Transneft Druzhba has completed planned works at the Kuybyshev – Unecha – Mozyr-1 oil trunk pipeline (OTP). The goal was to increase the reliability of oil transportation.

At the Lopatino – Krasnoselki looping, a substandard tee and two block valves were replaced with gate valves.
After the revamping, the pressure process pipeline of the Stanovaya OPS and the supply process pipeline at the Kuznetsk OPS were connected.
