Oil slick drift characteristics on the water surface by wind under swell conditions were experimentally studied. In the experiments, drift velocity of the oil slick was measured using a wind wave tunnel tank. It was confirmed that without swell, the drift velocity is nearly 0.03 times faster than the wind velocity 10m high above the sea surface. In the case that the swell exists and propagates to the same direction of the wind, the drift velocity by the wind was found to become smaller as the steepness of the swell increases. This observation agrees with other researchers such as Reisbig et al. (1973) in spite of different experimental tank size. The result of this study will be instructive for precise prediction of the oil slick at oil spill incidents.
