The fate and behavior of the Sanchi oil spill during January-February 2018 was simulated by coupling an oil spill model and satellite observations with meteo-oceanographic forcing. Extensive validation tests were performed for winds, currents, surface slick, stranded oil and oil fate. A series of hindcast experiments was designed to take into account the uncertainties in oil amount, environmental forcing and model parameters. The simulations confirmed that the stable large-scale Kuroshio acted as the primary driving force. Most oil followed the Kuroshio's large-meander path, rapidly passing through the East China Sea to the waters south of Japan. The wind, appearing as the secondary transport factor, did not change the path of this large-scale current, but did contribute to the drift of surface oil. The different fates for heavy fuel oil and condensate in the accident were also compared quantitatively and discussed in this study.
采用溢油模型和卫星观测与气象海洋强迫相结合的方法，模拟了 2018 年 1 月至 2 月期间桑吉号油轮溢油的运移和归宿。对风、流、海面溢油、漂移油和油的归宿进行了广泛的验证测试。设计了一系列的回溯实验，以考虑到油量、环境强迫和模型参数的不确定性。模拟结果证实，稳定的大规模黑潮是主要驱动力。大部分油污随黑潮大弯曲路径迅速穿过东海，到达日本以南水域。风作为二次输运因素，并没有改变这条大规模海流的路径，但确实促进了海面油污的漂移。本研究还对事故中重燃料油和凝析油的不同归宿进行了定量比较和讨论。
