Abstract

The maritime sector is undergoing a significant transformation to meet global emission targets. Hydrogen-diesel dual-fuel (HDDF) engines are considered a promising solution for the transition to low-carbon shipping. This study examines HDDF marine engine systems from a risk and safety perspective. The Hazard Identification (HAZID) methodology was used to identify potential hazards during the design phase. The system was analysed by an expert panel. The findings revealed risks in critical components such as storage, boil-off gas (BOG) management, and hydrogen injectors. Existing safety measures are evaluated, and further improvements are recommended. This study provides a safety-oriented roadmap and a comprehensive database, useful for future risk analyses.
