The second-order motion characteristics of a semi-submersible are investigated in regular waves. A higherorder boundary element method in a frequency domain and a finite element method in a time-domain were applied to the numerical analysis of the nonlinear hydrodynamic force and motion characteristics of semisubmersibles in view point of potential flow. Various aspects of nonlinear effects on the heave and roll of a semisubmersible were numerically investigated and some selected cases were
