Mandryk O. The development of scientific principles of ecological safety level enhancement in natural gas transportation.

The object of study is the process of forming and changing technogenic state of the environment in the area of gas transportation infrastructure impact. The subject of research is the scientific substantiation of the gas transportation infrastructure impact evaluation on the environment and its reduction. The methods of research are the finite elements, system analysis with the aid of experimental methods of fracture mechanics, the strength and crack resistance characteristics of steel gas mains were examined; by using the methods of physical, mathematical and computer simulations the evaluation of influence of the gas mains failure scale on the formation of pollution area was done. The level of introduction of the developed 20-channel analogue-digital transducer (ADT) for determining stress and strain state of large diameter pipelines was introduced at the Department of Gas Mains “Prykarpattransgas”.
