In view of the global dependence of oil and the imminent environmental risks of handling and transportation of oil at sea, this paper aims to reproduce the incident of leakage of oil in the buoy of Tramandaí - RS on January 26 2012, and analyze the weathering action on two different types of oil subject to environmental conditions on the day of the accident. This work used two different softwares, the ECOS oil spill model coupled to the hydrodynamic model TELEMAC-3D. Due to the history of leaks in the region of Tramandaí, this area was delimited as a study area in order to study the behavior of the oil. With the research it was possible to reproduce the hydrodynamic conditions of the day of the incident using TELEMAC-3D. The weathering processes implemented did not influence the size of the oil stain. The influence of the emulsification process proved important in the specific mass of the oil. The coefficient implemented in the model tends to stabilize the emulsification by 70% for crude oils and heavy oils, but in reality it should vary according to the specific mass of each oil. Thus, the emulsification result was the same for the two simulations, not matching what could happen under real conditions. The evaporation was well implemented in the model, varying according to each specific mass of the oil. The values ”‹”‹obtained were 4% evaporation for simulation A, 19.5% for simulation B.
