大型船舶在运输石油及其衍生物方面效率很高。但是，在发生事故时，它们可能会导致溢出。这项研究的目的是模拟在与亚马逊港口和大西洋相连的海上航线上航行的船舶可能发生事故的情况下的石油扩散过程。导航路线以交通数据为基础，以确定风险区域，并将其与环境（石油）敏感性指数数据和羽流扩散数值模拟结果进行比较。这三种方法相互结合，以评估羽流对沿海生物区系和人口的潜在环境影响。情景模拟结果表明，雨季是烟羽扩散的最关键时期。但是，根据排放点的不同，羽流往往保持靠近海岸，在72小时内延伸到132公里，影响生物多样性，保护区和城市地区的供水系统。
Large ships are efficient in transporting oil and its derivatives. However, they can cause spills in the event of accidents. The aim of the study is to simulate oil dispersion processes in scenarios of likely accidents with ships traveling on sea routes interconnected with Amazonian ports and with the Atlantic Ocean. Navigation routes were based on traffic data to identify risk areas, as well as to compare them to data from the environmental (oil) sensitivity index and to results of numerical simulations of plumes dispersion. These three approaches were integrated to each other in order to assess potential environmental impacts of plumes on coastal biota and human populations. Scenarios results have indicated that the rainy season is the most critical period for plumes dispersion. But, depending on the emission point, plumes tend to remain close to the coast, extend up to 132 km within 72 h, affecting the biodiversity, protected areas and water supply systems from the urban areas.
