At-sea experiment using prot-type floating platform "POSEIDON" is now going on at Japan Sea. This paper describes the measuring technique and the estimating method of the directional wave spectra at sea. For the estimation of the directional wave spectra, various kinds of measuring devices and data analyzing methods have been proposed. In this experiment, the three wave probes arranged in a line array are used and the directional wave spectra are estimated by the maximum likelihood method (MLM). Then, the accuracy of MLM was examined by tank tests and numerical simulations. In this tank test, relative wave heights of floating structure models were also measured to estimate the directional wave spectra. The main results are as follows; 1) MLM has the high resolution and can detect progressive waves using only three wave probes arrenged in a line array. 2) The directional wave spectra can be also estimated from the relative wave heights of floating structure model.
