The completion of works on air patrolling of main ethylene pipelines for the needs of Ethylene Pipeline Management Nizhnekamskneftekhim LLC (UETP-NKNH LLC - a subsidiary of PJSC Nizhnekamskneftekhim) in the Republic of Tatarstan and the Republic of Bashkortostan.
Aerial patrols were carried out using ZALA unmanned aerial systems equipped with professional photo cameras and high-precision geodetic equipment (GNSS). The main tasks were to distinguish violations of security zones and zones of minimum distances, as well as to identify leaks on main ethylene pipelines, construction and installation works, illegal travel, and crossings through the ethylene pipeline route, landfills, etc.
In the work process near the route of the main ethylene pipeline, long-term identification marks were laid for the production needs of the Customer.
Based on the obtained photographic materials and satellite measurements, ZALA AERO specialists drew and sent digital orthophoto maps of the terrain with geodetic reference at a scale of 1:500. The final report contained the identified violations, a map, and a list of land users located in security zones and zones of minimum distances.
The total length of aerial photography with geodetic support of the main ethylene pipelines "Nizhnekamsk-Kazan" and "Nizhnekamsk-Ufa-Sterlitamak-Salavat" was more than 750 km. The data obtained will help to control the technical condition of the main ethylene pipelines, through which raw materials are transported to the largest petrochemical enterprises of Kazanorgsintez PJSC and Nizhnekamskneftekhim PJSC.
