Object and purpose of research. This paper discusses protective structure for a pneumatic test rig intended for experiments with the elements of underwater mining system at KSRC Open Test Tank. The purpose of this study was to justify the design parameters ensuring the safety in case of an emergency leakage from the tested equipment. Materials and methods. The study followed the methods of computer-based simulation to analyse gas dynamics of leakage escalation and its effect upon the protective structure. Main results. This paper presents development results of a floating submersible protective structure, with analytical estimates of hazardous factors and protection robustness in case of a hypothetical emergency during pneumatic tests of equipment. Conclusion. Protective structure design suggested in this paper for given conditions of submerging into an open tank and given conditions of pneumatic tests (pressure 69 MPa, nitrogen volume 1 m3) prevents hazardous leakage to the environment. Accordingly, these tests will be safe for both personnel and test facilities.
