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.

    본 발명은 운항선자료, 저항증가량 계산, 선체자세변화에 따른 동력해석 및 표준운항상태에서의 선속과 동력의 관계를 규정하여 표준운항상태에서의 연료소모율을 해석하는 운항선의 표준운항상태 연료소모율 해석 방법에 관한 것으로서, 파도, 바람, 수온, 조타각 및 표류각에 대한 정보를 이용하여 저항증가량을 계산하는 단계; 계산된 부가저항을 보정하고 이상적인 조건의 마력인 정수중마력을 계산하는 선속-동력 해석을 수행하는 단계; 배수량 및 트림 정보를 수신하여 이에 대한 보정을 수행하여 평수중 선속-동력 해석을 수행하는 선체자세변화 동력 해석 단계; 표준운항상태의 부가저항을 고려하여 표준운항상태 선속-동력 해석하는 단계; 및 연료소비율(Specific Fuel Oil Consumption curve ; SFOC curve)에서 계측된 제동마력값에 대응하는 연료소모율 값을 읽어 표준운항상태의 연료소모율을 계산하는 단계;를 포함하여 구성되어 표준운항상태에서의 연료소모율을 해석하여 보다 정확한 연료소모율을 예측할 수 있는 효과가 있다.
