SKS DOYLES 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 65,830 gross tonnage it is larger than 68% 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 461 other vessels here, 179 of them oil tankers. Its MRV returns name it SKS DOYLES for 2018–2021 and TORM GWYNETH for 2024–2025. The reported port of registry changed: Bergen (2021), then Singapore (2024–2025).
Its 2,615 t of CO₂ for 2024 is 68% below the median of 8,196 t among the 1,808 oil tankers on this register that reported for 2024. Per nautical mile it emitted 537.6 kg CO₂, 32% above the type median of 408.2 kg. It logged 376 hours at sea against a median of 2,020 hours for its type that year. 21.9% of its 2024 emissions were at berth; the median for oil tankers was 7.2%. Across 4 years with reported emissions, the highest was 2019 (7,209 t) and the lowest 2024 (2,615 t). Its efficiency percentile within the type went from 36 in 2018 to 34 in 2024 (lower is more efficient). Of the 2 sister ships listed below with a 2024 return, 2 reported a lower CO₂ per nautical mile than this vessel.
No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2024
Position 536 of 1,566 qualifying oil tankers by EEOI, at the 34th percentile. The dashed line is the type median, 7.6; this vessel reported 6.4.
EEOI divides emissions by transport work, which for this vessel and year was 410,563,579 tonne-miles over 4,865 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2024 was 53.9% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2022, 2023, so the series has gaps.
From 2021 to 2024, emissions fell 1.4% while distance sailed fell 29.8%and CO₂ per nautical mile rose 40.5%.
