Trest Zapsibgidrostroy LLC (general contractor for hydraulic engineering works under Gazpromneft-Omsk Refinery modernization project) says it has completed the construction of a transshipment facility under the project on reconstruction of Omsk Refinery.
According to the statement, application of the advanced technology for construction of retaining walls with the use of welded pipe piles and many years' experience of the company allowed it complete this hi-tech project within a year.
To accept heavy weight equipment and cargo needed for construction of Omsk Refinery’s hydrocracking facility, a new transshipment facility has been built on the bank of the Irtysh river near Nikolayevka settlement. The facility includes a berth for Ro-Ro ships and a berth allowing for handling of construction cargoes by both crane and Ro-Ro method as well as for delivery of large-capacity equipment by special transport to the point of transshipment. With its length of 80 meters, width of 15.5 meters and reinforced foundation the new facility is able to take over bulky cargo of up to 1,000 t. To ensure higher load-bearing capacity of the facility and its safe operation over a long period of time, Trest Zapsibgidrostroy applied the technology of filling the welded pipe piles with reinforced concrete. The research confirms that filling the welded pipe piles with reinforcing steel cage and concrete multiplies the structural stiffness and load capacity of the facility.
Besides, the company’s patented interlock was applied during the construction. Pipe piles of Trest Zapsibgidrostroy feature considerable advantages over their foreign counterparts in terms of metal use efficiency coefficient, geometrical dimensions, resistance to corrosion and ease of handling at construction sites. All these factors ensure full import substitution.
The facility offers two types of handling at the berths: a vessel comes to a berth where it is unloaded by cranes or unloading is performed with the use of mobile hydraulic multiaxial hoist equipment. Each axle can bear a load of 400 t, therefore a road from the storage ground to the refinery was under repair simultaneously with the construction works. The road can be used for transportation of equipment of 800 t. To ensure the required characteristics of the road, Trest Zapsibgidrostroy applied a special technology with metre-deep layer of sand, a layer of crushed stone and three layers of asphalt. Minimum width of the road is 7 m, maximum - 12 m, length - 950 m.
IAA PortNews earlier told about unloading of heavy weight equipment at the new facility. 6,000-tonne cargo intended for reconstruction of Gazpromneft-Omsk Refinery was unloaded on 19 October 2016. More equipment intended for the refinery will be delivered by water in 2017-2019.
Trest Zapsibgidrostroy LLC founded in 1977 is a Russian company focused in designing and construction of hydraulic engineering structures and transport infrastructure facilities; construction of embankments, shore protection facilities, cargo and passenger berths , dams; construction of road junctions and roads, retaining walls for both industrial and civil engineering purposes; production and supply of the patented and certified steel pipe sheet piles and steel works.
At present, Trest Zapsibgidrostroy is a diversified production structure comprising six separate construction and design units in Surgut, Nizhnevartovsk, Tyumen, Novosibirsk, Samara and Moscow.
