Methodology for justifying thrust on mooring lines of a small fishing vessel

The relevance of the study is stipulated by the need to obtain reliable information on the mooring pull for fishing vessels, as well as for transport vessels involved in towing fishing boats both in the coastal zone and inland waters of the Russian Federation. The current state of the small fishing fleet is characterized by the presence of obsolete vessels that require constant repair and modernization. One of the key characteristics that determine the efficiency of a fishing vessel is its mooring pull, which affects the maneuverability and safety of the vessel in confined spaces. However, it should be noted that it is not always possible to accurately determine the mooring pull of a small vessel based solely on mathematical dependencies. This is due to the fact that the mathematical models include empirical coefficients obtained not for the entire range of characteristics of various types of fishing vessels, their engines and types of propellers. This circumstance significantly limits the possibilities of using the mathematical apparatus to justify the traction on the mooring lines of a small fishing vessel. The article presents approximate dependencies of the traction on the mooring lines for a small fishing vessel, which allows improving the accuracy of calculations and increasing the reliability of fleet operation. This technique can serve as a basis for further research in the field of optimizing the characteristics of the small fishing fleet and its renewal, which, in turn, will contribute to improving the overall efficiency of fisheries in the country.
