As the role of modern naval non-combatants evolves to include multi-mission ships increasing their exposure to asymmetric threats and as damage can also occur accidentally outside of an intentional weapon impact, the assessment of survivability of non-combatant ships becomes necessary to ensure fleet-wide mission capability. A survivability enhancement case study was performed by modifying and applying traditional combatant survivability methodology to the 145m non-combatant naval training and hospital vessel shown above. Thousands of tests were conducted with each test randomly varying threat parameters and hit locations in order to capture the chaotic nature of random unknowns, thus providing a probabilistically determined assessment of occurrences similar to real world threat events. Structural, Mobility, Damage Control, and Self Defense mission areas with limited inherent survivability are identified and expert recommendations proposed based on analysis of initial damage in addition to “through time” performance results and from expert design review. In cases where design recommendations are not feasible or difficult to implement, then the recommendations made focus in improving operational survivability through crew actions and training.
