| Abstract: | By using the theories on Stokes multicolored water waves and taking two layer ocean as a basic model of stratified ocean,the paper analyzes the problems related to the effects of nonlinear water wave on offshore structures. A mathematical expression is presented to describe second order wave radiation conditions. Using integral principle,an analytical integral solution is given to evaluate second order scattered wave loads on general vertical circular cylinders in two layer ocean,and special recurrence formulas for infinite integrals over free and stratified surfaces are derived. |
