PREVAIL STAR against its type
Built in 2014, it is 2 years newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 44,043 gross tonnage it is larger than 76% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 1,601 bulk carriers here under the Panama flag, 19.7% of the 8,138 on the register. The same builder is recorded for 160 other vessels here, 68 of them bulk carriers. Its MRV returns name it STELLA DORA for 2019–2020 and PREVAIL STAR for 2022–2025. The reported port of registry changed: Singapore (2019–2020), then PANAMA (2022–2025).
Its 12,499 t of CO₂ for 2025 is 3.9 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 317.9 kg CO₂, 22% above the type median of 260.7 kg. It logged 4,767 hours at sea against a median of 1,200 hours for its type that year. 3.0% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 5 years with reported emissions, the highest was 2025 (12,499 t) and the lowest 2020 (2,242 t). Its efficiency percentile within the type went from 30 in 2019 to 50 in 2025 (lower is more efficient). Of the 7 sister ships listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,617 of 3,241 qualifying bulk carriers by EEOI, at the 50th percentile. The dashed line is the type median, 7.6; this vessel reported 7.6.
EEOI divides emissions by transport work, which for this vessel and year was 1,648,920,844 tonne-miles over 39,314 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 83.3% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2021, 2024, so the series has gaps.
From 2023 to 2025, emissions rose 46.6% while distance sailed rose 47.4%and CO₂ per nautical mile fell 0.5%.That points mainly to how much the vessel sailed, rather than the other.
