description: Theme of final qualification work: âSailing stability of vessels of complex sectionâ. This work is devoted to the study and comparison of the stability properties of barges of various sections, with variable parameters. Tasks that were solved during the study: 1. Derivation of potential energy equations for barges of various sections. 2. Conclusion of the stability region inequality for barges of various sections. 3. Construction of graphs and subsequent comparison of the results. 4. Checking the transition when changing the parameters of the pentagonal or trapezoidal profile in a rectangular or triangular problem. 5. The conclusion of the patterns and recommended parameters for the stability of ships. Analytical calculations were carried out for several barge profiles. Areas of sustainability have been implemented in MATLAB software. As a result, equations of potential energy and inequalities of stability regions for ships were obtained. Graphs were constructed for the obtained stability areas. It can be noted that in complex profiles, in particular cases, the shape, and, accordingly, the stability region coincides with simple ones, which confirms the accuracy of the calculations. When designing ships, selecting profile parameters, it is recommended not to leave the stability areas given in this paper. The results can be applied in the design of ship or barge profiles.
