Autonomous underwater vehicles

Definition

Autonomous underwater vehicles (AUVs) are uncrewed, self-operating robotic systems designed for underwater exploration and data collection. They are equipped with advanced sensors and navigational technology, allowing them to conduct surveys, monitor structures, and gather scientific data without human intervention. AUVs are increasingly being utilized in offshore structure monitoring due to their ability to operate in challenging environments, reducing the risk to human divers while providing high-quality data.

5 Must Know Facts For Your Next Test

1. AUVs can operate autonomously for extended periods, performing missions such as seabed mapping, environmental monitoring, and structural inspections.
2. They are often equipped with sonar systems that allow them to detect underwater features and assess the condition of marine structures.
3. The use of AUVs in offshore monitoring significantly reduces the operational costs associated with human divers and manned submersibles.
4. AUVs can be deployed in challenging conditions like deep sea or hazardous environments where human safety would be at risk.
5. Data collected by AUVs can be transmitted back to operators in real time or stored for later analysis, enhancing decision-making in offshore structure management.
