Relation of Inspection Findings to Fatigue Reliability

Abstract

The main objective of this work was to develop an aperiodic inspection procedure for marine structures so as to maintain their reliability at a predetermined design level throughout the design life. A summary of current inspection procedures for a variety of marine structures is provided. Limited information makes it very difficult to assess the reliability of inspection techniques. Probability of detection (POD) curve used in the aerospace industry for flaw detection were reviewed and provided a guide for establishing POD curves for the marine industry. Aperiodic inspection procedures based on Bayesian upgrading and POD cures, component stress levels, and structural inspection and repair histories are developed. Validity and effectiveness of the Bayesian analysis is demonstrated by numerical example. Current inspection procedures are generally incompatible with the probabilistic approach this work intends to develop.
