LNG Supplies to the World


Globally, liquefied natural gas (LNG) has been transported and consumed for more than 40 years and has an incredibly strong safety record.

Chevron has an international reputation for the reliable and safe delivery of LNG to its customers in the Asia-Pacific region. More than 1,500 cargoes have been delivered on schedule to customers since the start of LNG exports in 1989.

The typical LNG carrier measures some 900 feet in length and about 140 feet in width.

A fleet of nine purpose-built LNG ships each have a capacity to carry 125,000 cubic metres of LNG. It takes seven to ten days to ship the cargo from Western Australia to customers in Japan, Korea, China and Taiwan.

LNG tankers run off the natural gas they transport. During a ship’s journey the LNG cargo warms very slightly, producing boil-off that is fed into the ship's propulsion plant and used as fuel.

Tankers are double-hulled and heavily insulated to prevent leakage or rupture. The LNG is stored in a special containment system within the inner hull where it is kept at a temperature of minus 162 degrees Celsius (-256°F) and is not pressurised. LNG is not flammable.

There are two main types of LNG ships – those that use the Moss Rosenberg spherical containment system, and those that use the more modern Membrane Containment System.

The typical carrier measures some 900 feet in length, about 140 feet in width and 36 feet in water draft and costs about AU$160 million.
