Battelle and its partners are working to make American ports safe from terrorists and international drug cartels by creating an underwater sensor array that scans all ships as they enter United States harbors.
Battelle is teamed with the Naval Undersea Warfare Center (NUWC) and EdgeTech Marine in a mutually funded and in-kind cooperative research and development program called Harbor Shield. The Harbor Shield system uses powerful imaging technology to map the underwater hulls of ships as they enter harbors, scanning their bellies to detect weapons of mass destruction, mines, bundles of illegal drugs, and any other irregularities. It can detect the exact location on the hull of any abnormality as small as a square foot.
Simultaneously, topside sensors will determine the ship's exact location in relation to the underwater sensors. The combined data will be used to create a "hullprint" that will be stored in a global network. After being scanned once and entered into the hullprint database, ships will be cross-referenced and their hullprints updated each time they sail into another American port. Eventually, Harbor Shield will contain a database of all ships that have entered American ports.
"Harbor Shield is a high-end solution for maritime investigative deficiencies," said Lynn Faulkner, Program Manager for Battelle's Equipment Development Group. "It also is a fine example of dovetailed cooperation between government and private industry to solve a critical national security problem."
The concept of the Harbor Shield technology was proven this year in Narragansett Bay, Rhode Island. A full-scale, baseline demonstration of the technology is planned for mid 2009 in the same estuary. As Harbor Shield matures, enhancements will be incorporated, such as improved and automated imaging (so humans won't have to stare at a screen of every rendering of every hull) and a larger database. Eventually, Harbor Shield should be capable of scanning entire harbors for every boat and swimmer. It also could benchmark ship hull maintenance; enhance hull inspections for marine growth, damage, corrosion, and paint thickness; and even determine what liquids are stored within the hull.
Currently there is no system to inspect the estimated 50,000 worldwide freighter ships as they enter American ports. Without Harbor Shield, ships' underwater hulls can only be inspected by divers. If a ship is deemed to require investigation, it must anchor and shut down all its engines and intakes to prevent diver injury. Divers must then hand search the hull by feeling their way along in murky water, often missing large sections of the surface. The practice is time consuming, costly, and largely ineffective. Harbor Shield represents a quantum leap forward and could save time, money, and lives. It will also enable U.S. authorities to scan every ship that enters port instead of a very small percentage of them.
