FuelEU Maritime and the EU MRV framework both require an accredited verifier to approve what a shipping company reports. VesselChain is a maritime verifier platform where that approval is recorded: one entry per fuel delivery, signed once, visible to everyone who depends on it.

This page is written for verification bodies. We are looking for verification partners, and it is worth being direct about what that would and would not involve.

What you would be signing

A single delivery entry. It contains what the Bunker Delivery Note states: vessel and IMO number, date and place of delivery, supplier, fuel grade, quantity, and where applicable the reference to a Proof of Sustainability certificate.

Your signature attests to one thing: that the entry matches the documentation you reviewed. It does not extend to the physical properties of the fuel, to the accuracy of the supplier’s measurement, or to the vessel’s wider compliance position.

The scope of the signature is the scope of your review. Nothing in the record widens it.

What it does not change

• It does not replace your verification methodology. You work how you work
• It does not make VesselChain a verifier. We do not verify anything, and we never will
• It does not create an obligation to sign. An unsigned entry simply stays unsigned, and it is visible as such
• It does not lock the shipping company in. The record is theirs and their partners’, not ours

Why a shared record helps your side of the work

Verification of fuel data usually means chasing documents. A Bunker Delivery Note sits with the vessel, the Proof of Sustainability with the supplier, the voyage records with the operator, and each arrives in a different format at a different moment.

When the entry is created at the point of delivery instead of reconstructed afterwards, three things change:

• The evidence is already assembled when it reaches you, rather than gathered on request
• Nothing can have changed since. Entries are written once and cannot be edited, including by us
• Your signature is durable. What you signed is what any auditor will see, years later, without depending on anyone keeping a file

Where this matters most

Inside a green shipping corridor, several organisations have to report from the same figures with no lead company between them. Ports, shipowners, fuel suppliers and regulators all need the same evidence, and today each one holds a different copy of it.

A verifier working in that setting is asked to sign off numbers whose provenance is spread across five parties. A neutral record is not a convenience there, it is what makes the verification defensible.

Where the platform is today

The MVP is live and runs on the Ignis blockchain. It handles vessel management, delivery upload, verifier signature and export. See how it works.

We have not yet run a paid pilot inside an operational corridor, and no verification body has signed entries in production. That is precisely the gap we are trying to close, and we would rather say so than imply otherwise.

What we are asking

A conversation, not a commitment. Specifically:

• Whether the entry structure matches what you actually review
• What your signature would need to say, and what it must not be read to say
• What would have to be true for you to sign inside a pilot corridor

If that is a conversation worth having, write to us and we will keep it short.
