Abstract
Currently available hull thickness sensors use ultrasonics and provide coverage of a single point on the hull. The sensor must then be moved over the hull while the thickness readings are monitored to detect thin areas of hull plate. These systems generally contain array type sensors; however, they are not suitable for underwater applications because of the electronics and the precision involved. FBS is proposing to develop a novel guided wave phased array transducer for large area inspection from a single probe position. The newly designed sensor could be used by divers or integrated into an underwater remotely piloted vehicle to interrogate large sections of the hull for corrosion.
