Answer
IGF Code deals with the safe use of gases or low-flashpoint fuels for propulsion and power generation, whereas IGC Code deals with ships carrying liquefied gases in bulk as cargo. In short, IGF is fuel safety and IGC is cargo safety.”
IGF Code and IGC Code are different in purpose and application.
| Point | IGF Code | IGC Code |
|---|---|---|
| Full name | International Code of Safety for Ships using Gases or other Low-flashpoint Fuels | International Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk |
| Main purpose | Safe use of gas/low-flashpoint fuel as ship fuel | Safe carriage of liquefied gases as cargo in bulk |
| Typical ships | LNG/LPG/methanol-fuelled ships that are not necessarily gas carriers | LNG carriers, LPG carriers, ethylene carriers, etc. |
| Main focus | Fuel tanks, bunkering, fuel supply, ventilation, gas detection, ESD, machinery-space safety | Cargo containment, cargo tanks, reliquefaction, cargo piping, cargo machinery, toxic/flammable cargo hazards |
| SOLAS link | Mainly SOLAS Chapter II-1, Part G | Mainly SOLAS Chapter VII |
| Certificate | Compliance forms part of relevant SOLAS statutory certification | International Certificate of Fitness for the Carriage of Liquefied Gases in Bulk |
| Cargo use as fuel | Normally not the main scope | Gas carriers may use cargo as fuel subject to IGC requirements and applicable additional guidance |
