BW COUGAR against its type
Built in 2014, it is 4 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 29,737 gross tonnage it is smaller than 75% 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 180 other vessels here, 51 of them oil tankers. Its MRV returns name it BW COUGAR for 2018–2021 and HAFNIA COUGAR for 2023–2025. The returns for 2018–2025 all give Singapore as port of registry.
Its 3,882 t of CO₂ for 2025 is 51% 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 237.3 kg CO₂, 41% below the type median of 403.2 kg. It logged 1,445 hours at sea against a median of 2,030 hours for its type that year. 2.7% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 4 years with reported emissions, the highest was 2023 (6,032 t) and the lowest 2021 (3,450 t). Its efficiency percentile within the type went from 39 in 2018 to 64 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 924 of 1,448 qualifying oil tankers by EEOI, at the 64th percentile. The dashed line is the type median, 7.5; this vessel reported 8.7.
EEOI divides emissions by transport work, which for this vessel and year was 447,278,802 tonne-miles over 16,361 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 34.0% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2020, 2022, 2024, so the series has gaps.
From 2023 to 2025, emissions fell 35.6% while distance sailed fell 22.8%and CO₂ per nautical mile fell 16.6%.
