Definitions
- the present invention relates to a liquefied gas storage tank capable of storing liquefied gas, such as LNG and LPG, and more particularly, to suppress the sloshing phenomenon and to support the load of the upper structure.
- the present invention relates to a liquefied gas storage tank disposed in a row and an offshore structure having the storage tank.
- Natural gas is transported in a gaseous state through onshore or offshore gas piping, or transported to a remote consumer while stored in a carrier in the form of liquefied gas (such as LNG or LPG).
- Liquefied gas is obtained by cooling natural gas to cryogenic temperature (approximately -163 °C), and its volume is reduced to about 1/600 than that of natural gas in gas state, so it is very suitable for long distance transportation by sea.
- LNG carriers for loading LNG to drive the sea and unloading LNG to land requirements include a liquefied gas storage tank capable of withstanding the cryogenic temperature of liquefied gas.
- Liquefied gas storage tanks installed inside LNG carriers can be classified into independent type and membrane type, depending on whether the load directly affects the insulation.
- Independent tank type storage tanks are either SPB type or Moss type storage tanks. These types of storage tanks use a large amount of non-ferrous metal as the main material, which greatly increases the manufacturing cost of the storage tanks.

- the Mark III type storage tank includes a primary sealing wall made of a 1.2 mm thick stainless steel membrane, a secondary sealing wall made of a triplex, a polyurethane foam, and the like.
- the primary heat insulating wall and the secondary heat insulating wall formed are laminated on the inner surface of the hull.
- the sealing wall has corrugated wrinkles, and shrinkage by the cryogenic LNG is absorbed by the corrugated wrinkles so that a large stress is not generated in the membrane.
- Mark III type insulation system is not easy to reinforce due to its internal structure, and its ability to prevent LNG leakage is weaker than that of GTT NO 96 type secondary sealing wall due to the characteristics of secondary sealing wall.

- the width of the storage tank is reduced by more than half, the movement intrinsic period of the liquid cargo, that is, LNG, becomes far from the intrinsic period of the offshore structure, thereby reducing the magnitude of the movement of the liquid cargo.
- the floating structure such as LNG FPSO is required for a storage tank that can withstand such a heavy load because the weight of the upper structure is increased, in the case of a storage tank 110 of a two-row arrangement structure such as the present invention as a thin partition

Therefore, the inner wall surface of the hull 101 and the cofferdam partition walls 106 and 108 should be made of low temperature steel that is resistant to low temperatures.
- the cofferdam particularly the longitudinal cofferdam 107, located between the storage tanks 110, is a closed space, so that heat is not supplied from the outside so that the internal temperature may drop to about -60 ° C.
