Abstract
The article presents the structure of the mathematical layer for digital twins (DT) of hazardous production facilities (HPF) operated by gas transportation enterprises. Mathematical models of technical device destructions, models to control parameters of technological processes are presented, the types of affecting factors which can influence the personnel of HPF are described, as well as a safety assessment model for the evacuation of personnel in the event of an accident or a fire. The presented structure of DT and models make it possible to adequately describe the features of HPF and optimise operational safety. The areas of application of digital twins in the production activities of a gas pipeline enterprise have been determined. To determine the most possible scenarios of accidents at HPF the presented models have been tested and implemented in the operational activities of JSC “Gazprom transgaz Tchaikovsky”.
