C. How is LNG shipped?

Specially designed ships are used to transport LNG to U.S. import terminals. The ships can carry LNG over long distances and are constructed of specialized materials and equipped with systems designed to safely store LNG at temperatures of -260 °F (-162.2°C)
All LNG ships are constructed with double hulls. This construction method increases the integrity of the hull system, provides insulation for the LNG and provides protection for the cargo tanks in case of an accident
Three basic tank designs have been developed for LNG ship containment and transport: prismatic free-standing, spherical, membrane
The "International Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk" (Gas Tanker Code) and Coast Guard regulations require that LNG ships meet a Type IIG standard of subdivision, damage stability, and cargo tank location
LNG is also transported via truck. LNG tanker trucks typically carry between 10,000 and 12,000 gallons (38-to-45 m³) of LNG. LNG trucks are used to deliver LNG from its source to remote or satellite peak sharing facilities. LNG trucks are also used with portable vaporizers as a temporary supply of natural gas if normal supplies are interrupted or for peak sharing during abnormal winter conditions
