Japanese shipping firm Mitsui O.S.K. Lines, Ltd. (MOL) President and CEO Junichiro Ikeda on Thursday (24 February) said it has signed a contract with the National Institute of Maritime, Port and Aviation Technology (MPAT), National Maritime Research Institute (NMRI) on joint research related to a digital twin model development of vessels’ main engine.
In this venture, MOL and NMRI agreed to 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, with the goal of enabling visualization of the main engine’s operational status.
The research aims to create a visual twin model that would identify and quantify the status of the main engine (amount of scavenging air, exhaust gas heat, etc.), which is difficult to grasp during ship operation and to increase 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.
Furthermore, it allows observers to more accurately grasp the main engine’s performance during its transient state in adverse weather conditions, leading to optimal and safe engine operation, such as prevention of torque-rich conditions and suppression of torque variation.
