3. LNG Ships and Routes LNG - Liquefied Natural Gas

4. Cooled to approximately -160°C (-260°F)

5. LNG ~ 1/600 volume of Natural Gas, making it practical to transport by shipHull FormsDouble Hull

6. Majority of new ships under construction are 120,000 m³ to 140,000 m³.

7. Orders for ships with capacity up to 260,000 m³.

8. Approximately 300 ships are engaged in deep sea movement of LNG.Propulsion Systems3 Main TypesSlow Speed DieselTwin Screw – Fuelled by Heavy Fuel OilMedium Speed Dual-Fuel DieselSingle/Twin Screw with diesel/electric drive fuelled by Marine Diesel Oil with boil off or Heavy Fuel OilGas TurbinesMainly Twin Screw fuelled by Marine Gas Oil or Gas Fuel

9. Propeller and RudderIncreased Propulsive Efficiency 4-6%

10. Simple and Robust

11. Easily retrofitted to existing vessels
