Liquefied natural gas (LNG) is natural gas cooled to -161°C to form a liquid. Cooling natural gas to a liquid reduces the volume of natural gas so that it can be transported safely and efficiently by ship where it is converted back to a gaseous state for use.

LNG shipping has a proven safety record. The world’s first LNG tanker shipped LNG safely from Louisiana to the United Kingdom in 1959. With 50-plus years of marine shipping experience, more than 135,000 LNG carrier voyages have taken place around the world without major accidents, safety problems, or security issues, either in port or at sea.

LNG carriers are designed to have a high degree of safety.  This is accomplished by:

  • Using double hulled vessels
  • Separating LNG cargo tanks from the hull structure using thick insulation
  • Installing closed cargo systems for loading or discharging, to prevent the venting of vapours
  • Temperature and pressure monitoring
  • Gas detection and cargo tank liquid level indicators
