Alternative Fuels and Operational Readiness
Readiness starts from the actual fuel approval route: mandatory IGF provisions for natural gas; for other fuels SOLAS II-1/55, applicable interim guidance and flag/RO requirements.
Operational Explanation
Readiness starts from the actual fuel approval route: mandatory IGF provisions for natural gas; for other fuels SOLAS II-1/55, applicable interim guidance and flag/RO requirements.
Regulatory Reference
IGF Code natural gas; SOLAS II-1/55 alternative design; fuel-specific IMO interim guidelines.
Scope of Application
Methanol, ammonia, hydrogen and LPG are not generically labelled IGF Code compliant.
Procedure / How to Complete It
- Identify fuel, ship type and prescriptive coverage.
- Choose mandatory or alternative-design route.
- Apply the correct fuel/cargo-as-fuel circular.
- Obtain approval, training, bunkering and emergency arrangements.
- Prepare PSC evidence for the actual route.
Practical Example
A methanol ship uses approved alternative design and MSC.1/Circ.1621, not a generic IGF compliance label.
What Typically Goes Wrong
Applying IGF Code compliance indiscriminately to ammonia, hydrogen, methanol and LPG.
Common Mistakes Mistake Library
| Mistake | Consequence | How to Avoid It |
|---|---|---|
| Applying IGF Code compliance indiscriminately to ammonia, hydrogen, methanol and LPG. | Non-compliant decision or treatment | Follow the approved arrangement and applicable sources |

- Do not improvise tests, thresholds or intervals.
- Record deviations and corrective action.
Preparation checklist
