Digital twins developed to test electric propulsion vessels
A consortium in South Korea is setting new standards for using digital twins to test electric propulsion systems
HD Hyundai Mipo (HMD) and HD Korea Shipbuilding & Offshore Engineering (KSOE) have signed a memorandum of understanding (MoU) with class society DNV to develop digital twins, and procedures and standards for testing electric propulsion installed in tugs, ferries and workboats.
Digital twins will also be used to model and analyse electric-powered vessels to verify and safeguard the performance and safety of onboard systems.
DNV said this collaborative project “aims to resolve issues related to the integration of highly complex vessel systems for electric propulsion.”
Digital twins will be used in conjunction with hardware-in-the-loop testing of the different systems to undertake integration tests earlier in the process on a much broader level.
“Through this technical collaboration, we aim to establish clear and practical digital twin-based testing procedures and standards,” said HD Hyundai Mipo head of quality management, Kitae Kim. “These can foster broader industry participation and ensure the reliability of results. In doing so, we hope to safeguard the performance and safety of ship systems and lead in building a digital twin ecosystem for the shipbuilding industry.”
When systems from multiple suppliers are tested together, having the same requirements and HiL test procedures ensures the reliability of the testing.
“We have proactively developed and implemented digital twin technology, including HiL, to safeguard the performance and quality of vessels, achieving advancements in virtual commissioning technology,” said KSOE head of the electrification centre and the Digital Technology Research Lab, Byoung Hun Kwon. “This collaboration marks a pivotal milestone, uniting HD Hyundai Mipo, HD KSOE and DNV to drive digital innovation in the shipbuilding and marine industry.”
DNV will increase confidence in digital assets through verification and facilitate the integration process between equipment and manufacturers.
“By adopting digital twin-based testing for complex systems, we are working together to shape the future of maritime operations and set new industry standards for safety and performance,” said DNV Maritime head of approval in South Korea, Andreas Kristoffersen.
This MoU project will focus on maintaining the digital assets throughout the lifecycle of a vessel to maximise its long-term value and operational performance. With verified assets, component models could also be used in a plug-and-play manner as different systems are introduced into the simulation space or updated over time.
This initiative is aligned with DNV’s data-driven verification (DDV) notation, which the class society developed to ensure reliable performance of complex systems.
