KATHARINA against its type

Built in 2012, it is 4 years newer than the median container ship on this register, which was built in 2008 (3,088 vessels with a known build year). At 10,318 gross tonnage it is smaller than 88% of the other 3,000 container ships with a recorded tonnage. It is one of 307 container ships here under the Portugal flag, 8.8% of the 3,495 on the register. Its MRV returns name it KATHARINA SCHEPERS for 2019–2024 and KATHARINA for 2025. The reported port of registry changed: Limasol (2019), then Limassol (2020), then Madeira (2021–2025).

Its 12,946 t of CO₂ for 2025 is 21% below the median of 16,359 t among the 2,234 container ships on this register that reported for 2025. Per nautical mile it emitted 251.3 kg CO₂, 54% below the type median of 545.6 kg. It logged 4,123 hours at sea against a median of 3,155 hours for its type that year. 8.1% of its 2025 emissions were at berth; the median for container ships was 3.2%. Across 7 years with reported emissions, the highest was 2023 (15,260 t) and the lowest 2022 (12,225 t). Its efficiency percentile within the type went from 85 in 2019 to 94 in 2025 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,729 of 1,838 qualifying container ships by EEOI, at the 94th percentile. The dashed line is the type median, 14.2; this vessel reported 44.0.

Reported CO₂ in 2025 was 15.0% lower than in 2019, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 10.1% while distance sailed fell 12.3%and CO₂ per nautical mile rose 2.6%.That points mainly to how much the vessel sailed, rather than the other.

Sources and how to read this

This page draws on 7 MRV reporting years, an efficiency ranking, 4 of 5 vessel particulars, a name history and a licensed photograph. Not found in the sources for this vessel: AIS movements in Norwegian waters, a sanctions listing and US port state inspections.

Empty means unreported, never zero. How EEOI, distance, percentiles and sister ships are handled is explained under reading a vessel page. Something wrong? See corrections.
