YASA SATURN against its type
Built in 2019, it is 7 years newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 34,508 gross tonnage it is smaller than 53% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 1,603 bulk carriers here under the Marshall Islands flag, 19.7% of the 8,138 on the register. The returns for 2021–2025 all give MAJURO as port of registry.
Its 3,463 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 234.7 kg CO₂, close to the type median of 260.7 kg. It logged 1,312 hours at sea against a median of 1,200 hours for its type that year. 1.9% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 4 years with reported emissions, the highest was 2025 (3,463 t) and the lowest 2024 (328 t). Its efficiency percentile within the type went from 44 in 2021 to 22 in 2025 (lower is more efficient). Of the 7 comparable vessels listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 718 of 3,241 qualifying bulk carriers by EEOI, at the 22nd percentile. The dashed line is the type median, 7.6; this vessel reported 5.7.
EEOI divides emissions by transport work, which for this vessel and year was 605,337,413 tonne-miles over 14,752 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 105.8% higher than in 2021, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.
From 2024 to 2025, emissions rose 956.9% and CO₂ per nautical mile fell 11.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
