Experimental study of a recovery method of spilled oil trapped under a rubble ice field

摘要

Development of oil and natural gas deposits off Sakhalin's northern coast in the Sea of Okhotsk is currently under way. An accident involving a spill of crude oil or other effluents during the current development of the oil and natural gas deposits off the eastern coast of northern Sakhalin could be expected to affect the environment and economy of the Hokkaido's Okhotsk and Pacific coast. This paper describes a recovery method for spilled oil under a rubble ice field established through systematic experiment.
