Metodologia para caracterizar a geometria do casco e o comportamento hidrodinâmico de uma embarcação regional amazônica do tipo expresso

Abstract

The current reality of river transport of cargo and passengers in the Amazon region is affected by problems linked to the lack of infrastructure and safety in navigation, which contributes to the increasing number of accidents and victims in such a transport modality. The university can work to develop technical-scientific procedures that allow to understand the behavior of ships and find options to solve these challenges. Characterizing the hydrodynamics of vessels, including the study of their hull resistance and response in waves, can contribute to the understanding of their behavior in various operating conditions. This work aims to instruct the computational modeling procedure of the hull, estimation of the ship resistance and dynamic behavior of a longitudinal passenger transport vessel that is typical of the Amazon region: an express-type ship. The main objective is to guide the three-dimensional hull design procedure from the body plan and use this geometry to carry out parametric studies of ship resistance and response in regular waves, using software for practical use. Therefore, this work involves the application of two computational tools, the Rhinoceros software for three-dimensional hull design and the Maxsurf software, in its Resistance and Motions modules, for ship resistance and motion calculations, respectively. The results obtained through the software allowed us to conclude important observations, which can be subsequently evaluated and compared with the performance of experimental tests. It is hoped that this methodology can be extended to characterize the hydrodynamic behavior of other regional vessels.
