This deliverable focuses on the development of a Digital Twin (DT) for hybrid vessels, enabling simulation, optimization, and verification of energy management strategies and onboard electric grids. The DT serves as a powerful tool to enhance vessel efficiency, reduce emissions, and support the transition toward sustainable maritime operations.
The document details the methodology and implementation of the DT framework, covering key components such as the Energy Management System (EMS), Power Management System (PMS), and physical layer models. It outlines the assumptions, numerical models, and integration steps required to create a reliable virtual representation of two DEMO vessels (Gunnerus and Ataturk). Additionally, it provides an analysis of different operational scenarios, comparing traditional diesel-based operation
with hybrid and fully electric modes.
Simulation results demonstrate potential energy savings and emission reductions achieved through strategies for power distribution and optimal energy storage configuration. The validation of the DT against benchmark scenarios confirms the added value of integrating batteries and intelligent control system on board vessels. The conclusions highlight the importance of DT-based optimization and set the stage for further enhancements in subsequent project phases, including real-time data integration
and onboard implementation.
In fact, D2.5 presents the work and outcomes of the first phase of DT development, focusing on identifying requirements, developing and integrating numerical models, and conducting early simulations and validations.
In the subsequent Work Packages (WPs), the DT will undergo further refinement, expansion, calibration, and validation to enhance its accuracy and functionalities. For instance, in T4.2, all actual control functions, including Battery Management System (BMS), PMS, and EMS, will be fully identified, along with the communication between them and their interactions with power components. This will establish a clear functional link between control algorithms and physical hardware. Besides, in T4.3 and T4.5, integration testing will focus on component interoperability and the validation of key control functions. These tests will provide crucial feedback for fine-tuning the DT, ensuring it accurately reflects real-world vessel operations. Finally, only in T5.2 the necessary digital solutions will be identified and implemented on board, such as data acquisition systems, logging, and real-time communication. This step is essential for transforming the simulation framework developed in T2.5 into a true, operational Digital Twin, enabling it to be fed with real-time data to generate control recommendations, predictive insights,
and system optimizations dynamically.
Through these progressive enhancements, the DT will evolve from a validated simulation model to a fully integrated, real-time decision-support system, improving vessel efficiency, safety, and sustainability.
