OAK BAY against its type
Built in 2013, it is 1 year newer than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 31,749 gross tonnage it is smaller than 66% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 637 bulk carriers here under the Hong Kong flag, 7.8% of the 8,138 on the register. The same builder is recorded for 468 other vessels here, 362 of them bulk carriers. The returns for 2020–2025 all give Hong Kong, China as port of registry.
Its 2,529 t of CO₂ for 2025 is 22% below the median of 3,239 t among the 3,731 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 256.2 kg CO₂, close to the type median of 260.7 kg. It logged 962 hours at sea against a median of 1,200 hours for its type that year. 2.3% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 3 years with reported emissions, the highest was 2020 (5,464 t) and the lowest 2024 (1,195 t). Its efficiency percentile within the type went from 18 in 2020 to 34 in 2025 (lower is more efficient). Of the 6 sister ships listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,104 of 3,241 qualifying bulk carriers by EEOI, at the 34th percentile. The dashed line is the type median, 7.6; this vessel reported 6.5.
EEOI divides emissions by transport work, which for this vessel and year was 387,822,086 tonne-miles over 9,869 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 53.7% lower than in 2020, for EU/EEA voyages only. No return is recorded for 2021, 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions rose 111.5% while distance sailed rose 128.7%and CO₂ per nautical mile fell 7.5%.That points mainly to how much the vessel sailed, rather than the other.
