FEDERAL MAYUMI against its type

Built in 2012, it is the same age as the median bulk carrier on this register (build year 2012, 6,882 vessels with a known build year). 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 468 other vessels here, 362 of them bulk carriers. Fednav Limited is linked to 27 vessels on this register. The returns for 2018–2025 all give Majuro as port of registry.

Its 5,926 t of CO₂ for 2025 is 1.8 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 189.2 kg CO₂, 27% below the type median of 260.7 kg. It logged 2,886 hours at sea against a median of 1,200 hours for its type that year. 7.4% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 8 years with reported emissions, the highest was 2020 (8,934 t) and the lowest 2019 (4,070 t). Its efficiency percentile within the type went from 90 in 2018 to 72 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 1 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 2,323 of 3,241 qualifying bulk carriers by EEOI, at the 72nd percentile. The dashed line is the type median, 7.6; this vessel reported 9.3.

Across the 16 ranked vessels operated by Fednav Limited, the median percentile is 66. This vessel is less efficient than its own fleet median.

EEOI divides emissions by transport work, which for this vessel and year was 637,854,682 tonne-miles over 31,328 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 5.0% higher than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 26.7% while distance sailed rose 18.4%and CO₂ per nautical mile rose 7.0%.That points mainly to how much the vessel sailed, rather than the other.
