In this research, MOL and NMRI will jointly develop and verify the digital twin model of two-cycle main diesel engine by using operational data collected from MOL-operated vessels in service, aiming to enable visualization of the main engine's operational status.

The research has as a goal to establish a visual twin model that would identify and quantify the status of the main engine, which is difficult to grasp during ship operation and to enhance the accuracy of estimates for the engine's operating state and degree of degradation over time.

The project contributes to the establishment of Condition Based Maintenance (CBM), while improving the accuracy of diagnosis technology for the engine failure state. Moreover, it provides observers to more accurately grasp the main engine's performance during its transient state in difficult weather conditions, leading to optimal and safe engine operation, like prevention of torque-rich conditions and suppression of torque variation.
