Abstract

The technique of ballasting the damaged vessel when landing on the ground and preventing the ejection of waves and wind forces aground is being implemented. A mathematical model of the positioning of a vessel in contact with the bottom of the water area by taking and moving liquid ballast along the hull is considered. The relevance of the study is that the quantitative regulation of ballasting will overcome the shortcomings and more successfully use this method in the implementation of rescue operations. This fact is achieved by creating and analyzing a mathematical model of an emergency vessel, which is subject to ballasting and at the same time drifts under the influence of wind and waves in shallow water and with a high probability of throwing the vessel ashore.  The adopted hydrodynamic model of the process of throwing a ship aground provides an appropriate schematization of physical phenomena. The force of wind and waves on a vessel drifting in a shallow area leads to periodic hull impacts on the ground.  Calculated dependences and nomograms are proposed for determining the rational amount of ballast, its positioning and movement. Recommendations are given for preventing the drift of a vessel during emergency contact with the ground. Recommendations are given for preventing the drift of a vessel during emergency contact with the ground. Тhe proposed graphical dependencies will increase the efficiency of preventing the drift of the damaged vessel and contribute to the preparation of the ship’s crew for worsening weather conditions, reducing the degree of damage and the volume of rescue operations. The research results are used in the educational process in training specialists in specialty 135 "Shipbuilding" during the study of the theory of the ship and ship repair items.
