Abstract

Purpose. Ensuring the safety and the efficiency of special rescue and recovery operations at depressurization of pipelines and tanks the transport and storage of aggressive media in the liquid state, including fire - and explosive materials in the liquid state. This largely depends on the special forces carried out operations with the use of certain technical tools. Method. Application of the methods of modeling and statistical processing at a stress occurs in the shells, associated with the sealing process equipment. Results. Upon liquidation of depressurization in the process equipment pipeline transportation and liquids storage tanks under pressure, the head of special units required to make operational decisions for the emergency and recovery operations (ATS) and the repair and construction works (PCP) based on efficacy and safety of their conduct. Moreover, the decisions must be assessed from the point of view of expediency of engagement units in certain conditions, seeking out the many rational decisions to choose the best (optimal). Refined generalized scheme applying tension cables means using MK1 mini-complex. In the transition from a system of mutually parallel to the converging forces of the process of converting the system power factor in the rope system similar to this, which occurs in a belt drive. The term "pseudo gear ratio", keeping us proved useful in creating tactical and technical support for the tasks of emergency sealing of cylindrical surfaces with MK1. Scientific novelty. On the basis of theoretical studies to identify areas of rational
allocation MK1 mini-complex at the elimination of accidents related to the depressurization of various types of tanks and pipelines for transport and storage of liquids, considering the efficiency and safe operation. Practical meaningfulness. On the basis of experimental and theoretical studies developed tactical and technical support to the use of mini-complex MK-1 and its components in terms of certainty.
