ABSTRACT:
Cable deployment in a fluid filled pipeline under pressure is monitored by use of a strain gauge device coupled between the leading end of the cable and a drogue. The strain gauge measures the pull of the drogue on the leading end of the cable and the strain gauge signal is transmitted back to the other end of the cable via the cable conductors. Changes in fluid flow rate, features of the pipeline, and failure of the drogue to inflate can be detected quickly by monitoring the strain gauge signal, so that the cable feed rate can be changed accordingly in order to maintain satisfactory deployment.
