Abstract
The removing techniques for oil spill in the marine environment are summarized from a viewpoint of physical and chemical principle in this review. The recovery systems and the enhancement of biodegradation are recommended to remove oil spill in offshore area under the stormy weather, because there are left rooms to estimate the effect of chemical agents and dispersions on the marin environment. The recommended recovery systems are the suction pump to remove the weathered oil-water emulsions and oil debris, and the techniques to remove oil leaked from the tankers sinking in the deep sea. Large-scale ships are also recommended to be constructed for removing a large scale of oil spill under the stormy marine environment.
