Evaluation of oscillatory forces on free-floating ship of spherical or ellipsoidal hull at zero forward speed in head sea for surge, heave, and pitch, dependencies of added mass, added moment of inertia, and damping coefficients on frequency of forced oscillation as well as on frequency of oncoming wave are shown; equation of motion governing oscillation of freely floating ship is obtained through synthesis of hydrodynamic forces in radiation and diffraction problems; frequency dependence of two pertinent parameters occurring in equation of motion, amplitude ratio and phase lag between ship motion and wave motion, are also established.
