Aiming at the crash stopping motion simulation of azimuth tug, equipped with double ducted controllable pitch propellers, the stopping motion mathematical model of the azimuth tug was established based on separated modelling. By using the Target’s residual resistance curves, the residual resistance modulus was obtained at different Froude number. The resistance model for both high and low speed was proposed. By the JD7704 ducted Ka4-70 propeller curves after correction and C4-40 propeller curves derived from Netherlands Ship Model Basin, the thrust coefficient of different hydrodynamic pitch angle and pitch ratio was conducted. The thrust model applying to actual operation condition of ducted controllable pitch propeller was established. Simulation results show that the proposed model can meet the accuracy requirements of crash stopping motion for azimuth stern drive tug on simulator.
