Abstract
A system (1) for detecting and locating corrosion on the outer surface of a metal body (2). The system includes an extended electromagnetic waveguide (6) arranged adjacent to the outer surface of the metal body. The electromagnetic waveguide includes a sacrificial component that experiences substantially the same environment as the outer surface of the metal body. The system also includes a waveform generator (10) arranged to be connected to the waveguide and to inject an electromagnetic waveform into the waveguide. The system also includes a waveform analyser (12) connected to the waveguide. The waveform analyser is arranged to receive a reflected portion of the injected electromagnetic waveform from the waveguide. The reflected portion of the injected electromagnetic waveform is used by the waveform analyser to determine the location of corrosion of the sacrificial component of the waveguide.
