Abstract: The traditional submarine cable seismic node layout is greatly affected by water current and seabed topography, which make it difficult to ensure the quality of data acquisition and equipment safety. However, the ROV has excellent adaptability and engineering intervention ability to marine environment. In order to explore a new method for submarine seismic node layout, this paper discussed the feasibility of underwater seismic node deployment by ROV system. We compared it with the traditional water surface deployment, and both the advantages and limitations of ROV technology, and future prospects of the technology are presented and analyzed. As a new method, ROV node layout technology with higher accuracy and safety can be used as a supplement to the traditional layout method. In the future, it will be widely used in the submarine seismic node layout and related fields.
