Abstract:

This investigation initially provides roll motion predictions for two Strike Cruiser CSGN candidate hull forms, unstabilized and stabilized with a proposed bilge keel. Sizing computations for bilge keels and anti-roll fins were made for one hull form for various stabilized configurations. The configurations included a bilge keels only, b one fin pair with bilge keels forward, and c two fin pairs with bilge keels forward and in between the fins. Model experiments were conducted prior to the roll predictions to obtain realistic roll decay coefficients. Also, the performance of selected bilge keel and active fin stabilizer configurations was predicted for the range of ship operating speeds in various sea conditions.
