ABSTRACT:
This invention relates to a novel apparatus for cleaning and salvaging oil spills in marine environments. The invention is directed to a dual purpose vessel adapted for use in sand dredging and oil spill clean-up comprising: (a) a hull; (b) at least two pump suction tubes mounted to the exterior of the hull, the suction tube inlets being located below the water line of the hull, and being rotatably connected to the hull; (c) a draghead which is adapted to ride in part above the water level attached at the end of each suction tube opposite the suction tube inlet connection; and (d) a buoyancy compensator cooperating with the draghead to ensure that at least part of the draghead rides above the water level at all times.
