The computational method is based on the Reynolds Averaged Navier-Stokes Equations (RANSE) solver and the experiment was carried out in the towing tank at Ship Design and Research Centre S.A. with the use of a scale model. The analysis was focused on the safety of water entry, i.e. the maximum pitch and roll angles, the maximum acceleration, as well as the occurrence and degree of flooding of bonnet and windscreen. Both the computations and the experiment have revealed that in the case of free water entry, i.e. without braking, the water covers the windscreen even at a moderate slope of the beach (10°); however, if braking of the wheels during the water entry process were possible, the flooding of the bonnet and windscreen could be avoided even at a steep slope (30°).

It is devoted to the design stage and difficult to apply in operation. A possible alternative described in this paper is a method based on assessment of performance of ships and risk assessment. Type of risk evaluation is the quantitative risk assess-ment. The matrix type risk model has been applied for estimation the riskand the measure of safety of ships level is based on the risk acceptance criteria from the risk matrix. After the risk assessment the method may be used for the safety management purposes using the risk control options.

Some conclusions following from the research associated with development of a method for safety assessment of ships in abnormal/damage conditions is presented in the paper. The method called SSAMADC (Ship Safety Assessment Method in Abnormal/Damage Conditions) is a risk-based method and is connected with application of the quantitative risk assessment QRA approach. The method is an alternative method of safety assessment of ships in abnormal/damage conditions in comparison with the method included within the SOLAS 2009 regulations. The aim of the research is to work out a proposal of an alternative method of safety assessment of ships in damaged conditions. There is a lack of such the method for the certain type of ships.

The model is devoted towards assessing the performance of the damaged ro-ro ships at the preliminary stage of design. The key problems associated with preparing of such the model are associated with working out a method of assessment of the damaged roro ships performance, investigating all the phenomena which associated with the flooding process of the damaged ro-ro ships and preparing the model itself. Introducing the method of assessment of the damaged roro ships performance it has been assumed that there is a dependence between the arrangement of internal spaces of a ro-ro ship and flooding process. The major phenomena which have been decided to take into account when considering flooding of the ro-ro ships are the flooding understood as the flow of external water into the data damaged compartment, impact of the flooding water on the ship structure and damaged ro-ro ship motion. Knowing the damaged ro-ro ship motion characteristics in time domain it is relatively easy to assess the damaged ro-ro ship performance according to the heeling angle and assess the ro-ro ship design according to the data arrangement of internal spaces. The last research issue is to investigate if the proposed model may be appropriate tool for assessing the performance of the ro-ro ships in damaged conditions at the preliminary stage of design. The aim of this paper is to show how to incorporate the dynamics of the damaged ro-ro ships when assessing the ship performance and safety at the preliminary stage of design. The basic information on the model for estimation of the damaged ro-ro ship behavior during the flooding process is presented. The complexity of this model is shown depending on the approach applied to consider the flooding process itself. The model is devoted towards assessment of performance of the damaged ro-ro ships and it is still under the development according to a Ph.D. research at the

The objectives of investigations are briefly described including the method introduction. Special attention is paid towards application of the direct and indirect methods. Four modules of the computational model are presented including those connected with the ship/environment definition, hazard identification, hazard and risk assessment. Then, the hazard and risk assessment modules are used to show an application. A simplified cargo type ship is defined to demonstrate how the computational model can enable the risk assessment to be done for the given initiating event and scenario development (it follows from the assumed scenario of flooding the watertight compartments). The risk assessment results can be used by both the risk reduction and risk management procedures. The preliminary practical remarks regarding the ships safety estimation in critical conditions using the presented method and computational model are given.
