Recently, classification societies have taken an interest in the statistical approach to ship longitudinal strength and the probabilistic methods for defining new design criteria. This interest is partially a result of the development and the growing demand for large tankers; it is reflected in the increasing research done by the regulatory bodies in these areas. This paper presents a framework for an approximate probabilistic method to calculate ship longitudinal strength with possible implementation in classification societies rules in mind. The most important features of this method are that it is simple, realistic, consistent, and distribution-free. No assumptions are made with regard to the forms of the distribution functions of the random variables involved in the procedure. Nevertheless, the uncertainties associated with these variables are taken into consideration and are quantified by their coefficients of variation. Analyses of eighteen ships of different types are made in order to serve as a preliminary investigation of the appropriate level of safety as measured by a proposed safety index.
