    Research output: Patent


    A method of testing the through cut of a pipeline comprising at least the steps of: (a) transmitting an electromagnetic signal through the pipeline; (b) monitoring any reflected signal (s); and (c) interpreting the or each reflected signal to test for the through cut of the pipeline. In this way, a non-invasive electromagnetic signal can be passed through, along, across or otherwise within the pipeline, and any reflected signal(s) can be interpreted and analysed based on one or more characteristics of the received signal(s) to ascertain the change in the conductivity of the pipeline due to the cutting thereof, in particular when or whether the cutting of the pipeline is complete or has been completed such that there is a through cut.
