ABSTRACT:
A method for disposal of material on subaqueous ground substantially without said material coming into contact with the surrounding water is disclosed. The method comprises positioning a ship carrying said material above a selected site for disposal, transferring said material to a container or vehicle adapted to transport said material to the subaqueous ground, conveying said material to a level at, or close to, said subaqueous ground and depositing said material from said container onto said subaqueous ground. The method can be used to deposit two materials one over the other--i.e. by capping--which is valuable where the first material is a contaiminated waste product, and the second is an uncontaminated waste product. A ship for use in the method of the invention is also disclosed.
