AUTOMATED OCEAN BOTTOM SEISMIC NODE IDENTIFICATION, TRACKING, DEPLOYMENT, AND RECOVERY SYSTEM AND METHOD
A system, apparatus, and method for individually identifying, handling, tracking, deploying, and recovering a plurality of seismic nodes by an underwater vehicle for subsea operations. The deployment and positioning and retrieval of seismic nodes to and from the seabed may be managed automatically by software and/or manually automated by an ROV operator. The disclosed system may be coupled to a ROV navigation system. The node identification system tracks the position of each seismic node (associated with a unique identification number) within each tray or other node holder at all times, whether the tray is located on board a surface vessel, within an ROV, within a subsea basket, or on the seabed. The identification system is configured to track, select, deploy, and recover a particular seismic node by its unique identification number.

automatically recording each of the unique identification numbers for each of the plurality of node positions.
2 . The method of claim 1 , further comprising
automatically tracking the position of each of the plurality of seismic nodes within the node platform based on the unique identification number of each of the plurality of seismic nodes.
3 . The method of claim 1 , further comprising
automatically loading the plurality of seismic nodes on the node platform based on the unique identification number of each of the plurality of seismic nodes.
4 . The method of claim 1 , further comprising
automatically transferring the plurality of seismic nodes from the node platform based on the unique identification number of each of the plurality of seismic nodes.
5 . The method of claim 1 , further comprising
selecting one of the plurality of seismic nodes for transfer from the node platform based on the unique identification number of each of the plurality of seismic nodes.
6 . The method of claim 1 , further comprising
transferring the node platform with the plurality of seismic nodes onto a remotely operated vehicle.
7 . The method of claim 1 , further comprising
deploying each of the plurality of seismic nodes on the seabed at a predetermined position by a remotely operated vehicle based on the unique identification number of each of the plurality of seismic nodes; and

selecting one of the plurality of seismic nodes for deployment on the seabed;
automatically deploying the selected seismic node at a predetermined position on the seabed;
automatically determining a touchdown position of the node on the seabed; and
automatically recording the touchdown position of the node.
10 . The method of claim 9 , wherein the touchdown position comprises position coordinates, depth, and azimuth of the node.
11 . The method of claim 9 , further comprising automatically associating the touchdown position of the node with the unique identification number of the node.
12 . The method of claim 9 , further comprising automatically tracking the position of each of the plurality of seismic nodes within the remotely operated vehicle based on the unique identification number for each of the plurality of seismic nodes.
13 . The method of claim 9 , wherein the recording step comprises taking a picture of the node on the seabed.
14 . The method of claim 9 , wherein the positioning step is based on automated guidance from a navigation system.

17 . A method for the recovery of a plurality of seismic nodes on or near the seabed, comprising
automatically positioning a remotely operated vehicle proximate to a plurality of positions on the seabed, wherein a seismic node is located at each of the plurality of seabed positions, wherein each of the plurality of seismic nodes comprises a unique identification number;
automatically recovering a plurality of seismic nodes from the seabed by the remotely operated vehicle;
selecting one of the plurality of seismic nodes for recovery from the seabed based on a unique identification number of each of the plurality of seismic nodes; and
automatically identifying the unique identification number of each of the plurality of seismic nodes.
18 . The method of claim 17 , wherein the positioning step is based on automated guidance from a navigation system.
19 . The method of claim 17 , further comprising automatically tracking the position of each of the plurality of seismic nodes within the remotely operated vehicle.
20 . The method of claim 17 , further comprising
positioning the plurality of seismic nodes on a node platform within the underwater vehicle at a plurality of node positions within the node platform; and
automatically recording each of the unique identification numbers for each of the plurality of node positions.
