The present invention is to propose a system capable of supplying an aqueous urea solution by reducing the installation cost and installation space of tanks and piping and related devices, and solving stratification. A system and method for producing an aqueous urea solution for a selective catalytic reactor (SCR) in a ship are disclosed. According to the present invention, the system for producing an aqueous urea solution for an SCR in a ship comprises: a urea supply tank provided on the ship and storing urea powder; a stirring tank in which the urea powder supplied from the urea supply tank and fresh water are mixed to generate an aqueous urea solution; an aqueous urea solution tank for receiving and storing the aqueous urea solution from the stirring tank, and supplying the aqueous urea solution to an SCR unit provided on the ship; a first liquid level sensor for detecting a liquid level inside the aqueous urea solution tank; and a control panel for controlling the generation of the aqueous urea solution in the stirring tank and transfer to the aqueous urea solution tank. The control panel may control the generation of the aqueous urea solution in the stirring tank according to a liquid level value in the aqueous urea solution tank detected by the first liquid level sensor.

    선박의 SCR용 요소수용액 제조 시스템 및 방법이 개시된다. 본 발명의 선박의 SCR용 요소수용액 제조 시스템은, 선박에 마련되며 요소 분말을 저장하는 요소공급탱크; 상기 요소공급탱크로부터 공급되는 상기 요소 분말과 청수가 혼합되어 요소수용액이 생성되는 교반탱크; 상기 교반탱크로부터 상기 요소수용액을 공급받아 저장하고, 상기 선박에 마련되는 선택적촉매환원장치부로 공급하는 요소수용액탱크; 상기 요소수용액탱크 내부의 액위를 감지하는 제1 액위센서; 및 상기 교반탱크에서의 상기 요소수용액 생성 및 상기 요소수용액탱크로의 이송을 제어하는 컨트롤패널을 포함하되, 상기 컨트롤패널에서는 상기 제1 액위센서에서 감지된 상기 요소수용액탱크 내부의 액위 값에 따라 상기 교반탱크에서의 상기 요소수용액 생성을 제어하는 것을 특징으로 한다.
