Barrier1 Systems has extensive experience providing unique missile barriers that protect critical equipment, buildings, access openings, infrastructure, and other facilities from projectiles. Our Missile Protection Barriers are robust solutions that can be designed to stop tornado projectiles, hurricane projectiles, steel pipes, wooden beams, airborne automobiles, and small planes. Our barriers have been provided at Nuclear Facilities, Power Plants, and other locations.
Barrier1’s lightweight designs for access doors have many advantages:
One (1) person can manually open and close large missile rated doors
No actuators, electronics, backup power, or other points of failures
Eliminates heavy reinforced concrete and steel doors
Minimizes long-term plant maintenance and testing burdens
Modular prefabricated designs are bolted together in the field.
Barrier1 Systems offers turnkey capabilities and provides engineering & calculations, specialized missile impact testing, laboratory & materials testing, fabrication & assembly, and installation support. For Nuclear Power Facilities, our Missile Protection Barriers have been provided under both Augmented Quality and Safety Related Standards. Each location's projectile arresting requirements are evaluated upfront, followed by engineering, design drawings, and calculations.
Physical testing of the missiles can also be performed. Fabrication and Assembly is completed upon design approval. Barrier1 Systems will provide a solution that meets your projectile arresting requirements, operational requirements, and other site specific needs.
Robust Projectile Protection Barriers, Doors, and Enclosures
Barrier1 Systems has provided missile protection barriers and associated work throughout the US, in Canada, and Japan. Customers include Exelon, Entergy, First Energy, FPL, NextEra Energy, Ameren, XCEL, PG&E, Los Alamos, Westinghouse, Ontario Power, Canadian National Laboratories, Hokkaido, various General Contractors, and others.
When providing solutions, Barier1 Systems has worked with engineering firms including Enercon, Sargent & Lundy, Burns & McDonnell, CBI, Jensen Hughes, LPT, and others during the design, testing, and review processes. Last, Barrier1 Systems interfaces with the General Contractor installing the Missile Protection Barriers, where Barrier1 provides installation support, construction sequencing recommendations, bill of materials, installation details, onsite reviews, and other assistance to efficiently complete the installation work scope.
For each Location, missiles or projectiles are first evaluated. This includes missile dimensions, material types, weights, impact velocities, impact angles and other characteristics. Wind loading, seismic loading, pressure drop, building depressurization rates, and projectile impact heights are also reviewed. Location specific constraints are also considered.
Design drawings and calculation packages are provided that meet regulatory requirements. Global and local affects of missile impacts on the barrier are analyzed. The ability of the barrier to stop the missile impacts is demonstrated. Physical missile impact test data supplements calculations and conclusions. Laboratory test data showing properties of key components is provided. LS-Dyna modeling or other finite analyses can be provided. Drawings and calculations are sealed by a Registered Professional Engineer (PE).
Our unique barriers are comprised of multiple layers of protection that "give" and absorb energy upon impact. Barrier1 Systems has designed protection barriers to arrest a multitude of different projectiles including massive airborne automobile missiles, small planes, utility poles, steel pipes, 1" diameter steel spheres, planks, steel beams, and other projectiles. Additionally, our designs consider a multitude of different impact velocities.
Barrier1 Systems has collected significant data from past physical projectile testing. Past testing has included massive airborne automobiles, small diameter steel rods, spheres, midsize, and large projectiles. The projectiles tested have been comprised of different material types, dimensions, cross sections, weights, and impact velocities. Past testing has included 15,000 lbs. vehicles, 4,000 lbs. airborne automobiles, 335 lbs. steel tubes, 27 lbs steel rods, steel spheres, and others.
Barrier1 Systems has the equipment, facilities, experience and capabilities to launch projectiles of varying sizes and weights into the barrier, while achieving a specified impact velocity which is verified by high speed cameras and radars. Different materials, such as Ballistic Rated Steel, can be tested within the barrier to evaluate improvements in perforation resistance and other properties. Third-party independent engineering firms document the projectile testing, results, and prepare reports. Test data supplements the calculations and conclusions, and verifies the barrier's ability to arrest the projectiles.
Laboratory testing has been completed to verify properties of components and connections used in the Missile Protection Barriers. This includes tensile strength, shear strength, elongation, resistance to perforation, and other properties. Site specific materials testing can be completed upon request. In addition, raw steel materials can be tested prior to fabrication, to verify properties provided in mill test certificates. Materials test data is used in calculations, with backup documentation and references provided. Materials testing is completed by a third-party independent laboratory, under approved QA/QC procedures. Calibrated equipment is used.
Fabrication & Assembly
Barrier1 Systems provides in-house fabrication & assembly of its Missile Protection Barriers. Steel materials are procured from approved vendors with Mill Test Certifications provided. Barrier1 has the equipment and manpower to complete fabrication and metals works. Certified welders, technicians, QA/QC persons, and Engineers are employed. Independent third-party Certified Welding Inspector (CWI) review and certify welds prior to shipping. Final coatings are applied which may include epoxy paint, galvanizing, powder coating, zinc enriched coating, and custom coatings. Barrier1 provides packaging and shipping.
Missile Protection Barriers can be completed under varying levels of QA/QC depending upon the site's requirement. This may include detailed weld traveler drawings, onsite dedicated CWIs to sign off on step-by-step welding, periodic engineering reviews, fit-up inspections, QA sign-offs, onsite materials testing, dedicated onsite storage of raw materials, and other QA/QC. Barrier1 can complete Safety Related Fabrication & Assembly required by Nuclear Plants.
Expediting the schedule is within our control. By providing turnkey engineering, design and fabrication in-house, Barrier1 has better control over the schedule and can expedite work. Changes needed to design documents, drawings, calculations, components, materials and fabrication are more efficiently coordinated since in-house.
Barrier1 Systems designs & fabricates modular components that comprise the Missile Protection Barrier. Our design goals are to have 4 to 5 modular prefabricated components that bolt together in the field, with minimal to no field welding.
Components are shipped with pre-welded lifting lugs. Barrier1 Systems provides installation instructions and photographs. The design drawings call out specifications, dimensions, reinforced concrete design, materials, tolerances, hardware, anchors, weights and other information. Prior to installation, Barrier1 Systems discusses design drawings, installation sequence, constraints and requirements with the General Contractor to help facilitate installation.
While installation is ongoing, Barrier1 Systems is available to answer questions and provide continued support. If requested, onsite oversight can be provided during installation.
