AYANA STAR against its type
Built in 2004, it is 8 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 16,960 gross tonnage it is smaller than 96% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 17 bulk carriers here under the San Marino flag, 0.2% of the 8,138 on the register. The same builder is recorded for 323 other vessels here, 238 of them bulk carriers. Pacific Basin Shipping Limited is linked to 14 vessels on this register. Its MRV returns name it PORT KENNY for 2018–2020 and AYANA STAR for 2023–2025. The reported port of registry changed: Hong Kong (2018–2020), then San Marino (2023–2025).
Its 1,328 t of CO₂ for 2025 is 59% 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 152.1 kg CO₂, 42% below the type median of 260.7 kg. It logged 822 hours at sea against a median of 1,200 hours for its type that year. 3.6% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 6 years with reported emissions, the highest was 2023 (5,994 t) and the lowest 2025 (1,328 t). Its efficiency percentile within the type went from 58 in 2018 to 88 in 2025 (lower is more efficient). Of the 4 sister ships listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 2,863 of 3,241 qualifying bulk carriers by EEOI, at the 88th percentile. The dashed line is the type median, 7.6; this vessel reported 12.2.
Across the 14 ranked vessels operated by Pacific Basin Shipping Limited, the median percentile is 65. This vessel is less efficient than its own fleet median.
EEOI divides emissions by transport work, which for this vessel and year was 108,819,672 tonne-miles over 8,730 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 33.1% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2022, so the series has gaps.
From 2024 to 2025, emissions fell 57.8% while distance sailed fell 35.8%and CO₂ per nautical mile fell 34.3%.
