This paper describes a simulation driven approach to the design of a shaft counter-rotating propeller (CRP) system for the next generation coaster vessel. The design workflow involves parametric CAD models of ship hull, propellers and rudder, and numerical tools of different fidelity levels which are employed in exploration studies, iterative elaboration of propeller design and final verification of ship's propulsion performance. It is demonstrated that, in the present case, with a wakeadapted CRP design one can achieve a power reduction of 8.5 to 9.0 % compared to the solution with a single propeller designed for the same conditions. In addition to propulsion characteristics, the paper also presents the analysis of unsteady loads on propeller blades and rudder, propeller-induced pressure pulses on the hull and radiated noise level, comparing the mentioned quantities between the CRP and single propeller designs.
