In this study, we carry out environmental and economic loss analyses of the oil discharge from the shipwreck Jeh Hun. By performing 500 simulations of hypothetical oil spill cases, we obtain the minimum and worst damage cases. In the minimum damage case, there is just marine pollution without coastal pollution or aquaculture farm pollution. On the other hand, in the worst damage case, there is serious marine pollution, coastal pollution, and aquaculture pollution. The main purpose of the environmental and economic loss analyses is to support salvage planning for the shipwreck, because we have to consider the oil discharge from the shipwreck during oil removal and salvage. The results of this study show that the best salvage time is early morning in winter, when the northwest wind and maximum flood tide are dominant resulting in the spilt oil going forward into the open sea without coastal pollution and aquaculture pollution.
在这项研究中，我们对 Jeh Hun 号沉船的溢油进行了环境和经济损失分析。通过对 500 个假设溢油案例进行模拟，我们得到了最小和最坏损害情况。在最小损害情况下，只有海洋污染，没有沿海污染或水产养殖污染。另一方面，在最坏损害情况下，存在严重的海洋污染、沿海污染和水产养殖污染。环境和经济损失分析的主要目的是支持沉船的打捞计划，因为我们在清除和打捞沉船时必须考虑到沉船的溢油情况。本研究的结果表明，最佳的打捞时间是冬季的清晨，此时西北风及最大涨潮主导，导致溢油向前进入开阔海域，没有沿海污染和水产养殖污染。
