OLGA against its type
Built in 1996, it is 16 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 11,121 gross tonnage it is smaller than 98% 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 95 other vessels here, 64 of them bulk carriers. The returns for 2018–2025 all give Monrovia as port of registry.
Its 4,087 t of CO₂ for 2025 is 26% 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 196.7 kg CO₂, 25% below the type median of 260.7 kg. It logged 2,169 hours at sea against a median of 1,200 hours for its type that year. 2.4% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 8 years with reported emissions, the highest was 2018 (8,393 t) and the lowest 2022 (924 t). Its efficiency percentile within the type went from 97 in 2019 to 100 in 2025 (lower is more efficient). Of the 5 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 3,225 of 3,241 qualifying bulk carriers by EEOI, at the 100th percentile. The dashed line is the type median, 7.6; this vessel reported 27.9.
EEOI divides emissions by transport work, which for this vessel and year was 146,441,061 tonne-miles over 20,782 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 51.3% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 3.2% while distance sailed fell 5.9%and CO₂ per nautical mile rose 2.8%.That points mainly to how much the vessel sailed, rather than the other.
