A system for transferring a fluid includes a transfer line connecting a storage tank and an LNG carrier, a loading arm provided on the transfer line, an emergency shutoff device configured to shut off the transfer line, a bypass line connecting the transfer line and the storage tank, and a bypass valve provided in the bypass line. The storage tank includes a fluid reception pipe configured to receive the fluid from the outside and a BOG pipe configured to discharge a boil-off gas of the fluid generated in the storage tank to the outside, and the bypass line is connected to at least one of the fluid reception pipe or the BOG pipe.

A system and a method for liquefied fuel storage are provided. The system includes a first module including a first outer vessel wall and a cryotank, a second module including a second outer vessel wall and a submerged pump at partially inside the second outer vessel wall, and a third module including a third outer vessel wall. The first, the second, and the third outer vessel walls are connected to provide an enclosure as an outer vessel.

A doser for dispensing a cryogenic fluid includes a doser body configured to receive the cryogenic fluid. A dosing arm has a proximal end and a distal end, with a central passage extending between the proximal and distal ends and configured to receive cryogenic fluid from the doser body. Multiple dosing heads are mounted to the distal end of the dosing arm with each of the dosing heads including a dosing valve. The dosing heads are configured to receive cryogenic fluid from the central passage of the dosing arm and to dispense the cryogenic fluid when the dosing valve is opened.

A structure for an offshore plant has a plurality of module portions mounted on a structure body in which a storage tank for storing liquefied natural gas is installed. A pump opening serving as the inlet/outlet of a pump for pumping up the liquefied natural gas from the storage tank is formed in the structure body, and the pump opening is disposed between the module portions adjacent to each other.
