ISM company (DoC holder) in 2025: Merman Maritime Co
2019 at a glance
From the 2019 THETIS-MRV report. Carries about 10,007 t of cargo on average.
Within the chemical tanker fleet, 2025
Set against all 1,460 chemical tanker ships with a full-year 2025 report. Bigger ships burn more per mile but less per tonne of cargo, so read fuel per mile with the ship's size in mind.
Where the emissions happen, 2019
THETIS splits each ship's CO₂ by voyage type. The split sets how much falls under the EU ETS: all of it within the EU and at berth, half of it on voyages into or out of the EU.
- Between EU ports13%
- From the EU39%
- Into the EU46%
- At berth in the EU2%
Over the years
Full-year reports only. The Chemical tanker median is the middle ship of all chemical tanker ships reporting that year; it moves with the fleet, so a ship can gain on it without changing itself.

| 2022→2023 | −0.4 kn | −2% | −8% | −9% | −32% | 0.4 kn slower, fuel per mile down 2%; worse than speed alone explains (fouling, weather, loading or trade). |
| 2021→2022 | +0.9 kn | +3% | +15% | −13% | +46% | 0.9 kn faster, fuel per mile up 3%; better than speed alone explains (hull, engine or trade). |
| 2020→2021 | −2.3 kn | +2% | −20% | +88% | +29% | 2.3 kn slower, fuel per mile up 2%; worse than speed alone explains (fouling, weather, loading or trade). |
| 2019→2020 | −1.1 kn | +0% | −9% | −39% | −20% | 1.1 kn slower, fuel per mile flat; worse than speed alone explains (fouling, weather, loading or trade). |
Fuel per mile rises roughly with the square of speed for a given ship, so a change in speed explains much of a change in fuel per mile.
Every reporting year
One row per THETIS-MRV report. A ship that changed operator during a year has a part-year report for each.

Fuel per mile and CO₂ per tonne-mile are the ship's own reported KPIs. Chemical tanker ships are benchmarked on CO₂ per transport work (cargo) (TW), in g CO₂/t·nm. CO₂eq adds methane and nitrous oxide and is in the public files from 2024. Rank counts from the lowest figure among that year's chemical tanker ships. Methods: A delivery notes, B tank monitoring, C flow meters, D direct measurement. FuelEU GHG intensity is not shown: it needs fuel types, which the public file does not carry. Operators are named only from 2024, the first year the public files carry them; earlier years belong to the ship, not to any company.
