Abstract
An oil spill recovery system for removal of oil spill contaminants from the surface of a body of water has a suction blanket which can be deployed by a host vessel, there being a plurality of air pressure lines through the blanket with suction ports to induce the flow of water and any oil spill in communication with the ports through the conduits into a common collection chamber, and the contaminants can then be exhausted or removed from the collection chamber as necessary and separately collected.
Claims14
In an oil spill recovery system for collecting oil spill contaminants from the surface of a body of water wherein a host vessel is provided with a source of air under pressure, the combination therewith comprising:
- a buoyant suction blanket in the form of a flexible, elongated sheet member having opposed upper and lower surface portions and a plurality of conduits extending through said blanket between said upper and lower surface portions, and suction ports at spaced intervals along said conduits for extension behind said vessel between an associated one of said conduits and at least one of said upper and lower surface portions, said blanket having a continuous series of depressions in closely spaced relation to one another formed in at least one of said upper and lower surface portion and said ports communicating with said depressions in said one surface portion;
- means for towing said blanket behind said vessel;
- air intake and exhaust means cooperating with said conduits to induce the flow of water and any oil spill accumulating on said one surface portion through said ports into said conduits as said blanket is being towed;
- and
- means for collecting said water and contaminants from said conduits.
In an oil spill recovery system for collecting oil spill contaminants from the surface of a body of water wherein a towing apparatus is provided with a host vessel, a source of air under pressure and air intake and exhaust means, the combination therewith comprising:
- a buoyant suction blanket in the form of an elongated flexible sheet member having opposed parallel surface portions and a plurality of conduits extending through said blanket parallel to said surface portions, and suction ports at spaced intervals along said conduits and normal to said conduits for extension through one of said surface portions;
- said air intake and exhaust means cooperating with said conduits to induce by venturi effect the flow of water and any oil spill in communication with said ports into said conduits as said blanket is being towed;
- a collection chamber for collecting said water and contaminants from said conduits;
- and
- steering means associated with said blanket for controlling the direction of movement of said blanket when deployed by said host vessel, said steering means including steering jets in communication with said air pressure source, valve means for each said jet, said steering jets disposed along opposite sides of said blanket, and remote control means on said vessel for independently controlling opening and closing of said valve means for each said jet.
