KIRSTEN OLDENDORFF against its type
Built in 2020, it is 8 years newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 44,109 gross tonnage it is larger than 77% 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. The same builder is recorded for 118 other vessels here, 105 of them bulk carriers. The returns for 2023–2025 all give Monrovia as port of registry.
Its 4,282 t of CO₂ for 2025 is 32% above the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 300.6 kg CO₂, 15% above the type median of 260.7 kg. It logged 1,198 hours at sea against a median of 1,200 hours for its type that year. 4.1% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 3 years with reported emissions, the highest was 2023 (8,369 t) and the lowest 2025 (4,282 t). Its efficiency percentile within the type went from 23 in 2023 to 42 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,365 of 3,241 qualifying bulk carriers by EEOI, at the 42nd percentile. The dashed line is the type median, 7.6; this vessel reported 7.1.
EEOI divides emissions by transport work, which for this vessel and year was 605,701,556 tonne-miles over 14,246 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 48.8% lower than in 2023, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 46.2% while distance sailed fell 48.0%and CO₂ per nautical mile rose 3.5%.That points mainly to how much the vessel sailed, rather than the other.
