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.
