ZALA AERO completed a set of aerial patrol operations for UETP-NKNKh LLC

A set of works on air patrolling of main ethylene pipelines for the needs of OOO Nizhnekamskneftekhim Ethylene Pipeline Management (OOO UETP-NKNKh - a subsidiary of PJSC Nizhnekamskneftekhim) on the territory of the Republic of Tatarstan and the Republic of Bashkortostan was completed.

Aerial patrols were carried out using ZALA unmanned aerial systems equipped with professional aerial photography and high-precision geodetic equipment (GNSS). The main tasks were to detect violations of protection zones and minimum distance zones, as well as to identify leaks on the main ethylene pipelines, construction and installation works, illegal passages and crossings over the ethylene pipeline route, landfills, etc. The main objectives of the patrols were to detect leaks on the main ethylene pipelines.

In the course of the works, long-term identification signs for the Customer's production needs were laid near the route of the main ethylene pipeline.

Based on the obtained photographic materials and satellite measurements, ZALA AERO specialists produced and transmitted digital orthophotomaps of the area with geodetic georeferencing at a scale of 1:500. A report was prepared and transmitted, which contained identified violations, a map and a list of land users located in protection zones and zones of minimum distances.

The total length of aerial photography with geodetic support of the Nizhnekamsk-Kazan and Nizhnekamsk-Ufa-Sterlitamak-Salavat ethylene trunk pipelines was more than 750 km. The data obtained will help to effectively monitor the technical condition of the main ethylene pipelines that transport raw materials for the largest petrochemical enterprises Kazanorgsintez PJSC and Nizhnekamskneftekhim PJSC.
