Abstract:

Security of natural gas sector of developed industrial countries depends on continuous and coordinated work and the key infrastructure. The risk analyses procedure is reviewed. In addition the main factors for determining the pressure regimes of the natural gas distribution grids are also reviewed. In accordance with the natural numbers, numerical values of the factors according to Fourier series are adopted for Tbilisi gas distribution grid for the average 24 hour gas supply.

Keywords: : natural gas distribution network; service quality; risk analysis; dynamic processes.
