Abstract: A breaching device for cutting through a substrate. There are several embodiments of the breaching device. In one embodiment, the device includes a hub assembly with a rotatable ring and a plurality of RM feed assemblies attached to the ring. In another embodiment, the device includes a disc, wherein the disc is rotatable and includes a plurality of slots, a shaft joined to the disc about which the disc rotates and a plurality of RM feed assemblies attached to the disc and arranged in the slots thereof. In another embodiment, the device includes a plurality of carts linked together, wherein each of the carts includes a cart body to which is coupled to an idler wheel, a wheel with an in-wheel motor and a platform and for each cart, a RM feed assembly retained on the platform. The RM feed assemblies include ejecta nozzles that may be positioned at selectable angles.

Abstract: A breaching device for non-explosively cutting through a substrate, such as the leg of an offshore oil platform or other large cylinder from within the leg or large cylinder. The device includes a ring and a plurality of Reactive Material (RM) feed assemblies. Each RM feed assembly is arranged around the ring and includes an extendible nozzle. Each RM feed assembly includes a cavity that may contain RM that when ignited exits the nozzle. The nozzles are spring loaded and arranged to extend toward the inner surface of the substrate to be cut when the ring is rotated and/or oscillated. This arrangement results in a substantially uniform cut of the substrate from within with much less danger, material, equipment and cost than is currently required to remove large water-based structures.

Abstract: A device for either or both of metal cutting and metal welding. The device is configured to a standard service side arm and other guns and/or other types of tools to cut and/or weld metals for the purposes of breaching and welding metals in a range of applications, including in air and underwater, without degrading the primary purposes of the gun or other tools. In one embodiment, the device includes a reactive material cartridge and a nozzle adapted for attachment to a muzzle. In another embodiment, the device includes a muzzle-loading tube including the reactive material and a nozzle configured to shape the reactive material exiting the tube.
