Abstract
An acoustic data acquisition system for shipboard use is disclosed that allows for underwater acoustic data measurements at preselected submerged marine structural coordinates using a free swimming, quiet dynamically positionable remotely operated vehicle (ROV). Moreover, the disclosure provides a method of performing acoustic data acquisition with an ROV by first inputting the marine structural features by use of a computer aided design subsystem, determining the required trajectory path and hovering coordinates for data measurements, next, establishing the acoustic telemetry system for the remotely operated vehicle's control system to operate within and make an absolute positional fix to the marine structure's coordinates then, establish the ambient acoustic conditions of the worksite. The system is monitored and controlled from a computer based system. The system includes an ROV subsystem that operates in conjunction with a computer based long baseline underwater telemetry and positioning control subsystem, an acoustic transducer array attached to the ROV and a real time data-coordinate storage subsystem. A particular type of transducer suitable for use with this vehicle is a pa…
