  • Publication number: 20180224568
    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.

  • Publication number: 20180222560
    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.
