Agenda Session

Geophysical surveys have operational complexity because they typically require the handling of one or more tow bodies to collect data using a sidescan sonar and magnetometer. Automating the tow handling so that these sensors can be operated remotely through an Uncrewed Surface Vessel (USV) presents operational challenges, and opportunities for more efficient seabed data collection. Chance Maritime Technologies developed a series of technologies, including a remotely operable launch and recovery system, that works with a new USV hullform optimized for towing operations. The use of this system was demonstrated in archaeological surveys offshore, for weekslong continuous operations without human intervention. Surveys were conducted with sidescan, magnetometer, sub-bottom profiler, and sound velocity profiler systems. The novel hull form has also been shown to be usable for the launch and recovery of Remote Operated Vehicles (ROV). This talk will dive into how geophysical, archaeological, and inspection surveys can be completed more efficiently with a high-power long-endurance USV.
