VesselChain builds neutral verification infrastructure for green shipping corridors. Every bunker delivery is recorded once, at the point of delivery, signed by an accredited verifier, and held identically by every partner that depends on it.
The problem we work on
A green shipping corridor is an agreement between parties with no shared parent company. Ports, shipowners, fuel suppliers and verifiers all record the same bunker delivery separately, and none of them can impose their database on the others.
That was a coordination problem for years. It became a financial one when European regulation started attaching a price to the same figures: FuelEU Maritime penalises a greenhouse gas intensity deficit at €2,400 per tonne of VLSFO equivalent, and EU ETS prices the emissions those fuels produce.
The measurement obligation is old. What is new is that the same number is now read by a class society, a flag state, an EU verifier and a corridor partner, each holding their own copy.
Our approach
VesselChain is built so that no participant owns the register. Once an entry is signed it cannot be altered by any party, and that constraint applies to a port, to a charterer and to us equally.
- Recorded once. The delivery is entered at the point of bunkering, from the document already signed there
- Signed by an accredited verifier. Not a service we provide: the independent third party that the regulation already requires
- Read by everyone. Each partner works from the same entry instead of reconstructing it separately
The full mechanics, including what each partner sees and what the platform deliberately does not do, are set out on the platform page. The platform runs on the Ignis blockchain, and a demo is available on request.
The founders
VesselChain sits between two industries that rarely share a room: marine infrastructure and distributed systems. It was founded by people who work in both.
Francisco Sarrias · Co-founder
Telecommunications engineer with over 30 years in marine infrastructure, working on floating structures for ports, offshore aquaculture and marine renewable energy. He brings more than 10 years in blockchain to that, and sits on an international committee revising design and operational guidelines for marine facilities.
Borja Sarrias · Co-founder and Chief Marketing Officer
Technology consultant by background, implementing the enterprise systems that large companies run their compliance reporting on. That is the perspective he brings here: a verification record is only useful if it fits the systems a shipowner already operates, and if the people who file the report can produce the evidence without assembling it by hand.
