An LNG fueling station according to the present invention includes: an installation part on which an LNG tank container is installed, and a supply part for supplying liquefied natural gas from the LNG tank container installed on the installation part to an object for supply, wherein the LNG tank container can be transported and installed while storing the liquefied natural gas, and the LNG tank container is transported to the installation part and then installed on the installation part.

A set (10) for dispensing liquefied gas from a vessel (100) comprises a supporting structure (1), a pump (2) and a conditioning system (4). The supporting structure is designed for maintaining both the pump and the conditioning system inside the vessel when the set is in operation condition for dispensing a flow of liquefied gas. The set allows easy handling, simple fitting to the vessel and easy removal from the vessel because a main part of said set can be handled as a one-block element.

An apparatus and method of storing and transporting, in a dual-use cryogenic storage tank, a cryogenic liquid having a liquefaction temperature. A first pump empties the tank of a first portion of the cryogenic liquid, thereby leaving a second portion of the cryogenic liquid in the cryogenic storage tank. A second portion of the cryogenic liquid is focused at a location on a bottom of the cryogenic storage tank. Using a second pump located at the location, the cryogenic storage tank is emptied of the second portion of the cryogenic liquid, whereby a residual portion of the cryogenic liquid is left therein. Using a focused heating structure, heat may be delivered to the location to raise the temperature of the residual portion above the liquefaction temperature, thereby vaporizing all of the residual portion.

A ship comprising an engine is disclosed. The ship comprising an engine comprises: a self-heat exchanger which heat-exchanges boil-off gas discharged from a storage tank; a multi-stage compressor which compresses, in multi-stages, boil-off gas that passed through the self-heat exchanger after being discharged from the storage tank; a first decompressing device which expands one portion of boil-off gas that passed through the self-heat exchanger after being compressed by the multi-stage compressor; and a second decompressing device which expands the other portion of the boil-off gas that passed through the self-heat exchanger after being compressed by the multi-stage compressor, wherein the self-heat exchanger uses boil-off gas discharged from the storage tank and boil-off gas expanded by the first decompressing device as refrigerants for cooling boil-off gas compressed by the multi-stage compressor.
