How VesselChain works

How VesselChain works

VesselChain is a green corridor fuel verification platform: a shared record where each bunker delivery is uploaded once, signed by an accredited verifier, and held identically by every partner in the corridor. It cannot be edited afterwards, including by us.

Three steps, one record

1 · Upload

After each refuelling the shipowner uploads the Bunker Delivery Note, the document stating what fuel went on board: grade, quantity, supplier, date and place of delivery.

2 · Verify

An independent verifier checks the data and signs it into the record. This is not a role we invented: FuelEU Maritime already requires accredited verifiers to approve monitoring plans and compliance balances. What has been missing is a shared place for that signature to live.

3 · Share

Once signed, the entry is copied identically to every corridor partner. Ports, shipowners, fuel suppliers, verifiers and regulators all read the same record, at the same time, in the same form.

Why a shared ledger and not a database

A database has an owner. Whoever runs it can edit it, and everyone else is being asked to trust that they will not.

That is workable when one company leads a project. A green corridor has no lead company: it is five kinds of partner who compete elsewhere and cooperate on one route. Asking four of them to trust the fifth one’s server is a governance problem, not a technical one.

A shared ledger removes the question. There is no copy to trust, because every partner holds the same one.

VesselChain runs on Ignis, a blockchain developed by Jelurida. Each verified delivery is written once and referenced by a hash, so any partner can confirm that the entry they hold is the entry that was signed.

What each partner sees

  • Shipowners and operators upload deliveries and export audit-ready evidence for their compliance reporting
  • Fuel suppliers confirm what was delivered, in their own words, on the record
  • Accredited verifiers review and sign entries, with every signature timestamped
  • Ports see the fuel activity on their corridor without owning the system that records it
  • Regulators and auditors read a chain of evidence that nobody could have edited after the fact

What the platform does not do

Being precise about this matters more than the feature list.

  • It does not measure fuel. It records what the Bunker Delivery Note states and who signed for it
  • It does not verify on anyone’s behalf. Verification is performed by the accredited third party the regulation already requires
  • It does not certify fuel as sustainable. That is the job of the certification schemes behind a Proof of Sustainability
  • It does not replace your reporting obligations. It gives you evidence that survives an audit

Where the platform is today

The MVP is live and running on Ignis. It handles vessel management, delivery upload, verifier signature and export.

We have not yet run a paid pilot inside an operational corridor, and that is exactly what we are looking for. If you are part of a corridor consortium, talk to us and we will scope your route in one call. A demo is available on request.

Are you an accredited verifier?

The signature step depends on accredited verifiers, and we are looking for verification partners. See how signing works.
