DEPLOYMENT AND RECOVERY OF AUTONOMOUS UNDERWATER VEHICLES FOR SEISMIC SURVEY

摘要

A system and method for performing a marine seismic survey of a subsurface. The method includes deploying under water, from a deploying vessel ( 202), a number of autonomous underwater vehicles (AUV) (100); recording with seismic sensors located on the AUV seismic waves generated by an acoustic source array (230); 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.
