As part of the main oil and oil product pipeline systems, there are site facilities with fire and explosion hazardous objects, where lightning protection and grounding systems operate. Previously, materials were published addressing the scope of work to inspect lightning protection and grounding systems (LPGS) at the facilities of Transneft PJSC. Such inspections have been conducted by The Pipeline Transport Institute LLC on a regular basis for more than 10 years. During this time, a number of theoretical studies related to optimization of the technology for LPGS inspection have been carried out, and rich practical experience in performing field work and automating the processing of the obtained data has been accumulated. This article presents the results of the analysis of the state of existing LPGS taking into account the standards under which these systems were designed and constructed, as well as the new regulatory and technical documents. The trends of change in the state of lightning protection and grounding systems of site facilities and line section facilities are analyzed. It is shown that as systematized inspections of the technical condition of these systems are introduced, the culture of their maintenance by operating organizations increases. At present, there is a trend to reduce the number of non-compliances at oil pumping stations, oil depots, as well as block valve stations and other line section facilities. Inspections are carried out on the basis of prospective programs and programs for the planned calendar year.
