A clear tendency of moving from prescriptive to performance based safe
ty regulations is emerging internationally. Introduction of performanc
e standards is seen as beneficial to industry, allowing consideration
of alternative designs as well as a rapid implementation of technologi
cal innovation. In this respect, the analysis of alternative design so
lutions, particularly in the case of Ro-Ro ferries, requires the devel
opment of a standardized approach to demonstrate compliance with the r
equirements of intact and damage stability regulations by a combinatio
n of physical model experiments and numerical model tests while applyi
ng probabilistic techniques in the process of assessing damage surviva
bility. The procedure pertaining to model experiments is described in
the SOLAS Regulation II-1/8 and the ''Interim Guidance Notes for a Uni
form Model Test Procedure'' relating to this regulation. This paper co
ncentrates on the development and validation of a mathematical model t
o be used for numerical model testing and the proposal of rational sur
vival criteria allowing for a probabilistic assessment of the dynamic
stability of damaged ships, in a way that could not be simpler for pra
ctical applications.
