Navalprogetti Srl proudly took part in ATENA NAV 2025, held from July 10 to 12, 2025, in Messina, Italy. Organized by ATENA (Associazione Italiana di Tecnica Navale), this prestigious biennial conference gathers professionals, academics, and industry leaders to explore cutting-edge developments in naval architecture, marine engineering, and sustainable ship design.
This year’s edition focused on the future of maritime technologies, particularly in the field of decarbonization, hydrogen-based propulsion, and risk management in novel ship systems. The event served as an ideal platform for Navalprogetti to present two scientific contributions under the European sHYpS project — a key initiative dedicated to enabling zero-emission hydrogen-powered cruise vessels.
Paper 1: Design Safety Assessment for Liquid Hydrogen Systems
On the first day of the conference, Eng. Irene Lavagnini, R&D Manager at Navalprogetti, presented the paper titled:
“Design Safety Assessment for Liquid Hydrogen Systems on Board Cruise Ships through a Risk-Based Approach”
Authors: I. Lavagnini, F. Rezzante, P. Busetto, F. Cadenaro, M. Roiaz, G. Sancin, E. Russian
The research outlines a structured quantitative and qualitative safety assessment methodology for the integration of liquid hydrogen (LH2) systems aboard large passenger vessels. By applying a risk-based design approach, the study addresses potential failure modes, critical safety zones, and operational risk mitigation strategies.
This work reflects Navalprogetti’s strong focus on designing safe, innovative, and sustainable solutions in the context of the energy transition in the maritime sector.
Paper 2: Quantitative Risk Assessment of Hydrogen Tank Swap Operations
During the second day of NAV 2025, PhD candidate Elia Russian, representing Navalprogetti, delivered a presentation on:
“Quantitative Risk Assessment: Frequency Analysis of a Liquid Hydrogen Tank Container Swap Operation on a Passenger Ship”
Authors: E. Russian, I. Lavagnini, F. Rezzante, R. Taccani
This paper dives into the quantitative risk assessment (QRA) of a hydrogen bunkering operation, specifically analyzing the frequency of accidental events during the tank container swap process. The study contributes to the safety validation of novel fueling operations for hydrogen-powered ships, an essential aspect of future green maritime logistics.
Navalprogetti’s Role in the sHYpS Project and Future Outlook
These contributions are part of Navalprogetti’s broader involvement in the EU-funded sHYpS project, which aims to develop and demonstrate safe, scalable liquid hydrogen technologies for maritime applications. As a technical leader in system integration and safety assessment, Navalprogetti continues to play a key role in enabling the next generation of zero-emission cruise ships.
By participating in ATENA NAV 2025, Navalprogetti reaffirms its commitment to research-driven innovation, cross-sector collaboration, and climate-conscious ship design. Our team is proud to be at the forefront of hydrogen technology adoption in the maritime industry.
