BW TRITON against its type
Built in 2019, it is 9 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 62,000 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 53 other vessels here, 37 of them oil tankers. Its MRV returns name it BW TRITON for 2019–2022 and HAFNIA TRITON for 2023–2025. The returns for 2019–2025 all give Singapore as port of registry.
Its 13,546 t of CO₂ for 2025 is 1.7 times the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 373.9 kg CO₂, close to the type median of 403.2 kg. It logged 3,408 hours at sea against a median of 2,030 hours for its type that year. 9.5% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 6 years with reported emissions, the highest was 2020 (15,397 t) and the lowest 2021 (736 t). Its efficiency percentile within the type went from 4 in 2019 to 12 in 2025 (lower is more efficient). Of the 3 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 176 of 1,448 qualifying oil tankers by EEOI, at the 12th percentile. The dashed line is the type median, 7.5; this vessel reported 4.6.
EEOI divides emissions by transport work, which for this vessel and year was 2,957,537,118 tonne-miles over 36,231 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 476.2% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions rose 190.5% while distance sailed rose 185.7%and CO₂ per nautical mile rose 1.7%.That points mainly to how much the vessel sailed, rather than the other.
