Figure 1 shows a vehicle carrier 1 according to an embodiment of the present invention.

Referring to FIG. 1, the vehicle carrier 1 includes a fuel storage tank 10, an engine room 20, an engine casing 21, a ballast tank 30, lamps 50, 51, and a cabin 60. Includes.

The vehicle carrier 1 has a plurality of decks on which vehicles are loaded. A plurality of decks may be arranged between the cabin 60 provided at the top of the vehicle carrier 1 from the bottom of the hull of the vehicle carrier 1. Vehicles can be moved, parked, and loaded on the deck, and can be moved between decks through a ramp 40, which will be described later. For example, the plurality of decks may be composed of decks 1 to 12 or decks 1 to 9 in order from the bottom, and a fuel storage tank 10, to be described later, is provided on deck 1, and an entry/exit tank 10 to be described later is provided on deck 1. Deck D may be provided on deck 5.

The plurality of decks may have the same height, but are not limited thereto. For example, based on the access deck (D), which will be described later, the access deck (D) and the deck provided above the access deck (D) have a relatively greater height compared to the deck provided below the access deck (D). You can have it.

The vehicle carrier 1 may include ramps 50 and 51 for entry and exit of vehicles. Depending on the position, the lamp may include a rear lamp 50 provided at the stern of the carrier ship 1, a side lamp 51 provided on one side of the carrier ship 1, etc., but the location and number of lamps is not limited. The ramps 50 and 51 are folded during navigation, and can be unfolded when docked and connected to the port to provide a path for vehicles to enter and exit. Vehicles can enter and exit the entrance deck (D) of the carrier vessel (1) through ramps (50, 51).

The entrance deck (D) is the deck where vehicles first enter the vehicle carrier (1), and may be provided with a ramp 40 that connects to decks on other floors. Since the access deck (D) is where vehicles move the most among the plurality of decks, the loading and unloading efficiency of the carrier ship (1) depends on whether structures other than the ramp 40 exist on the vehicle access deck (D). can be decided.

The vehicle carrier 1 may include a fuel storage tank 10, an engine room 20, and a ballast tank 30 below the access deck (D).

The fuel storage tank 10 may be a gas fuel storage tank that stores gas fuel for use as fuel at the destination of the carrier ship 1. Specifically, the fuel storage tank 10 may be a high-pressure pressure vessel capable of storing liquefied gas at extremely low temperature. When the fuel storage tank 10 is a high-pressure pressure vessel, if it is provided as a single vessel, the loading capacity of liquefied gas is small, making long-distance navigation difficult. The carrier 1 according to this embodiment is equipped with a plurality of high-pressure pressure vessels as a fuel storage tank 10 and has a structure suitable for long-distance transportation of vehicles. Preferably, the carrier vessel 1 may be equipped with two high-pressure pressure vessels as fuel storage tanks 10.

The high-pressure pressure vessel may have a cylindrical shape to withstand the pressure of the liquefied gas stored therein, and its longitudinal direction may be arranged parallel to the longitudinal direction of the carrier (1). A cylindrical container can maximize the radius of the tank compared to a bilobe-shaped container, thereby increasing the amount of fuel that can be stored.

When the carrier ship 1 is equipped with a plurality of high-pressure pressure vessels, the plurality of high-pressure pressure vessels may be arranged in parallel with each other. Hereinafter, the fact that a plurality of high-pressure pressure vessels are arranged in parallel means that only one high-pressure pressure vessel is arranged in the space between the entrance deck (D) and the bottom of the ship based on the height direction of the carrier ship (1). That is, in the carrier ship 1 according to this embodiment, a plurality of high-pressure pressure vessels may be arranged side by side rather than stacked in the height direction. By arranging the high-pressure pressure vessels one by one in parallel between the access deck (D) and the bottom of the ship, it is possible to easily secure ramp placement space for vehicle movement compared to the case where the high-pressure pressure vessels are stacked.

A pump (not shown) may be provided in the fuel storage tank 10, and the liquefied gas stored in the fuel storage tank 10 may be extracted through the pump. The pump may be installed inside or outside the fuel storage tank 10, and when placed inside the fuel storage tank 10, it may be installed to be submerged in liquefied gas. The liquefied gas drawn out by the pump may be supplied to the fuel gas processing unit 42 through the dome structure 11, which will be described later.

The vehicle carrier 1 may include an engine room 20 in which an engine for propelling the carrier 1 is disposed at the stern. The engine can be operated using the liquefied gas stored in the fuel storage tank 10 as fuel as described above. As shown in FIG. 1, if the engine room 20 is placed adjacent to the fuel storage tank 10, the length of the pipe for supplying fuel can be shortened, thereby securing space and cost advantages. The engine room 20 may further include a power generation engine, but is not limited thereto. Exhaust gas generated within the engine room 20 may communicate with the engine casing 21. The engine casing 21 may further include a stack (not shown) to discharge exhaust gas to the outside of the carrier 1.

The vehicle carrier 1 may include one or more ballast tanks 30 at the bottom. The ballast tank 30 can maintain the seaworthiness and resilience of the carrier ship 1 by injecting or discharging fresh water, sea water, etc. depending on the vehicle loading status and operating conditions of the carrier ship 1. The carrier ship 1 according to this embodiment includes a plurality of ballast tanks 30 disposed between the access deck D and the bottom of the ship. For example, the ballast tank 30 may include first to fifth ballast tanks 31 to 35, and may be arranged from the bow to the stern in order, starting from the first ballast tank 31. At least one of the plurality of ballast tanks 30 may be disposed below the fuel storage tank 10. For example, the fourth ballast tank 34 and the fifth ballast tank 35 may be disposed below the fuel storage tank 10.

The vehicle carrier 1 may include a cabin 60 at the top. The carrier ship 1 may have a plurality of deck structures for maximum vehicle loading, and may provide a cabin 60 on the deck structure.
