Estimation of directional frequency transfer functions of floating offshore structures is important to estimate their behaviours in realistic short crested irregular waves (such waves are called as directional spectrum waves) Of course, there are some theoretical calculation methods for such directional response functions, but it seems that there are not so many experimental results confirming such theoretical ones. For that purpose, square basins are needed. In the first report, the authors showed the method of inverse estimation of directional transfer functions of a floating offshore structure only using results of a few experiments in directional spectrum waves in a long towing tank. In this paper, this method is improved for the estimation of wide range of directional response fuctions. The precisions of estimated directional frequency response functions are confirmed by experiments.
