PMC ESPO (a subsidiary of Transneft) commenced hydraulic testing in the linear portion of the pipeline offshoot ESPO PS – Komsomolsk Refinery.
The tests will consecutively be held at five sections into which the oil pipeline has been divided. In May 2017 it is planned to conduct hydraulic tests in two sections (233.2–293km, and 0.36–76.3km) wherein the pipeline welding has been completed. As of now, builders of the linear portion have welded into a single line more than 280 out of 293 kilometres of the oil pipeline. Other sections of the pipeline will be tested for strength and leakage after installation and welding is completed.
The testing is comprised by two phases. The water-filled oil pipeline will first be exposed to hydraulic load for 24 hours (the pressure above 11MPa inside the pipe, several times higher than the rated pipeline pressure). Then the pressure will be reduced to check the pipeline for leakage for 12 hours. Professionals of PMC ESPO, Transneft Far East and Transneft Supervision will control the gauge and meter readings and visually observe the pipeline. By commencement of tests in the linear portion PMC ESPO successfully completed testing of all underwater crossings.
“Pipeline offshoot ESPO PS – Komsomolsk Refinery” projects envisions construction of 293km of the linear portion, a pipe-end PS with the tank fleet of 80,000m3, two booster pump stations and external power supply facilities. The project implementation will guarantee oil delivery to the Komsomolsk Refinery via the oil trunk pipeline system of Transneft, in the volume of up to 8 MTPA. The oil pipeline offshoot runs in the Amursk, Komsomolsk, and Solnechny districts of Khabarovsk Region. The route features a multitude of swampy and flooded sections; overall, 139 water obstacles were surmounted, including four major rivers of Selgon, Kharpi, Alkan, and Khevchen.
