This paper deals with the wave diffraction/radiation problems of multiple floating bodies in regular waves. For the analysis of hydrodynamic force of diffraction/radiation problems, 3-dimensional eigenfunction expansion method is applied and numerical calculation code is developed. This paper describes detail of the 3-dimensional eigenfunction expansion method and the numerical results of various hydrodynamic forces and motions for the case of two adjacent floating bodies. These results will be the numerical examples of the commentary paper written by the same author. This paper also shows the irregular frequency phenomena appear in the case of 3-dimensional eigenfunction expansion method and describes its elimination method. Finally, the property of radiation waves due to the impulse response of multiple floating bodies is discussed and experimental estimation method of motion response amplitude operator without wave generator is shown as an appendix.
