Investigation of the fire danger of the main oil pumping station GNPS-1 “Taishet” by LLC “Transneft-Vostok”

Abstract

Statistical data and equipment parameters are used to analyze accidents caused by the termination of the receipt of electricity and heat, technical failures, control failures and human errors. The main reasons for the damage of technological equipment are determined on the example of the head oil pumping station GNPS-1 “Taishet” in connection with fire propagation scenarios; the ways of solving the problems are described. Exceeding the design loads while maintaining the design strength of the equipment causes excessive mechanical effects. An example of the mechanical action is an increase in operating pressure in technological equipment. Violation of the integrity of the structural material of pipelines and technological devices occurs as a result of electrochemical corrosion. In the presence of moisture on the surface of structures, a film containing dissolved air and atmospheric impurities develops. The use of corrosion-resistant materials and the insulation of the inner and outer surfaces of pipelines with anticorrosive coatings increase their reliability. The most dangerous scenarios of accidents, fires, and explosions are accidents at three sites: in the tank farm, at the main oil pumping and back-up pumping stations. The scenarios for the development of an accident of the technological equipment and pipeline sections will allow us to determine the distribution of fire risks on the territory of the facility and beyond its borders, including assessing the magnitude of fire risks in order to develop measures to reduce it.
