HAFNIA NORDICA against its type
Built in 2010, it is the same age as the median oil tanker on this register (build year 2010, 2,896 vessels with a known build year). At 31,510 gross tonnage it is smaller than 68% of the other 2,841 oil tankers with a recorded tonnage. It is one of 718 oil tankers here under the Liberia flag, 20.2% of the 3,548 on the register. The same builder is recorded for 307 other vessels here, 48 of them oil tankers. Its MRV returns name it HAFNIA NORDICA for 2018–2024 and ULYSSES I for 2025. The reported port of registry changed: VALLETTA (2018–2024), then Monrovia (2025).
Its 9,352 t of CO₂ for 2025 is 18% above the median of 7,922 t among the 1,704 oil tankers on this register that reported for 2025. Per nautical mile it emitted 281.4 kg CO₂, 30% below the type median of 403.2 kg. It logged 2,876 hours at sea against a median of 2,030 hours for its type that year. 7.8% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 5 years with reported emissions, the highest was 2018 (11,256 t) and the lowest 2024 (265 t). Its efficiency percentile within the type went from 69 in 2018 to 74 in 2025 (lower is more efficient). Of the 3 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 1,068 of 1,448 qualifying oil tankers by EEOI, at the 74th percentile. The dashed line is the type median, 7.5; this vessel reported 10.3.
EEOI divides emissions by transport work, which for this vessel and year was 906,230,620 tonne-miles over 33,237 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 16.9% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2020, 2021, 2023, so the series has gaps.
From 2024 to 2025, emissions rose 3,432.8% and CO₂ per nautical mile rose 8.9%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
