The present invention relates to a fuel consumption rate analysis method for a standard sailing condition of a vessel which defines power analysis in accordance with vessel data, resistant increase calculation, and a hull position change and a relationship between a ship velocity and power in a standard sailing condition to analyze a fuel consumption rate in the standard sailing condition. The fuel consumption rate analysis method for a standard sailing condition of a vessel comprises: a step of using information for a wave, a wind, a water temperature, a steering angle, and a drift angle to calculate a resistance increase; a step of performing ship velocity-power analysis of correcting calculated added resistance and calculating calm water horsepower which is horsepower under an ideal condition; a hull position change power analysis step of receiving a drainage amount and trim information to perform correction for the drainage amount and trim information to perform normal water ship velocity-power analysis; a step of considering added resistance in a standard sailing condition to perform standard sailing condition ship velocity-power analysis; and a step of reading a fuel consumption rate corresponding to a measured brake horsepower value from a specific fuel oil consumption (SFOC) curve to calculate a fuel consumption rate in the standard sailing condition. The fuel consumption rate in the standard sailing condition is analyzed to predict an accurate fuel consumption rate.
