A gaseous oxygen (O2) pipe failed at around 4 am in a liquid oxygen production unit located in a port area. This pipe, most of which was buried underground, crossed the River Rhine to supply a German steelworks. The pressure of 30 bar in the neighbouring pipe was within the operating pressure range at the time of the incident. The establishment's internal emergency plan was activated. Relatively significant damage was subsequently observed: 4.6 t of O2 (as the pipe emptied) were discharged in 13 minutes, stones and gravel were blasted throughout [...]
Feedback on the flooding of industrial sites in January 2018 in the Bourgogne-Franche-Comté region (France)
At around 8:55 p.m., a natural gas explosion (vapour cloud explosion - VCE) occurred on a bridge pier containing a polyethylene natural gas pipeline (DN125) passing through a stainless steel sheath, and a steel pipeline (DN 114). A fire had initially broken out at around 8 p.m. in a squat on another pier. The heat fluxes released caused the steel pipe to bend and the polyethylene pipe to melt. Natural gas was thus able to migrate through the sleeve via its couplings and form explosive pockets.
