SOUTHERN OWL against its type
Built in 2016, it is 6 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 14,965 gross tonnage it is smaller than 93% 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 24 other vessels here, one of them an oil tanker. The reported port of registry changed: MONROVIA (2019), then SINGAPORE (2020–2025).
Its 3,589 t of CO₂ for 2025 is 55% below the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 261.0 kg CO₂, 35% below the type median of 403.2 kg. It logged 1,075 hours at sea against a median of 2,030 hours for its type that year. 10.0% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 6 years with reported emissions, the highest was 2021 (10,180 t) and the lowest 2025 (3,589 t). Its efficiency percentile within the type went from 32 in 2019 to 87 in 2025 (lower is more efficient). Of the 6 comparable vessels listed below with a 2025 return, 5 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 1,258 of 1,448 qualifying oil tankers by EEOI, at the 87th percentile. The dashed line is the type median, 7.5; this vessel reported 15.4.
EEOI divides emissions by transport work, which for this vessel and year was 233,074,026 tonne-miles over 13,752 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 53.5% lower than in 2019, for EU/EEA voyages only. No return is recorded for 2022, so the series has gaps.
From 2024 to 2025, emissions fell 53.8% while distance sailed fell 54.7%and CO₂ per nautical mile rose 2.0%.That points mainly to how much the vessel sailed, rather than the other.
