| Abstract | |
This study examines the accidents registered in Tietê-Paraná waterway, identifying the most important ones and respective causes, with the purpose of proposing means of reducing the probability of occurrence of such accidents. The bibliography survey carried out, although it includes a relatively small number of studies, contributes to a better understanding of the most important aspects of the accidents occurred in waterway transportation. From the analysis of Tietê-Paraná waterway, with the identification of its critical points for navigation, the employed vessels and the available workmanship, it is possible to sketch the scenary for a better comprehension of the main accidents and their causes. The accomplished statistical analysis, using the data available at the Barra Bonita Fluvial Command, lead to the following conclusions: the main problem are the collisions involving pushtows, representing 48,8 % of the total registered accidents; 60 % of the total registered collisions corresponds to collisions against bridges pillars. With respect to the main identified accident, it is presented a discussion about the methodology used for the determination of brigde span openings, showing that it does not fit to local navigation conditions. Procedures regarding to minimize the probability of collisions against bridges pillars and reduce their effects are mentioned. The conclusion is that only with more detailed studies, using both maneuvring simulation models and experimental trials with scale models, it will be possible to reach a methodology for the determination of bridge span openings which assures safer conditions for navigation along the Tietê-Paraná.
