Specialists of Transneft Western Siberia have commissioned four new tanks at Omsk line operation dispatcher station (LODS).
The construction of the tanks was carried out as part of the programme of technical upgrading and overhaul of the Company’s operational facilities for the period of 2014 – 2020.
Tanks Nos. 9, 10, 11 and 12 with the total volume of 40,000 cubic meters designed for the acceptance and storage of diesel fuel. The applied design solutions ensure their safe operation for 50 years after completion of the construction; the interval before the first repairs is 20 years.
A large-scale set of works was performed during the construction. In addition to the construction of the tanks, foundation was laid for technological gate valves and a load compensation system. An overhead cable tray and rooms with electrically driven valves were built, wells were constructed for fire-extinguishing systems and industrial waste and storm water sewage. Lightning rods, searchlight towers and pipeline gate valves’ service areas were organised. A screen was arranged inside the dyking.
The tanks are equipped with automatic systems of water cooling and subsurface firefighting with low expansion ratio foam in order to automate operational processes. Remote measurement of the level and the temperature of petroleum products are also provided for. Mechanisms of remote control of the upper permissible level in tanks, their filling and emptying rates were implemented. The tanks are equipped with a system for automatic closing of the main casing gate valves, measuring the parameters of cathodic protection stations.
S345 grade steel was used for the manufacture of the main constructions of tanks – metal sheets for walls, bottom’s edges, manhole and nozzles’ rings. Its advantages include homogeneity of the composition and high strength properties. It is used in critical structural elements that are subject to dynamic and variable force effects during operation.
Artem Fedorov, Deputy General Director for Operation of Petroleum Products Trunk Pipelines at Transneft Western Siberia, noted that the construction of new tanks at Omsk LODS is an important part of systematic modernisation of the technical infrastructure for petroleum products transportation.
“The issue of improving the operational and technological characteristics of petroleum products trunk pipelines is particularly relevant. In-line inspection of PPTPs and revamping of the line part are carried out regularly, telemetry and automation tools are introduced, technical upgrading and overhauls of operational facilities are carried out. Their goal is to ensure a high level of reliability and compliance of the technical condition of the facilities with regulatory standards as well as requirements of environmental and industrial safety,” said Artem Fedorov.
Currently, four more tanks are being built at Omsk LODS for storage of petroleum products.
