ALCYONE T against its type
Built in 2010, it is the same age as the median oil tanker on this register (build year 2010, 2,896 vessels with a known build year). At 28,049 gross tonnage it is smaller than 84% of the other 2,841 oil tankers with a recorded tonnage. It is one of 793 oil tankers here under the Marshall Islands flag, 22.4% of the 3,548 on the register. The same builder is recorded for 307 other vessels here, 48 of them oil tankers. The reported port of registry changed: Majuro, Marshall Islands (2019–2020), then Majuro (2022–2023).
Its 5,196 t of CO₂ for 2023 is 31% below the median of 7,491 t among the 1,850 oil tankers on this register that reported for 2023. Per nautical mile it emitted 261.4 kg CO₂, 36% below the type median of 408.5 kg. It logged 1,770 hours at sea against a median of 1,807 hours for its type that year. 3.5% of its 2023 emissions were at berth; the median for oil tankers was 8.4%. Across 4 years with reported emissions, the highest was 2023 (5,196 t) and the lowest 2022 (1,682 t). Its efficiency percentile within the type went from 60 in 2019 to 63 in 2023 (lower is more efficient). Of the 3 sister ships listed below with a 2023 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2023
Position 1,013 of 1,615 qualifying oil tankers by EEOI, at the 63rd percentile. The dashed line is the type median, 8.0; this vessel reported 9.3.
EEOI divides emissions by transport work, which for this vessel and year was 561,128,510 tonne-miles over 19,882 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2023 was 33.6% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2021, so the series has gaps.
From 2022 to 2023, emissions rose 208.9% and CO₂ per nautical mile rose 7.1%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
