Nowadays, maritime transport is increasing significantly, and the probability of collisions between ships in densely populated region has increased. In this regard, improving the ship maneuvering performance has a significant impact directly on the economy and safety of navigation. Therefore, the study of maneuver parameters is considered as a mandatory issue in the process of designing a ship. In this study, first the validation of the results has been done for the KCS. The benchmark ship at froud number 0.201 was simulated in three degrees of freedom including: surge, heave and pitch and calm water conditions, then the results were compared by computational fluid dynamics. Validation was performed according to the ITTC Recommendation by three levels of gridding, and the value of numerical uncertainty was also estimated. Uncertainty less than 12% and numerical error respect to experimental less than 6% were extracted. A good match was presented between the numerical and laboratory results. A good match was presented between the numerical and laboratory results. The two-phase flow the Volume Of Fluid (VOF) method and the DES turbulence model were used to model the flow around the hull. The effect of propeller was induced by actuator disk method and based on flowchart in ship stern.
