Abstract

The paper considers the fracture assessment of a ship structure containing multiple crack sites. Fatigue cracks initiated from welded defects, under extreme dynamic wave loading can lead to fracture of the vessel. The effect of multiple crack sites on the probability of failure is studied. Time dependent reliability analysis is performed using Monte Carlo simulation, with some emphasis on the inspection and repair planning. Correlation effects on basic variables are also studied.
