This paper presents a novel approach for assessing the effectiveness of wind propulsion systems through an integrated simulation framework combining a four degrees of freedom (4 DoF) Performance Prediction Program (PPP)/Velocity Prediction Program (VPP) with route-based voyage simulations incorporating environmental conditions and conventional engine usage. The methodology leverages the SAIL module within an in-house software environment, which calculates aerodynamic forces on individual wind propulsion elements—such as Dynarigs—using experimentally derived wind tunnel force coefficients. These aerodynamic forces are integrated into the route simulation tool, enabling voyage simulations that include detailed weather data, ocean currents, and conventional engine power. By simulating a defined route with given environmental inputs, the framework computes the vessel’s optimal equilibrium speed and propulsion power distribution. The WPS sail area is adjusted dynamically in response to wind speed and direction to maximize thrust contribution while ensuring safe vessel operation. The simulation iteratively balances wind propulsion input with conventional engine output to maintain target speeds along the route, facilitating direct comparisons of fuel consumption and emissions with and without wind assistance. Furthermore, the modular nature of the simulation allows for future incorporation of additional factors such as sail maneuvers and route optimization.
