Substantiation of methods of improving safety of pipeline gas transportation

Ensuring the operational efficiency of hazardous production facilities throughout their entire service life becomes a formidable challenge associated with coordinating thorough monitoring such facilities, assessing exposure, mitigation and sustainability, taking measures to minimize prevent negative outcomes that can lead consequences, including human fatalities, injuries economic losses. At same time, optimal choice ratio between levels risk costs identification, regulation increase in resource will ensure both reduction minimum failures gas pipeline systems use maximize technogenic safety. The paper proposes methodology for calculation indicators probability emergencies on networks distribution during operation normal emergency situations.
