NORDIC HANNE against its type

Built in 2007, it is 3 years older than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 24,112 gross tonnage it is smaller than 89% 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 192 other vessels here, 71 of them oil tankers. Its MRV returns name it NORDIC HANNE for 2018–2020, NORDIC TATIANA for 2021–2022 and TATIANA for 2023–2025. The reported port of registry changed: Singapore (2018–2020), then Monrovia (2021–2025).

Its 2,833 t of CO₂ for 2025 is 64% 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 317.1 kg CO₂, 21% below the type median of 403.2 kg. It logged 925 hours at sea against a median of 2,030 hours for its type that year. 13.7% of its 2025 emissions were at berth; the median for oil tankers was 7.8%. Across 8 years with reported emissions, the highest was 2018 (15,078 t) and the lowest 2025 (2,833 t). Its efficiency percentile within the type went from 47 in 2018 to 90 in 2022 (lower is more efficient). Of the 3 sister ships listed below with a 2025 return, 3 reported a lower CO₂ per nautical mile than this vessel.

Reported CO₂ by year

Reported CO₂ in 2025 was 81.2% lower than in 2018, for EU/EEA voyages only.

From 2024 to 2025, emissions fell 30.9% and CO₂ per nautical mile fell 0.2%.Distance is missing for at least one of the two years, so activity and efficiency cannot be separated here.
