In recent years, Very Large Floating Structures (VLFS) such as floating airport have been planned for effective utilization of ocean space. The VLFS is some times sheltered by breakwater depending on the situation. This paper presents an effective scheme for calculating the wave-induced hydroelastic response of VLFS including the effect of breakwater. This part I report, at first presents an effective calculation method of the diffracted wave field due to the existence of breakwater. And then it shows an approximate calculation method of the response of VLFS in that deformed wave field by the breakwater. In this method the mutual interaction between breakwater and floating structure is neglected. But by virtue of this, the computation time is very short. The numerical results have shown fairly good agreement with the other existing numerical ones. The accurate calculation method of the response including the effect of the interaction will be reported in the subsequent paper.
