“…This result is in contrast to the conclusion of Birk for a similar study of the same accident [14]. In that work, in addition to initiating radiant exposure when the vessel was 50 per cent full, his model was unable to characterize the intermittent nature of the PRV and hence the correct mass discharge, conditions that could lead to a premature escalation of the wall temperature and thus earlier predicted failure.…”

“…The Von-Mises, or equivalent, stress (0.867 of the hoop stress) at the end of the PLGS_99 50-minute simulation suggests a factor of safety of at least 1.75 relative to the yield stress of the wall material at its maximum temperature and thus the vessel should not have failed.

This paper presents the failure analysis of a 1000 US gallon, horizontal, propane tank, which suddenly circumferentially separated at its central section while being radiantly heated. Thermo-hydraulic analyses of the tank and its contents, as well as nite element analysis of its possible thermal stress states coupled with other evidence show that the reasons for the catastrophe were complex-weld defects, low melting point ttings, placement, and re ghting-and all contributed to the failure. Recommendations are made in order to prevent future similar accidents.

“…However thermal radiation from remote fires is also of great interest. For example, tanks located near forest fires Heymes, Aprin, Ayral, Slangen, & Dusserre, 2013;Rossi, Simeoni, Moretti, & Leroy-Cancellieri, 2011) or burning buildings (Birk, 2000) may suffer failure if the fire intensities are high enough.…”

This paper describes an experimental study of 2300 L pressure vessels exposed to remote fire heating by a natural gas fuelled wall fire simulator. The tanks were filled to 15% capacity with commercial liquid propane. The flame intensity and distance were varied to study the effect of different heating levels on the tank and its lading. The fire simulator is first characterized with tests including fire thermocouples, radiative flux meters and thermal imaging. With the appropriate positioning of a target tank it is possible to get very realistic fire heat fluxes at the tank surface. Three tests were conducted with the 2300 L tanks filled to 15% capacity with propane. The tanks were positioned at three different distances from the wall fire resulting in measured average peak heat flux at the tank surfaces ranging between 24 and 43 kW m À2. The data shows rapid rise in vapour space wall temperatures, significant temperature stratification in the vapour space, and moderate rate of pressure rise. These results provide excellent data for the validation of computer models used to predict the response of pressure vessels exposed to moderate heating from a remote fire.
