HAFNIA EXPERIENCE against its type
It is one of 237 oil tankers here under the Singapore flag, 6.7% of the 3,548 on the register. Its MRV returns name it STI EXPERIENCE for 2018–2020 and HAFNIA EXPERIENCE for 2023–2025. The reported port of registry changed: Majuro (2018–2020), then Singapore (2023–2025).
Its 1,756 t of CO₂ for 2025 is 78% 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 476.6 kg CO₂, 18% above the type median of 403.2 kg. It logged 313 hours at sea against a median of 2,030 hours for its type that year. 0.0% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 5 years with reported emissions, the highest was 2023 (6,849 t) and the lowest 2024 (593 t). Its efficiency percentile within the type went from 13 in 2018 to 49 in 2025 (lower is more efficient). Of the 8 comparable vessels listed below with a 2025 return, 6 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 716 of 1,448 qualifying oil tankers by EEOI, at the 49th percentile. The dashed line is the type median, 7.5; this vessel reported 7.4.
EEOI divides emissions by transport work, which for this vessel and year was 237,324,324 tonne-miles over 3,685 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 51.4% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2019, 2021, 2022, so the series has gaps.
From 2024 to 2025, emissions rose 196.3% and CO₂ per nautical mile rose 40.0%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
