MEDUSA against its type

Built in 2010, it is 2 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 43,012 gross tonnage it is larger than 69% 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 360 other vessels here, 303 of them bulk carriers. The returns for 2023–2025 all give Majuro as port of registry.

Its 4,904 t of CO₂ for 2025 is 1.5 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 288.0 kg CO₂, 10% above the type median of 260.7 kg. It logged 1,453 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%. Its efficiency percentile within the type went from 91 in 2023 to 35 in 2025 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025

Position 1,123 of 3,241 qualifying bulk carriers by EEOI, at the 35th percentile. The dashed line is the type median, 7.6; this vessel reported 6.6.

EEOI divides emissions by transport work, which for this vessel and year was 746,479,452 tonne-miles over 17,029 nautical miles.

Reported CO₂ by year

2023: 3,023 t20233,0232025: 4,904 t20254,904

Reported CO₂ in 2025 was 62.2% higher than in 2023, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.

From 2023 to 2025, emissions rose 62.2% while distance sailed rose 67.1%and CO₂ per nautical mile fell 2.9%.That points mainly to how much the vessel sailed, rather than the other.
