Ship-side ballast water treatment systems including related appratus and methods
First Claim
1. A dock-side service vehicle for treating discharged ballast water from a ship in port, said vehicle comprising:
- a water treatment processing platform accessible to a respective ship docked in port;
a housing tank positioned within said water treatment processing platform, said housing tank having at least one inlet port and one discharge port, said at least one inlet port being adapted to receive ballast water from a ballast discharge port of said respective ship by connecting a hose between the ballast discharge port on said respective ship and said at least one inlet port of said housing tank;
a filter positioned within said housing tank, said filter employed to filter particulate matter from said ballast water received from said respective ship'"'"'s ballast discharge port; and
a source of electromagnetic radiation maintained within said housing tank for irradiating said ballast water to thereby deactivate biological organisms contained therein.

Abstract
Ballast water treatment apparatus and methods for preventing foreign aquatic invasive species form entering marine ecological zones by translocation in ship'"'"'s ballast water. The apparatus includes a housing, a filter member, and UV water treatment chambers. Methods include use of a ship'"'"'s fire hydrant system or ballast water discharge port for moving ballast water from the ship'"'"'s ballast tanks into the apparatus for filtration and treatment. In-port service vessels and barges as well as dock-side service vehicles are equipped with the various treatment and filtration apparatus to provided in-port or dock-side ballast water treatment services. Related methods are also provided.

2. A method of treating discharged ballast water from a ship using an in-port service barge, said method comprising the steps of:
-
providing a ballast water treatment apparatus on board said service barge; positioning said service barge adjacent a respective ship requiring ballast water treatment; and directing ballast water from a ballast tank of said respective ship into said ballast water treatment apparatus on board said service barge to thereby treat said respective ship'"'"'s ballast water before discharging said ship'"'"'s ballast water.
-
-
3. An in-port service barge for treating discharged ballast water from a ship, said barge comprising:
-
a ballast water treatment apparatus on board said service barge, said apparatus including an inlet port, a discharge port, means for filtering ballast water, and means for directing UV energy at said ballast water; and a hoisting system for positioning a supply hose between a ballast water discharge port of the ship and said inlet port of said ballast water treatment apparatus.
