Alternative Fuels and Operational Readiness
LNG, methanol, ammonia: every alternative fuel brings its own set of specific operational risks, governed by the IGF Code, which must be addressed before adoption, not after.
Operational Explanation
The transition to lower-carbon fuels (LNG, methanol, ammonia, hydrogen) requires specific operational preparation that goes well beyond installing the propulsion system: bunkering, storage, emergency management and crew training must be adapted to the specific risk characteristics of each fuel, often very different from those of conventional fuel.
The IGF Code (International Code of Safety for Ships using Gases or other Low-flashpoint Fuels) provides the regulatory framework for the use of these fuels, but its practical application requires specific competencies that the industry is still developing at scale, with significant differences in technological and regulatory maturity between the various alternative fuels.
Regulatory Reference
SOLAS Chapter II-1, Part G makes the IGF Code mandatory for ships using gases or other low-flashpoint fuels; additional fuel-type-specific requirements are under continuous development at the IMO, given the rapid technological evolution of the sector.
Scope of Application
Every ship that uses or plans to use alternative fuels (LNG, methanol, ammonia, hydrogen) as a primary or dual fuel alongside conventional fuel.
Procedure / How to Complete It
- Assess the technological and regulatory maturity of the alternative fuel under consideration, since it varies significantly (LNG relatively mature, ammonia and hydrogen at a more experimental stage).
- Verify compliance with the IGF Code for the storage, distribution and use systems of the specific fuel on board.
- Develop fuel-specific bunkering procedures, considering the toxicity, flammability or cryogenic characteristics specific to each fuel.
- Train the crew on the specific risks of the fuel used (e.g. ammonia toxicity, LNG cryogenic temperatures), not generically on 'alternative fuels'.
- Prepare specific emergency procedures (e.g. handling an ammonia spill, handling an LNG gas release) distinct from those for conventional fuel.
Practical Example
Preparation example: a dual-fuel LNG/conventional fuel ship, with the crew specifically trained on cryogenic bunkering procedures and on managing gas-release emergencies, distinct from the traditional bunkering procedures already familiar to them.
Real Cases
Common Mistakes Mistake Library
| Mistake | Consequence | How to avoid it |
|---|---|---|
| Crew trained generically on 'alternative fuels' instead of specifically on the fuel actually used | Personnel not adequately prepared for the specific risks of the actual fuel on board | Always train specifically on the fuel actually installed, not generically |
| Emergency procedures borrowed from conventional fuel without adaptation | Inadequate response to an emergency with different specific risk characteristics (toxicity, cryogenics) | Develop specific emergency procedures for every alternative fuel used |
| Adoption of an alternative fuel without assessing the maturity of bunkering infrastructure on planned routes | Operational difficulties in fuel supply | Assess the fuel's infrastructure availability on planned operating routes before adoption |
PSC Observations
Operational Tips
- Always train the crew specifically on the fuel actually installed on board, not generically on alternative fuels.
- Develop dedicated emergency procedures for every alternative fuel, rather than merely adapting existing conventional fuel procedures.
- Assess the maturity of bunkering infrastructure on planned operating routes before adopting a new fuel.
Checklist
- IGF Code compliance verified for the fuel's storage/distribution systems
- Fuel-specific bunkering procedures developed
- Crew specifically trained on the risks of the actual fuel on board
- Dedicated emergency procedures prepared for the specific fuel
- Fuel infrastructure availability verified for operating routes
