Abstract
A method for removing oil from a body of water including providing a matrix having a longitudinally-directed column defined by oil-absorbing and/or oil-adsorbing blankets each affixed independently of each other to a connecting strip that extends along the length of the column; deploying the matrix to a body of water to bring the column into contact with the body of water; inducing tension in the connecting strip to move blankets of the column in unison relative to the body of water; collecting oil with the first and second blankets; and removing the blankets and at least a portion of the oil collected thereby. Also, an oil spill removal system including such a matrix and in which, during matrix movement in the longitudinal direction, drag on a following blanket of a matrix column is carried by the connecting strip rather than by a preceding blanket of that column.
