| Abstract: | The capsizing for an offshore cargo ship in regular beam waves was studied by using the theory of safe basin.The single degree of freedom second order differential equation of nonlinear rolling motion was solved numerically in time domain by using the Adams-Bashforth method.The hydrodynamics in the used frequency domain were calculated based on3-D Green ' s integral equation method.The influences of potential damping,nonlinear viscous damping,wave heights and wave frequencies in regular beam waves on the safe basin were investigated. |
