The purpose of this brief essay is to put into perspective ongoing research involving the simulation of intact ships in waves and wind, including conditions leading to capsize. A major challenge lies in the conversion of theoretical knowledge and numerical models to practical and useful information. One necessary condition for such knowledge transfer to be successful is a strong link between the research world and the "real" world, like ship operators and regulatory bodies. In conjunction with the present Cooperative Research Navies project on Dynamic Stability, work has been carried out with the following objectives: modeling of capsize physics and risk analysis, development of "rational" design criteria, development of decision support tools (ship operation) improvement of training/education, The numerical simulation of ship capsizing and broaching plays a central role in this process. To establish confidence levels in the time domain tool developed in recent years, Quality Assurance is essential. This includes the development of QA procedures, benchmark tests, and validation through model tests and full scale data. Without any further elaboration, I would like to mention that research is carried out along similar lines for damaged ships within the same navy framework. This work relies heavily on the methods and procedures developed for intact ships, as discussed below.
