We are pleased to inform you that the 83^rd edition of the FABIG Newsletter is now available on the FABIG website.

FABIG Members are able to download Issue 083 from the Technical Newsletters section of the website (once logged-in) whilst non-Members of FABIG are able to purchase it.

This issue comprises the following:

• Editorial: 'Hydrogen: A key ingredient in the acceleration of the energy transition?'
  P. Hoorelbeke - TotalEnergies
• Vented shipping containers and barrier walls for hydrogen facilities
  R. Brewerton - Inoventech
  This article considers the main design issues involved in the conversion of vented ISO shipping containers for use in hydrogen process facilities. Container strengthening schemes and the fitting of faster opening vent panels and doors are described in order to reduce explosion pressures and the risk of harmful projectiles. Fire resistance, safety barriers as well as other functional requirements are also covered in this article.
• Explosive phase transition in LH₂
  K. Vaagsaether, P.M. Hansen, D. Bjerketvedt - University of South-Eastern Norway
  This paper describes two models for analysing and simulating the physical effects of explosive phase transition of liquid hydrogen (LH₂), also known as cold BLEVE.
• A review of application of integral atmospheric jet dispersion model to flammable hazards: Is hazard distance at 0.5 LFL conservative?
  F. Tan¹, V. Tam² and D. G. Middleton³ - ¹BP, ²FABIG Steering Committee Member, ³Retired, formerly BP
  Integral atmospheric jet dispersion models are widely used to estimate flammable hazard distances, for design and for risk assessment. There is a widespread but erroneous belief that flammable distances from these models are conservative when flammable ranges are calculated using the 0.5 lower flammability limits (LFL) concentration threshold. This paper describes the assumptions and applicability of commonly used atmospheric dispersion models and provides suggestions for the appropriate use of these models and for further work on the extension of the flammability factor.
