The new sources of raw materials are found considerably far away from gas consuming areas as well as from the existing gas transmission mains and raising the effectiveness of longdistance gas transmission becomes, consequently, the task of urgent importance. Analyses of technical-and-economic indices demonstrate that capital outlays on gas transmission will be reduced by 5-10% if pressure in new trunk gas pipelines to be built up to 14 MPa. It is important that the application of higher working pressure and aboveground pipeline laying in Yamal will enable to minimize detrimental man-caused effect on the environment. A whole series of tasks should be developed and accomplished to introduce in Russia gas transmission technology with use of pressure above 9.8 MPa. Raising the reliability of gas transmission systems is the foreground task when passing to a higher working pressure. This task is to be performed by using a new design methodology including two calculation levels. In this case the second calculation level includes the probabilistic safety analysis.
