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.

Deployment and recovery of autonomous underwater vehicles for seismic survey

Method and vessel for performing marine acoustic survey of a subsurface. The vessel includes a launching module configured to deploy an autonomous underwater vehicle (AUV) underwater; a recovery module configured to recover the AUV; a homing device mounted on the recovery module and configured to guide the AUV to the recovery module; and a management module connecting the launching module to the recovery module and configured to transport the AUV.
