A retrospective analysis of the development of transboundary territories in terms of transported goods of various nomenclature for a certain period was carried out. The stages of the development of cargo transportation of the Omsk region - Kazakhstan cross-border territory from the middle of the XX-XXI centuries were determined. Possible directions for the development of transboundary territories have been identified. A number of limitations have been identified that make it difficult to investigate individual issues. The need to increase the share of water transport in the total volume of transported goods is indicated, taking into account the emerging positive trends in the field of cooperation with other countries.","PeriodicalId":145731,"journal":{"name":"Russian Journal of Water Transport","volume":"133 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139174868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each of the presented graphs refers to a certain horizontal clearance and heading angle, as well as the number of intermediate stabilization columns. According to the obtained graphs, it is possible to estimate the power of the power plant, mainline and shunting engines of a semi-submersible floating crane of the selected design scheme at the initial stages of design.

A cartographic study of transport links through rivers and their catastrophic shortage in comparison with demand has been carried out. A completely new concept of a ferry crossing for one car has been proposed. The driving mechanism of the ferry movement from the driving pair of wheels of the car with different variants of propellers and control systems has been developed. The overall and displacement parameters of the vessel are determined according to the requirements of small-size shipbuilding. In the Compass-3D package, a three-dimensional model of the ferry, all working units of the mechanism and control was created, and the mass-centering characteristics were calculated. A comparative assessment of the mechanical parameters of the presented propellers was carried out: the screw-steering column and the paddle wheels. Mechanisms with manual and automated control modes are described and compared.","PeriodicalId":145731,"journal":{"name":"Russian Journal of Water Transport","volume":"77 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138978958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the conditions of a large range of directions, there is a need to apply single-layer or multi-layer structures to the properties of sound insulation without forming a physical model of the hood, casing. This is due to the fact that the production of a hood model entails a complex technological process, while creating a sample in the form of a plate from the same material is much more profitable in terms of financial, labor and time costs. Based on the needs of the scientific educational and production laboratory of outboard boat motors in the study of noise generated by outboard boat motors and means of combating them, it was decided to create a stand to assess the effectiveness of noise-reducing materials, which will allow modeling the conditions of natural operation of a noise-insulating material without the use of full-scale tests with outboard by motor. The created stand allows testing in two directions. The first direction is the testing of physical models of casings for noise insulation using audio files reproducing the noise of the required equipment.

The practice of using alternative fuels indicates that their physicochemical properties make significant adjustments to the way the internal combustion engine workflow is organized and have a very significant impact on the effective and environmental performance of the engine and the entire power plant as a whole. The main task of designing a power plant with an internal combustion engine running on synthesis gas is to provide the necessary power, minimum fuel consumption in various operating modes, as well as minimum emissions of harmful substances into the environment, depending on the composition of the synthesis gas. It should be noted that the specific heat of combustion of synthesis gas is lower compared to traditional grades of fuel (25...30 MJ/kg), this leads to a significant reduction in the power of the marine engine. It is this factor that determines the use of synthesis gas as an additive to traditional fuel. Analysis of the available results and modeling of the combustion processes of liquefied natural gas on ships will allow to predict and determine further ways to improve fuel efficiency, power indicators and ecology of engines running on ethanol with forced ignition.","PeriodicalId":145731,"journal":{"name":"Russian Journal of Water Transport","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116349319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is of particular importance for the northern and eastern regions, where the density of railways and highways is not high enough, or they do not exist at all. In these regions, the share of river transport in the total cargo turnover is about four percent. The use of river water transport for military purposes will never be stopped. Since requirements that are more stringent are imposed on military transport, the decommissioning of these vessels is faster than in commercial use. In most cases, the technical condition of the vessel is not critical, and it can be further operated. In view of the fact that recycling is a rather expensive process, ships are idle and are not used for their intended purpose. The way out of this situation can be the use of decommissioned military vessels for commercial purposes by converting them into a refrigerator in order to extend the operational life of the vessel, improve the technical and economic indicators of the vessel and make a profit. From the point of view of the methodological approach, the analysis of existing refrigerated containers was carried out, additional devices for converting electricity were given, the technological process of manufacturing the frame of the refrigerator installation was developed, and its strength calculation was carried out. The economic feasibility of converting the vessel into a refrigerator is shown.","PeriodicalId":145731,"journal":{"name":"Russian Journal of Water Transport","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116056592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main purpose is to check whether the proposed machine can meet the operating parameters specified in the specification. This chapter begins with a description of a current exciter with protruding poles and a description of a design with teeth. The toothed stator is also distinguished by being made of an inexpensive ferromagnetic material such as cast iron. When choosing cast iron, they are guided by the fact that it is already used in industry in other components of alternators, such as bearings and some connecting bushings. The use of cast iron also reduces eddy current losses compared to solid steel parts. Since the path of the magnetic flux in the stator is three-dimensional, the study is carried out using software for 3D finite element calculation. The model of the machine is compared with the experimental results obtained on the layout. Then we make changes to the geometry of the machine to improve its characteristics.
