By using the knowledge gained from the inspection data, failure of the ship’s structural components may be avoided. Crack propagation is an important issue to consider when devising an appropriate inspection plan; this is particularly true for ships and FPSOs that operate in regions with high sea states. On some types of ships, it can be very difficult to perform inspections due to certain structural arrangements, for example wall fascias that hide the structural members, and the time required to perform this task leads to heavy costs. Thus, it is important to know the exact behaviour of how cracks propagate in order to determine, as far as possible, if the inspection process may be delayed. The original feature of the methodology is the use of Line Spring Method to calculate the stress intensity factors. Based on this approach, we have developed a probabilistic analysis using Monte Carlo simulation.
 The main benefit of this assessment technique is the added flexibility in the development of an inspection plan that best suits the ship or FPSO considered. This approach may help operators and engineers to make decisions for inspections, repairs and maintenance processes, in order to have the lowest cost whilst complying with the required safety targets. Finally, an example is provided on a ship’s deck beam, which shows us the effects of inspection parameters on the probability of failure and probability of detection.
