Abstract
Dynamic stability simulation tools developed by the Cooperative Research Navies have been used to investigate the relationship between a number of stability criteria and the probability of exceeding a critical roll angle. Multiple roll response time series for several ships in various seaway conditions are generated to provide the probabilities. This paper describes the investigation into the probability results themselves, as a precursor to regression against GZ curve parameters. Specifically, it examines the effects of modelling choices and of variation and range in the input control variables.
