摘要： Seismic autonomous underwater vehicles (AUVs) for recording seismic signals on the seabed. The AUV may be negatively buoyant and comprise an external body (which may be formed of multiple housings) that substantially encloses a plurality of pressure housings. Portions of the external body housing may be acoustically transparent and house one or more acoustic devices for the AUV. The AUV may comprise a main pressure housing that holds substantially all of the electronic components of the AUV, while a second and third pressure housing may be located on either side of the main pressure housing for other electronic components (such as batteries). A plurality of external devices (such as acoustic devices or thrusters) may be coupled to the main pressure housing by external electrical conduit. The AUV may comprise fixed or retractable wings for increased gliding capabilities during subsea travel.

摘要： A high angle overboard system and method for the deployment of subsea equipment from a marine vessel. The overboard guide system deploys a deployment line from a surface vessel into a body of water at an angle alpha. The angle alpha may be at least 15 degrees and may be greater than 20, 25, 30, 45, or even 60 degrees or more during some or all portions of the subsea operations. The overboard system may be located near the splashzone of the surface vessel or a distance beneath a water surface. The overboard system may take any number of configurations, such as a cone shape, and/or may comprise a plurality of rollers or one or more sheaves. The overboard system allows a subsea device to be operated at higher deployment angles as compared to prior art subsea operations, such as with A-frame LARS systems.

摘要： Embodiments, including systems and methods, for deploying ocean bottom seismic nodes. Two or more underwater vehicles (such as remotely operated vehicles (ROVs)) may be deployed by a surface vessel and each connected to the surface vessel by a ROV deployment line. A catenary shape of each ROV deployment line may be modeled for more accurate and efficient subsea ROV operations. Real-time modeling and predictive modeling of the catenary shape of the deployed lines may be performed, and the surface vessel and/or ROVs may be positioned based on the modeled catenary shapes. The ROVs may be automatically positioned and/or controlled based on commands from a dynamic positioning (DP) system. An integrated navigation system (INS) may be located on the surface vessel and directly coupled to the one or more DP systems. The surface vessel may travel backwards during deployment operations and deploy one or more subsea baskets astern from the ROVs.

摘要： Apparatuses, systems, and methods for data and/or power transfer to and from an ocean bottom seismic node are described. In an embodiment, an autonomous seismic node is configured with a bulkhead connector assembly that may be coupled to a plug assembly for data and/or power transfer and a pressure cap assembly when utilized subsea. A plurality of pins may be located on the bulkhead assembly in a substantially flat contact surface to obtain an external electrical connection to the node. The pins on the bulkhead assembly may form a flat circuit with an external device, such as a plug assembly or pressure cap assembly. One or more external devices may be coupled to the pressure cap assembly and/or bulkhead connector for increased functionality to the node. A quick release assembly and/or locking ring may be utilized to fasten any external device to the bulkhead connector assembly.

摘要： 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.

摘要： Apparatuses, systems, and methods for the deployment of a plurality of autonomous underwater seismic vehicles (AUVs) on or near the seabed based on acoustic communications with an underwater vehicle, such as a remotely operated vehicle. In an embodiment, the underwater vehicle is lowered from a surface vessel along with a subsea station with a plurality of AUVs. The AUVs are configured to acoustically communicate with the underwater vehicle or a second surface vessel for deployment and retrieval operations. The underwater vehicle and/or second surface vessel is configured to instruct the AUVs to leave the subsea station or underwater vehicle and to travel to their intended seabed destination. The underwater vehicle and/or second surface vessel is also configured to selectively instruct the AUVs to leave the seabed and return to a seabed location and/or a subsea station for retrieval.

摘要： Systems and methods for deploying seismic autonomous underwater vehicles (AUVs) to the seabed by using a variety of guidance systems and/or positioning/communication protocols based on a particular AUV's location. A combination of a USBL system and a phased array system may be used to deploy different groups of AUVs on one or more deployment lines of a seismic survey area. The deployment lines may be generally perpendicular or parallel to a deployment vessel's direction of travel. Once a certain number of AUVs have landed on the seabed, the landed AUVs may be used to guide flying AUVs to their intended seabed destination by using acoustic pingers and phased array techniques. Time intervals for acoustic signals emitted from landed AUVs may be generated using a predetermined Time of Emission pattern and received by a phased array receiver on flying AUVs.

摘要： 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.
