A field test was conducted with autonomous marine vehicles (AMVs) and 3D sensor arrays (3DSAs) to record and compare seismic data generated during an ocean-bottom-cable (OBC) survey. The test was a field verification to check that the AMV platform and the sensor array can deliver high-quality seismic data in a form that can be successfully processed and compared with ocean-bottom fixed-receiver data. The feasibility test conducted offshore Abu Dhabi demonstrated the successful and safe deployment, seismic-data acquisition, and retrieval capabilities of the AMV and 3D sensor array.


AMVs are an alternative to conventional methods of acquiring marine seismic data; they are designed with the aim of increasing offshore safety and reducing risk while delivering a quality service within lower-cost pricing models. These unmanned vehicles have expanded the envelope of offshore operations and have been instrumental in increasing productivity and safety in marine environments. Such vehicles, because of their low profile and flexibility in maneuvering around obstructions, can be placed close to obstructions, reducing the risk typically involved in operations of this nature. The vehicles have proved capable of carrying out a wide range of vital ocean-monitoring functions formerly assigned to manned vessels over a longer time period and provide a viable alternative or supplement to acquiring seismic data in cases where adverse existing factors may impede standard acquisition methods.
