Abstract
The non-linearities in wave- and slamming-induced rigid-body
motions and structural responses of ships such as heave, pitch and
vertical bending moments are consistently investigated based on a
rational time-domain strip method. A hydrodynamic model for
predicting sectional green water force is also outlined for the
investigation of the effect of green watrer oads on the globalhull
girder bending moment. The computational results based on the
non-linear time-domain strip theory are compared with those based
on the fully non-linear 3-D panel method SWAN-DNW and other
published results.From the rather extensive computations and
comparisons, it is found that non-linear effects are significant
in head and bow waes in the motion-wave resonant region for both
heave and pitch motions, bow accelerations and vertical bending
moments for two container ships considered, whereas not
significant for a VLCC. The non-linearities in motions and
structural loads of conventional monohull ships seem well
predicted by the present non-linear strip theory.
