Maneuverability is an important aspect of marine vehicle design. With the development and utilization of ocean resources, maritime transportation is becoming increasingly busy. Stopping ability has great effect on the safety of ship maneuvering for those large ships. Therefore, it is necessary to study the behavior of the ship during the stopping maneuver to ensure the safety of navigation. In this study, the stopping maneuver has been investigated directly and with interaction between the ship's hull and propeller, Reynolds Averaged Navier-Stokes (RANS) equations and Star-CCM+ commercial software. well-known vessel KVLCC2 have been selected to study the parameters of the stopping maneuver. In order to reach the design speed of the ship, the self-propulsion test has been carried out using a PI integral controller. Verification and validation of the results have been studied according to ITTC recommendations. By comparing the results obtained in the self-propulsion test as well as the stopping maneuver with some available experimental data, a good accuracy was obtained and the details of the flow parameters, including pressure distribution and wake pattern, were analyzed
