Temporary PIG traps were disconnected at the Voronezh – Belgorod PPTP’s underwater crossing of the Voronezh River. A gate valve was repaired at the tank farm of Nikolskoye line operation dispatcher station (LODS). The repairs were carried out without changing the oil transportation mode.

The works were carried out during 160 hours in Samara, Ulyanovsk and Penza Regions. The purpose of the scheduled works was to increase the reliability of transportation of oil and petroleum products through the system of trunk pipelines.
Petroleum products transportation was resumed in accordance with the schedule. The pipelines are functioning under the normal protocol.
