Abstract

The current level of technology development concerning technical, informational and organizational services in the field of the linear part of trunk pipeline technical condition diagnostics has significantly increased the control reliability and productivity [1]. Thus, tens of thousands of defects, including those of an operational nature, are detected annually only via in-line inspection. Since the start of the oil and gas industry development, the oil transportation system has undergone many changes [2]. The main type was pipeline transport, the facilities of which ensure the transfer of more than 85% of the oil produced in Russia. Such indicators are conditioned by a number of reasons. Here are some of them: the relatively low cost of pumping, short and uninterrupted delivery of products, the ability to transport several types of oil products at the same time, and others. The main pipelines are designed so that oil from the fields passes to main consumers and refineries through the main intermediate consumption points, as well as commodity products are exported [3]. The timely implementation of mandatory and recommended works will ensure the safety of the entire oil transportation system, and will also serve to develop the potential of this economic sector of the state. The system for oil, gas and oil product transportation is the combination of trunk pipelines.

Introduction

The unified system of main oil pipelines (MOP) is the largest in the world, covering such a diverse territory. The development plan takes into account the need for modernization and repair of operating systems, the bulk of which was built more than 20 years ago [4]. The timely implementation of mandatory and recommended works will ensure the safety of the entire oil transportation system, and will also serve to develop the potential of this economic sector of the state. The main activities of oil transportation companies are the following ones [9]:  Provision of services in the field of transportation of oil and oil products through the trunk pipeline system.  Carrying out preventive, diagnostic and emergency repair work on trunk pipelines.  Coordination of activities for the integrated development of trunk pipeline network and other pipeline transport facilities.  Interaction with pipeline enterprises of various countries on the transportation of oil and oil products in accordance with intergovernmental agreements.  Participation in scientific, technical and innovative development issue solution concerning pipeline transport, the introduction of new equipment, technologies and materials.  Organization of work to ensure environmental protection in the areas of pipeline transport facility location. Oil, gas and oil product transportation system is a combination of trunk pipelines. An extensive network of such pipelines (oil, gas and oil product pipelines) is the main way of oil (99%), oil product (50%), natural, oil and artificial hydrocarbon gas (100%) delivery from the regions of their production to internal and external consumers [5]. The main pipelines, unlike domestic, local and technological, are characterized by a long length, high throughput and connect the supplier of oil and gas products to the consumer. Due to the long extent, the pumping is carried out not by one, but by several stations located along the highway. The operation mode of such pipelines is continuous (short-term stops are random or associated with repair and restoration work) [5].
