On December 14, 2017, at the shipbuilding and ship-repair yard “Nobel Brothers Shipyard”, the motor ship “Severodvinsk” of project 576 “Sixth Five-Year Plan” was lifted for off-season ship repair. This was reported by the press service of the enterprise.

Ships of the "Sixth Five-Year Plan" type are medium-sized dry-cargo ships with four holds with hatch covers, with a double bottom, with an engine room and a superstructure in the stern, a continuation of the series of ships of the "Bolshaya Volga" type (project 11).

The motor ship was built in 1965 at the Romanian plant Santierul Navale Oltenita Santierul Navale Olteniţa.

Characteristics of the vessel: displacement - 2072 tons, length - 93.9 m, width - 13.22 m, draft - 2.8 m, height - 4.8 m.

Nobel Brothers Shipyard LLC is the largest shipbuilding and ship repair company on the Upper Volga, founded in 1907 and specializing in the construction, repair, renovation and modernization of the following types of ships: sea and river tankers for the transport of oil and oil products; sea ​​and river dry cargo ships, designed and built according to European standards, for the transportation of general cargo, international containers, timber, bulk and dangerous cargo; special-purpose vessels, including marine diving and hydrographic vessels, vessels of port infrastructure; special-purpose boats, including rescue boats-booms; hulls of ships of various types, including hulls of modern comfortable yachts.

Justification of the architectural and structural type of the vessel

The choice of a prototype vessel is carried out according to the following criteria:

1. Purpose - dry cargo ship

2. Class of the vessel - О

3. The carrying capacity of the vessel is 2000 tons.

The main features that determine the architectural and structural type of the vessel are: location of cargo spaces, engine room, superstructures along the length of the vessel; constructive type of case; the number of holds and the distribution of the useful volume between them; location and dimensions of cargo hatches; equipping the vessel with cargo devices.

An analysis of the modern experience in the design and operation of cargo ships in early navigation shows that the location of the engine room (MO) and superstructure in the stern, cargo holds in the middle cylindrical part of the hull contributes to both an increase in the intensity of cargo operations and the most rational use of the hull capacity.

However, from a purely shipbuilding point of view, the aft arrangement of the MO and superstructure also has significant drawbacks. So during the course of the unladen vessel has a significant trim to the stern.

The aft position of the wheelhouse impairs the visibility of the boatmaster along the course of the vessel, especially when moving unladen with a bumper, when transporting a significant amount of cargo on deck (for example, timber piles), when moving together with a pushed non-self-propelled section. The location of residential and office premises in the aft superstructure located above the MO, i.e. in the noisiest area of ​​the ship, requires special, sometimes very expensive, constructive measures to reduce noise and vibration to the required level.

Many of the listed disadvantages can be avoided by transferring the superstructure and wheelhouse to the bow of the vessel.

The motor ship of the Sixth Five-Year Plan (Project 576) is an average dry-cargo vessel with four holds with hatch covers and a double bottom. With engine room and superstructure aft. Vessels designed for bulk, bulk, packaged cargo, such as construction crushed stone, sand, coal, paper in rolls, timber in logs.

Project 576 provided for the installation of machines of increased power and wide mechanized sliding covers of holds. Externally, the vessels of Project 576 are distinguished by a higher bow and wide windows of the superstructure. Late vessels have a superstructure with portholes instead of windows.

Determination of displacement and main dimensions of the vessel

Initial data and characteristics of the prototype vessel:

1. Class of the prototype vessel - "O"

2. The carrying capacity of the prototype vessel is 2000 tons.

5. Length of the vessel at design waterline (Lm) - 90m.

6. Width of the vessel at design waterline (B) - 13m.

7. Board height (H) - 4.8 m.

8. Draft when loaded (Tgr) - 2.8m.

9. Number of crew (nc) - 27 people.

10. The coefficient of the completeness of the volumetric displacement - 0.836 t / m 3.

11. Body mass meter - 0.105 t / m 3.

12. Cubic module LBH - 5620m 3.

13. Meter of mass of mechanisms (p) (p = Rm / N) - 0.099 kW.

Рм - mass of mechanisms

When setting the tasks of the diploma project, an analysis of the promising trends in the development of the river fleet was carried out, which made it possible to choose a vessel of project 576T as a prototype vessel. This is a twin-screw pusher tug, the purpose of which is to push and tow dry cargo trains and barges, as well as oil barges.

Comparison of the parameters of the power plant of the prototype ship with modern counterparts showed the feasibility of replacing its main engines. When choosing the main engines, the methodology developed at the SEU Department was used. As an alternative, the 6ChRN30 / 38 engine manufactured by the Kolomna plant and 6ChN20 / 28 manufactured by the Finnish company Vyartsilya were considered. The comparison was made according to a complex quality indicator. As the main engine, taking into account the required power providing a given tractive effort, an increased speed, a four-stroke non-reversible 6ChN20 / 28 diesel engine with an effective power of 990 kW at a rated speed of 1000 rpm KV was selected.

Poster 6 shows a general view of the designed exhaust gas catalytic converter, which includes a TAPP, an oxidation stage for incomplete combustion products and a nitrogen oxide reduction stage.

Measures to improve the environmental performance of diesel engines are usually implemented in conjunction with work to improve fuel efficiency and reliability and include low-toxic adjustments of fuel equipment (for example, reducing the fuel injection advance angle), intercooling of charge air, shutting down part of the cylinders at low loads, using water-fuel emulsions and various and different fuel additives (for example, when loading the product - 42).
Motor ships of the types LOS (project 587) and KAMGES (project 576 T) are large deck tankers with an engine room and a superstructure in the stern.
Tankers of project 576T (type KAMGES or Tanker 34) are structurally close to projects 576 (type Sixth Pyatiletka), from which they differ in an increased long hull and a raised wheelhouse. Tankers of project 587 (type Los or Tanker 34) with a similar hull have a higher bow, a modified superstructure and a chimney.
