摘要
the invention aims to provide a method for non-destructive inspection of a flexible underwater tube (10) capable of detecting a flood of the annular space (13) in which the shield layers are found (14, 23). the method comprises the following steps: - have at least one pair of electrodes (101, 102) in the vicinity of the outer sheath (11), - measure the impedance at the terminals of the electrode pair, at a frequency advantageously between 10 hz and 10 mhz , - compare the measured impedance with reference values, in order to determine the nature of the fluid contained in the annular space (13).
