DEVBULK SERVET against its type
It is one of 181 general cargo ships here under the Marshall Islands flag, 5.9% of the 3,081 on the register. Its MRV returns name it MAESTRO SAPPHIRE for 2020–2023 and DEVBULK SERVET for 2024–2025. The returns for 2020–2025 all give Majuro as port of registry.
Its 3,484 t of CO₂ for 2024 is 14% below the median of 4,046 t among the 1,395 general cargo ships on this register that reported for 2024. Per nautical mile it emitted 191.7 kg CO₂, close to the type median of 187.0 kg. It logged 1,518 hours at sea against a median of 2,074 hours for its type that year. 3.6% of its 2024 emissions were at berth; the median for general cargo ships was 3.9%. Across 5 years with reported emissions, the highest was 2022 (6,392 t) and the lowest 2020 (924 t). Its efficiency percentile within the type went from 36 in 2021 to 83 in 2023 (lower is more efficient). The one comparable vessel listed below with a 2024 return reported a higher or equal CO₂ per nautical mile.
No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2023
Position 2,715 of 3,262 qualifying bulk carriers by EEOI, at the 83rd percentile. The dashed line is the type median, 8.0; this vessel reported 12.0.
EEOI divides emissions by transport work, which for this vessel and year was 524,736,007 tonne-miles over 28,610 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 277.0% higher than in 2020, for EU/EEA voyages only.
From 2023 to 2024, emissions fell 44.5% and CO₂ per nautical mile fell 12.7%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
