LIQUEFIED GAS CARRIERS

Why we use LIQUEFIED state?

Gas cargoes are carried in liquefied state.

Because the liquid occupies up to 850 times less

volume.

How can we LIQUIFIED the gas?

• Increasing the Pressure

• Reducing the Temperature

Type of Liquefied Gases?

• LPG - Liquefied Petroleum Gas• LNG - Liquefied Natural Gas• LEG - Liquefied Ethylene Gas• NH3 - Ammonia• Cl2 - Chlorine• Chemical gases

Etc………

Type of Gas Carriers

• Fully Pressurized Ships

• Semi-Refrigerated/Semi-Pressurized Ships
