Development of Recovery Methods for Spilled Oil under Ice Floes

Development of oil and natural gas deposits off Sakhalin's northern coast on the Sea of Okhotsk are currently under way. Should an accident involving a spill of crude oil or other effluents occur during the development of the oil and natural gas deposits that is currently under way off the eastern coast of northern Sakhalin, it can be expected to have an impact on the environment and economy of the Hokkaido's Okhotsk Sea and Pacific Ocean coast. This paper describes the recovery method for spilled oil under ice floes through the systematic experiments.
