Disclosed is a dynamic positioning maintenance model test system for a polar environment, which is capable of performing a model vessel test for evaluating the dynamic positioning performance of a polar vessel in polar environment conditions. The dynamic positioning maintenance model test system for a polar environment comprises: an icy water tank which reproduces conditions of the polar sea and the frozen ice in the polar sea; a model vessel which sails freely in the icy water tank; a tow carriage which is connected to the model vessel and is provided to tow the model vessel; a vision camera which is installed on the tow carriage to point the model vessel and is provided to capture the movement of the model vessel in real-time; a thruster which is mounted on the model vessel and is provided to generate thrust for the model vessel to navigate freely in the icy water tank; a measuring instrument which measures a 6 degrees-of-freedom motion of the model vessel using a motion image of the model vessel, acquired through the vision camera; and a controller which calculates force required for the model vessel to be maintained in a preset position using motion data from the model vessel, calculated according to the measurement of the 6 degrees-of-freedom motion, and calculates the thrust of the thruster according to the calculated force so as to control the thrust of the thruster.
