LNG fueling station and LNG fueling method using LNG tank container

1. A liquefied natural gas (LNG) fueling station, comprising:

an installation part comprising:

a base mounted on a ground in order to receive an LNG tank container; and

a first pair of linear grooves formed on the base, and a second pair of linear grooves formed on the ground, a direction along the first and second pairs of linear grooves oriented parallel to each other;

a supply part configured to supply liquefied natural gas from the LNG tank container received on the installation part to an object; and

a loading and unloading assembly configured to load or unload the LNG tank container from a transporting equipment by moving together with the LNG tank container between the installation part and the transporting equipment,

wherein the loading and unloading assembly comprises:

a movable part guided by the first pair of linear grooves to reciprocate linearly on the installation part in a first direction or a second direction between a front end and a rear end of the installation part, and

a support part guided by the second pair of linear grooves and connected to the movable part through a connection structure to move together with the movable part, wherein the support part engages the LNG tank container to provide support to the LNG tank container during the loading and the unloading of the LNG tank container,

wherein the loading and unloading assembly enables the LNG tank container to move in the first direction when the LNG tank container is unloaded from the transporting equipment and in the second direction when the LNG tank container is loaded to the transporting equipment, by moving together with the LNG tank container in the first direction or second direction, respectively, and

wherein the liquefied natural gas is supplied to the object at a consumer site after completing installing the LNG tank container on the installation part through the loading and unloading assembly and transferring the liquefied natural gas to the object at the consumer site through the supply part.

2. The LNG fueling station of claim 1 , wherein the movable part is movably provided in the installation part and is detachably fixed to the LNG tank container.

3. The LNG fueling station of claim 2 , wherein the movable part comprises:

a movable base movably installed on the installation part; and

a movable lifter configured to lift the LNG tank container, the movable lifter being provided on the movable base and detachably fixed to the LNG tank container.

4. The LNG fueling station of claim 2 , wherein the support part is detachably fixed to the LNG tank container, and configured to move together with the movable part at the outside of the installation part while supporting the LNG tank container.

5. The LNG fueling station of claim 4 , wherein the support part comprises:

a support base configured to move together with the movable part at the outside of the installation part; and

a support lifter configured to lift the LNG tank container, the support lifter being provided on the support base and detachably fixed to the LNG tank container.

6. The LNG fueling station of claim 4 , wherein:

the movable part is fixed to an end of one side of the LNG tank container to move the LNG tank container inside the installation part; and

the support part is fixed to an end of the other side of the LNG tank container to move the LNG tank container together with the movable part at the outside of the installation part.

7. The LNG fueling station of claim 1 , wherein the supply part comprises:

a main pipe connected to the LNG tank container;

a main valve provided in the main pipe and opening/closing the main pipe; and

a fueling part connected to the main pipe to fuel the liquefied natural gas to the object for supply.

8. The LNG fueling station of claim 7 , wherein the supply part further comprises:

a vaporizer configured to receive the liquefied natural gas from the LNG tank container and vaporize the liquefied natural gas to generate natural gas; and

a compressor configured to receive natural gas from the vaporizer and compress the natural gas to generate compressed natural gas (CNG).

9. A liquefied natural gas (LNG) fueling station, comprising:

an installation part comprising:

a base mounted on a ground in order to receive an LNG tank container; and

a first linear groove formed on the base, and a second linear groove mounted on a ground;

a supply part configured to supply liquefied natural gas from the LNG tank container received on the installation part to an object; and

a loading and unloading assembly configured to load or unload the LNG tank container from a transporting equipment by moving together with the LNG tank container between the installation part and the transporting equipment,

wherein the loading and unloading assembly comprises:

a movable part guided by the first linear groove formed on the base to reciprocate on the installation part in a first direction or a second direction between a front end and a rear end of the installation part;

a support part guided by the second linear groove connected to the movable part through a connection structure to move together with the movable part, wherein the support part engages the LNG tank container to provide support to the LNG tank container during the loading and the unloading of the LNG tank container; and

a motor part configured to move the movable part during the loading and the unloading of the LNG tank container,

wherein the loading and unloading assembly enables the LNG tank container to move in the first direction when the LNG tank container is unloaded from the transporting equipment and in the second direction when the LNG tank container is loaded to the transporting equipment, by moving together with the LNG tank container in the first direction or second direction, respectively, and

wherein the liquefied natural gas is supplied to the object at a consumer site after completing installing the LNG tank container on the installation part through the loading and unloading assembly and transferring the liquefied natural gas to the object at the consumer site through the supply part.

10. The LNG fueling station of claim 9 , wherein each of the first linear groove and the second linear groove is a pair of parallel groves.
