Description

The deposition of a scale on off-shore steel structures by a cathodic protection system often obscures surface defects, especially fatigue cracks. The problems and high cost associated with clearing such structures prior to inspection are well known [1] and a recent report [2] has considered many of the aspects of this scale. To avoid the need to remove such scale various ultrasonic techniques can be considered to perform inspections through the deposited layers.
