The article is devoted to the consideration of the complex of works on the establishment of a protective zone of the gas pipeline-a plume. For linear structures that act as an element of the engineering and transport infrastructure of the country, there is a need to establish security zones. The main purpose of security zones is to ensure the safety of facilities and create the necessary conditions for their operation. The object of the study (gas pipeline-plume) is located on the territory of the Yamsoveisky oil and gas condensate field, Purovsky district, Yamalo-Nenets Autonomous Okrug. As a research methodology, the article presents a technological scheme formed on the basis of practical experience and regulatory legal regulations presented in legislative acts of various levels. The technological scheme reflects the stages of work on the establishment of the boundaries of the security zone. During the research, each of the stages is considered on a specific example. Based on the results of the preparatory work, a list of necessary documentation is provided, which forms the basis for subsequent field and desk work. Topographic and geodetic works are presented, including the equipment used (geodetic instruments and software). The processing of the results obtained and the formation of a description of the location of the boundaries of the security zone refers to the desk stage of the boundary setting process. A ready-made package of documents signed with an electronic digital signature, in XML file format, is submitted to the rights registration authority through the multifunctional center (MFC). The result of the establishment of the boundaries of the protected zone is a notification of the entry of information about it into the unified state register of real estate. In the course of the study, the features of the establishment of protective zones for gas pipelines-plumes located in inter-settlement territories were determined. The article also lists the imperfections of the technological process of establishing the boundaries of security zones and offers recommendations for their elimination.
