A particular form is selected for numerical applications, where the double integral of the Green function is transformed into the single one and the oscillation characteristics for integrands in the specific computation domain are treated numerically. A comparison of calculated examples with published data is given and it shows that the numerical simulation is satisfactory and the accuracy is adequate to engineering application.展开更多

As an example a special calculation result is given including the analysis of wave parameters for the data of the North Atlantic Basin and the computation of motion and load encountered by two container ships CSLR and CSBV in different loading conditions. All computation results are satisfactory compared with corresponding design results.展开更多
