Abstract: A system and method for remote inspection of a liquid filled tank or structure is disclosed. In the system, a remotely operated underwater vehicle is deployed in a liquid filled tank which includes pre-installed location identifier tags. The remotely operated underwater vehicle includes at least one camera for providing a video feed to an operator. The remotely operated underwater vehicle is piloted through tanks to be inspected, scanning tags and transmitting video and sensor data to the operator via operator's computer. The operator inspects and records observations of the video and sensor data to the system. Resulting data is recorded and reports generated.
