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.
Claims24
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.
