Description

The invention relates to water vehicles and can be used in the design and construction of river and navy vessels for the transportation and pumping of flammable, flammable liquids, such as oil and oil products.

A boat is known - a barcon, formed from the first syllables “barge” and “container” (see RU No. 2149122, IPC VV 35/28, published on 05/20/2000), the sides and bottom of which are made with double walls, between which are placed pipelines and heat conductors with the ability to connect to the refrigeration and thermal installations of the vessel, providing the possibility of freezing it to the hold of the vessel, and heat-insulating materials that protect the cargo from low temperatures.

The disadvantages of the known analogue are the design complexity, the presence of a large number of loading and unloading mechanisms and devices, the high complexity of the technological operations of securing the cargo.

Also known is a bulk vessel (see EP 0722882 A1 of 07.24.1996), having a fuel tank for driving an engine adjacent to one hull, divided into two compartments by a bulkhead.

The disadvantage of this analogue is that such a design for the fuel tank does not exclude the possibility of fuel leakage if the hull of the vessel is damaged.

The closest in technical essence and technical result achieved - the prototype is a bulk barge (see Internet http://www.derrick.ru/?f=n&id=18893 project P6001) with a second bottom and second sides, in the area of cargo tanks. The hull is divided by transverse bulkheads, a longitudinal bulkhead is installed in the diametrical plane.

The disadvantages of the known prototype is the low operational reliability of the vessel, since loading and unloading of only one type of fuel is carried out by third-party means due to the lack of cargo pumps and a power source, in addition, the longitudinal bulkhead is not structurally protected from water penetration during a storm and fire from lightning during thunderstorm or other unforeseen fires, which may lead to a violation of the ecological and fire safety of the environment.

The technical task of the invention is to remedy these shortcomings, increase autonomy and reliability, ensure environmental safety of a bulk vessel, the technical result of which will be an increase in cargo capacity, the ability to load, transport, unload several types of oil products at the same time: oil, gasoline, kerosene, diesel fuel, oils, fuel oil , reduction of losses of transported oil products due to reduction in the process of loading and unloading of intermediate operations.

The specified technical result is achieved due to the fact that the bulk vessel containing the hull, including the deck, bottom and sides at a distance from the bow to the stern cofferdam is divided by transverse bulkheads, the second bottom and inner sides into two rows symmetrically located on both sides of the longitudinal bulkhead in two rows cargo tank compartments, under which between the bottom of the hull and the second bottom there are ballast compartments separated by waterproof transverse bulkheads, between the sides and the inside sides it also has ballast compartments, characterized in that the longitudinal bulkhead located along the entire length, from the bow to the stern of the hull, is waterproof and fireproof, and behind the stern cofferdam in the ship’s hull there is a diesel generator unit in the engine room and three cargo pumps in the pump room.

The longitudinal bulkhead is made waterproof and fireproof in the diametrical plane, located along the entire length of the hull from the bow to the stern to ensure the stability of the bulk vessel.

To ensure the stability of the bulk vessel, the ballast compartments separated by waterproof transverse bulkheads are made in height from 800 to 1000 mm from the hull bottom to the second bottom, and from 700 to 900 mm from the hull to the inside.

To increase the cargo capacity of cargo tanks, the deck above the cargo tanks is raised to a height of B = 400 ÷ 500 mm, and the second bottom has a slope of α = 2 ÷ 3 ° to the diametrical plane, which allows to increase the loading of oil products by 10 ÷ 15%.

A longitudinal waterproof firetight bulkhead in the diametrical plane is located along the entire length of the hull so that, if possible, if a fire occurs, it does not spread to the other side with cargo tanks.

The use of a diesel generator unit and cargo pumps for pumping directly from a bulk vessel will allow the simultaneous delivery of various oil products, such as oil, gasoline, kerosene, diesel fuel, oil, fuel oil, as well as reduce losses by eliminating additional unloading operations, for example, to another ship bypassing coastal terminals.

To fill the fluid, the ballast compartments are connected by a piping system.

During the transportation of goods, stability is ensured by the even distribution of goods in cargo tanks, and environmental safety by separation from the sides at the required distance with the second sides, from the bottom - the second bottom.

The arrangement of cargo tanks is symmetrical in two rows on both sides of the diametrical plane, the presence of liquid ballast in the ballast compartments increases the stability of a non-self-propelled bulk vessel, if cargo tanks were installed in one row, then when the vessel is rocking, changes in the landing of the vessel are possible, and accordingly, sharp fluctuations liquid level in cargo tanks.

In addition, ballast evens the landing of a self-propelled bulk vessel during handling operations.

Since the ballast compartments are completely sealed, the supply and pumping of liquid ballast into them is carried out through a piping system (not shown in the drawing).

The invention is illustrated by drawings:

Fig. 1 - general view;

Fig. 2 - top view;

Fig. 3 - top view of the machine and pump room;

Fig. 4 - section along aa;

Fig. 5 is a section along BB.

The bulk vessel is made in the form of a hull 1 (Fig. 1), containing deck 2, deck 3, raised to a height of 400 ÷ 500 mm, bottom 4, sides 5, waterproof transverse bulkheads 6, second bottom 7, with a slope α = 2-3 ° to the diametrical plane, inner sides 8 (Fig. 2), at a distance from the bow to the stern cofferdam 9 are located symmetrically on both sides of the diametrical plane cargo tanks 10, behind the aft cofferdam 9 there is a machine room 11 (Fig. 3), a pump room 12.

In the engine room 11, a diesel generator unit 13 is installed (Fig. 4), and in the pump room 12 three cargo pumps 14, two cargo pumps for diesel fuel (one main, the second reserve one) and one cargo pump for oil or other oil products.

The longitudinal bulkhead 15 (Fig. 5) is waterproof and fireproof, installed along the entire length, from bow to stern, hull 1, inner sides 8 and second bottom 7 with sides 5 and bottom 4 of body 1 with waterproof transverse bulkheads 6 form ballast compartments 16 moreover, the ballast compartments 16 are made in height from 800 to 1000 mm from the bottom 4 to the second bottom 7, and 700 to 900 mm from the side 5 to the inside side.

Works bulk vessel as follows.

Before loading from the ballast compartments 16 by a piping system, ballast - liquid is removed. Then, the cargo tanks 10 are loaded with oil or oil products from the tank farm.

When transporting a petroleum product in bulk, the arrangement of cargo tanks 10 increases stability, prevents the possibility of collision with other obstacles and an emergency in the event of oncoming high bow and side waves.

Unloading is carried out by three cargo pumps 14 installed in the pump room 12 and powered by a diesel generator unit 13 directly to the customer, especially in the northern and arctic conditions from a bulk vessel to surface and submarine vessels, tankers, while various oil products are simultaneously unloaded.

After unloading the cargo tanks 10, ballast - liquid is again pumped into the ballast compartments 16 by a piping system, which ensures alignment of the landing of the bulk vessel without bank and trim.

Using the proposed invention will significantly reduce losses and increase the cargo capacity of petroleum products, there is no need for intermediate loading and unloading terminals, the threat of violating the environmental safety of the environment.
