Disclosed is a urea solution production system for a ship. In accordance with the present invention, the urea solution production system for a ship includes: a fresh water generator provided on a ship and generating fresh water from seawater; and a urea solution production part receiving the fresh water from the fresh water generator to produce a urea solution to be supplied to an SCR in the ship. The urea solution production part includes: a water softening filter receiving the fresh water from the fresh water generator to remove impurities therefrom; a water supply box receiving and storing ultrapure water, from which the impurities have been removed, from the water softening filter; and a bypass line supplying the fresh water to the water supply box by bypassing the water softening filter. As flow rates of the fresh water supplied to the water softening filter and the fresh water bypassed to the bypass line are controlled, at least one type of water among the ultrapure water and the fresh water is supplied to the water supply box for urea solution production. Therefore, the present invention is capable of reducing costs for maintenance.
