How it applies
The IGF Code is mandatory under SOLAS for ships that use gases or other low-flashpoint fuels, such as LNG: generally new ships built on or after 1 January 2017, and existing ships converted to use these fuels. It doesn't apply to gas carriers covered by the IGC Code.
Who uses it
Owners and designers of LNG-fuelled ships, shipyards, engine and fuel-system makers, classification societies and crews on gas-fuelled vessels.
