By the accidents, the oil is spilled frequently at sea. Some systems for the removal of the spilled oil are developed. There are two main methods to withdraw the spilled oil. One is the method by a suction pump. The collected oil by the method contains much water. The other is the method by making the oil adhere to a plate. The collected oil by this method contains little water and this is useful in the case of the thin oil layer. In the case to withdraw the oil by rotating discs, or belts, authors tried to analyze about oil thickness on the plate and to get the optimum velocity for rotating discs to withdraw spilled oil. The thickness of the oil film on the plate is regard to depend on the velocity of plate, viscosity of the oil and gravity. Two cases were studied. The one is one kind liquid layer case. Another is that the liquid consists of two kinds, e.g. the oil slick case on the water surface. The optimum rotating velocity and the quantity of the removed oil are gotten theoretically and they agree to the results of the experiment well.
