New Standards for Digital Twin Testing Developed by DNV

Norway-based classification society DNV has entered into a memorandum of understanding with South Korea’s HD Hyundai Mipo (HMD) and HD Korea Shipbuilding & Offshore Engineering (KSOE) to establish new standards for utilizing digital twins in testing electric propulsion systems. This collaboration aims to enhance ship safety and efficiency by developing criteria and procedures for testing electric-powered vessels through digital twin-based methods. By integrating hardware-in-the-loop (HiL) testing via digital twins of various systems, integration tests can be conducted earlier and more comprehensively to address complex vessel system issues.

The project focuses on verifying digital assets to ensure the accuracy of tests and facilitate the integration process. By utilizing DNV-verified digital assets, the reliability of testing is enhanced, especially when testing systems from multiple suppliers together with consistent requirements and HiL test procedures. The goal is to establish clear and practical digital twin-based testing procedures and standards to encourage industry participation and ensure reliable results, ultimately safeguarding the performance and safety of ship systems.

Furthermore, the collaboration aims to maintain digital assets throughout the vessel’s life-cycle to maximize their long-term value. Verified assets can be used in a “plug-and-play” manner for introducing different systems into the simulation space or updating them over time. This initiative aligns with DNV’s Data-driven Verification (DDV) notation, which ensures the reliable performance of complex systems. DNV had previously granted approval in principle (AiP) to HD Hyundai for its cloud-based integrated Hyundai Intelligent Digital Twin Ship (HiDTS) system and has been collaborating with HD KSOE on data-driven verification (DDV) of digital twin technologies since 2022.
