The Analysis of Ecologically Safe Operation of Oil Pipelines by Methods of the Stochastic Theory of Similarity

Abstract

In article it is shown that in the analysis of conditions of environmental safety of the main oil pipelines (MOP) with use of methods of the stochastic theory of similarity, it is necessary to consider not only the MNP design-technology parameters, but also various chemical mass-exchanged processes, for example, corrosion (oxygen, sulphurous and chloric corrosion), influencing changes of structural elements in time and space. For these reasons, dependences between parametrical criteria of similarity and their communications with stochastic criteria of similarity are the basis for the developed model. Comparative analysis was carried out by results of a research more than 70 emergency situations, at transportation of oil through the main pipelines of 18 companies. In parameters of accidents criteria ratios between the factors affecting environmental safety of MNP are received. It is established that average specific intensity of accidents on routes of the sites of the oil pipeline equipped adjustable and unregulated nature protection to constructions and the equipment and also without them, correspond as 1:4.9:83.5. It is shown that a ratio of costs of compensation of ecological damage in case of accidents on routes of the same sites of the oil pipeline equipped adjustable and unregulated nature protection to constructions and the equipment and also without them approximately correspond as 1:1.9:7.5.
