ANTONIA against its type

Built in 2012, it is 5 years newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 6,351 gross tonnage it is larger than 50% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 306 general cargo ships here under the Netherlands flag, 9.9% of the 3,081 on the register. Its MRV returns name it ANTONIA for 2019–2020 and ONEGO DUERO for 2021–2025. The reported port of registry changed: Helsinki (2019–2020), then Rotterdam (2021–2025).

Its 4,744 t of CO₂ for 2025 is 1.7 times the median of 2,820 t among the 2,469 general cargo ships on this register that reported for 2025. Per nautical mile it emitted 140.0 kg CO₂, 15% above the type median of 122.2 kg. It logged 3,208 hours at sea against a median of 3,044 hours for its type that year. 2.3% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 7 years with reported emissions, the highest was 2020 (6,112 t) and the lowest 2021 (3,181 t). Its efficiency percentile within the type went from 56 in 2019 to 65 in 2022 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2022

Position 263 of 406 qualifying general cargo ships by EEOI, at the 65th percentile. The dashed line is the type median, 23.3; this vessel reported 29.2.

0255075100more efficientless efficientThis vessel: 65th percentile, EEOI 29.2

EEOI divides emissions by transport work, which for this vessel and year was 147,714,481 tonne-miles over 32,323 nautical miles.

Reported CO₂ in 2025 was 17.5% lower than in 2019, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 6.8% and CO₂ per nautical mile rose 13.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.

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