BW TAGUS against its type

Built in 2017, it is 7 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 43,072 gross tonnage it is smaller than 60% 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 96 other vessels here, 19 of them oil tankers. Its MRV returns name it BW TAGUS for 2019–2021 and HAFNIA TAGUS for 2022–2025. The returns for 2019–2025 all give Singapore as port of registry.

Its 3,390 t of CO₂ for 2025 is 57% 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 276.9 kg CO₂, 31% below the type median of 403.2 kg. It logged 1,264 hours at sea against a median of 2,030 hours for its type that year. 6.4% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 7 years with reported emissions, the highest was 2023 (6,162 t) and the lowest 2021 (1,640 t). Its efficiency percentile within the type went from 16 in 2019 to 75 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 1,087 of 1,448 qualifying oil tankers by EEOI, at the 75th percentile. The dashed line is the type median, 7.5; this vessel reported 10.5.

EEOI divides emissions by transport work, which for this vessel and year was 322,509,990 tonne-miles over 12,242 nautical miles.

Reported CO₂ by year

Reported CO₂ in 2025 was 41.3% lower than in 2019, for EU/EEA voyages only.

From 2024 to 2025, emissions rose 18.2% while distance sailed rose 20.7%and CO₂ per nautical mile fell 2.1%.That points mainly to how much the vessel sailed, rather than the other.
