- Abstract
- Second-order motion characteristics of a semisubmersible are investigated in regular waves. Higherorder boundary element method in frequency domain and finite element method in time-domain are applied to numerical analysis of nonlinear hydrodynamic force and motion characteristics of semi-submersibles in scope of potential theory. Various aspects of nonlinear effects on heave and roll of a semi-submersible were numerically investigated and some selected cases were compared with model test data. ？ 2010 COPPE/UFRJ.
