Abstract
The invention relates to a device for securing a leak of fluid from equipment containing a pressurised fluid. The device comprising a gas-tight containment device disposed around the equipment and defining a volume, Vconf, between the inner surface of the sealed containment device and the outer surface of the equipment. A vent is formed by one or more ports in the sealed containment device, each port being defined by its cross-section and shape. According to the invention, the volume, Vconf, the cross-section and the shape of each port are configured such that, in the event of a leak of flow rate Qf, the fluid is discharged through each port in the form of a turbulent jet.

A device for securing a leak of a fluid that may occur in pressure equipment containing that fluid, in which the securing device is configured to secure a leak having a given leakage flow rate of said fluid Qf said securing device comprising:
- a fluidtight containment device, arranged around the pressure equipment and defining a volume Vconf between the internal surface of said fluidtight containment device and the external surface of the pressure equipment;
- a vent made up of one or more orifice(s) in the fluidtight containment device, each orifice being defined by its cross section and by its shape;
- and in which the volume Vconf, and the cross section and the shape of each orifice are configured so that in the event of a leak with a flow rate Qf, the fluid is discharged through each orifice in the form of a turbulent jet.
