It is to be noted that the described direct procedure leads to an automatic determination of damage cases. Also, this fully automatic procedure does not need the preliminary “zonification” process, which is instead required when using analytical “p-factors”, as in case of SOLAS2009. For such reason, this procedure can be referred to as “non-zonal”. Furthermore, this procedure does not have any limitation regarding the actual shape of the compartments. Since the outcome from this procedure is affected by sampling uncertainty, the number of generated breaches must be large enough to achieve an acceptable convergence of the attained subdivision index. The general logic of the proposed direct non-zonal approach is shown in Fig. 1.
