Abstract: Disclosed is an ocean bottom seismic node for recording seismic signals on the seabed. The ocean bottom seismic node may comprise an arched cathedral buoyant body coupled to a substantially flat bottom metal plate. The buoyant body may be formed of hard plastic (such as plastic injection in a mold) and have one or more cathedral type inner structures with columns that form a plurality of interconnected inner chambers, which may be dry or filled with foam and/or act as ballasts. One or more electronic components may be directly attached to the bottom metal plate (and within one or more of the internal cathedral chambers) and covered/protected by the buoyant body that is water and pressure resistant at seabed depths. The edge(s) of the buoyant body may seal around the metal plate on one or more peripheral edges of the plate and buoyant body.

Abstract: 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.

Abstract: 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.

Abstract: Systems and methods for operating a modular and/or containerized seismic source array system from a marine vessel and installation of same on any vessel of opportunity. The system may be transported, stored, and operated in a plurality of containers, each of which may be CSC approved ISO shipping containers. The containers are attached to the marine vessel by a grid attachment frame installed on the back deck of the vessel, such that a wide variety of container configurations is possible. The containers may be placed longitudinally and transversely on the grid attachment frame and may be multiple levels high. A detachable/removeable slipway may be utilized at the rear of the vessel to facilitate deployment and retrieval of the source arrays. The source array system can be combined with an ocean bottom node deployment or recovery system on the same vessel by utilizing same or similar container footprints.
