Abstract:
Embodiments, including apparatuses, systems and methods, for automatically attaching and detaching seismic devices to a deployment cable, including a plurality of autonomous seismic nodes. A node installation system may include a moveable node carrier coupled to a cable detection device and a node attachment device that is configured to move a direct attachment mechanism on a node into a locking or closed position about the deployment cable. In an embodiment for retrieval and/or detachment operations, the system may also be configured to automatically detect the position of a node and remove the node from the deployment line by actuating the direct attachment mechanism into an open or unlocked position. Other devices besides a node may be attached and detached from the deployment line if they are coupled to one or more direct attachment mechanisms.
Abstract:
Apparatuses, systems, and methods for the deployment of a plurality of seismic autonomous underwater vehicles (AUVs) on or near the seabed. In one embodiment, the AUV comprises a buoyant body coupled to a pressure vessel that contains substantially all of the AUV's electronic components. The pressure vessel may comprise a plurality of composite components coupled together by a metallic ring to provide a substantially cylindrical shape to the pressure vessel. The AUV body provides lift to the AUV during lateral movement and compensates for an overall negative buoyancy of the AUV. The AUV may include a plurality of thrusters for propulsion. A vertical thruster may be used to create an upwards attack angle during takeoff and to maintain depth and orientation during flight. During normal flight operations, the AUV is configured to travel horizontally and vertically in a body of water by using only the horizontal thrusters.

Abstract:
Containerized handling, deployment, and retrieval systems for deploying and retrieving a plurality of autonomous seismic nodes from the back deck of a marine vessel are presented. The handling system may comprise a deployment system and a node storage and service system fully contained within a plurality of CSC approved ISO containers. Each of the components of the handling system may be located in a CSC approved ISO container for storage, operation, and transport. In one embodiment, the node deployment system is configured to retrieve and deploy autonomous seismic nodes from the back deck of a vessel. In one embodiment, the node storage and service system is configured to transfer nodes to and from the node deployment system for storage and servicing.

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.
