As shown in Fig.

Hereinafter, a gas bunker system 1 according to an embodiment of the present invention will be described with reference to Figs. 1 and 2. Fig.

A liquefied gas storage tank (10) stores liquefied gas to be supplied to the propulsion engine (50). The liquefied gas storage tank 10 must store the liquefied gas in a liquid state, at which time the liquefied gas storage tank 10 may have the form of a pressure tank.

Here, the liquefied gas storage tank 10 is not limited to various types.

The bunkering station 20 is connected to the liquefied gas storage tank 10 via a gas bunkering supply line 31 and a gas bunker recovery line 32 and is connected to a bunker vessel (e.g., LNG FPSO; not shown) (Not shown) for supplying fuel such as a customer, etc. to the liquefied gas storage tank 10 by a bunkering operation. Here, the bunker station 20 may form a separate space, may be formed to surround the space by a separate casing (not shown), and may be provided with an upper deck of a ship (not shown) Or may be installed on both side portions (not shown) of the ship.

The bunkering station 20 may be used to control the operation of the bunker station 20 by using inert fluid sprays (not shown), a drip tray (not shown), a davit crane (not shown), a connection joint And a variety of bunker equipment such as a system (not shown).

An inert fluid spray is a structure that protects the hull bulkhead by spraying an inert fluid such as water or nitrogen to the hull bulkhead (not shown). For example, when the fuel leaks during the bunkering operation and the cryogenic fuel reaches the hull bulkhead Moving may damage the hull bulkhead and cause safety accidents. However, the hull bulkhead can be protected by forming a curtain shape by ejecting fluid from the inert fluid spray to the hull bulkhead.

The drip tray is a structure for preventing damage to a ship (not shown). The drip tray is provided with a water tank (not shown in the drawing) (Fuel), and can be provided at a predicted point where the water falls as the gas bunker supply line 31 or the lower part to which the gas bunker recovery line 32 is connected.

The crane may lift the configuration of the bunting means to the bunkering station 20 so that the vessel may be bunkered and connected to bunkering means and the connection joint may be a configuration that connects the bunkering means and the liquefied gas storage tank 10 The fire monitoring system may be a fire detection monitor, a heat detection sensor, or the like.

Here, the detailed configuration of the crane, the connection joint and the fire monitoring system is omitted in the known configuration.

The gas bunker supply line 31 connects the liquefied gas storage tank 10 and the bunkering station 20 and can supply liquefied gas from the bunkering station 20 connected to the bunker means to the liquefied gas storage tank 10 .

The specific configuration of the gas bunker supply line 31 will be described in detail with reference to FIG.

3 is an enlarged view of part A of the gas bunker line according to the invention.

As shown in FIG. 3, the gas bunker supply line 31 may include a heat insulating portion 311, an outer tube 312, and an inner tube 313.

The heat insulating portion 311 may be formed at the outermost portion of the gas bunkering supply line 31 to cover the outer tube 312 and surround the outer tube 312 to be described later. At this time, the heat insulating portion 311 may be formed with a communication portion (not shown) so that the liquid nitrogen first circulation line 431 or the liquid nitrogen second circulation line 432, which will be described later, can be connected to the inlet or outlet .

The heat insulating portion 311 insulates the heat source penetrating from the outside of the gas bunkering supply line 31 to the inside and can prevent the temperature of the liquefied gas or the refrigerant (for example, the liquid nitrogen LN2) from rising . The heat insulating portion 311 may be made of, for example, EPS, PU, glass wool, or the like, and is not limited to the above-exemplified materials.

The outer tube 312 is formed between an inner tube 313 and a heat insulating portion 311 to be described later and flows through the inner tube 313 by cooling the inner tube 313 by flowing the coolant, Can be supplied. The outer tube 312 may be in the form of a pipe.

The outer tube 312 may be formed of stainless steel, and may be formed to surround the inner tube at a predetermined distance, so that a space through which the refrigerant can flow may be formed.

The outer tube 312 may include an inlet (not shown) through which the refrigerant flows into one side and an outlet (not shown) through which the refrigerant flows out to the outside. The inlet and the outlet may be formed of a liquid nitrogen first And is connected to the circulation line 431 to allow the refrigerant to flow in or out. The inlet may be formed on the outer tube 312 at a position close to the bunkering station 20 side and the outlet may be formed on the outer tube 312 at a position close to the liquefied gas storage tank 10 side, But is not limited thereto.

The inner pipe 313 is formed to be surrounded by the outer pipe 312 and the liquefied gas can flow to supply the liquefied gas from the bunkering station 20 to the liquefied gas storage tank 10. Here, the inner pipe 313 may be formed of stainless steel in the form of a pipe.

The gas bunkering supply line 31 is constituted by the heat insulating portion 311, the outer pipe 312 and the inner pipe 313 in such a manner that while the liquefied gas is supplied to the liquefied gas storage tank 10 during bunkering, And it is possible to prevent the liquefied gas from being phase-changed into the evaporation gas by continuous supply of cold heat.

In addition, the gas bunkering supply line 31 can cool down by receiving the refrigerant in advance to the outer pipe 312 before the bunkering, and can thereby shut off the evaporation gas generated on the supply line during bunkering .

The gas bunkering recovery line 32 connects the bunkering station 20 and the liquefied gas storage tank 10 and can supply the vaporized gas generated in the liquefied gas storage tank 10 to the bunkering station 20. Here, the gas bunkering recovery line 32 may also be formed with a heat insulating material, an outer pipe, and an inner pipe, such as the gas bunkering supply line 31, and this configuration is the same as that of the gas bunkering supply line 31 described above Let's replace it.

When the evaporation gas is generated in the liquefied gas storage tank 10, the gas bunkering recovery line 32 allows the evaporation gas to flow to the bunkering station 20 to supply cold heat from the refrigerant flowing to the outer pipe, . The gas bunker recovery line 32 may be connected to the gas bunker supply line 31 at the bunkering station 20 and may re-supply the re-liquefied vapor gas back to the liquefied gas storage tank 10.

Accordingly, the gas bunkering system 1 of the present invention can effectively treat the evaporative gas generated in the liquefied gas storage tank 10 through the gas bunkering recovery line 32, so that the evaporation gas processing apparatus can be built in the bunkering means And there is no need to provide a means for treating the evaporative gas (evaporative gas compressor or the like) in the ship itself, thereby securing the space of the ship and drastically reducing the system construction cost.

In the embodiment of the present invention, the liquid nitrogen first circulation line 431 and the liquid nitrogen second circulation line 432 may be further included, and each of the circulation lines 431 and 432 may have a separate valve (not shown) So that the flow rate of the refrigerant flowing into the outer pipe 311 can be controlled through the adjustment of the degree of opening.

The liquid nitrogen first circulation line 431 may be connected to the inlet and outlet of the gas bunker supply line 31 and may include a liquid nitrogen storage tank 41 and a liquid nitrogen purifier 42 .

The liquid nitrogen second circulation line 432 may be connected to the inlet and outlet of the gas bunker recovery line 32 and may also include a liquid nitrogen storage tank 41 and a liquid nitrogen purifier 42.

The liquid nitrogen storage tank 41 may store the refrigerant to flow to the outer pipe 311, and may be formed as a pressurized container due to the characteristics of a refrigerant having a vaporization point of a very low temperature.

The liquid nitrogen storage tank 41 is provided on the liquid nitrogen first and second circulation lines 431 and 432 to supply the liquid refrigerant to the outer pipe 312 of the gas bunker supply line 31, The liquid nitrogen storage tank 41 can receive the re-liquefied refrigerant from a liquid nitrogen re-liquefier (not shown) provided upstream of the first and second liquid nitrogen lines 431 and 432.

Here, the liquid nitrogen remover liquefies the vaporized refrigerant to the liquid nitrogen storage tank 41 by transferring cold heat to the inner pipe 313 or the liquefied gas flowing into the inner pipe 313, So that the refrigerant can be supplied again to the refrigerant circuit 312 so that the refrigerant can circulate.

The liquid nitrogen purifier 42 removes the liquefied gas mixed with the refrigerant when the liquefied gas leaks into the outer pipe 312 and supplies only the pure refrigerant to the liquid nitrogen storage tank 41.

The liquid nitrogen purifying section 42 purifies the liquefied gas-refrigerant mixed fluid into pure refrigerant when the liquefied gas leaks into the outer pipe 312 during bunkering due to breakage of the inner pipe 313, thereby removing the explosive liquefied gas So that the safety of the gas bunkering system 1 can be improved and the reliability of the bunkering operation can be improved.

The propulsion engine 50 consumes liquefied gas or evaporation gas supplied from the liquefied gas storage tank 10 to generate power, and may be, for example, an ME-GI engine.

As the piston (not shown) in the cylinder (not shown) reciprocates by the combustion of the liquefied gas or the evaporative gas, the propulsion engine 50 rotates the crankshaft (not shown) connected to the piston, A shaft (not shown) connected to the shaft can be rotated. Therefore, as the propeller (not shown) connected to the shaft finally rotates when the propulsion engine 50 is driven, the hull is moved forward or backward.

As described above, the gas bunkering lines 31 and 32 according to the present invention and the gas bunkering system 1 including the same can minimize the generation of evaporative gas generated in the bunkering, and the internal pressure of the liquefied gas storage tank 10 So that it is possible to reduce the construction cost of the system even if there is no need to construct a separate device for treating the evaporative gas generated in bunkering.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the same is by way of illustration and example only and is not to be construed as limiting the present invention. It is obvious that the modification and the modification are possible.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
