On the computation of the survivability of navy vessels during the early design stage

A method is presented to determine the probability of survival of naval vessels in different scenarios of threat. The method is applicable especially during the early design phase in order to quickly assess the probability of survival of novel navy ship designs. It also makes it possible to identify and eliminate weaknesses in the design. This development follows the logic of threat-based naval ship design. The method is based on the regulations DMS 1030-1, DMS 1040-1, and DMS 0280 and demonstrates how these regulations can be used as ideal design tools in the early design phase. The method is implemented as a Monte Carlo simulation method within the E4 ship design system, and the methodological principles and their application to a sample design are explained in this article.
