“…Scientific and technological assessment of stability, mechanical systems, and maneuvering (steering and control) issues are also lacking. An example of scientific application would be the study of the behavior of vessels subjected to severe beam wind [80], which would require advanced simulation methods and experimental data for validating their results, as shown by [55,81,82]. Simulation methods based in Computational Fluid Dynamics (CFD) should be employed to analyze accidents related to flooding, fire and explosions, and oil spills, as demonstrated by Zhang et al [83], Xie et al [84], and Tkalich [85], respectively.…”

The Brazilian Amazon is part of one of the largest river systems in the world, in which the transport of cargo and passengers is commonplace. However, several accidents still occur to passenger ships, causing fatalities. Transportation occurs commonly in remote regions, where there are transport inequalities, and emergency assistance is hard to find. This can affect sustainability in communities with considerable levels of economic and social vulnerability. More information is needed about accidents involving inland transport in the Amazon, to identify the threats to ships and propose strategies for accident prevention. This paper addresses the main problems that long-distance passenger ships face in the Brazilian Amazon, presenting an integrated framework towards accident prevention. First, the present situation is characterized in terms of ship description, spatial distribution, and regulations that are applicable. Next, possible causes of passenger ship accidents are discussed, including topics of concern that should be considered in the Amazon waterways. Finally, measures to help minimize passenger ship accidents are proposed, and the social relevance is discussed. It was found that accidents in the Amazon are due to a combination of human and environmental factors. Stakeholders should strengthen the technical and legal training of ship operators. The use of new technologies for navigational aid and necessary maintenance of ships is suggested. Marine accident prevention initiatives should consider local conditions, such as environmental preservation, cultural respect, and difficulties related to navigation through the complex riverine system of the Amazon region.

“…In CFD, the computed domain has affected CFD results, therefore, the same must be designed following the user guide for applied CFD in ship hydrodynamics or CFD manual published by the ITTC or CFD manufacturer [1]. Moreover, the researcher's experiment is of very importance in using CFD to solve the same problems on aerodynamic performances [9,10,[13][14][15][16]. Figure 2 shows the limited dimension of the computed domain.…”

“…All meshes have been generated with the quality following the user guide for applied CFD in ship hydrodynamics [1,14]. In this research, conditional boundary has been proposed appropriately based on the author's experience in using CFD and the available references [1,9,11,[13][14][15]. For computation, the turbulent viscous model k- has been used, the velocity inlet is set up for the inlet, the pressure outlet is set up for the outlet and the non-slip wall is used for the model [14,17].…”

In this paper, a commercial CFD code, ANSYS-Fluent has been used to investigate the effect of mesh number generated in the computed domain on the CFD aerodynamic performances of a container ship. A full-scale model of the 1200TEU container ship has been chosen as a reference model in the computation. Five different mesh numbers for the same dimension domain have been used and the CFD aerodynamic performances of the above water surface hull of the ship have been shown. The obtained CFD results show a remarkable effect of mesh number on aerodynamic performances of the ship and the mesh convergence has been found. The study is an evidence to prove that the mesh number has affected the CFD results in general and the accuracy of the CFD aerodynamic performances in particular.
