DEVBULK SADIYE against its type
Built in 2015, it is 8 years newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). It is one of 181 general cargo ships here under the Marshall Islands flag, 5.9% of the 3,081 on the register. Maestro Shipping is linked to 2 vessels on this register. Its MRV returns name it MAESTRO DIAMOND for 2018–2022 and DEVBULK SADIYE for 2023–2025. The returns for 2018–2025 all give Majuro as port of registry.
Its 1,014 t of CO₂ for 2025 is 64% below the median of 2,820 t among the 2,469 general cargo ships on this register that reported for 2025. Per nautical mile it emitted 154.2 kg CO₂, 26% above the type median of 122.2 kg. It logged 623 hours at sea against a median of 3,044 hours for its type that year. 2.4% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 8 years with reported emissions, the highest was 2019 (6,949 t) and the lowest 2023 (394 t). Its efficiency percentile within the type went from 84 in 2018 to 73 in 2022 (lower is more efficient). Of the 5 comparable vessels listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2022
Position 2,685 of 3,692 qualifying bulk carriers by EEOI, at the 73rd percentile. The dashed line is the type median, 8.4; this vessel reported 10.8.
EEOI divides emissions by transport work, which for this vessel and year was 451,596,279 tonne-miles over 22,545 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 85.0% lower than in 2018, for EU/EEA voyages only.
From 2024 to 2025, emissions fell 79.6% and CO₂ per nautical mile fell 13.5%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
