Abstract
The singularity distribution method or the Green's function method is considered to be one of the most suitable methods for estimating motions of an arbitrary shape floating body. This is based on the integral of the Green's function and its derivative over the submerged surface of a floating body. For precise calculations of the integral, sophisticated numerical treatments are required, and the corresponding CPU-time may be very long.This paper deals with an elimination technique of CPU-time to calculate the Green's function of a floating body with a symmetrical shape. Appling it to a biaxial symmetrical floating body, CPU-time can be reduced to be the quarter in comparison with the ordinary calculation.
