When setting the objectives of the diploma project, an analysis of promising trends in the development of the river fleet was carried out, which made it possible to select a Project 576T vessel 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.

A comparison of the parameters of the power plant of the prototype vessel with modern analogues showed the feasibility of replacing its main engines. When selecting the main engines, a methodology developed at the Department of Electrical Power Engineering was used. As an alternative, the 6ChRN30/38 engine produced by the Kolomna Plant and the 6ChN20/28 engine produced by the Finnish company Vyartsilya were considered. The comparison was made using a comprehensive quality indicator. As the main engine, taking into account the required power to provide a given traction force, a high-speed, four-stroke, non-reversible diesel engine 6ChN20/28 was selected, having an effective power of 990 kW at a rated rotation speed of 1000 rpm.

Poster 6 shows a general view of the designed exhaust catalyst, which includes TAFP, an oxidation stage for products of incomplete combustion of fuel and a nitrogen oxide reduction stage.

Measures to improve the environmental characteristics of diesel engines are usually implemented in conjunction with work to improve fuel efficiency and reliability and include low-toxicity adjustments of fuel equipment (for example, reducing the fuel injection advance angle), intermediate cooling of charge air, shutdown of some cylinders at low loads, and the use of water-fuel emulsions and various and various fuel additives (for example, when adding product - 42).
Motor ships of the LOS (project 587) and KAMGES (project 576 T) types are large deck tankers with an engine room and a superstructure in the aft part.
Tankers of Project 576T (type KAMGES or Tanker 34) are structurally close to Project 576 (type Sixth Five-Year Plan), from which they differ in the increased length of the hull and the raised deckhouse. Project 587 tankers (Los or Tanker 34 type) with a similar hull have a higher bow, modified superstructure and chimney.

Well, that's the whole selection. Fits in four parts.

Justification of the architectural and structural type of the vessel

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

1. Purpose - dry cargo ship

2. Vessel class - O

3. The vessel's carrying capacity is 2000 tons.

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

Analysis of modern design and operation experience cargo ships domestic 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 hull capacity.

However, the aft location of the MO and superstructure from a purely shipbuilding point of view also has significant disadvantages. So, when running empty, the ship has a significant trim to the stern.

The aft location of the wheelhouse impairs the navigator's visibility along the ship's course, especially when sailing unladen with trim, when transporting a significant amount of cargo on deck (for example, stacks of timber), and when sailing together with a pushed non-self-propelled section. The location of residential and service premises in the aft superstructure located above the MO, i.e. in the noisiest area of ​​the ship, requires special, sometimes very expensive, design measures to reduce noise and vibration to the required level.

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

Motor ship of the Sixth Five-Year Plan type (project 576) is a medium-sized dry cargo ship 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 closures of the holds. Externally, Project 576 ships are distinguished by a higher bow and wide superstructure windows. Late-built ships 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. Prototype vessel class - "O"

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

3. Loaded displacement (Dgr) - 2740t.

4. The speed of the prototype vessel is 17.5 km/h.

5. Vessel length according to waterline (Lm) - 90m.

6. The width of the vessel along the vertical line (B) is 13 m.

7. Side height (H) - 4.8 m.

8. Load draft (Tgr) - 2.8 m.

9. Crew number (nek) - 27 people.

10. Volumetric displacement completeness coefficient - 0.836t/m3.

11. Hull weight meter - 0.105t/m3.

12. Cubic module LBH - 5620m3.

13. Mechanism mass meter (p) (p=Pm/N) -- 0.099KW.

Рм - mass of mechanisms

N is the total power of the main engines.

14. Admiralty coefficient (Ca) - 1300KW.

15. Relative length (LB) - 6.92

16. Relative draft (HT gr) - 1.71
