Methanol-Fuelled Ships: Underwriting the Fuel-System Change
Describe the actual fuel-system design, operating profile, approvals, supply arrangements and crew preparation, rather than changing only the vessel's fuel label.

What changes in an insurance enquiry for a methanol-fuelled ship?
Describe the actual fuel-system design, operating profile, approvals, supply arrangements and crew preparation, rather than changing only the vessel's fuel label. Underwriters need to understand the proposed operation and its property and liability interfaces. A conventional-fuel policy should not be assumed to address a conversion or new activity without the required disclosure and agreement.
Begin with the approved technical description
Lloyd's Register guidance on methyl and ethyl alcohol fuels provides technical context for these fuels. Guidance documents are not an insurance contract or approval of every vessel. Confirm the applicable class and flag requirements for the specific design through the responsible professionals.
Distinguish a newbuild, completed conversion and proposed conversion. Explain any remaining work, trials and operating limitations. Include the intended routes and bunkering arrangements; an approved system still has operational interfaces that need a clear description.
| Submission area | What to explain | Useful evidence |
|---|---|---|
| Design status | Approved scope and open conditions | Class and flag records |
| Conversion stage | Work, trials and delivery milestones | Yard and project schedule |
| Fuel supply | Specification and quality controls | Supplier arrangements |
| Operation | Bunkering locations and frequency | Intended trading profile |
| Personnel | Preparation for the actual equipment | Relevant training records |
Treat conversion milestones explicitly
In a fictional project, a vessel completes yard work but still needs trials before normal service. The owner assumes ordinary trading cover resumes when the repair invoice is paid. A better approach is to agree the relevant insurance milestones, trial arrangements and any conditions before movement begins.
Keep the yard contract, technical scope, test records and handover documentation aligned. If the programme or trial area changes, explain the revised facts to the relevant insurers rather than relying on a description that no longer matches the operation.
Avoid assumptions about fuel quality or environmental claims
Identify the fuel actually supplied and the contractual quality arrangements. Do not infer a fuel's full lifecycle emissions from the word methanol alone. Commercial environmental claims and marine insurance terms address different questions and require their own evidence.
Ask how hull damage, machinery issues, bunkering liabilities and any relevant exclusions are treated. Maintenance and emergency arrangements should come from qualified technical personnel; an insurance article is not an operating manual. Preserve accurate fuel, service and incident records so a future investigation can examine the facts.
Read the vessel insurance guide, explore hull and machinery cover, or provide the vessel and conversion details for review.
Key takeaways
- Describe the actual fuel system, approvals and operational profile.
- Agree insurance milestones for conversion, trials and return to service.
- Keep fuel-quality evidence and environmental claims separate from coverage assumptions.
