Following the completion of the first deliverable of Task 7.2, the Preliminary Risk Evaluation Report (Initial Version) in November 2024, and the subsequent collection of relevant data on the primary risks associated with sustainable alternative fuels (Ammonia, Hydrogen, and Liquid Organic Carriers), the next step involved consolidating this information into a structured worksheet. This worksheet served as the benchmark for the Hazard Identification (HAZID) workshop. The focus of the workshop was the demonstrator—a bulk carrier powered by compressed hydrogen gas.
To ensure a systematic and efficient HAZID process, the overall system was divided into six distinct system nodes: Bunkering Station, Fuel Storage, Fuel Supply Unit, Hydrogen Generator Set (Hydro Genset), Gas and Vent System, and Power Take-In/Power Take-Out Systems. The worksheet documented the causes and consequences of each potential hazard, the corresponding safeguards, and the risk levels associated with each scenario.
From February 10–12, 2025, the SAFeCRAFT consortium convened in Athens for the HAZID Workshop, which was led by the University of Strathclyde and hosted by the School of Naval Architecture and Marine Engineering – NTUA. During the workshop, approximately 205 hazards were identified, and additional risk mitigation measures and design modifications were proposed to enhance safety to an acceptable level.
At the second General Assembly (GA) meeting held in Patras on February 13–14, 2025, the key findings of the workshop were presented to consortium members who had not participated in the HAZID workshop to keep them informed of the task’s progress.
The next milestone, Deliverable 7.3: Preliminary Risk Evaluation Report (Final Version), is scheduled for completion in July 2025. This report will incorporate the action list derived from the HAZID findings and the final worksheet, including design recommendations. Additionally, this deliverable will provide critical feedback for the design procedures of the demonstrator (Tasks 4.1 and 4.2).
Finally, the consortium should deliberate on whether to extend HAZID workshops to include desktop studies as part of the broader risk assessment process.
