Marine & Maritime
Lower fuel cost on every voyage
For vessel owners, fishing fleets and harbour operators facing rising bunker costs and emissions rules.
The challenge
Where the fuel goes, and the margin with it
Fuel is the biggest cost most marine & maritime operations can still control. Here is what we hear from teams like yours.
Bunker fuel is the biggest voyage cost
Every tonne of fuel saved goes straight to the voyage result.
Emissions rules keep tightening
Carbon intensity ratings and port rules put fuel efficiency on the charterer's checklist.
Every vessel is different
Hull, engines and routes vary, so savings have to be proved vessel by vessel.
Limited time alongside
Anything new must fit into bunkering and normal watchkeeping, not add work.

The DeCarb formulation for marine & maritime
How we measure
Measured on your machines. Not in a brochure.
One vessel, its own history. We compare fuel per day or per nautical mile on comparable voyages before and during the trial, from the engine-room log.
Units we reportfuel per day · per voyage · per nautical mile
Baseline
We read your own fuel and output records and set the starting point with your team.
Controlled trial
The same equipment runs on DeCarb under normal duty, logged the same way.
Signed result
You get a before-and-after report in fuel/day, ready for management and ESG reporting.
Proof in this sector
Your operation could be the first case study
We have not yet published a marine & maritime case study. Run a measured trial with us and the result is yours, in your own units.
Trial on one vessel first, measured per day and per voyage.Free assessment, controlled trial, signed result. Then you decide.

Works with the vessels you run today
No new engines, no new burners, no capital project. DeCarb goes into the fuel you already buy.
- Fishing trawlers and boats
- Tugs and harbour craft
- Ferries and passenger boats
- Coastal cargo vessels
- Offshore supply vessels
- Auxiliary engines and gensets on board
How does a vessel trial work?
We pick one vessel, use its engine-room log as the baseline, and compare fuel per day or per nautical mile on comparable voyages during the trial.
Which product is used on vessels?
DeCarb Marine Plus, formulated for marine diesel engines. It is dosed at bunkering or into the service tank.
Can the data support CII reporting?
Yes. Measured fuel per day and per voyage feeds straight into carbon intensity calculations and your emissions records.
