HAFNIA SHENZHEN against its type
Built in 2020, it is 10 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 43,693 gross tonnage it is smaller than 59% 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 192 other vessels here, 71 of them oil tankers. The returns for 2021–2025 all give SINGAPORE as port of registry.
Its 2,796 t of CO₂ for 2025 is 65% 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 344.6 kg CO₂, 15% below the type median of 403.2 kg. It logged 926 hours at sea against a median of 2,030 hours for its type that year. 5.2% 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 (5,244 t) and the lowest 2022 (2,048 t). Its efficiency percentile within the type went from 52 in 2021 to 61 in 2025 (lower is more efficient). Of the 5 sister ships listed below with a 2025 return, 2 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 879 of 1,448 qualifying oil tankers by EEOI, at the 61st percentile. The dashed line is the type median, 7.5; this vessel reported 8.3.
EEOI divides emissions by transport work, which for this vessel and year was 337,312,425 tonne-miles over 8,115 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 33.0% higher than in 2021, for EU/EEA voyages only. No return is recorded for 2024, so the series has gaps.
From 2023 to 2025, emissions fell 46.7% while distance sailed fell 56.8%and CO₂ per nautical mile rose 23.4%.That points mainly to how much the vessel sailed, rather than the other.
