To probabilistically estimate wave response of a vessel by using two-dimensional wave spectrum data by wave hindcast or parameters of short-term marine conditions derived by approximating a two-dimensional wave spectrum with a function model.SOLUTION: A wave response estimation method includes: a sea route information acquirement step for acquiring sea route information of a vessel including AIS data; a wave hindcast data acquirement step for obtaining wave hindcast data based on the sea route information; a short-term marine condition derivation step for deriving short-term marine conditions based on wave development probability by acquiring the wave development probability by application to a wave development frequency probability model based on the sea route information and the wave hindcast data; a two-dimensional wave spectrum derivation step for acquiring two-dimensional wave spectrum by applying the short-term marine conditions, the sea route information, and the wave hindcast data to a wave spectrum probability model; a response function derivation step for deriving response functions based on speed of the vessel taking into consideration the two-dimensional wave spectrum and waves; and a short-term prediction step for carrying out a short-term prediction by using the response function.SELECTED DRAWING: Figure 8
