海上运输和石油开采活动的增长可能会增加石油泄漏的风险。因此，需要制定防止或减轻影响的计划和行动，将石油造成的影响降至最低。然而，世界各地用于支持应急计划的工具没有被纳入，从而导致在确定优先领域方面失败。这项研究旨在通过结合环境对石油的敏感性信息和溢油数值模拟的结果来制定环境对石油的脆弱性指数(IEVO)。为实现这一点，设计了一个关于亚热带沿海地区漏油情况的案例研究，并计算了IEVO并将其显示在地图上，以便更容易地显示关于该地区脆弱性的信息。夏季，可能受石油影响的海岸线延伸约150公里，大部分海岸线呈现中等至高度脆弱性。冬季，230公里的海岸线将受到影响，其中75%被归类为中等至高度脆弱性。因此，IEVO地图可以更快速、更清晰地解释地图区域的脆弱性，便于规划进程和应对漏油事件的行动。
The growth of maritime transport and oil exploitation activities may increase the risk of oil spills. Thus, plans and actions to prevent or mitigate impacts are needed to minimize the effects caused by oil. However, tools used worldwide to support contingency plans have not been integrated, thus leading to failure in establishing priority areas. This investigation aimed to develop indices of environmental vulnerability to oil (IEVO), by combining information about environmental sensibility to oil and results of numerical modeling of spilled oil. To achieve that, a case study concerning to oil spills scenarios in a subtropical coastal area was designed, and IEVOs were calculated and presented in maps, in order to make the information about the areas’ vulnerability more easily visualized. For summer, the extension of coastline potentially affected by oil was approximately 150 km, and most of the coastline presented medium to high vulnerability. For winter, 230 km coastline would be affected, from which 75% were classified as medium to high vulnerability. Thus, IEVO maps allowed a rapid and clearer interpretation of the vulnerability of the mapped region, facilitating the planning process and the actions in response to an oil spill.
