Analysis of modern hull structures dry cargo ships-representatives

The results of the analysis of the design of hull structures of modern dry cargo vessels-representatives of inland and mixed ("river-sea") navigation in comparison with classical vessels built in the twentieth century are presented. The characteristic damages of hull structures are considered, recommendations are given on the design of the main hull connections in accordance with the requirements of the Russian River Register (RRR) and the Russian Maritime Register of Shipping (MRS). It is noted that, taking into account the existing cargo flows on water transport, the hulls of inland navigation vessels of early construction are being modernized for operation in coastal marine areas. It is shown that, taking into account the aging of the fleet in modern conditions, a significant role is assigned to the construction of "super-full" vessels of internal and mixed ("river-sea") navigation, capable of delivering various cargoes without intermediate transshipment from seaports to river ports of the country.

Techno-economic aspects and problems of the rotary rowing units introduction in the modernization and construction of ships (on the example of projects 1809 and CNF11CPD)

The article contains a detailed analysis of studies related to the use of existing and new principles of fuel economy, and reducing the cost of re-equipment and operation of vessels of the above projects. The authors of the article did not set out to analyze the technical features of these projects. Only by linking to these projects, the analysis was done for the entire fleet of this type as a whole. A technical and economic analysis of the characteristics, modeling of the main and auxiliary installations in the Matlab package, providing fuel economy on the example of ships of projects 1809 and CNF11CPD, is carried out. Then a physical simulation was carried out. As a result of testing a vessel with a rotary rowing electric installation (RSEU), a qualitative analysis of the data obtained was carried out, conclusions were drawn that allow us to judge the possibility of large-scale use of such installations in maritime transport.

Technical indicators of modern trawlers

The article identifies the problem of the lack of up-to-date publicly available statistical information on the technical and economic performance of modern fishing vessels, including foreign mining vessels, which entails serious restrictions on the choice of a prototype, from which domestic authors are forced to use outdated indicators of ship designs built in the second half of the XX century. The methods of obtaining the necessary information using the open databases of the Global Fishing Watch organization are presented. The methods of the organization's work with information and the characteristics of some databases are described. The data has been processed for further use. According to one of the fishing criteria, the most effective trawlers of 2020 were selected. Thanks to the obtained statistics on the operation of trawlers, it was possible to obtain many technical indicators of the vessels ' operation: the operating mode, the structure and duration of the fishing voyage, the form of fishing organization, the balance of calendar time. As the statistics are processed, the results are analyzed. The observations made are described: about the round-the-clock operation mode; about the duration of storming; about the associated fishing. The obtained indicators were compared with the indicators of trawler factories in 1969. The necessity of continuing the study of the main technical and economic indicators of modern fishing vessels: income, expenses, profit is justified.

Assessment of tribotechnical properties and resistance to wear of plasma coatings

In order to determine the operating conditions of parts for which restoration of worn surfaces is acceptable by the method of plasma spraying of various powder alloys, contact fatigue tests were carried out under cyclic contact impulse loading. In addition, tribotechnical tests were carried out with various wear-resistant coatings under conditions of liquid sliding friction. Bench and operational tests showed the use of coatings obtained using modern plasma technologies, the feasibility of protecting parts operating in conditions of corrosion, waterjet and cavitation wear, as well as in sliding friction. The coating sprayed with Ni-Al intermetallic alloy powder provides the most reliable protection against shock cyclic impact and abrasion during liquid friction than other materials studied. Coating with wear-resistant self-fluxing powder Ni-Cr-B-Si-C alloy, hardened by solid carboboride phases, without its additional heat treatment for restoration of surfaces working in sliding friction pairs, is not recommended.

Features of the infocommunication infrastructure development management mecha-nism

In the context of the Industrial Revolution 4.0 and the total digitalization of socio-economic processes in society, research related to the development and justification of effective mechanisms for managing the innovative development of modern infocommunication infrastructure and ensuring a high level of efficiency of the practical application of infocommunication technologies (ICT) is relevant. The most important feature of the evolution of such infrastructure and the ICTs themselves is their significant correlation with the totality of processes carried out in the global and national economies. In fact, ICTs play the role of a catalyst for the above-mentioned global and local processes, predetermine the pace of scientific and technological progress. An analysis of the achievements of a number of economically developed countries over the past few decades indicates that the state of a single national economy and the dynamics of its processes directly depend on the pace of introduction of modern means of communication and telecommunications, computer networks, data centers and other innovations into all spheres. In connection with the above, a number of global problems and local tasks arise regarding not only the adequate determination of the necessary level of development of the infocommunication infrastructure, due to the formation of new socio-economic realities, and forecasting the likely consequences of intensive use of ICT tools in various fields of activity, but also the formation of mechanisms for managing innovative development. These mechanisms should be effective and efficient in achieving the relevant management objectives. The article pays attention to a number of aspects and features of the mechanism proposed by the authors for managing the development of the infocommunication infrastructure for the formation of the digital economy and the information society as a whole. This mechanism is based on the practical application of specific methodological tools that allow monitoring the status and potential of the infocommunication infrastructure through a comprehensive assessment of the effectiveness of the introduction of ICT. The mechanism developed by the authors for managing the development of the infocommunication infrastructure will allow public authorities to specify the strategy and tactics of forming the foundations of the digital economy and the information society as a whole.
