Who we work with
Four kinds of shipowners, one question: how do we stay compliant without it eating our week?
For owner-captains. MRV without the Excel stress: we prepare, check and submit – you keep sailing.
For sustainability and technical managers. Know your ETS and FuelEU exposure before you pay.
Full ETS exposure, methane included – know your numbers. Small tankers: MRV is coming in 2029.
GM Premium Insight: real fuel and CO₂ insight for every voyage – measured, not estimated.
Why Green Maritime
The expertise of a captain, the reliability of validated data, and a team that takes the whole process off your plate.
Maritime compliance experts, not just software
Founded by a former captain. A direct line to class societies, verifiers and THETIS. We know what a port call looks like.
Validated data. Faster approval. No surprises.
Every entry is checked the moment it is entered. Verifiers get clean data; you get approval without correction rounds.
From data to approved report – we handle it
Flowmeters installed within days, around your port calls. One contact person from monitoring plan to THETIS upload.
How it works
1. A 20-minute call. We look at how you handle MRV, ETS and FuelEU today.
2. A pilot on one vessel. See how it works before you commit.
3. Installation around your port calls. Flowmeters fitted within days, no downtime.
4. Reporting and support. Validated data, verified reports, THETIS upload – one contact person.
