“…In recent years, autonomous marine vehicles (AMVs) towing sources have been proposed by Berkhout (2012) and Chalenski et al (2017). Surface AMVs towing and controlling underwater streamers have been developed and demonstrated by Moldoveanu et al (2017) and Haumonté (2017), whereas autonomous underwater vehicles equipped with seismic sensors have been proposed by Essaouari and Turetta (2016) and Tsingas et al (2017). The emergence of such AMVs enable new and potentially cost-effective solutions to seismic survey design that needs to be evaluated (Blacquiere and Berkhout 2013).…”

“…Currently, AMVs with the ability to sail a limited distance to and from their target position are in development and can replace expensive ROV deployments (Tsingas et al 2017). These AMVs are launched from a basket positioned above the seabed, are able to land at the desired seabed location and can take off from the seabed and return to the basket.…”

Autonomous marine vehicles instrumented with seismic sensors allow for new efficient seismic survey designs. One such design is the swarm survey, where a group, or swarm, of slow moving autonomous marine vehicles record seismic data from shots fired by a source vessel sailing around circles within the swarm. The size of the swarm is dictated by the maximum offset requirement of the survey, and it can be shaped to acquire wide‐ and full‐azimuth data. The swarm survey design equation describes the relationship between the source and receiver positions of the survey and the subsurface coverage or fold. It is used to adapt the swarm to the seismic survey requirements and to calculate survey duration time estimates as function of available equipment. It is shown that a survey conducted by a slowly moving swarm requires six times fewer shots than an equivalent seabed node survey conducted over 85.5 km2. Swarm surveys can also be adapted to efficiently conduct infill surveys and replace multi‐vessel undershoots. The efficiency of the survey can further be increased when the autonomous marine vehicles are towing short streamers with multiple receivers. Synthetic tests show that the seismic images for swarm surveys are comparable to those from streamer surveys, while little variation in image quality is found when reducing the number of autonomous marine vehicles but equipping them with a short streamer with multiple receivers.
