The motion and tension responses of a moored system due to combined wind-wavecurrent action are numerically studied.The mathematical model is composed of 3D mooring-line static model and floating-body motion model in frequency domain. In the study,the stiffness of a moored system and the hydrodynamic coefficients of a floating-body are calculated separately by finite difference method(FDM) and the Green function method.Based on coupling the above methods,the response and tension variation of the moored system is analyzed.As a numerical example,a moored semi-submerged platform is adopted.The calculation results show that the method is reliable and feasible for predicting the moored system.
