FIELD: underwater cutting and rescue operations with salvaging of large-sized objects in oil industry. SUBSTANCE: in process of cutting article is subjected to action of jet of products of combustion of solid fuel which contains Al, Fe and/or Ni powders with total content of metal powders 20-30% and size of particles 50-200 μm. During process products of combustion are accelerated up to supersound velocities. EFFECT: increased speed of cutting and improved quality of cuts.
