Abstract
Excessive rolling is a common safety hazard to crew, equipment and cargo at sea, as well as a frequent and serious source of performance degradation. In this paper, the factors with primary influence on frigate rolling are studied parametrically using recently developed and validated prediction methods. Factors under study include displacement, key hull form parameters, bilge keel and rudder size, passive fins, metacentric height, roll moment of inertia, and active stabilization. For each ship configuration, predictions are made for an operationally meaningful range of speed and sea conditions. Results are presented in graphical and tabular forms whereby the effect of each parameter on rolling may be readily assessed.
