The storage takes place in tanks with thermal super-insulations, which are in application for decades, but there is only limited knowledge about its behaviour in a fire scenario. This represents a major incident that may generate extraordinary loads on the tank and its insulation system, and that eventually lead to a sudden tank failure. This paper presents a test rig called the Cryogenic High Temperature Thermal Vacuum Chamber (CHTTVC), which can be used to test typical thermal superinsulation’s under cryogenic and fire-like conditions in parallel. The test method makes it possible to measure the heat flow through the thermal superinsulation over time and to investigate the degradation behaviour of the insulation within a test. In the paper results from the first tests are presented.

Does this also entail new risks for instance from a BLEVE? A key to answer this question is to research representative fires by its characterization and its effect on the insulation. At BAM’s technical test side in Germany, a test series was started to answer this question among others. This paper presents results on a pool fire under a colorimeter, that simulates a tank. The investigation points out, that the full fire characterization approach allows to represent the fire. The findings are relevant for the investigation of a representative design fire that is applicable for the approval and improvement of tanks as well as to research accident scenarios and their consequences.
