The complexity operating conditions of marine propulsion system significantly determines the total performance of a vessel. Chebyshev polynomial which possesses the ability to early identify hydrodynamic properties of marine propeller satisfies the precision need to model the propeller characteristic across four quadrants hence useful for dynamical modeling of ship manoeuvring in all-round operations. Determination of propeller thrust and torque coefficients of propeller B-4.58 across four quadrants is performed using the scheme and is compared with the result from experimental tank test. Investigation which reveals that the result generated is valid for first quadrant deduced that the scheme is practically applicable. The coefficients were then used in a thrust and torque estimation scheme and further applied in a ship manoeuvring simulation model. Simulation for crash stopping condition which fully utilised four quadrants of propeller operations was performed and the results were analysed.
