Abstract:

We designed, fabricated, and tested a new autonomous underwater vehicle system to carry out inspections of large ship hulls. The vehicle employs hull-relative navigation, so that operations can be performed without any absolute positioning data, and in poor acoustic environments. The primary payload sensor is an imaging sonar, whose data stream can be sent via fiber optic tether to a ground station for viewing. The system has been successtully demonstrated surveys and target detections on three vessels in Quincy, MA, San Diego, CA, and La Spezia, Italy. Work was performed in coordination with Bluefin Robotics Corporation, under separate ONR funding.
