A seismic data acquisition system comprising:
- a streamer spread including (i) a streamer having receivers for recording seismic data and (ii) a connecting cable connecting the streamer to a towing vessel;
- a collar device configured to move along the connecting cable, between the towing vessel and the streamer;
- and
- a remotely operated vehicle, ROV, attached to the collar device with an umbilical and configured to carry an interchangeable payload.
A payload system for performing various operations on a streamer spread of a marine seismic data acquisition system, the payload system comprising:
- a collar device to be attached to a connecting cable, which extends between a towing vessel and a streamer of the marine seismic data acquisition system;
- and
- a remotely operated vehicle, ROV, attached to the collar device with an umbilical and configured to carry an interchangeable payload.
A method for performing various operations on a streamer spread of a marine seismic data acquisition system, the method comprising:
- attaching a collar device to a connecting cable, which extends between a towing vessel and a streamer;
- connecting a remotely operated vehicle, ROV, to the collar device with an umbilical;
- attaching a desired interchangeable payload to the ROV;
- and
- operating the collar device along the connecting cable and controlling a length of the umbilical to position the ROV at a desired position of the streamer spread for performing one operation of the various operations.
