Assessment of the Effect of Pitting Corrosion on the Safe Life Prediction of the P-3C

Abstract

This report presents the results of an experimental programme aimed at assessing the implications of pitting corrosion damage on P-3C safe lives calculated using the methods developed in the P-3C Service Life Assessment Program, the Equivalent Crack Size method and the Crack Initiation method. The results of both of these methods were that, for the pitting corrosion distribution used, the safe life prediction was not invalidated by corrosion. However, larger corrosion pits or a change of corrosion mechanism may invalidate safe life predictions.
