TLDR
In this article, a procedure for removing gas in a fuel gas tank without causing problems such as securing of an installation space and cost rise is presented, where a vessel (100) is provided with gas removal equipment (10) provided with a gas compression unit (20), a gas heater unit (30, a gas combustion unit (40), and an inert gas supply unit (50).Abstract:
PROBLEM TO BE SOLVED: To perform a procedure for removing gas in a fuel gas tank without causing problems such as securing of an installation space and cost rise.SOLUTION: By equipping a vessel (100) with gas removal equipment (10) provided with a gas compression unit (20), a gas heater unit (30), a gas combustion unit (40), and an inert gas supply unit (50), fuel gas in a tank (110) is removed even in the vessel (100) not provided with devices for performing a procedure for removing gas.read more

Process and apparatus for purging gas-containing storage tanks in vessels
TL;DR: In this article, a process and apparatus for purging gas storage tanks comprises generating a gas inert with respect to the stored gas, displacing the storage gas in the tank with part of the inert gas and admixing another part of inert gas with the removed from the tanks, whereby in the case of combustible stored gas explosive mixtures are avoided.
Patent
Fuel supply system for ship
TL;DR: In this paper, an independent tank for storing liquefied natural gas and having an internal pressure maintained at substantially the atmospheric pressure, a feeding tank 5 for temporarily storing the liquid natural gas delivered from the independent tank 4, and a gas compressor 8 which compresses boil off-gas introduced from the Independent tank 4 and which supplies the boil off gas to at least either of an internal combustion engine 2 and/or a gas combustion device 3 which are arranged on the downstream side.
