Abstract
An autonomous underwater vehicle (AUV) for recording seismic signals during a marine seismic survey. The AUV includes a body having a flush shape; an intake water element located on the body and configured to take in water; at least one propulsion nozzle located on the body and configured to eject the water from the intake water element for actuating the AUV; at least one guidance nozzle located on the body and configured to eject water to change a traveling direction of the AUV; and a seismic payload located on the body of the AUV and configured to record seismic signals.
Claims23
An autonomous underwater vehicle (AUV) for recording seismic signals during a marine seismic survey, the AUV comprising:
- a body that is configured to be selectively steered to land on the bottom of the ocean;
- wherein the body has a front end and a tail end, wherein a cross-sectional profile of the body is substantially uniform from the front end to the tail end, and wherein the front end and tail end have substantially similar shapes, and
- an intake water element located on the body and configured to take in water when deployed underwater;
- at least one propulsion nozzle located at the tail end of the body and configured to eject the water taken from the intake water element for propelling the AUV;
- at least one guidance nozzle located on the body and configured to eject water to change a travelling direction of the AUV;
- and
- a seismic payload located on the body of the AUV and arranged to record seismic signals while the AUV is resting on the bottom of the ocean.
