As a unified basis for the construction of landing stages, we use four types of reinforced concrete hulls.

Shipyard in Kolomna

Around the world reinforced concrete inland waterway vessels were mostly built during the first and second world wars – they were small dry cargo barges. This was related to the lack of steel, the lack of highly qualified workers and transport vessels during the war. Success in the construction of reinforced concrete vessels was achieved by such countries as England, USA, Germany, Italy, Denmark, Sweden and Norway. But despite the fact that reinforced concrete vessels have proven themselves beneficial (low operating costs, simple structure), their construction has practically been stopped during the second half of the XX century and continued only in the Soviet Union. At the moment reinforced concrete has found application in the construction of small pontoons (not more than 8m x 10m) used for houseboats and moorings in Netherlands and USA.

During the postwar years in the Soviet Union there existed five shipyards that specialized in reinforced concrete shipbuilding. To date, unfortunately, only two of them have remained – one in Russia and one in Ukraine.

Over the past 25 years Russian river fleet has fallen into disrepair, in connection to this, in recent years there has been a steady interest in the revival of the Russian shipbuilding industry. And if the shipyard specializing in steel pontoons is relatively easy to restore, the one specializing in reinforced concrete base requires not only large capital investments, but also enough amount of good specialists, who unfortunately are almost gone from the market today.

In 2011 our company made a significant step in its quality development and started to incarnate the plan of independent producing of modular reinforced concrete hulls for new floating objects. To reach this goal in the summer of 2012, the company purchased a plot of land on the Oka River near the Kolomna city and started building its own shipyard. In April of 2013, began the manufacture of the first composite hull of the size 72x16 m, consisting of three modules.

At the moment, the production capacity of our shipyard is 10-12 modules per year. Capability of the production area in Kolomna allows us to organize the construction of the second and third stocks that will provide an increase in productivity of up to 30-40 modules per year.

We apply the principle of modular construction, that is the vessel is assembled from modules of the 24×16 m size. Together there can be assembled up to 4 modules, which are manufactured on the stocks and docked in the water.

This does not mean that we can only make vessels of the sizes specified above. Preliminary calculations show that the length of the ship can reach 130-150 meters, while the width unfortunately is limited by the width of gateways.

The company have also patented a "without stock" method of construction - "Patent from 06.12.2012 on the application № 2011153101.11 (079978)", which greatly increase the chances of the shipyard. This technology will provide a simple and relatively quick way of building floating vessels directly on the customer's premises.

To ensure the quality control of welded joints and concrete at the shipyard the company established a laboratory with modern measuring equipment that allows to constantly monitor the technological norms and control the quality of products.

The laboratory carries out the following list of works:

  • measuring control of welded joints;
  • radiographic inspection of welded joints;
  • radiographic inspection of field joints welded connections;
  • radiographic inspection of welded joints in welder qualification under the supervision of the Russian River Register;
  • flaw detection of reinforced concrete hulls;
  • concrete strength evaluation in the finished designs.

The laboratory fits advanced equipment for non-destructive testing and the specialists that work there have certificates of recognition given by the Russian River Register. The company's experts have extensive experience in the field of non-destructive testing of welded joints and concrete quality control in the finished designs. Product quality is an integral part of our company.
