OIL RECOVERY METHOD AND DEVICE THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide an oil recovery method and a device therefor capable of being built in and mounted on a small ship, and using a light and small oil recovery device which can continuously and effectively recover floating oil of high viscosity and super high viscosity floating on the water surface. SOLUTION: A flow passage having an opening for the admission of floating oil O1 at a front side and moving close to a broadside at a back side to reduce to a lifting and recovering part, is formed by an oil fence 33 on the broadside of a working ship S. A net conveyer detachably attached to the broadside of the working ship S is arranged by inclining to the lifting and recovering part in such a way as to submerge a tip end thereof in water. Floating oil on a water surface and an oil mass O1 is guided from the opening and collected into the lifting and recovering part as the working ship S moves forward. The collected oil and the oil mass O1 is scooped up by the tip end portion with the net conveyer sunk under the water surface W, and depositing oil O2 is recovered by an oil scraping device 5.
