  J.X. Wen¹, M. Marono², P. Moretto³, E.-A. Reinecke⁴, P. Sathiah⁵, E. Studer⁶, E. Vyazmina⁷ and D. Melideo⁸ - ¹University of Surrey, ²Research Centre for Energy, Environment and Technology (CIEMAT), ³European Commission, Joint Research Centre (JRC), ⁴ForschungszentrumJuelich GmbH, ⁵Shell, ⁶CEA, ⁷Air Liquide, ⁸Università di Pisa
  This paper provides an overview of the European Hydrogen Incidents and Accidents Database (HIAD 2.0) and describes the processes followed by the authors to derive lessons learned and formulate recommendations. Lessons learned have been categorised according to system design, system manufacturing, installation and modification as well as human factors and emergency response. The recommendations provided consider operational modes, industrial sectors and human factors.
• EMBlast: A software for calculating blast loads on structures from the detonation of energetic materials
  S.C. Angelides^1,2, B.A. Burgan¹, C. Kyprianou¹, S.E. Rigby², A. Tyas² - ¹Steel Construction Institute, ²University of Sheffield
  Current software for calculating blast loads on structures from the detonation of energetic materials tend to be either complex, expensive CFD software or restricted fast-running software originating from the military and lacking in documentation. This paper presents methods for rapidly and accurately predicting blast loads on structures, which have been implemented in the EMBlast software. This paper particularly focusses on the prediction of free-field and reflected pressure-time histories.
• Modelling blast wave clearing using Load_Blast_Clearing: Part I - verification and validation
  L. Schwer¹, S. Rigby² and T. Slavik³ - ¹Schwer Engineering & Consulting Services, ²University of Sheffield, ³Ansys, Inc.
  The implementation of an engineering model of air blast in LS-DYNA, known by the keyword Load_Blast, has been a useful feature. Several improvements were then made under the keyword Load_Blast_Enhanced and more recently, additional improvements have been made via the new keyword Load_Blast_Clearing. This paper introduces the new keyword Load_Blast_Clearing, provides some verification and validation, and explores a novel application involving oblique blast waves.
• Consequence assessment considerations for toxic natural gas dispersion modelling
  S.R. Nair¹, N.O. Ogbeifun¹, J.X. Wen² - ¹Chevron, ²University of Surrey
  This paper discusses the results from consequence modelling studies performed for a selected set of toxic natural gas release events in relation to onshore pipeline transfer. The study analyses the modelling inputs and parameters, and determines the key release source terms and atmospheric parameters that impact the estimation of hazardous zones.
