Abstract
A method for cycling autonomous underwater vehicles (AUVs) that record seismic signals during a marine seismic survey. The method includes deploying plural current AUVs on the ocean bottom; recording the seismic signals during the marine seismic survey with plural current AUVs; releasing from an underwater base a new AUV to replace a corresponding current AUV from the plural current AUVs; recovering the current AUV; and continuing to record the seismic signals with the new AUV.
Claims21
A method for cycling autonomous underwater vehicles (AUVs) that record seismic signals during a marine seismic survey, the method comprising:
- deploying plural current AUVs on the ocean bottom;
- recording the seismic signals during the marine seismic survey with plural current AUVs;
- releasing from an underwater base a new AUV to replace a corresponding current AUV from the plural current AUVs when a predetermined condition is met, wherein the new AUV is separate from the plural current AUVs;
- recovering the current AUV;
- and
- continuing to record the seismic signals with the new AUV.
A method for cycling autonomous underwater vehicles (AUVs) that record seismic signals during a marine seismic survey, the method comprising:
- recording the seismic signals during the marine seismic survey with plural current AUVs deployed on the ocean bottom;
- replacing during the seismic survey a current AUV from the plural current AUVs with a new AUV when a predetermined condition is met, wherein the new AUV is separate from the plural current AUVs;
- and
- continuing to record the seismic signals with the new AUV.
A method of rolling autonomous underwater vehicles (AUVs) that record seismic signals during a marine seismic survey, the method comprising:
- recording the seismic signals during the marine seismic survey with plural AUVs deployed on the ocean bottom, wherein the marine seismic survey comprises an area to be surveyed, wherein the area to be surveyed comprises an active recording area, an already recorded area, and a future recording area;
- instructing an AUV from the plural AUVs, after recording the seismic signals, to move to a new location in the future recording area to be surveyed;
- continuing to record the seismic signals with the AUV at the new location during the same marine seismic survey;
- releasing from an underwater base a new AUV to replace a corresponding AUV from the plural AUVs, wherein the new AUV is separate from the plural current AUVs;
- recovering the replaced AUV;
- and
- continuing to record the seismic signals with the new AUV.
