ABS, HD KSOE and Siemens Sign MOU to Develop Digital Twin Technology for Ammonia Safety

ABS, HD Korea Shipbuilding & Offshore Engineering (HD KSOE), and Siemens have signed a memorandum of understanding (MOU) to collaborate on digital twin technology for assessing the safety of ammonia-fueled vessels. The agreement, announced at Gastech 2026, aims to combine computational fluid dynamics (CFD) analysis with digital twin technology to rapidly predict ammonia dispersion behavior in the event of a leak.

By pairing CFD analysis with digital twin technology, the project will give designers a faster, more rigorous way to understand leak behavior, according to Patrick Ryan, ABS Senior Vice President and Chief Technology Officer. HD KSOE will develop ammonia safety systems and lead related experimental research, while Siemens will provide simulation analysis and digital twin technology.

ABS will supply a safety assessment methodology built around digital twins. The collaboration is seen as a significant step forward in ensuring the safety and engineering reliability of next-generation vessels, as the industry continues to evaluate alternative fuels.
