Barrus Projects Completes the Third Stage of Autoclave Transport

Barrus Projects representing Kazakhstan and Russia in the Project Logistics Alliance has completed transporting an autoclave from Antwerp to Amursk for the second autoclave line of Amursk Hydrometallurgical Plant constructed by Polymetal.

As part of the first stage, the autoclave was shipped from COEK Engineering’s berth in Geel (Belgium) and delivered to the port of De-Kastri, in Russia’s Far East. The second stage of transportation consisted of the autoclave’s reloading onto a specialized barge on the roadstead of the port of De-Kastri and transportation to Amursk. Click here to read the first stage and here for the second stage. The third and final stage of moving this 1100 MT autoclave was the most difficult to implement and required a coordinated approach from their project teams for two years.

The biggest challenge of this project was the colossal fluctuations in water levels in the Amur river, which do not occur in the central part of Russia. Such drops in water levels can reach 5-7 meters in a very short time. The implementation of the entire project depended on the quality of the solution to solve this challenge. The project team at Barrus Projects managed to develop a unique technical solution. It was a RO-RO berth, designed in a way that guaranteed to unload on the designated dates of the autoclave’s arrival in Amursk, regardless of the water level. A temporary bank protection structure was also designed using two sets of ramps and a transitional support pile, the elevation of which, depending on the actual water level, could be adjusted for RO-RO unloading of cargo.

Their customer entrusted them with turnkey work, including the full scope of surveys, design, and construction of the berthing facility, as well as preparation of the route along with the city of Amursk to the Amursk Hydrometallurgical Plant.

As part of the third stage of the autoclave’s transportation to Amursk, together with the customer, the city, and Amur region Administration, balance holders of communication lines and supervisory authorities, complex and demanding work was carried out:

  • Design and construction of a unique temporary bank protection structure in the form of a RO-RO berth;
  • The access road to the temporary bank protection structure was designed and built;
  • A colossal amount of work was carried out to prepare the route. Temporary widening of the turns’ radii was carried out, a complete repair of the road’s surface along the route was carried out;
  • Design and reconstruction of power lines from 0.4 kV to 35 kV along the route;
  • Design and reconstruction of two heating mains (TM-15 and TM-16) along the route;
  • Work on the restoration and areas of territory improvement affected and modernized during transportation, including additional planting of green spaces in the city of Amursk.

All these works were carried out in full compliance with the requirements of the customer, the сity and district Administration, and taking into account the high social responsibility of Polymetal: all with the minimum possible impact on the quality of life of the residents of Amursk.

Furthermore, Barrus Projects’ own transport equipment was mobilized to Amursk. It included self-propelled modular transporters, which allow for the assembly of the most optimal transport combination for each specific cargo. A rare combination of 28 double-width axle lines was used in this project. That is 448 wheels.

The autoclave was also installed on the foundation using a specially developed technology. We used two hydraulic gantry systems with a lifting capacity of 1100 tons each, which worked synchronously. For the first time in Russia, installation on the foundation was carried out by synchronous actions of two hydraulic gantry systems SBL 1100.

The project was carried out by the Key Point Logistics team, which invited Barrus Projects for the contract work. An over-dimensional heavy cargo weighing 1100 tons was delivered without delays and slightly ahead of the planned schedule, despite all the difficulties of the route and the epidemiological situation. Barrus Projects is grateful to Polymetal for the trust placed in their team and the opportunity to implement such an important project. Barrus Projects is also thankful to its employees and all partners for the successful implementation of such unique tasks.
