ASHLEY LADY 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 62,201 gross tonnage it is larger than 57% of the other 2,841 oil tankers with a recorded tonnage. It is one of 237 oil tankers here under the Singapore flag, 6.7% of the 3,548 on the register. The same builder is recorded for 196 other vessels here, 75 of them oil tankers. The returns for 2018–2025 all give Singapore as port of registry.
Its 7,909 t of CO₂ for 2025 is close to the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 544.3 kg CO₂, 35% above the type median of 403.2 kg. It logged 1,541 hours at sea against a median of 2,030 hours for its type that year. 14.0% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 4 years with reported emissions, the highest was 2025 (7,909 t) and the lowest 2018 (2,917 t). Its efficiency percentile within the type went from 34 in 2018 to 74 in 2023 (lower is more efficient).

Efficiency against its own type2023
Position 1,188 of 1,615 qualifying oil tankers by EEOI, at the 74th percentile. The dashed line is the type median, 8.0; this vessel reported 11.0.
EEOI divides emissions by transport work, which for this vessel and year was 623,845,173 tonne-miles over 12,878 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 171.1% higher than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2021, 2024, so the series has gaps.
From 2023 to 2025, emissions rose 15.5% and CO₂ per nautical mile rose 2.3%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
