoecological Assessment of Resources of a Water Body for More Optimal Use
Authors: Ivanchenkova O A , Levkina G V , Romanenko A A 
Published: February 2022

Abstract
This paper presents a geoecological assessment of resources potentially available in or from shallow water bodies. It describes a case study as an example of how water bodies and coastal areas could be comprehensively analyzed, including microbiological testing, physical and chemical tests, testing water and bottom sediments for heavy metals, gamma spectrometry of soil samples, hydrological and hydroeconomic estimates. Experimental data is used to analyze the status of water bodies. Apparently, microbiological indicators are within the acceptable limits, and so are heavy metals. However, water sampled from Lake Oktyabrskoye has >10 times limit chromaticity and turbidity indicators, 10-11 times the limit chemical oxygen demand (COD). This indicates severe pollution and high concentration of organic substances. The presented approach to resource assessment could be of use when devising measures for nature-friendly restoration of water bodies.

Computer Modeling of Zn and Ni Distribution in Technogenic Soils
Authors: Sarapulova G I 
Published: February 2022

Abstract
Based on computer modeling using geochemical parameters, new results of the interdependent distribution of mobile forms of heavy metals Zn and Ni in contaminated soil have been obtained. Modeling in Golden Software SURFER 8 made it possible to identify soil contamination halos - laterally module - in the zone of a hazardous gas station facility in the city. A three-dimensional skeleton model of the distribution of mobile forms of HM was obtained depending on the key parameter of soil organic carbon - Corg. The revealed picture of the distribution of metals adequately reflects the specificity of the individual chemical properties of Zn, Ni and clearly demonstrates the different efficiency of binding of their mobile forms with soil organic matter. The proposed approach of computer geochemical modeling can be recommended as a methodological guide for identifying the characteristics of behavior in the soil environment for other heavy metals. The revealed empirical dependencies prove the need to change approaches in the ecological assessment of territories in the conditions of technogenesis. Research also has a promising development, allows one to obtain new geochemical patterns and associations of elements in technogenic landscapes, which contributes to the development of the fundamental foundations of geochemical science.
Analysis and Traffic Management in Smart Cities
Authors: Namiot D , Pokusaev O , Chekmarev A 
Published: February 2022

Abstract
This article examines the issues of traffic management in the city. It is well known that cars are a significant contributor to urban air pollution. Accordingly, the management of transport in the city is one of the imperative tasks in terms of supporting the environment and ensuring urban development. Such management is impossible without collecting information on traffic flows in the city. It is logical to assume that there should be a single data source (information store) that contains information about all shipments. Urban governance, of course, involves not only collecting and analyzing data, but also managing this process. This article is devoted to the discussion of such systems.
Estimation of the Influence of Oil Flows on the Formation Losses of Condensate During the Development of Multi-Layer Deposits
Authors: Katanova R K , Inyakina E I , Alsheikhly M D Z , Krasnov I I 
Published: February 2022

Abstract
During the development of multilayer oil and gas condensate fields, the production of condensate is influenced by the associated oil. Analysis of field data showed that the cause of oil flows is the outstripping decrease in reservoir pressure in the gas condensate section in comparison with oil zones. Thus, incoming heavy oil fractions into a gas condensate reservoir have a negative impact on reservoir losses of hydrocarbons, including the final condensate recovery factor. Many years of experience in the development of such fields showed that the bulk of the presence of associated oil in well production is explained by the following reasons: the relationship between the reservoirs through lithological windows, the residual oil saturation of the reservoirs, and the presence of lenticular layers. Determination of the quantitative content of oil in the reservoir mixture was determined by infrared spectrometry using a Perkin-Elmer Fourier transform spectrometer, which makes it possible to assess changes in the component composition of gas condensate systems. In the course of the research, selected samples of the gas and liquid phases were analyzed directly from the production facilities of the development. The analysis of IR spectrometry showed that in most of the samples of gas condensates, the effect of displacement is recorded, which is characteristic of fluids with the manifestation of oil impurities.
The purpose of these studies is to study the influence of the produced oil on the dynamics of hydrocarbon production and the final condensate recovery factor.

Authors: Knaub R V , Ignateva A V 
Published: February 2022

Abstract
The article presents a possible mechanism for the occurrence of natural disasters on a global scale based on the view of the Earth as an evolving electromagnetic self-oscillating system. The possible future of natural disasters in the global dimension is presented. It has been established that for the period from 1900 to 2020 there was a gradual, and at certain time intervals and a sharp increase in the number of catastrophes on our planet. At the same time, there was an increase in the number of victims of these disasters, the number of victims and material damage. The article emphasizes that catastrophes for our planet are a natural course of development for it as for an evolving electromagnetic self-oscillating system. For this reason, all natural disasters on our planet must be adequately accepted and understood that only for humans they are catastrophes, and in the event of human losses and economic damage, they pass into the stage of emergency situations. The article also shows a close connection between natural disasters and the rhythms of the Sun and solar activity.

Published: February 2022

Abstract
The article discusses an approach to calculating the characteristics of soil erosion near the support foundations of ocean-technical structures under the influence of wave and constant currents. Vertical supports in the form of a circular cylinder are considered a support base. An example of the choice of the initial and boundary conditions for the calculation is given. Simulation is carried out near the cylindrical support. The results obtained were compared with empirical data. Conclusions are drawn about the displacement of the zones of maximum and minimum velocities during wave movement. The spatial distribution of the amplitudes of the wave velocities was calculated. A decrease in the amplitude in the rear part of the cylinder and immediately in front of its frontal part was revealed, and it was also determined that the zone of an increase in the amplitude was formed near the lateral surfaces of the cylinder.

Published: February 2022

Abstract
The article presents a methodology for evaluating the efficiency of oil industry waste recycling systems using multi-layer artificial neural networks. As an indicator of the efficiency of the recycling system, the indicator of the resource value of oil-contaminated waste (OCW) is used. For training neural networks, the data sets are formed using the resource value assessment algorithm based on the Data Envelopment Analysis (DEA) method of multi-factor evaluation of the efficiency of production systems. The development and training of neural networks are performed using the free software Neuroph Studio. A comparative analysis of the quality of the assessment of the OCW resource value depending on the size and number of layers in a multi-layer neural network is carried out. The obtained results demonstrate the prospects of the proposed approach. Recommendations for improving the accuracy of resource value assessment by an artificial neural network are given.

Published: February 2022

Abstract
The article is devoted to the problem of navigation safety of sea vessels’s movement. An approach is considered that allows generating alarm signals with the allocation of various levels of danger. The criterion for the division of hazard levels is based on the trajectory properties of the movement of ships. A system of rules is proposed, which appeals to model representations of the “ship-to-ship” type and allows to streamline the actions of the dispatcher when controlling the collective movement of ships. The results of modelling and field study of traffic in the water area of the port of Vladivostok, which confirm the constructiveness of the proposed ideas, are presented.

Authors: Ivanyo Ya M , Petrova S A , Kovaleva E A 
Published: February 2022

Abstract
The article proposes an ecological-mathematical model to optimize the production of agricultural products, taking into account the risks associated with climatic events. The model describes a combination of crop and livestock production on irrigated and non-irrigated agricultural land. In this model, the target function characterizes the maximum income and damage to the environment as a result of farming in conditions of natural risks. Restrictions describe the availability of land and labor resources, production volumes, soil and water pollution, erosion of agricultural land, the combination of crop and livestock products in conditions of severe droughts or heavy rainfall. When implementing the model, a special case was considered: an ecological-mathematical model for non-irrigated lands, taking into account severe drought. The proposed model is implemented on the example of an agricultural enterprise in the Irkutsk region, which is subject to significant risks caused by extreme climatic events, primarily drought.
