Item Estudo da estabilidade transversal e do movimento de balanço de uma embarcação regional(Universidade do Estado do Amazonas, 2023-08-24) Almeida, Paulo Rodrigo Ramos de; Fontes, Jassiel Vladimir Hernández; Fontes, Jassiel Vladimir Hernández; Santander, Elvis Jhoarsy Osório; Campo, Eduardo Rafael Barreda del; Pérez, José Ramón HechavarríaInland navigation for longitudinal transport of cargo and passengers on Amazon rivers plays an important role in regional development, as waterway transport is often the only alternative. For this, it is common to use regional vessels, whose main characteristic is the considerable height of their superstructure. These vessels are often overcrowded with people and cargo in general. When overloaded on upper decks, the vessel's center of gravity tends to rise, which can reduce the restoration capacity during the rocking movement. If in addition to this, the interaction of external forces such as those generated by waves and gusts of wind is added, the vessel may enter into unstable conditions. As a contribution to understanding this problem, the present work presents a study of the transverse stability and rolling movement of a regional cargo and passenger transport vessel, with the purpose of evaluating the effects of different loading conditions. The vessel was modeled using computer-aided design software. On the other hand, stability and movement analyzes were carried out using methods available in the Maxsurf Stability and Motions software, respectively. In both analyzes results were compared to evaluate the effect of varying the vessel's loading condition. The intact stability of the vessel was evaluated and the results obtained were compared with regional regulations, discussing unsafe operating conditions. On the other hand, the analysis of the rocking movement was carried out under regular wave conditions, and it was found that the variation in the vessel's vertical center of gravity changes the wave condition in which the maximum angular displacement can occur. The simplified procedure proposed in the present work can be extended to characterize the stability and dynamics of other similar regional vessels.
