..., and numerical predictions of the radiation and excitation forces are given to explore unique aspects of the problem. Symmetric and asymmetric numerical heave, roll, and pitch RAOs for a generic naval frigate are compared to third-party model test data. It is found that asymmetry can have marked effects...

... shown to provide reasonably good approximations of a ship s motions in heave and pitch. However, these methods do not consider the hogging and sagging conditions of a hull separately, yielding simplified dynamic bending moment predictions that are often unsatisfactory. Physical measurements show...

... in longitudinal waves (head seas) is introduced. The discussion includes a treatment of the rigid-body dynamics behind coupled roll and pitch motions. Simplified non-linearly coupled roll-heave-pitch differential equations of motion including inertial, damping, and stiffness terms are developed. Direct...
