DOROTHEA OLDENDORFF against its type
Built in 2009, it is 3 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 19,992 gross tonnage it is smaller than 90% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 1,589 bulk carriers here under the Liberia flag, 19.5% of the 8,138 on the register. Its MRV returns name it DOROTHEA OLDENDORFF for 2018 and IVORY GULL for 2019–2025. The returns for 2019–2025 all give Monrovia as port of registry.
Its 3,425 t of CO₂ for 2025 is close to the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 222.3 kg CO₂, 15% below the type median of 260.7 kg. It logged 1,377 hours at sea against a median of 1,200 hours for its type that year. 2.8% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 8 years with reported emissions, the highest was 2019 (9,021 t) and the lowest 2021 (1,966 t). Its efficiency percentile within the type went from 77 in 2018 to 59 in 2025 (lower is more efficient). Of the 4 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,925 of 3,241 qualifying bulk carriers by EEOI, at the 59th percentile. The dashed line is the type median, 7.6; this vessel reported 8.3.
EEOI divides emissions by transport work, which for this vessel and year was 413,091,677 tonne-miles over 15,404 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 24.0% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 22.8% while distance sailed fell 24.9%and CO₂ per nautical mile rose 2.9%.That points mainly to how much the vessel sailed, rather than the other.
