WEBINAR DETAILS

We are pleased to confirm our next FABIG Lunchtime Webinar 'Upgrade of ISO Containers for Fire & Blast Resistance for Use in Hydrogen Process Facilities' presented by Robert Brewerton from Inoventech on Wednesday 24th November 2021 at 13.00 GMT.

For additional information and registration, please go to the Events section of the website.

 

Abstract:

Many providers of small hydrogen process units are basing designs on converted ISO shipping containers or bespoke modules fitting those dimensions. The 2018 GexCon HYSEA project was an extensive pre-normative 60 explosion test programme involving 20ft ISO containers with varying degrees of internal congestion, vent area and gas concentration, always with quiescent homogeneous clouds. Results analysis found that the collapse strength of vented shipping containers is around 0.3 to 0.35 bar, with 5 containers destroyed during the test series.

Practical hydrogen applications involve higher congestion and gas turbulence than tested due to high pressure leaks, so that substantially higher peak pressures can be expected in practice. The industry prefers the taller “highcube” containers in place of the standard height containers used in tests which would reduce explosion resistance.

This webinar will look at strengthening schemes, more efficient (faster) roof venting, which is most important for reducing peak pressures and shortening impulse durations, and dealing with doors. Proposals will be based on ISO 19880 part 1 2020 and will advocate analysis methodologies.

Additional mitigation methods will be considered: congestion reduction, venting doors, dealing with thermal insulation, fire, snow, security and unignited leaks. Site layout implications for explosion and fire will be discussed including design of free-standing blastwalls and canopies over refuelling vehicles to enable reduced safety distances and improved inter-modular high-pressure piping arrangements.

New worldwide environmental goals involve a “circular economy”, implying amongst other things that process containers have to be able to be brought back from remote regions into areas of available technical expertise for maintenance and then returned quickly. This means they have to fully comply with rules governing transport of containers both by land and sea. Current vented ISO modules do not comply, but proposed designs will. The webinar will end with recommendations for follow-on validation and for improvements to current industry guidance and land use planning.

 

FABIG WEBINAR SERIES

We are pleased to confirm that we will continue to organise Lunchtime Webinars on a monthly basis in the long term. As such, we are always looking for interesting presentations for our Lunchtime Webinar Series, so please do not hesitate to contact us at fabig@steel-sci.com if you or one of your colleagues would like to present at a future FABIG Webinar.

Take care and stay safe,
