The downhole tool industry commonly conducts tests that require pressurization of a vessel. The most common failure mode is through the launching of end caps, plugs, and fittings as opposed to a catastrophic rupture of the vessel body. This type of vessel failure during high-pressure gas testing can produce significant threats to nearby personnel in the form of high-energy projectiles and blast waves that must be blocked or dissipated before reaching personnel. Adequately designing a structure to contain this energy depends on how well a worst case scenario event can be modeled.

Blast waves ensue from a pneumatic pressure test failure. As a vessel fails, the volume of pressurized gas will expand into the surroundings. A computational fluid dynamics (CFD) model of the pressure vessel and its enclosure will provide an accurate assessment of the blast loads in the environment.
