Risk and operation optimized damage detection and inspection systems

Damage detection systems are usually developed and optimized based on the methods of damage detection system reliability. This implies that the later purpose of a damage detection system namely e.g. the employment of the structural integrity management is not directly accounted for. This paper addresses thus the issue of optimizing a damage detection system in the perspective its utilization for the structural integrity management. The approach is developed based the integral consideration of a) damage detection reliability and risks and b) the structural reliability and risks. The approach is developed starting with formulating the damage detection system reliability in terms of determining the conditional probability of indication and... (More)
Damage detection systems are usually developed and optimized based on the methods of damage detection system reliability. This implies that the later purpose of a damage detection system namely e.g. the employment of the structural integrity management is not directly accounted for. This paper addresses thus the issue of optimizing a damage detection system in the perspective its utilization for the structural integrity management. The approach is developed based the integral consideration of a) damage detection reliability and risks and b) the structural reliability and risks. The approach is developed starting with formulating the damage detection system reliability in terms of determining the conditional probability of indication and of no indication. The structural reliability model is developed explicitly accounting for damage and failure of a structure. On the basis of the formulation of an event tree it is described how the expected operational costs, the structural risks can be calculated and how risk based indices are derived. The approach is applied to a case study focusing on a damage detection system employment on a structural component subjected to fatigue. The introduced approach is discussed for the specific case study and the expected operational costs and the structural risks are determined. This in turn facilitates the determination of optimal parameters and indices of the damage detection system for the individual service years.
