Transneft Volga Region has received positive conclusions from the Main Department of State Expertise Federal Autonomous Institution (Glavgosexpertiza of Russia) for the construction of a pipeline clean-up and inspection tools trap (PIT trap) at the Saratov – Kuzmichi oil trunk pipeline (OTP).
The facility construction is planned at the Kuzmichi line operation dispatcher station (LODS) in Gorodishche District of Volgograd Region in accordance with the technical upgrading and revamping programme of Transneft Volga Region. The new PIT trap will be built with the subsequent dismantling of the existing one. The goal is to improve the reliability and energy efficiency of process equipment, to ensure the environmental and industrial safety of oil trunk pipelines.
The PIT trap is designed for receiving and recovering pipeline clean-up, inspection and batching tools in the flow of transported oil.
The PIT trap will be mounted with the installation of an underground drainage tank, an overhead cable tray, a searchlight tower with a lightning rod. In addition, the project provides for the installation of power supply systems, electrochemical protection for corrosion prevention, as well as control and monitoring equipment, the use of stop valves with electric drives for remote control.
The design documentation provides for the improvement of the software of the Unified Supervisory Control System of the Samara regional control centre, as well as the centralised emergency control automation system and the leakage detection system of the oil pipeline section.
The design documentation was prepared by Giprotruboprovod Institute for Trunk Pipeline Design (Giprotruboprovod). Experts from Glavgosexpertiza of Russia concluded that the technical part of the design and engineering documentation complies with requirements of current Russian regulatory documents; a positive conclusion was issued on the project.
The project implementation for the PIT trap site construction will begin in 2022. Construction and installation works will be carried out without changing the existing oil transportation scheme.
