Recovery modeling and countermeasures for oil spilled at sea have been extensively researched, but research remains insufficient on recovery potential estimation methods. It is required to access the mechanical recovery potential by considering the relationship between oil behavior, environmental conditions, and the performance of clean-up activities. Two response-planning models were developed in this study. One is a spatially uniform recovery model for estimating recovery potential that reflects weathering, oil properties, and equipment efficiency. The other is a spatially nonuniform recovery model that considers not only the above characteristics but also local thickness reduction by skimming. A comparison between the two models and an analysis of their effects on response was carried out through the calculation using an accident scenario. It is possible to analyze the effect of the thin slicks, natural dissipation, and the quantification of deployable skimming systems with the spatially nonuniform recovery model. Finally, we analyzed interrelationships among residual oil volume on the sea, response time, and the number of skimming systems.

考虑空间厚度分布的海上溢油机械采收潜力估算

海上溢油的采油模型和对策已经得到了广泛的研究，但是对采油潜力的估算方法仍然缺乏研究。需要通过考虑油的行为，环境条件和清理活动的性能之间的关系来获得机械采收潜力。在这项研究中开发了两个响应计划模型。一种是空间均匀的采收率模型，用于估算反映出风化，油性和设备效率的采收潜力。另一个是空间上不均匀的恢复模型，该模型不仅考虑了上述特征，而且还考虑了通过撇取减少局部厚度的问题。通过使用事故场景进行计算，对两个模型进行了比较，并分析了它们对响应的影响。可以使用空间非均匀恢复模型来分析薄浮油，自然耗散以及可部署撇油系统的量化效果。最后，我们分析了海上残留油量，响应时间和撇油系统数量之间的相互关系。
