Abstract

Method and vessel for performing marine acoustic survey of a subsurface. The vessel includes a launching module configured to deploy an autonomous underwater vehicle (AUV) underwater; a recovery module configured to recover the AUV; a homing device mounted on the recovery module and configured to guide the AUV to the recovery module; and a management module connecting the launching module to the recovery module and configured to transport the AUV.

First claim

What is claimed is:

1. A vessel for performing a marine acoustic survey of a subsurface, the vessel comprising:
a launching module configured to launch an autonomous underwater vehicle (AUV) in water;
a recovery module configured to recover the AUV from the water;
a homing device mounted on the recovery module and configured to guide the AUV to the recovery module while in the water;
a management module connecting the launching module to the recovery module and configured to transport the AUV while on the vessel; and
an acoustic system configured to determine a location of the AUV and configured to activate the AUV when a time to return to the surface arises.

2. The vessel of claim 1 , wherein the management module is mounted on a deck of the vessel.

3. The vessel of claim 1 , wherein the management module comprises:
a transportation system configured to transport the AUV in a vertical position while on the vessel.

4. The vessel of claim 1 , wherein an end of the launching module and an end of the recovery module are underwater.

5. The vessel of claim 1 , wherein the recovery module includes a body having a cross-section that matches a cross-section of the AUV.

6. The vessel of claim 1 , wherein the recovery module includes guidance rollers configured to rotate in a desired direction for transporting the AUV from the water toward an upper part of the vessel.

7. The vessel of claim 1 , wherein the launching module includes a body having a triangular cross-section that matches a cross-section of the AUV.

8. The vessel of claim 1 , wherein the management module provides a single track for the AUV between the launching module and the recovery module.

9. The vessel of claim 1 , wherein the management module provides parallel tracks for the AUV between the launching module and the recovery module.

10. A vessel for performing a marine acoustic survey of a subsurface, the vessel comprising:
a launching module configured to launch an autonomous underwater vehicle (AUV) underwater;
a recovery module configured to recover the AUV; and
a management module connecting the launching module to the recovery module and configured to transport the AUV while on a deck of the vessel,
wherein the management module includes,
a first management zone configured to receive the AUV from the recovery module and to sort the AUV into damaged and undamaged AUVs;
a conveyor zone configured to receive the undamaged AUV; and
a second management zone connected to the conveyor zone and configured to receive the undamaged AUV,
wherein the second management zone is also connected to the launching module.

11. The vessel of claim 10 , wherein the management module comprises:
a transfer module configured to transfer the AUV from the recovery module to the management module.

12. The vessel of claim 10 , wherein the conveyor zone comprises:
a conveyor mechanism configured to move the AUV along the deck of the vessel.

13. The vessel of claim 10 , wherein an end of the launching module and an end of the recovery module are underwater.

14. A method for performing a marine acoustic survey of a subsurface, the method comprising:
deploying through a launching module an autonomous underwater vehicle (AUV) underwater;
guiding the AUV to a recovery module with a homing device mounted on the recovery module after the AUV has recorded seismic data of the subsurface;
recovering with the recovery module the AUV;
transporting the recovered AUV with a management module back to the launching module for redeployment; and
sorting the AUV into damaged and undamaged AUVs and passing the AUV to a corresponding path.

15. The method of claim 14 , further comprising:
inspecting the AUV after passing the recovery module.

16. The method of claim 14 , further comprising:
removing the seismic data from the AUV while passing the management module; and
recharging or replacing a battery of the AUV while passing the management module.

17. The method of claim 14 , further comprising:
maintaining the damaged AUV in a maintenance module that is separated from the management module.
