Abstract
A modular system for protecting a critical asset includes a plurality of vertical members extending vertically upwardly from a ground surface, and inner and outer stacks of spaced-apart horizontal members connected between adjacent pairs of the vertical members defining a vertical wall. The spaced-apart horizontal members have cross sections and spacings such that no line can be drawn through the wall without intersecting with one or both of the inner and outer stacks. The cross sections of the horizontal members in both stacks include elongated angled surfaces such that projectile on a trajectory toward the critical asset is deflected upwardly or downwardly and away from the critical asset. In a preferred embodiment, the horizontal members are angle irons. In a more preferred embodiment the horizontal members are 1/2″ 90-degree steel angle irons oriented sideways, such that the elongated plates making up the angle irons are 45 degrees off horizontal.
Description
- This invention relates generally to critical asset protection and, in particular, to a modular ballistic deflection barrier assembly.
- Terrorist targets include any facility which, if damaged of compromised, would wreak chaos in some form. In addition to large buildings, bridges and dams, the list includes electrical transmission stations, transmission substations and their associated primary control centers. If rendered inoperable or damaged as a result of a physical attack, such an assault could result in widespread instability, uncontrolled separation, or cascading within an interconnection.” As such, the North American Electric Reliability Corporation (NERC) has instituted CIP-014-1, a program to identify and provide physical security for the physical protection of the bulk power systems. The proposed standard requires transmission owners to perform a risk assessment that identifies their critical transmission stations and substations, and their associated primary control centers. Once the critical facilities are identified, the proposed standard requires the owners to evaluate the physical threats and to develop and implement a security plan for these critical facilities.
- The idea behind the requisite security system is to “deter, detect and delay.” There are many options for external detection including visible-light and thermal cameras, vibration detection, and radar. Proposed measures to deter include the construction of hardened perimeters around entire sites to erecting walls around specific equipment. Some mitigation strategies involve constructing partial screens to mask the location of critical equipment. Protection against larger ballistic projectiles presents particular challenges. Large solid structures are inflexible, expensive and likely not conducive to aesthetic decoration. Lighter weight structures, on the other hand, may not be effective.
- Ballistic resistant wall panel enclosures have been designed to prevent damage from projectiles. Such enclosures utilize fiberglass reinforced panels in conjunction with perimeter fencing. The Ballisti-Wall and Ballisti-Cover from Sensei Solutions LLC of Holly Ridge, NC are lightweight, corrosion proof, non-conductive, and electromagnetically transparent products that can be customized and implemented to protect critical substation assets. Constructed from multiple layers of woven fiberglass encapsulated with a proprietary resin system that produces a rigid panel with exceptional ballistic resistance, the unique composite matrix of the panels allow for the retention of the projectile to avoid potentially hazardous ricochet.
- The Intelli-Firewall manufactured by Composite Support & Solutions Inc. of San Pedro, Calif. has been installed by large utilities to protect transformers in major substations in California. The product features a ceramic composite material that is manufactured using a ‘green’ process technology. The modular design uses light weight [320 lb] panels that facilitate handling and installation. The system is designed to minimize load bearing impact at the base of the wall using steel columns, casings and other components that allow for rapid removal and reassembly to optimize flexibility.
- This invention resides in a modular system for protecting a critical asset on a ground surface. The system comprises a plurality of vertical members extending vertically upwardly from a ground surface, and inner and outer stacks of spaced-apart horizontal members connected between adjacent pairs of the vertical members defining a vertical wall.
- The spaced-apart horizontal members have cross sections and spacings such that no line can be drawn through the wall without intersecting with one or both of the inner and outer stacks. The cross sections of the horizontal members in both stacks include elongated angled surfaces such that projectile on a trajectory toward the critical asset is deflected upwardly or downwardly and away from the critical asset.
- In a preferred embodiment, the horizontal members are angle irons. In a more preferred embodiment the horizontal members are ½″ 90-degree steel angle irons oriented sideways, such that the elongated plates making up the angle irons are 45 degrees off horizontal.

FIG. 1 is a simplified schematic diagram illustrating a modular ballisticdeflection barrier assembly 100 configured in accordance with the invention. The system broadly comprises a plurality of uprightvertical members 104 an generallyvertical walls 102 supported between adjacent pairs of themembers 104. The critical asset, which may be an electrical transmission station, transmission substation, control center, building or any other form of infrastructural unit, is shown entirely surrounded by theinventive barrier 100; however, being modular in nature, thebarrier 100 may be configured to partially surround an asset or any other appropriate arrangement. - In the preferred embodiment, as described in detail herein, the vertical upright members are steel I-beams and the
walls 102 are constructed from inner and outer stacks of spaced-apart horizontal members. Thus, the walls are not “solid” as inferred byFIG. 1 , but instead resemble “louvers” which allow air to pass therethrough while deflecting and blocking ballistic penetration. As schematically illustrated inFIG. 1 , the corner and support posts are preferably buried several feet at 106 below aground surface 108. In the preferred embodiment the vertical members are on the order of 10 feet apart, though the invention is not limited in this respect. The walls may be of any height depending upon the asset to be protected. -
FIG. 2 is a top view showing the I-beamvertical members 202. 204, 206 andfield plates FIG. 3 shows the way in which V-shapedhorizontal members beams 200 through the field plates. As can be seen, the preferred assembly includes inner and outer stacks of spaced-apart horizontal members connected between adjacent pairs of the vertical members to define each vertical wall. The drawing on the left shows how the horizontal members attach to an inner surface 220 of a vertical I-beam, and the drawing on the right shows how the horizontal members attach to anouter surface 222 of the vertical I-beam. The spaced-apart horizontal members have cross sections and spacings such that no line can be drawn through the wall without intersecting with one or both of the inner and outer stacks. - The cross sections of the horizontal members in both stacks include elongated angled surfaces such that projectile on a trajectory toward the critical asset is deflected upwardly or downwardly and away from the critical asset. In the preferred embodiment, the horizontal members are ½″ steel angle irons, though other stock with different thicknesses may alternatively be used. Such angle irons comprise two strips of metal intersecting at an angle defining a V-shaped cross section and an elongated common edge. In the preferred embodiment, the common edges of the horizontal members in both of the stacks are oriented outwardly away from the wall. In the preferred embodiment, 90-degree angle irons are used sideways, such that the angles of the plates making up the I-beams are substantially 45 degrees from horizontal.
