Abstract

For ship operators, navies in particular, who demand high standards of performance and reliability, non-destructive testing during operation is taking on a vital role. The hull is subjected to mechanical stresses, comprising an element of fatigue arising from wave motion and from operation of the propulsion systems. In naval craft, a further contribution arises from the irregular pattern of weapon use. Variation in the amount and duration of loads makes it difficult to determine with certainty how dangerous observed faults are. The risk of over-approximation in determining the criticality of damage has until now necessitated an approach based on preventive replacement of components according to the pattern of use or as and when defects are discovered, always leaving sufficient safety margins to guarantee full efficiency at sea. This report discusses the effectiveness of another approach to the problem, that of integrating periodic inspections of the ship with the use of non-destructive investigative techniques, which are presented here to show their potential for adaptation to naval application.
