This FABIG Newsletter comprises the following:

• Editorial: 'Communicating our understanding of hydrogen fire & explosion hazards is key'
  M. Johnson - FABIG Steering Committee Member | DNV
• An innovative and comprehensive approach for the consequence analysis of liquid hydrogen vessel explosions
  F. Ustolin¹, N. Paltrinieri¹ and G. Landucci² - ¹NTNU, ²University of Pisa
  This paper presents a novel approach for the comprehensive assessment of the consequences of a LH2 BLEVE. Conventional empirical and theoretical models were used to model the BMW tests so as to investigate if such well-known methods (already validated for hydrocarbon BLEVE) are suitable for LH2 BLEVE. The most suitable models for the LH2 BLEVE consequence analysis were then selected and used in a blind prediction study to estimate the consequences of planned LH2 BLEVE experiments. For the first time, the presented approach covers all the identified typologies of BLEVE consequences for both small- and mid-scale LH2 accident scenarios.
• A critical review of the equivalent stoichiometric cloud model Q9 in gas explosion modelling
  V. Tam¹, F. Tan² and C. Savvides² - ¹University of Warwick, ²BP
  This paper reviews published data and describes additional assessment on the use of the equivalent stoichiometric cloud model Q9 in gas explosion modelling using the large-scale experimental dataset from Phase 3B of the Blast and Fire Engineering for Topside Structures (BFETS) joint industry project, which was designed to address this type of scenario.
• Outcomes of PRESLHY project on pre-normative research for the safe use of liquid hydrogen
  D. Cirrone - Ulster University
  This paper describes the PRESLHY project and its outcomes. The research carried out as part of the PRESLHY project included extensive experimental, theoretical and numerical studies addressing LH2 relevant phenomena: release and mixing, ignition and combustion. The outcomes of the project aim to enhance the state-of-the-art, develop validated predictive models and tools to determine hazard zones for LH2 technologies where they are inconsistent or over-conservative, provide guidelines for inherently safer design of LH2 infrastructure, and support the Standard Developing Organisations in improving current international standards.
• Book review: 'Process safety: An engineering discipline, by Dr. Pol Hoorelbeke'
  B. A. Burgan - The Steel Construction Institute (SCI)
  Whilst the common goals of Occupational Health and Safety at work (OHS) and process safety mean that they are inter-twined, they are very different disciplines. Although numerous textbooks deal with one or the other, this book brings into sharp contrast the differences, frameworks and drivers of OHS and process safety. It traces their development with a particular focus on the emergence of process safety as an engineering discipline, and brings the topics discussed to life with real examples as well as extensive illustrations emanating from the author’s vast experience in the oil & gas industry.
