In the Mediterranean Sea unique environmental characteristics and sensitive assets coexist with intense maritime traffic that is represented by frequent daily passages of vessels along the main waterways. In order to assess the risk of oil stranding in case of at-sea emergencies and provide key products for environmental agencies or policymakers preparedness, a geographically relocatable, operational numerical system is implemented and tested. The system relies on the application of oceanographic and particle tracking models and is able to provide, on a high-resolution and unstructured computational grid, a 3-days forecast of those variables known as the main drivers of oil slicks at sea. The risk of potential oil stranding is computed through a combination of anthropogenic hazard and shoreline vulnerability. The sources of hazard vary on time and space in relation to local maritime vessel traffic. The shoreline vulnerability is based on the current knowledge of slope, main grain size, geology of rocks, and occurrence of manmade structures at coast. The operational system is enriched by a web graphical user interface and includes automatic and on-demand working modes. Its functionality is demonstrated in the Strait of Bonifacio (western Mediterranean Sea), area with a high potential risk of oil stranding due to an intense maritime traffic. Risk assessment is hence computed for a test year, the 2018. Critical values of risk are found in correspondence of long stretches of littoral while many of them are currently characterized by a low anthropogenic pressure. The results emphasize the geomorphological features of the shorelines as reducing or amplifying factors to any potential impact of oil stranding at coast.

在地中海，独特的环境特征和敏感资产与繁忙的海上交通并存，其特征是船只每天沿着主要水道频繁航行。为了评估在海上紧急情况下搁浅的风险并为环境机构或决策者的准备工作提供关键产品，实施并测试了可地理定位的可操作数值系统。该系统依赖于海洋学和粒子跟踪模型的应用，并且能够在高分辨率和非结构化的计算网格上提供为期三天的那些变量预报，这些变量被称为海上浮油的主要驱动力。潜在的石油搁浅风险是通过人为危害和海岸线脆弱性相结合来计算的。危险的来源在时间和空间上与当地海​​上船只运输有关。海岸线脆弱性基于当前的坡度，主要晶粒尺寸，岩石地质学以及沿海人造结构的发生等知识。Web图形用户界面丰富了该操作系统，并包括自动和按需工作模式。在波尼法西奥海峡（地中海西部）中证明了其功能，由于海上交通繁忙，该地区极有可能发生石油搁浅的风险。因此，针对一个测试年（即2018年）计算风险评估。发现风险的临界值对应于沿岸的长距离延伸，而其中许多当前的特征是人为压力低。
