Blast/Impact Resistant

Blast/Impact Resistant
post_thumbnail

In today’s increasingly unstable political and social environment, safety and security has become a top concern with facility owners storing petroleum and other flammable liquids.

With this heightened awareness of security in mind, ConVault Inc. recently retained Karagozian & Case (K&C), a World Leader in Blast Consulting and Blast-Resistant Design, to complete a Blast Effects Analysis (BEA) on the design of the ConVault protected Aboveground Storage Tank (AST). ConVault AST’s feature six inches of reinforced concrete surrounding both the primary and secondary containment of the fuel tank.

Three different threat scenarios were investigated to determine the inherent blast resistance of the ConVault design. These scenarios were chosen to reflect blast distances recommended in FEMA’s Reference Manual to Mitigate Potential Terrorist Attacks Against Buildings.

The scenarios investigated were:

  • A blast from a vapor cloud such as might accumulate at a refinery with explosive pressures at 10 psig (the higher end of the range of expected pressures);
  • A blast from 50 lbs of High Explosive (HE) TNT as might be carried by a typical suicide bomber (Man Portable Improvised Explosive Device); and
  • A blast from 500 lbs of High Explosive (HE) TNT representing a typical car bomb (Vehicle Borne Improvised Explosive Device).

A 2000 gallon tank was used to represent a typical ConVault tank design. The ConVault successfully met both criteria required to succesfully pass the blast test.

The two criteria for a successful test are:

  • The tank would not move more than two inches, and
  • The integrity of the primary tank would not be compromised ( no resulting fuel leaks from the primary tank).

Overall, the Blast Effects Analysis indicates that the ConVault AST is very resistant to the effects of the blast loads considered. The mass provided by the reinforced concrete outer shell protected the steel tank extremely well, and greatly enhanced the resistance to all blasts. It withstood the vapor cloud blast, a 50 lb TNT blast centered at 5 feet from the tank, and a 500 lb 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 ConVault AST will not only remain in place, it will survive with no fuel leakage from the primary tank.

The strength and durability of the primary steel tank enclosed in steel reinforced concrete allows ConVault to provide unsurpassed protection against blast and impact damage. ConVault excels where other tanks fail when it comes to protecting the fuel containment steel tank from puncture due to impact or explosive blast. The exterior steel reinforced concrete is engineered to prevent puncture and withstand the impact from transportation related to facility operations such as forklifts and motor vehicles.

UNMATCHED PROTECTION OF THE PRIMARY TANK AND SECONDARY CONTAINMENT

Convault encases BOTH THE PRIMARY TANK AND THE SECONDARY CONTAINMENT in 6” of steel-reinforced concrete that outperforms stringent UL 2085 requirements for blast, fire, and ballistic impact protection. From coast to coast across the USA and around the world you will find countless examples of Convault tanks reliably performing through extreme weather and catastrophic events. That’s one reason why Convault is the preferred tank at military, paramilitary, and public safety installations. A recent study by Karagozian and Associates demonstrated how the inertia and mass of Convault’s steel reinforced, monolithic concrete entombment protects the tank from blast and impact.

Karagozian & Associates Blast Effects Study: Concrete

  2. The tanks should be located a minimum of 1/3 the height of the vault (40 feet maximum) away from down slopes - greater than 3:1, and 1/2 the height of the vault (15 feet maximum) away from up slopes smaller than 3:1.
  3. Tanks located in areas subject to flooding must be protected against floatation. Flood resistant tie-down brackets are available for all tank sizes to resist floatation during complete submergence.
  4. Aboveground tanks should not be located over underground utilities or directly beneath overhead power and telephone lines.
  5. The tank should be protected from vandalism and accidental damage in accordance with all the applicable codes.
  6. Fire department vehicle access should be provided within 150 feet of any tank.
  7. The venting of a tank to a remote location must include the use of a steel pipe equal to or greater in size than the vent outlet, and the methods of supporting such piping against displacement must comply with local codes. Provide the vent piping with a slope to ensure that all condensed vapors drain back to the tank.
  8. Collision protection is recommended on the sides of the tank exposed to traffic. This is generally accomplished with pipe bollards. Always check state and local codes for specific requirements. See Figure No. 5 for sample installation.
    • NOTE: The location of each ConVault® tank is stored in the central data bank. If the tank is to be relocated to a different location, ConVault® Inc. must be properly notified to update the data bank. The product limited warranty could be voided if ConVault® is not informed of tank relocation or if tank is not reinstalled in accordance with these installation instructions. It should be noted that ConVault® Warranty is conditional on installation of tanks in accordance with ConVault® Installation Instructions. Your attention is specifically drawn to the tank site selection and foundations requirements.

Foundations

  1. Tank location and foundation must comply with the current edition of Uniform Building Code requirements and all the applicable local codes and ordinances.
  2. An alternative to pouring the slab in the field is to purchase a precast slab from the manufacturer.
  3. The foundation for the tank must be designed to support the tank plus the weight of the maximum amount of product the tank will be storing. The foundation design must also include provision for draining surface water away from the tank to minimize the risk of fuel accumulation under the tank from the overfill or spills.
  4. Tanks located in areas subject to earthquake must be protected against seismic forces. Optional earthquake restraints are available. The restraints can be retrofitted to the slab should local requirements change. The restraints are mounted on the slab and are secured with anchor bolts directly into the slab. The tank feet rest in the restraints and do not require bolting directly to the tank.
  5. The tank located in areas subject to hurricane must be provided with hurricane hold down restraints.
  6. The tank foundation is to sit on undisturbed earth or compacted fill, free of organic material.
  7. The following minimum soil characteristics may be used if the ConVault tank is installed on a continuous solid slab which will uniformly distribute the weight of the tank and its contents to the soil:
    • Bearing Capacity: minimum 1,000 but preferably 2,000 lb. per sq. ft.
    • Total settlement: 1 inch maximum.
    • Differential settlement: 1/2 inch maximum.
    • Provide a minimum six inch (6") thick granular sub-grade, compacted and graded to a level uniform subsurface prior to the cast slab placement or pouring of the cast-in-place slab.
    • A geological engineer should evaluate the effect of the water table and frost lines if such unusual conditions exist at the site.
    • Soil surface under foundation should be flat within 1/16" per foot. Soil around foundation should be sloped away 1/8" per foot minimum for 5 feet.
    • NOTE: If Bearing pads are used under the tank legs instead of grouting, the tank foundation and slab should be designed to withstand concentrated loads under the bearing pads.
    • NOTE: The above soil characteristics, foundation and slab design requirements may be revised by a qualified design engineer who would design the foundations and the slab on a site-specific basis.
    • NOTE: Some Authorities Having Jurisdiction require uplift restraints for areas subject to flooding and hurricanes.

Tank Handling

  1. DO NOT HANDLE OR INSTALL TANK WITHOUT HAVING KNOWLEDGE AND EXPERIENCE IN PROCEDURES INVOLVED WITH PROPER AND SAFE INSTALLATION OF AN ABOVEGROUND TANK USED FOR STORAGE OF STABLE, FLAMMABLE AND COMBUSTIBLE LIQUIDS. RELIANCE ON SKILLED AND PROFESSIONAL INSTALLERS IS AN IMPORTANT FACTOR IN AVOIDING DAMAGE TO TANK AND SYSTEM FAILURE.
  2. Equipment required in the shipping and offloading of ConVault® aboveground storage tanks include lifting straps, nylon tie-down straps, crane, forklift, and carpet remnants strategically placed on the bevels to prevent the tie-down straps from scraping the paint loose while the tank is en-route.
  3. Do not handle or move the ConVault unless it is empty. Under no circumstances should a tank containing petroleum product be moved.
    1. Do not drop or drag the tank.
  4. If petroleum product has been introduced in the tank, the tank must be emptied first, then may be relocated using the Department of Transportation Guidelines for transport of fuel containers. Normally, to relocate a tank previously containing flammable liquids, the Authorities Having Jurisdiction require the tank to be cleaned and then moved according to the following guidelines:
    • Remove the liquids from the tank.
    • Rinse the tank three times with an approved cleaning agent.
    • Allow sufficient time for vapors to escape from inside of the tank.
    • Move the tank under the supervision of the Authorities Having Jurisdiction.

Unloading and Setting

  1. The unloading equipment and procedures are critical to setting the tank safely and without harming the people or damaging the tank.
  2. NOTE: The most important aspect of a job procedure is SAFETY. Please ensure that every step of this procedure is carried out with safety in mind, first.
  3. Tanks Weight and Dimensions.
    Please refer to Figures No. 2, 3 and 4 in Product Description. For actual tank weights and dimensions, please contact your ConVault distributor.
  4. Equipment Required & Procedures
    1. A crane or a forklift of sufficient capacity to safely lift and place the unit.
    2. Slings minimum 20 feet long each and rated for the tank weight. The angles between the slings should be at least 50 degrees.
    3. 4-way spreader.
    4. Miscellaneous shackles, tag lines, and rigging tools.
    5. Plan the required crane and rigging capacity to safely unload the tank.
    6. Inspect the tank on the delivery truck prior to unloading. Report any damage in transit to the truck driver and note on the shipping ticket. If the tank is paint coated, it normally comes with two-1/2 pint, two-part touch up kits of paint. Please note that the touchup kit must be mixed prior to application.
    7. Allow sufficient crane time for installing the load block and organizing the rigging.
    8. During unloading and setting, allow one person in-charge to signal the crane operator. Keep people clear of the load and avoid being trapped between the load and building walls and equipment.
    9. Make sure there is no overhead wiring to interfere with crane or boom operation. Provide sufficient room for cranes and boom trucks to off load.
    10. Department of Transportation prohibits transportation of tanks with product and warning labels. Product and warning labels should be installed on site. If installed at the plant, they should be masked prior to shipment. Labels and decals must be placed on the tank in accordance with NFPA 709. Figure No. 6 shows location of labels.

Grouting of Legs

  1. All tanks of 4,000 gallon and larger must be grouted with (non-shrink grout) or supported with alternative engineered pad interface.
  2. We recommend to grout the legs of all tanks, which will provide a uniform load distribution on legs and foundations.
  3. Neoprene pads may be used instead of grouting in accordance with the manufactures recommendations. Also see Note under FOUNDATIONS.

Electrical

  1. Electrical service and fuel piping to the pumps unit should be installed in accordance with the requirements of NEC and NFPA and local code requirements.
  2. All electrical devices used with or located within twenty (20) feet of the ConVault® tank should conform to NFPA 70 Hazardous Locations. All electric conduits and wiring connected to the tank should be explosion proof and in strict accordance with NEC Class-1, Division 1 or other local standards whichever is stricter.
  3. An emergency shutoff switch is required to be mounted in a location visible from the dispenser. The switch is normally mounted on a building wall or a post. The per code switch must be marked as an emergency shutoff switch.
  4. Electrical grounding is required for flammable liquid fuel tanks. ConVault® tanks are provided with two grounding lugs welded to the nipples on tank top.
  5. Pumps and all other equipment used in the hazardous area should be rated by UL or Factory Mutual, FM.
