7. CONCLUSIONS
The Integrated Ship Safety Estimation Method (ISSEM) has been worked out and it is directed towards the ship safety estimation in critical conditions at the preliminary stage of design. Using the ISSEM method the hazard and risk assessment may be done according to the IMO regulations for cargo ships. In the case when there is no possibility to assess the hazards (for example for special types of ships) an alternative procedure has been prepared for the risk assessment. So far, the ISSEM method and computational model have been used for investigating the new solutions regarding the ships safety from the damage stability and survivability point of view. The method can be used for intelligent guiding ship subdivision for safety. A few arrangements of internal spaces for cargo ships including either transverse or combined subdivision have been investigated. Both the damage stability and survivability/risk assessment were done for each case. The method can use semi-probabilistic and probabilistic safety measure procedures. It can be classified as a combined "parametric - risk-based assessment method" for the ship safety estimation in critical conditions, at the preliminary stage of design.
