Rational ship hull design calls for consideration of structural safety as well as for economics. This boils down to the question of how best to optimize the allowance for potential hull structure failures, and for that purpose employing the reliability concept is a sensible approach to take. Regarding the detailed ship hull structural design, the author performed, for clarification of the logic and allowance of fatigue failure, Fault Tree Analysis and Fuzzy Sets Based Analysis to determine structural strength requirements of proper reliability. The author designed, using assumed stress conditions, frame end structures. In this, structural stress concentration factors for a number of frame end structures , results of actual hull structural failure analysis, and the scatter in theoretical and experimental data on the crack initiation and propagation in frame ends were used to select the detailed frame end profiles which could offer adequate reliability for the required structural integrity from the points of view of crack initiation and propagation lives.
