Abstract

The system comprises a flexible line provided with means for collecting products scattered at the water bottom by circulating the flexible line in contact with these products. On the rising portion of the path followed by the flexible line, the collecting means are passed through a tubular casing for simultaneously protecting the surrounding water against pollution from products released, while hoisting the products to the surface.
