EVALUATION OF SURVIVABILITY OF A SHIP AFTER DAMAGE WITH APPLICATION OF A RISK CALCULATION METHOD

Abstract

This paper contains calculations of risk for a selected damage case scenario. The calculations took place with use of a risk model designed for evaluating the safety of ships and were compared with the available and published industry standard (as included in SOLAS 2009) as well. The comparison of results is presented in the form of a discussion and concludes that exact risk levels can be obtained at any stage of the vessel's life. The currently valid method as included in SOLAS 2009 regulation provides limited information about the actual survivability of a vessel in emergency conditions. It is hence very difficult to compare the current probabilistic model with risk based survivability calculations to evaluate the actual safety provided by an investigated vessel should it subsequently be severely damaged.
