ABSTRACT:
A device and method of replacing an electronics module in a seismic cable on the open sea, where the replacement is carried out with the aid of a small boat equipped with cable rollers, the method including positioning the part of the cable including the electronics module on a first and a second cable roller respectively in such a way that the electronics module and its couplings are located between the two rollers, clamping the sections of cable on either side of the electronics module in a first and a second clamping arrangement, respectively, with the clamping arrangements connected together via a mechanical tensioning device, moving the clamped sections of cable towards each other using the tensioning device in such a way that the tension in the seismic cable is taken up by the tensioning device, after which the electronics module can be removed and replaced after which the tensioning device is slackened slightly and the clamping arrangement is released from the sections of cable before the part of the seismic cable with the new electronics module is replaced in the sea.
