Each industry requires its own approach

Each industry is governed by different sets of regulations, and industry-specific knowledge is key to proper risk assessment. Such knowledge is essential for us to quickly understand your situation and challenges.

HYEX may support your projects from the early design stages by organising a design screening and help optimise system layout related to safety. The founder of HYEX, Olav Roald Hansen, has held many safety workshops (design screening, HAZID) with the purpose to identify risks and ways to mitigate or prevent. Given our broad understanding of the explanatory factors behind potential hazards, and expertise using the FLACS CFD consequence modelling software, we assess your risks efficiently.

Maritime industries

Zero emission fuels like hydrogen and ammonia, as well as most low emission fuels, are in the category of low flashpoint fuels and regulated by the IGF-code. The IGF-code requires a risk assessment to be performed, including an explosion assessment, to demonstrate that risks are equivalent to risks at modern, conventionally fuelled vessels. HYEX Safety supports such projects from the early design stages. We offer to organise design screening to help optimise system layout related to safety, contribute to HAZID-workshops to identify remaining hazards, and document the risk through an IGF risk assessment for evaluation by classification society and flag state administration. We also perform CFD-calculations to help define hazardous zones. Specifically, for bunkering sites, a risk assessment to define Safety area and Monitoring and Security area may be required, as for LNG per ISO 20519. Such assessments are highly relevant both for LH2 and for ammonia.

When required, we also perform:
box Simulations of exhaust pipe explosions (dual fuel engines) caused by misfiring.
Dispersion modelling of emission sources which, during certain wind conditions, may expose crew or passengers to substances, either flammable, harmful or with odours (e.g. hydrocarbons from tank vent, H2S, NOx, SO2, ammonia, sewage or benzene).
box Helideck studies per CAP437.
box Battery risk assessments, evaluating flammability and toxicity hazards from electrolytes.

Land-based infrastructure and industries

Safety assessments for any kind of hydrogen facilities, infrastructure and manufacturers are a speciality of HYEX Safety. Assessments may focus on design optimization to limit risk from hydrogen equipment, on workplace safety at hydrogen handling sites, or the evaluation of risk around a site to define risk contours for land planning purposes.

Upon request, we perform:
box Studies for sites handling other hazardous gases, including ammonia, LNG and other flammable hydrocarbons.
box Specialist CFD-studies for other gases, including a range of dispersion and explosion assessments.
box Accident/incident investigation support with detailed CFD-modelling

Petroleum industry

We offer a range of safety studies for the oil and gas industry. Our competitive edge is to perform challenging CFD-studies efficiently and accurate, including a range of ventilation, dispersion and explosion studies. Incident/accident investigation support and specialist studies using CFD will be priorities.
