Discussing a Line of Promising Dredge Ships

April 21, 2010

On April 16, 2010, the first meeting of the Council of River Basin Administrators took place at the Federal Marine and River Transport Agency of the Ministry of Transportation of the Russian Federation.

There, the Prospective Development Director, chief designer of the Marine Engineering Bureau Nikolay Avtutov spoke on a line of dredge ships offered for construction.

At the active debate spoke deputy head of Rosmorrechflot Oleg Shakhmardanov, deputy chief of the Inland Water Transport Administration of Rosmorrechflot Sergey Lednitsky, head of FGU Kamvodput Sergey Kostarev, head of Volgo-Baltic State Basin Authority Vladimir Nikolaev, head of Ob-Irtysh State Basin Authority Sergey Ovchinnikov, head of Lena State Basin Authority Yury Dolzhenko, General Director of the Marine Engineering Bureau Gennady Egorov, and others.

The Council noted that over 90% of ships of the Russian technical fleet has become obsolete and deteriorated; their automation systems do not meet modern requirements, and seaborne machinery servicing requires more personnel to be involved. The average age of river ships approaches to 30-year border and grows further.

Basing on the situation analysis the following arrangements were offered:

  1. In case of heavy-duty multi-bucket dredgers and dredging pumps, the procedure of update and profound retrofit of existing dredgers should be employed complete with maximum possible replacement of obsolete process equipment in accordance with terms of reference for retrofit of multi-bucket dredgers with a productivity rate of 900 and 250 m3/hour, and dredging pumps of 1,500 and 1,000 m3/hour, such terms being developed by NIR.
  2. Construction of nonpropelled dredging pumps without crew spaces, equipped with modern appliances including cutter heads for heavy soils and hydraulic rippers for light soils in accordance with terms of reference for construction of new dredging pumps with a productivity rate of 1,000, 650 and 350 m3/hour, such terms being developed by NIR.

The line of dredge ships offered for construction comprises:

  • Selfpropelled multi-bucket dredger with a productivity rate of 600 m3/hour (basing on a prototype project P36 dredger).
  • Nonpropelled multi-bucket dredger with a productivity rate of 250 m3/hour (basing on a prototype project 92-035 dredger).
  • Selfpropelled dredging pump with a productivity rate of 1,500 m3/hour (basing on a prototype project 1-517-03 dredging pump with guaranteed productivity rate of 1,500 m3/hour at heavy soils when using a cutter head and 2,500 m3/hour at light soils when using a slot nozzle).
  • Nonpropelled dredging pump with a productivity rate of 1,000 m3/hour.
  • Nonpropelled dredging pump with a productivity rate of 650 m3/hour.
  • Nonpropelled dredging pump with a productivity rate of 350 m3/hour.
