Abstract

PURPOSE:To markedly increase the loaded cargoes and improve the navigation faculty by forming a cargo deck extending upward over a mooring deck in the bow part frmo a rear hold division and forming a plurality of holds divided by the outer plates extending upwardly from the cargo deck, onto the mooring deck. CONSTITUTION:As for a carriage vessel exclusively used for cars, a plurality of cargo decks 13 are extended towards a bot 02 from a rear hold division, in the upper part of a mooring deck 04 in the opened state in the conventional, and a plurality layers of bow upper part holds 14 are formed by covering the front side part of the cargo deck 13 by the outer plates 1, and the uppermost part is formed into an upper deck 15, and a mooring rope 9 is introduced outside the vessel from the opened port 10 formed on the outer plate 11 of the edge part 12 of the mooring deck 04. Therefore, the wind pressure resistance in the bow part 02 is reduced by the covering with the outer plate 11, and the propulsion faculty is improved, and the hold area with the restricted hull dimension is increased, and the loaded cargoes ca be increased, and navigation efficiency can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a ship equipped with an upper bow hold suitable for a car carrier, a livestock carrier, a multi-purpose cargo ship, etc., which require a multi-layered ship deck.

[Conventional technology]

The bow of a conventional ship is usually provided with a mooring deck equipped with an anchor lifting machine or a mooring device, and is not provided with a hold for loading cargo.

In other words, with the exception of the bow water tank, anchor chain floor, etc. located below the mooring deck, there was no idea of loading cargo on or above the mooring deck. Figures 3 and 4 are part 1
As an example, it shows a side view and a perspective view of a car carrier used for transporting car products. As shown in the figure, a mooring deck 04 equipped with a mooring device 03 is provided at the bow 02 of the hull 01, and a cargo deck 05 for loading automobiles is provided behind the bow bulkhead 06. There is. The cargo deck 05 is shielded from the outside by an outer panel that continuously extends upward from the hull outer panel and an upper cargo deck 05 or an upper deck 08, thereby forming a hold section 07. Of course, the hold section 07 is reinforced with bulkheads, columns, etc. for reasons such as strength. However, the bow section is not provided with any section for loading cargo, etc., except for an anchor chain floor (not shown) provided below the mooring deck 04 or a bow water tank 08 for trim adjustment.

[Problem that the invention seeks to solve]

By the way, in a conventional ship, as shown in FIG. 4, the bow bulkhead 06 stands up behind the cargo deck 04, so the wind pressure resistance caused by this is large and the propulsion performance is likely to be impaired.

In today's world, attention is being focused on energy conservation, and measures are being taken to reduce fuel consumption in propulsion engines, etc., and it has become essential to improve propulsion performance by improving the hull shape.

Furthermore, as shown in Figures 3 and 4, from the perspective of loading cargo, the entire bow section where the mooring deck 04 is installed is a dead space. In order to increase the number of loaded vehicles, the vertical distance between the cargo decks 05 is reduced, and the cargo decks 05 are installed upwards to increase the area of the cargo decks 05 (to improve operational efficiency).

However, reducing the vertical distance between the cargo decks 05 has a limit due to the height of the cargo or the workability of the workers handling the cargo, and increasing the height of the cargo decks 05 upwards is important for the stability of the ship. The reality is that the number of vehicles loaded cannot be increased as expected due to the above problems.

Of course, ships may be made larger in order to increase cargo capacity and improve operational efficiency.

The present invention has been made in view of the problems that the propulsion performance of conventional vessels is hindered and the number of loaded vessels cannot be increased. It is an object of the present invention to provide a ship equipped with a bow upper hold capable of reducing wind pressure resistance and increasing the amount of cargo carried by covering the sides with outer plates.

[Failure to solve the problem]

Therefore, a ship equipped with the bow upper hold of the present invention has a multi-layered hold partitioned by a cargo deck extending from the aft cargo compartment above the mooring deck at the bow, and a shell plate extending upward from the cargo deck. It is characterized by the fact that it is formed above the mooring deck.

[Effect]

According to the above-mentioned ship equipped with the bow upper hold of the present invention, the outer plate of the hold section provided at the upper part of the bow can be formed into a curved shape with low wind pressure resistance, so that the resistance to wind from the bow direction is reduced. Additionally, the previously unused space above the bow mooring deck can be utilized as a hold area for loading cargo.

[Embodiment] Hereinafter, a ship equipped with an upper bow hold will be described as an embodiment of the present invention with reference to the drawings. Fig. 1 is a side view showing the case where the ship of the present invention is applied to a car carrier, and Fig. 2 is a perspective view of FIG. 1;

In the figure, 01 is the hull, 02 is the bow part of the hull 01, and 04 is the mooring deck installed on the bow part 02. The mooring winch 03 shown in Figure 4 is installed, and the mooring winch 03 etc. shown in Figure 4 is installed, and the mooring winch 03, etc. Through the opening 10, the mooring line 9 is guided outboard in the same manner as before. Reference numeral 11 denotes an outer plate that extends almost vertically upward from the edge 12 of the mooring deck 04, and has a curved surface shape along the edge 12. Numeral 13 is a multi-layer cargo deck extending from the cargo deck 05 of the aft cargo compartment 07 to above the mooring deck 04, and its periphery is the uppermost part of the aft upper deck 08 of the outer panel 11 and the cargo deck 13. The hold compartment 14 is surrounded by an upper deck 15 extending from the upper deck 15 .

In the above embodiment, the outer plate 11 is connected to the edge 12 of the mooring deck 04.
Although the present invention is not limited to such an example, the present invention is not limited to such a structure. The bow end may be narrowed to have a streamlined shape with low air resistance, or it may be tilted toward the rear of the hull and toward the hull centerline instead of vertically upward.In this case, the hull resistance However, there is a problem in that the capacity of the hold above the newly installed mooring deck 04 is reduced.

Further, the opening 10 may also be configured such that no outer plate 11 is provided between the mooring deck 04 and the newly installed cargo deck 13 just above the mooring deck 04 to ensure visibility.

〔Effect of the invention〕

As described above, according to the ship equipped with the bow upper hold of the present invention, a multi-layered cargo deck is installed above the mooring deck, which has conventionally been in an open state, extending from the rear hold section toward the bow.
By covering the front side of the extended cargo deck with outer plating, wind pressure resistance at the bow is reduced, improving propulsion performance and increasing the area of the cargo hold within the limited hull dimensions. This system has the advantage of increasing the operational efficiency of ships, since it can greatly increase the amount of cargo on board, making it extremely useful for industry.
