摘要

Along with side scan and bathymetry, sub-bottom profiling is a key technology for subsea engineering and geophysical investigations, and is a core requirement for many oil and gas, and offshore renewable energy surveys. In the last decade, huge progress in small AUV technology has led to rapid uptake in the offshore survey industry. Advances in power, propulsion, positioning and control have resulted in low-logistics, man-portable vehicles that can carry compact instrumentation payloads and collect survey-quality sonar data, with mission duration and depth capabilities suitable for general survey work. The data quality from the latest generation of payload sensors satisfies engineering inspection and geophysics requirements, where previously a boat-mount or ROV-mounted sonar was needed. In addition, the small AUV has the unique ability to access restricted areas and acquire high-resolution data from deeper water.
