Abstract:
An autonomous underwater vehicle (AUV) is configured to record seismic signals during a marine seismic survey. The AUV includes a body having a base (B) and first and second sides (A, C), the body having a head part and a tail part; a propulsion system for guiding the AUV to a final target on the ocean bottom; jet pumps connected to corresponding nozzles on the first and second sides (A, C); a control device connected to the jet pumps; and a seismic sensor configured to record seismic signals. The jet pumps are actuated by the control device in a given sequence so that the base (B) penetrates into the ocean bottom.
