FEDERAL KATSURA against its type
Built in 2005, it is 7 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 19,165 gross tonnage it is smaller than 92% 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 same builder is recorded for 307 other vessels here, 48 of them bulk carriers. The returns for 2018–2025 all give Majuro as port of registry.
Its 7,598 t of CO₂ for 2025 is 2.3 times the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 205.6 kg CO₂, 21% below the type median of 260.7 kg. It logged 3,475 hours at sea against a median of 1,200 hours for its type that year. 6.9% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 7 years with reported emissions, the highest was 2025 (7,598 t) and the lowest 2023 (2,454 t). Its efficiency percentile within the type went from 77 in 2018 to 82 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 2,671 of 3,241 qualifying bulk carriers by EEOI, at the 82nd percentile. The dashed line is the type median, 7.6; this vessel reported 10.8.
EEOI divides emissions by transport work, which for this vessel and year was 701,594,644 tonne-miles over 36,949 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 34.3% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2020, so the series has gaps.
From 2024 to 2025, emissions rose 37.9% while distance sailed rose 39.3%and CO₂ per nautical mile fell 1.0%.That points mainly to how much the vessel sailed, rather than the other.
