CONCRETE SHIPBUILDING

The startup PLAVBETON is focused on design and construction of self-propelled concrete ships of any purpose and displacement based on the replacement of the main structural material of ship hulls - rolled steel for the concrete reinforced with composite (composite concrete or c-concrete). There are well known problems of steel shipbuilding: - Corrosion of a steel hull increases ship operating costs up to 20% of the cost of the new ship; - The standard service life of a steel ship is only 30 years; - Construction of steel hulls is very expensive and in any case, their cost exceeds the cost of ferro-reinforced concrete ships by 20%; - The using of steel as the main structural material in shipbuilding leads to significant energy costs and relevant harmful emissions into the atmosphere of steel production, processing and logistics; - As the process of processing of steel products is complex steel ships are built at only shipyards, the number and capacity of which are limited; And so on. As to composite shipbuilding prices of composite hull which is more than price of concrete hull in 2 times, very sophisticated technology of shipbuilding, a risk of composite hull fire, possibilities for building ships of limited ship displacement and others. We to solve the above problems as concrete ships of any purpose and displacement allow the followings. Reducing building costs of a concrete ship and her operation up to 100% of the price of a new similar steel ship; Besides we increase the a ship life in three times (100 years); Then the followings: Any concrete ships can be built outside of currently shipyards. The energy required for concrete ship hull manufacture and concrete ship operation minimum in 100 times less in comparison with the similar steel ship and therefore the similar reduction of harmful emissions; The providing of cyclic economy for life cycle of a ship; The providing to dispose ash dumps of coal power plants. and so on.
