Abstract
A sea state estimation device includes a time history memory which stores a time history of ship motion data relating to a rolling angle, a pitching angle and a heaving displacement; a hull condition data calculator which calculates current hull condition data of the hull based on the time history of the ship motion data stored in the time history memory; a cross spectra calculator which calculates cross spectra of respective ship motions; a hull response function calculator which calculates a hull response function based on the hull condition data calculated by the hull condition data calculator; and a sea state estimator which estimates a sea state in sea on which the hull is running based on the cross spectra of the respective ship motions calculated by the cross spectra calculator and the hull response function calculated by the hull response function calculator.
