DEFINITIONS

[0018] An improvised explosive device (IED) is a bomb constructed and deployed in ways other than in conventional military action. It may be constructed of conventional military explosives, such as an artillery round, attached to a detonating mechanism IEDs are commonly used as roadside bombs.

[0019] Munitions and Ordnance Remediation Blanket (MORB) is the device taught by the present invention for the safe and environmentally friendly breaching and neutralization of the energetics fillers in UXOs on land and especially munitions found at underwater sites.

[0020] Unexploded ordnance (UXO) are explosive weapons (bombs, bullets, shells, grenades, land mines, naval mines, bulk explosive and energetics, etc.) that did not explode when they were employed and still pose a risk of detonation, potentially many decades after they were used or discarded.

DETAILED DESCRIPTION OF THE INVENTION

[0021] In the following detailed description of the invention of exemplary embodiments of the invention, reference is made to the accompanying drawings (where like numbers represent like elements), which form a part hereof, and in which is shown by way of illustration specific exemplary embodiments in which the invention may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention, but other embodiments may be utilized and logical, mechanical, electrical, and other changes may be made without departing from the scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined only by the appended claims.

[0022] In the following description, numerous specific details are set forth to provide a thorough understanding of the invention. However, it is understood that the invention may be practiced without these specific details. In other instances, well-known structures and techniques known to one of ordinary skill in the art have not been shown in detail in order not to obscure the invention. Referring to the figures, it is possible to see the various major elements constituting the apparatus of the present invention.

[0023] Now referring to the Figures, the device is a Munitions and Ordnance Remediation Blanket (MORB) as taught and used by the present invention are shown. The present invention discloses the design for safe and environmentally friendly breaching and neutralization of the energetics fillers in UXOs on land and especially munitions found at underwater sites (underwater UXOs). The design mirrors a blanket consisting of multiple layers, each with a separate function.

[0024] Now referring to FIG. 1, the components of a Munitions and Ordnance Remediation Blanket (MORB) 100 includes: an impermeable outer membrane layer 101 made of plastic or similar fiber; a commercial blasting mat layer 102; a neutralization reagent layer 103, in one embodiment MUNIREM, in powder or solution forms is used—acting as an instant explosives neutralization reagent; one or more other abiotic munitions neutralization reagents, e.g., black carbon plus sulfide, metal reductants (zero valent iron). Etc.; and a commercial water-soluble seal or cover 104 (e.g., PVA water-soluble bags for both powders and solids and similar water-soluble packaging).

[0025] In one embodiment, MAZZELLA patented wire rope blasting mats are used as the blasting mat layer 102. In an alternative embodiment, the blasting mat is a polymer membrane is the blasting mat layer 102.

[0026] The MORB taught by the present invention builds on explosion hazard mitigation (safety) provided by the blasting mat and slow release of the reagent provided by the encapsulation of the MUNIREM reagents in slow release tablets or the MUNIREM coated with a slow decay polymer.

[0027] MUNIREM is a mature and award winning technology utilizing reduction chemistry to: instantly neutralize and degrade explosives and chemical warfare materials (CWM), while also stabilizing metals as the insoluble metal sulfides. MUNIREM is a solution for a broad range of explosives and munitions constituents including Mustard (CWM), HMX, RDX, TNT, TNR, DNTs, ADNTs, NBs, NDMA, Black Powder, Lead Styphnate, Nitrocellulose, Nitroguanidine, PETN, PBX and reactive Aluminum. The very short cleanup time and closeout associated with this technology eliminates the O&M costs (30-50% savings) associated with other remediation technologies.

[0028] MUNIREM applications have supported demilitarization and remediation projects at United States Department of Defense installations, Canada, Australia, Taiwan and private industry sites.

[0029] MUNIREM formulations and applications are tailored to each site to ensure optimum performance and desired results. It can be applied as a solid or aqueous solution to achieve optimal and desirable results.

[0030] Contaminated soils treatment involves mixing MUNIREM powder into the soils and adding water to achieve in-situ or ex-situ remediation.

[0031] Groundwater remediation involves injection of the MUNIREM solution into the site groundwater to instantly degrade the dissolved contaminants and create permeable reactive aquifer solids for long-term treatment of the plume.

[0032] Decontamination applications involve spraying the MUNIREM solution on building walls, large equipment and scrap metals (including bombs shells, bomb components, projectiles); and soaking small sized equipment in MUNIREM baths.

[0033] Alternative to Open Burn/Open Detonation involves application of MUNIREM in solution or powder form to neutralize bulk explosives and destroy residual explosives in different materials.

[0034] The different formulations for MUNIREM are: MuniRem-R811E, MuniRem-R541E, MuniRem-FE, and MuniRem-Gel.

[0035] MUNIREM has been demonstrated and validated at US Department of Defense installations to: Neutralize recovered bomb contents and decontaminate bomb casings; Rapidly treat high concentrations of TNT, RDX and HMX in soils; Degrade explosives in water including pink water to non-detect concentrations; Degrade explosives in spent activated carbon (GAC) from pink water treatment; Neutralize highly reactive open burn open detonation (OBOD) ash; Treat bag house waste which passed TCLP test; Destroy high explosives and stabilize metals in demilitarization sludge; Neutralize solid propellants of different particle sizes; Degrade sulfur mustard to ethylene gas (the same gas from degradation of chlorinated solvents by zero valent iron and anaerobic bacteria); Decontaminate walls in explosives handling and processing buildings using a spray of liquid MUNIREM reagent; and Decontaminate demilitarization/militarization equipment.

[0036] As shown in FIGS. 2-3, the Munitions and Ordnance Remediation Blanket 301 (MORB) of the present invention can be used in-situ and on-site remediation of UXOs, decaying munitions 202, and energetic point sources at underwater munition and terrestrial sites 201 as an alternative to open detonation/open burning. It is a green alternative for explosives destruction providing the safe neutralization of energetics and counters IED technology.

[0037] Referring to FIG. 4, in a first method directed to Underwater UXO 401, the blanket device is exposed to the unexploded ordnance using one of multiple breaching mechanisms, for example abrasive water jet cutting or similar 402. In a next step, mitigators cover the breached/decaying/leaching point source emitter with the MORB 403. The MORB is anchored to seafloor or uses a sturdy fixture, which allows water to permeate the water-soluble cover material to dissolve membrane and create contact between the energetics, MUNIREM and Water 404. The MORB is then left in place for the reaction to proceed to completion and then finally, allow the recovery of any remaining metal casings to be recycled 405.

[0038] In a second method of application of the MORB in an underwater UXO application 501, first a low order charge is attached to the located underwater UXO 502. Next, the UXO is enclosed in a MORB 503. The MORB is anchored to the seafloor or similar 504. The charge is set off to crack open or breach the ordnance 505. For decaying/leaking point source ordnance simply enclose in MORB 506. If on land, add water to saturate and initiate explosives neutralization reaction by a neutralization reagent such as MUNIREM or similar 507. Next, leave in place for the reaction to proceed and then finally, recover y of any remaining metal casings to be recycled 508.

[0039] Other forms of breaching the ordnance, such as drilling, waterjet cutting, and cryogenic fracturing may be used in the method. Affixing and detonating a charge is used in an exemplary manner and any of the other forms may be substituted based on feasibility and best practices in the industry.

[0040] Now referring to FIG. 6, in an application for an UXO on Land 601, first affix a low order charge to the located UXO on land 602. Next, enclose the UXO in MORB 603. The MORB enclosed UXO may be submerged in a large tank of water or lagoon 603. Anchor MORB to ground or similar 604. Set off the charge to crack open or breach the ordnance 605. Add water to saturate and initiate explosives neutralization reaction by a neutralization reagent such as MUNIREM or similar 606. Leave in place for reaction to proceed to completion and finally, recover metal casing and recycle 607.

[0041] Thus, it is appreciated that the optimum dimensional relationships for the parts of the invention, to include variation in size, materials, shape, form, function, and manner of operation, assembly and use, are deemed readily apparent and obvious to one of ordinary skill in the art, and all equivalent relationships to those illustrated in the drawings and described in the above description are intended to be encompassed by the present invention.

[0042] Furthermore, other areas of art may benefit from this method and adjustments to the design are anticipated. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents, rather than by the examples given.
