Safe storage of fuel is the sole reason for the existence of Convault protected aboveground fuel tanks (AST). Its design, testing, and quality of production have gained it an excellent reputation during the last 20+ years. To date over 32,000 ConVault AST's Remain in service without a single reported system failure despite being subject to various catastrophes including hurricane's, floods, vehicle impact, ballistics damage, fire damage, tornadoes and more.

ConVault Blast Effects Analysis

ConVault is currently the only AST on the market to have performed a Blast Effects Analysis. Karagozian & Case (K&C), a World Leader in Blast Consulting and Blast-Resistant Design, recently completed a Blast Effects Analysis (BEA) on the design of the ConVault protected Aboveground Storage Tank. Three different threat scenarios were investigated to determine the inherent blast resistance of ConVault's design for the tank. Scenarios were chosen to reflect blast distances recommended in FEMA’s Reference Manual to Mitigate Potential Terrorist Attacks Against Buildings.

Scenarios Investigated Included:

• Suitcase Bomb (50 lbs. of Explosives at 5ft.)
• Car Bomb (500 lbs. of Explosives at 20 ft.)
• Vapor Cloud Explosion (10 psig...the higher end of expected pressures)

A 2000 gallon tank was used to represent a typical ConVault tank design. The criteria for a successful test was considered to be one where the tank would not move more than two inches, and the integrity of the primary tank would not be compromised. In a real life situation there should be no fuel leaks from the primary tank.

BEA Conclusion

The tank passed all three tests. It withstood the blast with high limit pressures resulting from the explosions from a vapor cloud, a 50 lb HE – TNT blast centered at 5 feet from the tank and a 500 lb HE – TNT blast centered at 20 feet from the tank. The magnitude of these blasts at the respective proximities would be expected to destroy and/or relocate lighter, less robust fuel storage tanks. However, the BEA showed the ConVault AST will not only remain in place, it will survive with no fuel leakage from the primary tank. The mass provided by the concrete outer shell protected the steel tank extremely well, and greatly enhanced the resistance to all blasts. Additional information is available upon request.
