NORDIC THUNDER against its type
Built in 2017, it is 7 years newer than the median oil tanker on this register, which was built in 2010 (2,896 vessels with a known build year). At 81,308 gross tonnage it is larger than 73% of the other 2,841 oil tankers with a recorded tonnage. It is one of 793 oil tankers here under the Marshall Islands flag, 22.4% of the 3,548 on the register. The same builder is recorded for 461 other vessels here, 179 of them oil tankers. Its MRV returns name it NORDIC THUNDER for 2018–2023 and ULSAN SPIRIT for 2025. The returns for 2018–2025 all give Majuro as port of registry.
Its 1,970 t of CO₂ for 2023 is 74% below the median of 7,491 t among the 1,850 oil tankers on this register that reported for 2023. Per nautical mile it emitted 436.0 kg CO₂, close to the type median of 408.5 kg. It logged 384 hours at sea against a median of 1,807 hours for its type that year. 7.5% of its 2023 emissions were at berth; the median for oil tankers was 8.4%. Across 5 years with reported emissions, the highest was 2020 (10,972 t) and the lowest 2023 (1,970 t). Its efficiency percentile within the type went from 9 in 2018 to 1 in 2023 (lower is more efficient).
No EU/EEA voyages were reported for 2025: zero CO₂ and zero time at sea, left out of the trend and of any ranking.

Efficiency against its own type2023
Position 19 of 1,615 qualifying oil tankers by EEOI, at the 1st percentile. The dashed line is the type median, 8.0; this vessel reported 3.1.
EEOI divides emissions by transport work, which for this vessel and year was 635,341,936 tonne-miles over 4,518 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2023 was 78.7% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2021, 2024, so the series has gaps.
From 2022 to 2023, emissions fell 76.7% while distance sailed fell 78.9%and CO₂ per nautical mile rose 10.5%.That points mainly to how much the vessel sailed, rather than the other.
