DORTHE OLDENDORFF against its type

Built in 2019, it is 12 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 24,726 gross tonnage it is larger than 92% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 216 general cargo ships here under the Liberia flag, 7.0% of the 3,081 on the register. Its MRV returns name it DORTHE OLDENDORFF for 2021 and HG ROTTERDAM for 2023–2025. The returns for 2021–2025 all give Monrovia as port of registry.

Its 576 t of CO₂ for 2025 is 80% below 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 260.7 kg CO₂, 2.1 times the type median of 122.2 kg. It logged 191 hours at sea against a median of 3,044 hours for its type that year. 7.3% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 4 years with reported emissions, the highest was 2024 (6,752 t) and the lowest 2025 (576 t). Its efficiency percentile within the type went from 62 in 2021 to 8 in 2024 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ in 2025 was 81.0% lower than in 2021, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.

From 2024 to 2025, emissions fell 91.5% and CO₂ per nautical mile rose 2.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.

Sources and how to read this

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