METHOD FOR RECOVERY OF OIL SPILLED ON SEA SURFACE AND OIL RECOVERY VESSEL

摘要

Provided is an oil recovery method which can be readily employed even in the case of accidental marine oil spill over large areas. A recovery vessel (1) with a plurality of intakes (23) provided through the shell plating at a forward portion on both the broadsides of the hull is navigated across a sea surface contaminated with oil, the intakes (23) being shaped in an elongated slit in the fore and aft direction and arranged side by side in a line. The draft of the hull is controlled to maintain the intakes (23) at the level of the sea surface during recovery operations. The oil water mixture on the sea surface is drawn into the vessel through the intakes (23) of the recovery vessel (1) and then separated by specific gravity into oil and seawater in an oil water mixture reservoir tank (17).
