| Abstract | Ensuring the safe and efficient operation of ships requires a reliable performance evaluation. However, conducting such evaluations through field tests is often impractical due to high costs, time constraints, and environmental limitations. To address these challenges, SILS (Software-in-the-Loop Simulation) has emerged as an effective alternative. SILS is a simulation-based testing approach in which a system’s software components are evaluated within a virtual environment that replicates real-world conditions. It enables repeatable, cost-effective, and early-stage validation of system performance. This study proposes a method for ship modeling in a virtual environment for SILS-based collision avoidance simulation. To enhance the realism of the simulation, essential hardware characteristics of a ship—such as engine time delay and dynamic response—were incorporated into a virtual ship model, as they are critical for accurately representing the real-world behavior of the propulsion system. Furthermore, the hydrodynamic behavior of a ship was modeled using the equations of motion for a surface ship. By integrating both hardware and hydrodynamic dynamics, the modeling method of a virtual ship accurately reflects the actual performance of ship propulsion systems under realistic operating conditions. A virtual ship model generated from the proposed method was implemented within a SILS framework and applied to a range of collision avoidance scenarios involving various encounter conditions. Simulation results showed that the proposed method effectively replicated the dynamic responses of an actual ship and was capable of performing appropriate collision avoidance maneuvers. It could enable reliable and efficient evaluation of collision avoidance systems within a controlled and repeatable virtual environment. Moreover, it will be significantly able to reduce reliance on costly and limited field testing while maintaining a high level of realism and flexibility across a wide range of simulation scenarios. |
