DAMAGE STABILITY ASSESSMENT - STATE OF THE ART

At the present time it is not possible to determine, with reasonable accuracy, criteria for capsizing of ships in waves which are crucial for the assessment of damaged ship safety. However, based on the results of damage stability model experiments, it is possible to derive a simplified relationship which takes into account only certain parameters and disregards others. Such a situation is reflected in the present criteria on damage stability. The background to these criteria is briefly discussed in this paper. The paper emphasizes that relying on model tests only is not sufficient to make much progress and therefore more research is essential. Damage stability is a complex problem involving a large number of variables and the results from only one or two given ship shapes are not sufficient to identify the significant parameters governing the problem. Full benefit from test results will not therefore be achieved until there is a consistent logical theory which will enable the results to be generalised to other ship forms and sizes. At the moment such theory does not exist. The paper briefly discusses two possibilities of creating such a theory, one based on a simplified model of damaged ship behaviour and the other on a comparative method. Finally, the paper discussed practical calculation of the factors accounting for the damage stability of the ship in subdivision calculations.
