Unmanned and autonomous survey vessels

Unmanned surface vehicles (USVs; also known as unmanned surface vessels or in some cases autonomous surface vehicles (ASVs), uncrewed surface vessels, or colloquially, drone ships) are boats or ships that operate on the surface of the water without a crew. USVs operate with various levels of autonomy, from simple remote control, to autonomous COLREGs compliant navigation. An autonomous survey vessel is an unmanned vessel fitted with survey equipment and capable of operating without human supervision while performing survey work, either uploading the data in real time, or at pre-programmed stages, or on a remote command.

Autonomous underwater vehicle An autonomous underwater vehicle (AUV) is a robot that travels underwater without requiring input from an operator. AUVs constitute part of a larger group of undersea systems known as unmanned underwater vehicles, a classification that includ ...

s set up for survey work are a subclass of autonomous survey vessels that operate underwater. unmanned survey vessels are usually relatively small and therefore economical to acquire and operate, and can be sent to areas too hazardous for a larger or crewed vessel, as well as for extensive and time-consuming but routine surveys. USVs are valuable in oceanography, as they are more capable than moored or drifting weather buoys, but far cheaper than the equivalent
