<p>A method for managing a multi-vessel seismic system comprising a first vessel (V1), having a recording system and towing at least one streamer integrating seismic sensors, and a second vessel (V2), comprising at least one seismic source performing shots. The second vessel sends to the first vessel, via a radio link, a plurality of series of shot predictions (TP). For each shot, the second vessels activates the seismic source according to the predictions and sends to the first vessel, via the radio link, shot data (FTB, GH, SP) relating to the shot. The first vessel activates the recording system, in order to record seismic data, either non-continuously and according to a last received series of shot predictions, or continuously. If, by analyzing a received series of shot predictions, the first vessel detects that it has not received the shot data relating to at least one performed shot, then the first vessel sends a request (RD1) to the second vessel and receives in response the missing shot data (RD2). For each performed shot and the related shot data, the system selects seismic data as a function of the related shot data, and combines (49) the selected seismic data with the related shot data in order to obtain combined data whose interpretation allows to obtain a seabed representation.</p> |
