Disclosed is an optimal navigation system of a ship. An optimal navigation system of a ship according to the present invention comprises: a propulsion engine which is connected through a propeller and a propulsion shaft to generate propulsion of the ship; a power transmission unit which is connected to the propulsion shaft to produce power using a part of power supplied from the propulsion engine to a propeller; and a control unit which determines a PTO value of the power transmission unit by electric load analysis (ELA) of the ship considering a load factor of the electric equipment inside the ship, collects and analyzes data on sea conditions, calculates an optimal speed in a state in which the propulsion engine is operating with an optimal output value calculated based on a minimum fuel consumption rate (SFOC), recommends the optimal speed to the bridge maneuvering system (BMS), and controls the engaging or disengaging operation of the power transmission unit. The propulsion engine can operate at the optimum output, such that optimum efficiency navigation is possible with the minimum fuel consumption rate.

    선박의 최적운항시스템이 개시된다. 본 발명에 따른 선박의 최적운항시스템은, 프로펠러와 추진축을 통해 연결되어 선박의 추진력을 발생시키는 추진엔진; 추진축에 연결되어 추진엔진으로부터 프로펠러로 공급되는 동력의 일부를 이용하여 전력을 생산하는 동력전달부; 및 선내 전장 장비들의 Load Factor를 고려한 선박의 ELA(Electric Load Analysis)를 분석하여 동력전달부의 PTO 값을 결정하고, 해상 상황에 대한 데이터를 수집 및 분석하여 추진엔진이 최소 연료소비율(SFOC)을 기준으로 산정된 최적 출력 값으로 운전중인 상태에서의 최적의 속도를 계산하여 BMS(Bridge Manoeuvring System)에 추천하며, 동력전달부의 연동 또는 연동해제 동작을 제어하는 제어부를 포함하여, 추진엔진이 최적 출력으로 동작이 가능함에 따라 최소의 연료소비율로 최적 효율 운항이 가능한 효과가 있다.
