The industry system for assessing the conformity of the main types of products used by Transneft has been operating since 2004 and is implemented on the basis of the Research Institute of Pipeline Transport of Transneft Research Institute. Conformity assessment shall be carried out for products of producers ensuring the technological processes of oil and petroleum products transportation and safety of facilities of oil trunk pipelines and petroleum product pipelines, including products operated under excess pressure of oil and petroleum products.As part of the implementation of this area of activity, the institute solves the following tasks:— expert examination of technical documentation of products;— participation in factory tests of products;— conducting tests of products on their own at the Research and Development Center of NII Transneft LLC (Ufa);— participation in the inspection of the production of products. In turn, Transneft has defined a list of the main types of products that are subject to mandatory conformity assessment and inclusion in the ORP Register, after which they are allowed to be used at Transneft’s hazardous production facilities, as well as developed its own industry regulatory documents of the type general technical requirements that take into account the uniqueness of the operating conditions of the equipment. Management of equipment reliability at different stages of the life cycle in an oil transportation enterprise represents a complex multilevel system of interrelated scientific, methodological and organizational and technical measures that directly or indirectly affect the reliability of equipment.Within the framework of the studies carried out by the specialists of Transneft Research Institute, more than thirty such measures were analyzed for direct or indirect impact on the reliability of equipment, including incoming control of equipment, factory, bench, resource, laboratory tests, production inspections, technical supervision of manufacturing, construction control of installation, diagnostics, maintenance, repairs, development of industry standards and other procedures. The variety of such processes makes up the system reliability of hazardous production facilities for pipeline transport of oil and petroleum products. The heterogeneity and sometimes redundancy of such processes negatively affect both operating organizations and equipment manufacturers.
