CAPTAIN MIKE 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 46,982 gross tonnage it is larger than 82% 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 87 other vessels here, 60 of them bulk carriers. The returns for 2019–2023 all give Majuro as port of registry.
Its 1,557 t of CO₂ for 2023 is 54% below the median of 3,386 t among the 3,573 bulk carriers on this register that reported for 2023. Per nautical mile it emitted 363.0 kg CO₂, 33% above the type median of 272.6 kg. It logged 422 hours at sea against a median of 1,186 hours for its type that year. 8.4% of its 2023 emissions were at berth; the median for bulk carriers was 4.3%. Across 4 years with reported emissions, the highest was 2022 (9,459 t) and the lowest 2023 (1,557 t). Its efficiency percentile within the type went from 15 in 2019 to 54 in 2022 (lower is more efficient). The one sister ship listed below with a 2023 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2022
Position 1,974 of 3,692 qualifying bulk carriers by EEOI, at the 54th percentile. The dashed line is the type median, 8.4; this vessel reported 8.7.
EEOI divides emissions by transport work, which for this vessel and year was 1,085,977,038 tonne-miles over 25,384 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2023 was 61.7% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.
From 2022 to 2023, emissions fell 83.5% and CO₂ per nautical mile fell 2.6%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
