The demand for river dredgers in Russia is estimated at 74 units, cranes and boats for bottom-cleaning - 26 units, hopper barges - 27 units, Gennady Yegorov, Director General of Marine Engineering Bureau, said yesterday at the Hydraulic Engineering Structures and Dredging Congress organized by media group PortNews (7-8 February 2018).
According to him, it is economically efficient to build non-self-propelled suction dredgers with no living accommodation for the crew. They should be fitted with state-of-the-art equipment including cutters for heavy ground and hydraulic devices for light soils. Each new dredger should also have a receiving ship, an anchor boat, 2-3 non-self-propelled hopper barges and the same number of non-self-propelled hopper barges with pusher tugs.
He considers it reasonable to use the procedure of Russian River Register for using the decommissioned ships for construction of new dredgers. Taking into consideration the demand of different basins Russia will require dredgers of about 6 different types.
