DSI ALTAIR against its type
Built in 2016, it is 4 years newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 34,300 gross tonnage it is smaller than 54% 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 121 other vessels here, 78 of them bulk carriers. Its MRV returns name it STH SYDNEY for 2018–2020 and DSI ALTAIR for 2023–2025. The returns for 2018–2025 all give Majuro as port of registry.
Its 3,162 t of CO₂ for 2025 is close to the median of 3,238 t among the 3,732 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 227.8 kg CO₂, 13% below the type median of 260.7 kg. It logged 1,305 hours at sea against a median of 1,199 hours for its type that year. 2.4% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 4 years with reported emissions, the highest was 2020 (5,895 t) and the lowest 2023 (276 t). Its efficiency percentile within the type went from 19 in 2018 to 73 in 2025 (lower is more efficient). Of the 5 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 2,364 of 3,241 qualifying bulk carriers by EEOI, at the 73rd percentile. The dashed line is the type median, 7.6; this vessel reported 9.4.
EEOI divides emissions by transport work, which for this vessel and year was 334,987,288 tonne-miles over 13,885 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 5.8% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2021, 2022, 2024, so the series has gaps.
From 2023 to 2025, emissions rose 1,045.8% and CO₂ per nautical mile rose 19.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
