  • Deployment and recovery of autonomous underwater vehicles for seismic survey
    Patent number: 9969470
    Abstract: A system and method for performing a marine seismic survey of a subsurface. The method includes deploying under water, from a deploying vessel, an autonomous underwater vehicle (AUV); recording with seismic sensors located on the AUV seismic waves generated by an acoustic source array; instructing the AUV to surface at a certain depth relative to the water surface; recovering the AUV by bringing the AUV on a recovery vessel; and transferring recorded seismic data to the recovery vessel.
    Type: Grant
