ON THE CREATION OF A MATHEMATICAL MODEL FOR THE MOVEMENT OF LARGE-FORMAT CONTAINER SHIP IN SHALLOW WATER RESTRICTED AREAS UNDER COMPLEX NAVIGATION, HYDROGRAPHIC, AND HYDROMETEOROLOGICAL CONDITIONS OF NAVIGATION

Abstract

The article discusses the problem of ensuring navigational safety for large container ships under complex navigation, hydrographic, and hydrometeorological conditions. The authors point out that the implementation of Electronic Chart and Navigation Information Systems (ECDIS) and Global Navigation Satellite Systems (GNSS) has not led to a significant reduction in ship accidents, especially during shallow water operations. Objective factors that significantly complicate the safe navigation of large vessels are considered, including limitations in the operation of the main propulsion plant and navigational characteristics. The presence of a high windage also complicates ship course-keeping. Vessel design features, such as a long stopping distance and the presence of only one propeller shaft, also have a negative impact on their maneuverability and safety. It is noted that GNSS capabilities are underutilized for trajectory correction and real-time navigation tasks. The dimensions of channels and fairways do not always correspond to the sizes of modern vessels, leading to constraints on the maneuverability and the risk of grounding during navigation.

The article proposes an approach to evaluating the indicators of navigational safety for large container ships by developing a mathematical model that would improve their safety in complex conditions. The authors also mention the possibility of using artificial intelligence to automate ship control processes in hazardous situations. The presented mathematical model of the movement of large container ships requires further development and further research and development to improve the safety of navigation for such vessels.
