As the shipping industry moves toward cleaner, low-carbon fuels, more vessels are running on gases and other low-flashpoint fuels such as LNG, methanol, LPG and hydrogen. These fuels bring real environmental benefits -but they also introduce hazards that conventional oil-fuelled ships never had to manage. That is exactly why the IGF Code course exists: to make sure seafarers working on these ships know how to handle the fuel safely.
This guide explains what the IGF Code is, how the Basic and Advanced training levels differ, and who is required to complete them.
What is the IGF Code?
IGF stands for the International Code of Safety for Ships Using Gases or Other Low-Flashpoint Fuels. It was adopted by the International Maritime Organization (IMO) and entered into force on 1 January 2017. The Code sets mandatory design, construction and operational standards for ships that use low-flashpoint fuels -that is, fuels with a flashpoint below the traditional 60°C threshold.
In simple terms, the IGF Code covers gas-fuelled ships (other than gas carriers, which fall under the separate IGC Code). As LNG bunkering infrastructure grows and owners commit to decarbonisation, the number of IGF Code ships in the global fleet continues to rise -and with it, the demand for properly trained crew.
Why IGF Code training is mandatory
Handling low-flashpoint fuel is not the same as handling heavy fuel oil. Gases can be cryogenic, they can form flammable or toxic vapour clouds, and they behave very differently during bunkering and in an emergency. Recognising this, the STCW Convention (as amended in Manila) introduced mandatory training requirements under Regulation V/3 and Section A-V/3.
Under these rules, seafarers serving on IGF Code ships must hold evidence of the appropriate level of training before they take up their duties. There are two distinct levels.
Basic IGF Code training
Basic training for IGF Code ships is intended for seafarers who have safety or operational duties associated with the fuel and fuel systems, but who are not in immediate charge of the fuel’s use.
Typical topics covered in a Basic IGF Code course include:
- The properties and hazards of low-flashpoint fuels
- Fundamentals of ship fuel and fuel-handling systems
- Safe bunkering and gas-handling procedures
- Fire prevention, firefighting and controlling leaks
- Personal safety, protective equipment and safe working practices
- Basic emergency response
This level gives ratings and support crew the foundational awareness they need to work safely around low-flashpoint fuel systems.
Advanced IGF Code training
Advanced training for IGF Code ships is aimed at masters, engineer officers and any personnel with immediate responsibility for the care and use of fuels and fuel systems on board.
An Advanced IGF Code course builds on the Basic content and goes deeper into:
- Detailed operation and monitoring of fuel systems and control equipment
- Safe management of bunkering operations
- Precautions to prevent hazards specific to low-flashpoint fuels
- Managing emergencies, including gas leaks, fire and system failures
- Regulatory and documentation requirements
- Risk assessment and safe-work planning for fuel operations
Because these officers make the real-time decisions that keep the vessel safe, the Advanced level demands a stronger, hands-on understanding of the systems involved.
Basic vs Advanced IGF Code: which one do you need?
The level you require depends on your rank and shipboard responsibilities:
- If you have general safety duties related to the fuel system, Basic IGF Code training is typically the requirement.
- If you have immediate responsibility for the fuel and its systems -such as engineers and senior officers -the Advanced level applies.
Many seafarers building a career on gas-fuelled vessels ultimately complete both, progressing from Basic to Advanced as they take on more responsibility.
Preparing for a future of alternative fuels
The shift toward LNG, methanol and other low-flashpoint fuels is one of the defining trends in modern shipping. Officers and ratings who hold IGF Code certification are positioning themselves for the vessels that will dominate the coming decades. Simulator-based and practical training is particularly valuable here, because it lets crews rehearse bunkering and emergency scenarios in a safe, controlled environment before they face them at sea.

Frequently asked questions
What is the IGF Code in simple terms? It’s the IMO’s safety code for ships that use gases or other low-flashpoint fuels such as LNG and methanol, covering how those ships are designed, built and operated.
Who needs IGF Code training? Seafarers serving on IGF Code ships. Those with general safety duties need Basic training; masters, engineers and anyone with immediate responsibility for the fuel need Advanced training.
What’s the difference between Basic and Advanced IGF Code training? Basic gives foundational awareness of fuel hazards and safe practices. Advanced covers detailed system operation, bunkering management and emergency response for those directly responsible for the fuel.
Is IGF Code training mandatory? Yes. Under STCW Regulation V/3, seafarers on IGF Code ships must hold the appropriate level of training before serving.
