Eastern Siberia – Pacific Ocean Project Management Centre (PMC ESPO, a subsidiary of Transneft) has finished the assembly of metal structures for oil storage tank No. 9 with the capacity of 50,000 m3 (VSFRT-50000) at Tayshet initial pumping station (IPS)-1 in Irkutsk region.
The construction is underway within the scope of the project for the extension of the ESPO PS at the Tayshet IPS – Skovorodino PS section (ESPO-1) up to 80 MTPA.
PMC ESPO commenced the construction and installation in November 2017. A construction pit was dug, a pile foundation (consisting of 1,421 piles, each 13 metres long) was made, electrochemical protection cable and the water repellent layers were laid. After the foundation was ready, the builders started welding the metal structures of the tank’s bottom and walls and assembling the floating roof. At this phase, each joint was tested multiple times and the verticality of the entire structure being assembled was controlled.
Since 20 April, primary survey of the assembled steel tank will start, as an additional control measure. It will last nearly a month, during which professionals will inspect the tank’s foundation and metal structures and take geodesic measurements (laser scanning and levelling) of the oil storage.
The tank’s hydraulic testing will be the final stage of ensuring the strength of its steel structure; the tank will be put into operation based on the test results.
The project “Extension of the ESPO PS up to 80 MTPA” envisages the construction of six new PSs in Irkutsk Region and revamping 15 existing ones, the expansion of the tank farm capacity by 50,000 m3 and the construction of external power supply facilities. The PSs No. 3, 6 and 9 were built during Phase I. the construction of the PS No. 2, 5 and 7 was launched in December 2017. Upon the completion of the project for the extension of the ESPO PS up to 80 MTPA, the Tayshet IPS – Skovorodino PS section will have 21 functioning pumping stations.
