A method of replacing an electronics module in a seismic cable on the open s ea, (as well as a device for use in the replacing) where the replacement is carried out with the aid of a small boat equipped with ca ble rollers, the method comprising positioning the part of the cable including the electronics module on a first and a second cable rol ler respectively in such a way that the electronics modu le and its couplings are located between the two rollers, clamping the sections of cable on either side of the electronics module in a firs t and a second clamping arrangement (1, 2) respectively, with the clamping arrangeme nt connected together via a mechanical tensioning device (3), moving the clamped sections of cable towards each other using the tensi oning device in such a way that the tension in the seism ic cable is taken up by the tensioning device, after which the electronics module can be removed and replaced after which the tensioning devi ce (3) is slackened slightly and the clamping arrangement (1, 2) is released from t he sections of cable before the part of the seismic cabl e with the new electronics module is replaced in the sea. |
