In this dissertation an analysis is performed on the operational behavior of river barges
convoys in navigation regions with presence of waves, winds and currents. A study is carried
out to determine the applicant forces present in the mooring elements and in the contact points
between barges in flotillas when they are sailing in dangerous navigation conditions. A
theoretical study is carried out, identifying the main response movements of floating bodies. In
this case, a model is developed using the ANSYS AQWA 17 software to identify the stress
levels from impacts between barges that make up the formations, as well as the degree and
behavior of the tensile stresses present in the mooring ropes over time. In addition, a practical
study is used as a comparative model of data, being very important for the validation of the
results achieved by the computational model. In this way, the proposed scenario within the
computational program describes environmental characteristics to describe the navigation
problem in a clear way. At the end of this work the levels of effort captured within the
computational model are presented, being divided into two models of fluvial flotillas, a convoy
with barges for soybean transportation, and another with barges for the transport of iron ore,
being discriminated the locations of the higher levels of effort. It is important to note the
pioneering role of this work in relation to the problems perceived within the area of operational
safety of fluvial flotillas, using Finite Element tools as the main evaluation tool. |
