USE OF FLOATING DEFLECTORS FOR OIL SPILL CONTROL IN FAST FLOWING WATERS

The principle employed is to deflect the oil from where the spill takes place into a portion of the river where the currents are slower and the oil can be collected by conventional means. This is achieved by a system of floating deflectors comprising a series of hydrofoils mounted on a horizontal frame anchored to the shore. The interaction of the hydrodynamic forces on the hydrofoils creates an equilibrium state at which the system floats at an angle with the main current. At this equilibrium state the deflectors induce a controlled spiral circulation which deflects the surface currents and spilled oil in a selected direction. Experiments were conducted in a straight flume to study the characteristics of hydrofoils used as deflectors. In the Majority of cases without deflectors only about 40%-50% of the oil would go in the north arm of the river. With the deflectors, the number increased to about 90%.
