INCREASING THE EFFICIENCY OF CONTAINER SHIP OPERATIONS DURING TRANSOCEANIC CROSSINGS BASED ON ADAPTIVE COURSE CORRECTION

Abstract

The analysis of the features of container ship operation during transoceanic crossings under the influence of variable hydrometeorological factors was carried out. It was established that one of the key reasons for the decrease in operational efficiency is the deviation of the vessel from the set trajectory under the influence of wind, currents and waves, which leads to increased fuel consumption, voyage duration and increased navigational risks. It was shown that traditional methods of course maintenance, which are based on periodic correction, do not provide the necessary level of adaptability in conditions of uncertainty and dynamic changes in the external environment. The feasibility of switching to proactive approaches to vessel traffic management, which are based on the integration of modern navigation systems with external data sources, is substantiated. The paper proposes a method for adaptive correction of the course of a container ship, which involves continuous analysis of the navigation situation using data from global navigation satellite systems (GNSS), electronic cartographic systems (ECDIS), as well as information from weather and oceanographic services. Particular attention is paid to the use of data from international forecasting centers, in particular ECMWF (European Centre for Medium-Range Weather Forecasts) and NOAA (National Oceanic and Atmospheric Administration), which allows taking into account forecast changes in external conditions in the process of vessel movement management. The proposed approach is supplemented by the use of methods of intelligent data analysis to identify patterns of influence of external factors on vessel deviation from the route and optimization of movement parameters. The concept of adaptive course correction has been developed, which ensures minimization of deviation from the given trajectory taking into account the energy efficiency of movement. It is shown that the implementation of adaptive course correction is especially relevant in the context of rising world fuel prices and increasing environmental requirements, in particular within emission control areas (ECA), where route optimization allows reducing operating costs and ensuring compliance with international standards. The results obtained confirm the feasibility of integrating adaptive control algorithms into modern navigation systems and navigator decision support systems, which ensures increased accuracy of vessel movement, reduced fuel consumption, improved economic performance of operation and increased navigation safety
