Employees of Ishim and Omsk Regional Oil Pipeline Directorates of Transneft Western Siberia has completed scheduled work at Company's operating facilities in two regions of Western Siberia
Preventive and scheduled repairs were performed to ensure uninterrupted operation of the operating infrastructure of the company.
During the scheduled shutdown of oil transportation specialists dismantled four non-operational pressure taps at the TON-2 oil trunk pipeline (OTP), two stop valves with bypass line sections and two dead-end sections at the Ust-Balyk – Omsk OTP. Due to the end of the service life at the Abatskaya oil pumping station (OPS), four stop valve units of the pipeline surge relief system were replaced.
Repair teams cut out duplicate gate valves at the process pipelines of the Omsk line operation dispatcher station (LODS) and the Moskalenka LODS. Also, in the course of the scheduled work the workers carried out installation of a gate valve of the supply pipeline of the heating plant under construction to the pipelines of the Moskalenka pump house LODS. The construction of the heating plants is conducted as part of Transneft Western Siberia’s Technical Upgrading, Revamping and Overhaul Programme. The heating plants will be equipped with two boilers with improved energy-saving characteristics due to reduced specific fuel consumption for thermal energy generation. The scheduled annual savings in physical terms will be about 14 tonnes of oil equivalent.
In addition, as part of the scheduled work at the Omsk LODS, the main pump unit (MPU) No. 2 was shut down for subsequent replacement.
In total, about 120 people were involved in the works.
Transportation of oil via oil trunk pipelines has been resumed as scheduled and is now functioning under normal conditions.
