Abstract
Abstract This is a method and apparatus for containment of contaminants on fluid surfaces, particularly such as oil spillages in ocean waters, wherein the use of a floating barrier with submerged shield segments carrying high pressure jets is utilized in interconnected, segmented form.

Claim 1
Independent Claim
106 words
Means for containing a contaminant on a liquid surface comprising flotation means supporting a fluid diverting shield means connected to the flotation means by hinge means and adjustable brace means for adjusting the angular relationship between the fluid diverting shield and flotation means, and shield means extending from the flotation means below the surface of the water and having at the end opposite the flotation means an air pressure tube provided with orifices directionally directing air under pressure upward against the shield means so that it causes eddies and currents to divert the flow of contaminant away from the flotation means and into a confined area.
