RINA organised a Hazard Identification (HAZID) study for the preliminary risk assessment of WP8. This is the first step of the risk assessment and in the next steps a quantitative risk assessment study as well as a HAZOP study will take place. The workshop was a 3 days event (11-13th of June) that took place in Trieste, Italy. We were hosted by the University of Trieste (UNITS). In total there were 25 participants including members of the consortium as well as External Advisory Board members.
The scope of the Hazard Identification Study was:
-to identify the risks of the membrane type LH2 cargo containment system design (primary barrier, secondary barrier and insulation), considering also the ship integration and the main handling, distribution and monitoring subsystems.
-to ensure that any risks arising are eliminated-or in the cases that this is not possible to ensure that adequate safety barriers/requirements are in place to mitigate these risks.
The HAZID was based on the work carried out in Work Packages (WP2 – LH2 Containment Implementation Plan and Evaluation Criteria, WP3 – Conceptual Engineering Design for the LH2 Tank Storage & Scalability Scenarios and WP4 – Preliminary Integrated Ship Design for an Innovative LH2 Carrier). Before the workshop an extensive list of hazards and safeguards for the different system nodes was developed by RINA and University of Strathclyde. The hazards were mostly based on the CCC9 WP6 (2023) – ‘Revision of the Interim Recommendations for Carriage of Liquefied Hydrogen in Bulk’.
A list of actions was identified for relevant project partners to eliminate and mitigate potential risks. The findings of this study will serve as input for the subsequent steps in the LH2CRAFT design process.
