This November, Transneft will commission a new oil pump station (PS) #29 currently under construction not far from Arkhara settlement in the Amur Region, as part of increasing the delivery capacity of the second phase of the Eastern Siberia – Pacific Ocean Pipeline System (ESPO-2). The Company will also set to the extension of the operating PS-27.
Chief Engineer of Regional Oil Pipeline Directorate (RPD) “Belogorsk” Anton Shenderov informed that an active stage of commissioning works is already under way at PS-29.
“The system is due to be launched in Q4 of this year, tentatively in November. After the station is put into operation, the delivery capacity of ESPO-2 will increase by 36 million tonnes of oil a year,” he pointed out.
PS-29 will be a booster pump station at the 3,461st km of the ESPO pipeline system. The construction and assembly works commenced in August 2015. Since then a trunk oil pump station has been erected along with a control room, fire station, fire water tanks, wastewater biotreatment station and other facilities.
“The facility is 90% ready with 300 personnel involved in the works. Going on now are individual tests of the equipment, commissioning and landscaping works. The station’s main function is increasing the oil pipeline’s delivery capacity,” said Aleksandr Polishchuk, Head of Construction at “Eastern Siberia – Pacific Ocean” Project Management Center, LLC.
In his words, last year delays were caused by weather conditions. Steady rains disrupted excavation, foundation and corrosion protection works. “We caught up with the schedule by involving extra manpower and technical resources,” explained the construction management chief.
The trunk pump station comprises four NМ 7000-250 oil pumps with capacity standing at 5,145 m3/h. The new PS, increasing pressure inside the oil pipeline, will maintain a necessary delivery volume of oil that arrives at this section from upstream PS-27 (Ekaterinoslavka, Amur Region) and then flows downstream to PS-30 (Obluchye, JAR).
Sergey Zakharov, head of the mechanical process section, has commented that as of today hydro tests (strength and leakage tests of the pumping equipment, pipeline and manifold) have been completed.
“As for the mechanical part, the pump station is 85-90% ready, and construction works are 90% complete, that’s for sure. I believe, in two months from now we’ll feed the oil to the system and start pilot runs, checking vibration, pressure, flow and temperature parameters,” Mr. Zakharov pointed out.
In the days to come the new station will be connected to the united power grid: a 220 kV outdoor switchgear is fully ready. For now, all facilities of PS-29 are powered by three diesel power plants.
“The outdoor switchgear is an electric artery of the entire station: voltage will be transmitted over two overhead lines: from Nizhnebureyskaya HEP and Arkhara substation. Pre-commissioning activities are in full swing now and in late August we plan to energize the facility,” informed power engineer at PS-29 Georgiy Golubev.
The station is half staffed, with 32 specialists out of 64 already employed; these are mainly residents of Arkhara District. As was noted by Timur Yumachikov who came to the Amur River Region from Tyumen to take charge of the new PS, till the end of September the HR managers will fully complete the staffing.
“The station will likely be put into operation this November. As we speak, the potential employees pass medical examinations and meet with HR managers. The local school of power engineering partly provides us with personnel; nevertheless, our work is rather specific, so personnel of all trades attend skill-raising courses. We’ll also start training a new generation of specialists at local schools. Next year we’ll help to outfit the classrooms of STEM disciplines, providing them with labs and all essential equipment,” shared the station chief.
They have already started forming a volunteer fire brigade at PS-29. The trunk firefighting station is equipped with dosing tanks, foam firefighting pumps and auxiliary water firefighting pumps.
The PS is fully protected automatically. In addition, the facility is also complete with two fire trucks.
A 16-unit residential building for PS-29 employees in need of housing has already been constructed and populated in Arkhara settlement (35 km away from the station).
Right after PS-29 is launched, works to extend PS-27, located in Belogorsk District of the Amur Region and functioning since 2012, will commence.
In the words of RDP Belogorsk’s chief engineer, the PS-27 extension implies construction of an oil storage tank farm. This will upgrade its status from a booster pump station to a pipe-end PS on the ESPO-2 trunk pipeline.
“The plan calls for the construction of two tanks holding 50,000 m3 and two more holding 5,000 m3 for emergency oil spill. A booster station will also appear. In this way the oil reserves will be accumulated between Skovorodino and Khabarovsk,” noted Mr. Shenderov.
As of today, Belogorsk RPD still does not have oil storage tanks which are needed for uninterrupted oil supply in case the flow speed drops at some stage.
“In the fourth quarter we plan to sign a contract for construction and assembly works to extend PS-27, and in late December of this year the contractor must enter the site. We’ve already started delivering metalwork in order to save time,” commented chief engineer of Belogorsk RPD.
All PS-27 extension works will be completed in 2019. In the following years the plan also calls for a gradual increase in the capacity of ESPO-2. Our plans include the construction of PS-32 in the Jewish Autonomous Region as well as PS-23 and PS-26 in the Amur River Region.
