Abstract

Embodiments, including apparatuses, systems and methods, for attaching autonomous seismic nodes to a deployment cable. In an embodiment, an apparatus includes a seismic node having a direct attachment mechanism configured to directly attach the seismic node to a deployment line, the direct attachment mechanism being configurable between an open and/or unlocked position and a closed and/or locked position to release and retain the deployment line.

Claims (32)

1. An attachment device for attaching a seismic node to a deployment line, comprising:

at least one in-line receiving device configured to receive a portion of a deployment line; and

at least one locking device configured to secure the portion of the deployment line to the at least one in-line receiving device, wherein the at least one locking device is moveable between a locked position and an unlocked position within the in-line receiving device,

wherein the at least one in-line receiving device comprises one or more grooved protrusions, wherein the one or more locking devices is located within the one or more grooved protrusions,

wherein the attachment device is located on a surface of the seismic node.

2. The attachment device of claim 1 , wherein the attachment device comprises a leading end that is configured to receive the deployment line and a trailing end that is configured for retaining the deployment line.

3. The attachment device of claim 1 , wherein the one or more grooved protrusions is configured to receive the deployment line within a groove of the grooved protrusion.

4. The attachment device of claim 1 , further comprising at least two locking devices, wherein each of the at least two locking devices is arranged on opposite sides of the at least one in-line receiving device.

5. The attachment device of claim 1 , wherein the attachment device is located on an upper surface of the seismic node.

6. The attachment device of claim 1 , wherein the at least one locking device comprises a biased resilient member for returning the at least one locking device to a locked position.

7. The attachment device of claim 1 , wherein the attachment device is configured to provide increased fastening of the deployment line as the in-line force from the deployment line increases.

8. The attachment device of claim 1 , further comprising a plurality of oppositely arranged ridges for increased fastening of the deployment line to the attachment device.

9. The attachment device of claim 1 , wherein the least one in-line receiving device comprises a body having an opening at one end for receiving the deployment line, a back wall portion, and a top portion.

10. The attachment device of claim 9 , wherein the deployment line is retained against the back wall portion of the body.

11. The attachment device of claim 9 , wherein the deployment line is retained within the body.

12. The attachment device of claim 1 , wherein the at least one locking device is configured to be pushed open upon engagement with the deployment line.

13. The attachment device of claim 1 , wherein the at least one locking device is configured to return to a locking position after receiving the deployment line.

14. The attachment device of claim 1 , wherein the at least one locking device is configured to retain the deployment line within the receiving device until the at least one locking device is actuated.

15. The attachment device of claim 1 , wherein the one or more receiving devices is in the shape of a hook.

16. The attachment device of claim 1 , wherein the at least one locking device comprises a spring lock.

17. An attachment device for attaching a seismic node to a deployment line, comprising:

at least one in-line receiving device configured to receive a portion of a deployment line; and

at least one locking device configured to secure the portion of the deployment line to the at least one in-line receiving device, wherein the at least one locking device is moveable between a locked position and an unlocked position within the in-line receiving device,

wherein the at least one in-line receiving device comprises a body having an opening at one end for receiving the deployment line, a back wall portion, and a top portion, wherein the body is substantially hook shaped,

wherein the attachment device is located on a surface of the seismic node.

18. The attachment device of claim 17 , wherein the body comprises one or more grooved protrusions.

19. The attachment device of claim 18 , wherein the deployment line is retained within one or more grooves of the grooved protrusions.

20. The attachment device of claim 17 , wherein the deployment line is retained against the back wall portion of the body.

21. The attachment device of claim 17 , wherein the at least one locking device is located within the body.

22. The attachment device of claim 17 , wherein the at least one locking device comprises a spring lock.

23. The attachment device of claim 17 , wherein the attachment device is located on an upper surface of the seismic node.

24. The attachment device of claim 17 , wherein the attachment device is configured to directly attach the deployment line to the seismic node.
